Huff And Puff Power Your Home With The Wind

The fastest growing alternative energy platform in the United States is the wind. No, I’m not blowing hot air.

Cheap and Productive

Manipulating the wind to generate electricity for your home is cheap, easy and very misunderstood. First, you don’t have to live in the middle of tornado alley to generate electricity from the wind. Second, you don’t need tulips and windmill like you’ve seen in pictures of Holland. Third, smaller wind systems are so simply, you can do it yourself.

Okay, let’s generate some enthusiasm on your part for improving your home with wind power.

1. Small wind platforms can cut your utility bill by more than half.

2. Wind systems can work with barely any wind at all.

3. Most wind systems are so small, nobody will even notice them.

4. You can install a small wind system yourself.

5. A small wind system will run you around $1,000 and pay for itself in a year depending on your current utility bill.

6. Wind power is the fastest growing energy producer in the world.

7. You can get financial incentives for improving your home with wind power.

When talking about wind power, understand that technological advances have dramatically changed the systems. Forget windmills, turbines and large structures. Unless you own a city, you will not be dealing with those. Instead, modern residential wind systems essentially look like weathervanes on top of 30 foot poles. They are no bigger than a couple of feet long, have three blades and are very thin. It is no different than having a flag pole in your backyard, except this one saves you a ton of money.

The wind system works in a very compact an efficient manner. The wind hits the blades and turns them. Directly behind the blades is a small generator, which converts the turning blades into power. The power is then transferred to the ground through basic wiring where you can either store it in a battery or feed it directly back into the utility grid if allowed. If the utility option is available, I recommend you take it since batteries can be the most expensive part of the system.

That’s it. The world’s simplest energy producing system is wind. As long as it exists, you will always be able to tap it for power.

Solar Power For Post Lighting

Solar energy is all around us, but most people don’t notice it. For instance, the power source for many emergency phones on freeways is powered by it. This brings us the subject of solar post lights.

Solar Power for Post Lighting

Solar energy started to come into popularity in the 1970s, when technology advances combined with massive oil price increases to make solar a popular alternative energy source. Back then, the world was just starting to become more aware about the risks of using so many non-renewable resources, and people wanted to decrease their dependence on fossil fuels. Now, solar power is being used by many different people all across the world, both in big and small ways. One of the small, but still important ways it is being used is in solar post lights.

Often, people want to light their driveways or backyards. Aside from running expensive extension cords to lamps, using battery after battery, or running lines in underground pipes, there really weren’t many choices to power their lamps. Now, solar post lights are regularly used by those who want the convenience of not having to change batteries, and those who want to save money on their electric bill.

Solar post lights work by using very small solar panels, which are attached to an energy collector. These solar panels stay out in the sun all day, attached to your post, and they soak up all of the sun’s solar energy. The energy collector in many of the solar post lights is a NiCad rechargeable battery, most of which can go up to 1000 charges! That is about three years. The light that is powered by the battery is an LED light, which takes very little power but emits a bright light. LEDs can last up to 25 years, making solar post lights a very economical investment. These lights will emit their soft glow for many hours during the night, depending on the amount of solar energy they received during the day.

Other advantages to solar lights are that there are no wires needed, so installation is very easy. Also, you can often buy the lights individually, so there is no need to buy a large package of the lights if you only need a few to illuminate your way. Each light runs independent of the others, so if one light malfunctions, the rest will still be there and glowing.

Whether you choose to buy a few or a lot of the solar post lights, they are still the most economical and ecology minded choice for your driveway and fence lighting needs. With a long lifespan and easy installation, these lamps are the perfect thing to shine through the dark of your front yard.

Warming Up To The Idea Of Solar Energy

There’s good news for those who claim there’s nothing new under the sun when it comes to saving on energy bills. Experts say new benefits and current conditions are making solar energy systems a practical reality for a growing number of homeowners.

With rising energy prices and concerns for the environment and about national security, homeowners are looking at solar energy options. A new federal tax credit, plus some state and local incentives, encourages adopting solar systems. The government offers a tax credit for 30 percent of the cost of a solar electric or solar water heating system. There is no cap for business owners; homeowners receive a maximum $2,000 credit for each system installed.

These credits make solar energy systems a feasible solution for hot water heating and electricity production for many building owners. Many homeowners already benefit from solar heating for their pools and spas without government incentives.

“As awareness grows, along with summer air-conditioning bills, we expect thousands more to consider their solar options,” says Brad Collins, executive director of the American Solar Energy Society, based in Boulder, Colorado. “With continued rising energy costs, consumer interest in clean, renewable energy from secure U.S. energy sources, and federal tax incentives, we believe more homeowners and business owners will look for sustainable alternatives,” he adds.

In most states, another advantage of solar electric systems (also called photovoltaic or PV) is the option to send excess energy back to your local utility grid. For example, if you are a residential customer, your system may generate more electricity than you need during the day when your family is away at work and at school. Net metering allows you to send this excess electricity to the grid, spinning your meter backwards, and reducing or offsetting the electricity you use at other times.

Today, solar energy equipment is high quality and reliable; it is backed by warranties from large, reputable firms and installed by experienced contractors. There are also many resources to learn more about solar energy.

“FindSolar.com is a great starting place to learn more about solar energy and to assess the options for your own particular home or building,” says Julia Judd, executive director of the Washington, D.C.-based Solar Electric Power Association. “With minimal inputs, including your state, county, utility, and typical monthly energy bill, the site provides you with estimates of system size, costs, savings and other benefits.”

Renewable Fuels For Alternative Energy

The Germans have really taken off when it comes to renewable fuel sources, and have become one of the major players in the alternative energy game. Under the aegis of the nation’s electricity feed laws, the German people set a world record in 2006 by investing over $10 billion (US) in research, development, and implementation of wind turbines, biogas power plants, and solar collection cells. Germany’s “feed laws” permit the German homeowners to connect to an electrical grid through some source of renewable energy and then sell back to the power company any excess energy produced at retail prices. This economic incentive has catapulted Germany into the number-one position among all nations with regards to the number of operational solar arrays, biogas plants, and wind turbines. The 50-terawatt hours of electricity produced by these renewable energy sources account for 10% of all of Germany’s energy production per year. In 2006 alone, Germany installed 100,000 solar energy collection systems.

Over in the US, the BP corporation has established an Energy Biosciences Institute (EBI) to spearhead extensive new research and development efforts into clean burning renewable energy sources, most prominently biofuels for ground vehicles. BP’s investment comes to $50 million (US) per year over the course of the next decade. This EBI will be physically located at the University of Illinois Urbana-Champaign. The University is in partnership with BP, and it will be responsible for research and development of new biofuel crops, biofuel-delivering agricultural systems, and machines to produce renewable fuels in liquid form for automobile consumption. The University will especially spearhead efforts in the field of genetic engineering with regard to creating the more advanced biofuel crops. The EBI will additionally have as a major focal point technological innovations for converting heavy hydrocarbons into pollution-free and highly efficient fuels.

Also in the US, the battle rages on between Congress and the Geothermal Energy Association (GEA). The GEA’s Executive Director Karl Gawell has recently written to the Congress and the Department of Energy, the only way to ensure that DOE and OMB do not simply revert to their irrational insistence on terminating the geothermal research program is to schedule a congressional hearing specifically on geothermal energy, its potential, and the role of federal research. Furthermore, Gawell goes on to say that recent studies by the National Research Council, the Western Governors’ Association Clean Energy Task Force and the Massachusetts Institute of Technology all support expanding geothermal research funding to develop the technology necessary to utilize this vast, untapped domestic renewable energy resource.

Supporters of geothermal energy, such as this writer, are amazed at the minuscule amount of awareness that the public has about the huge benefits that research and development of the renewable alternative energy source would provide the US, both practically and economically. Geothermal energy is already less expensive to produce in terms of kilowatt-hours than the coal that the US keeps mining. Geothermal energy is readily available, sitting just a few miles below our feet and easily accessible through drilling. One company, Ormat, which is the third largest geothermal energy producer in the US and has plants in several different nations, is already a billion-dollar-per-year business.

Ranting And Raving About Renewable Energy

Renewable energy is not a new concept. While it may appear to be a rather fashionable topic of conversation in certain circles, renewable energy initiatives have been with us since the dawn of man. There is some debate about the accepted definition of renewable energy, but it can be loosely defined as a form of energy that is essentially inexhaustible. Furthermore, the resource is continually replenished by various natural processes identifiable in the natural world.

One key distinction to make when discussing the concept of renewable energy is that of sustainability. One could make the argument that, in the long term, fossil fuels are a renewable energy resource. While the logic stands on its own, this is a failed notion. The central difference between fossil fuels and other forms of renewable energy is that fossil fuels are being depleted at a rate faster than they can be replenished. For this reason, fossil fuels cannot be considered truly renewable. They are simply not sustainable, due to the accelerated rate of consumption.

Some of the more popular renewable energy resources include sunshine, water, and wind. Solar energy refers to the energy that is collected from sunlight. This form of energy is captured using a photovoltaic array, more commonly known as a solar panel. The solar radiation is captured by the photovoltaic array and converted to direct current (DC) electricity. From there, the direct current electricity must be converted to alternating current (AC) for use in most applications. The converted electricity is then stored in a battery for use at a later date.

There are also various forms of energy that exist in water. One of the most commonly acknowledged is that of hydroelectric energy, but there are a number of others including tidal power and ocean thermal energy conversion. Hydroelectric energy generally employs the use of a dam, wherein the energy of the water flow is captured and used to power a turbine. The turbine then generates a supplementary form of electricity. Tidal power attempts to make use of the natural energy potential of tidal activity in the oceans and seas. In simple terms, the high tide is captured and fed through a turbine to generate electricity. Ocean thermal energy conversion attempts to exploit the variances in water temperature, from the warmer surface water to the cooler deep water, resulting in a cyclic heat engine.

Wind power is one of the oldest accepted forms of renewable energy. It has been used for centuries as a source of power, dating back to the creation of the sailboat. The innate potential of wind power was realized a number of years later in the form of a wind mill. In this instance, the kinetic energy of wind is used to drive a turbine which, in turn, generates electricity. Wind energy possesses immense potential for sustainable energy generation, and a number of large-scale development projects are currently underway throughout the world.

One of the greatest challenges facing humanity is to discover a way to reduce our reliance on unsustainable resources, like fossil fuels. Most, if not all, modern industrial societies rely far too greatly on fossil fuels and increasingly, this is becoming an undeniable reality. Wars of conquest are being waged to secure what is left of the world’s oil reserves. If only the resources of the powerful nations were channeled into developing sustainable energy alternatives, as opposed to driving a war machine bent on dominating the oil markets. Our modern way of life is going to undergo some difficult times in the very near future, if this reality continues to be ignored. Ask yourself what you can do to make a difference. You might be surprised at what you can accomplish.

Renewable Energy Trends

When in 2005 the federal Production Tax Credits (PTC) for companies producing renewable power was renewed, it sent a message far and wide that the renewable energy industry was worth getting into, with the promise of profitability, energy efficiency, and social/environmental “good karma” all in one tidy package. The following are some of the latest ways we’ve seen this collective foray into renewable energies take shape.

The Workforce: Businesses are given tax credits for changing over their sources of electricity to certain renewable energies, steadily increasing the demand for workers in every area of the industry – from research and development to manufacturing to distribution to installation, service and support.

More and more states are taking the federal government’s lead and implementing their own public incentive programs and benefit funds to encourage greater renewable energy usage, with the same result. According to a report released by the National Renewable Energy Laboratory, in the five years between 2001 and 2006 the voluntary demand for renewable energies increased a thousand-fold. The bottom line is as clear as sunlight – the renewable energy industry creates jobs.

The Corporations: General Electric, Whole Foods Market, Safeway, Starbucks, General Motors, Kinko’s, FedEx – these are but some of the world-leading companies that have made and continue to make an active and aggressive switch to renewable energies.

In the case of many companies, this comes in the form of purchasing renewable energy credits to supplant their local utility usage. In other cases, the forays into renewable power run deeper, producing their own biofuels, setting up their own wind farms, and investing in research and development into improved renewable energy technologies.

The Military: The Pentagon has ordered all branches of the U.S. military to curb energy use by 2% at all bases and facilities through pursuit of alternative power sources, including wind and solar energies.

The President: President Bush’s ranch, the Crawford Ranch, is equipped with all the latest and greatest in renewable energy resources and operates entirely off the grid.

The World: The Australian government has a stated objective of increasing the proportion of its total electricity production that comes from renewable energy sources by 78% by the year 2010. The United Kingdom’s goals are a bit more modest but praiseworthy nonetheless, shooting for 10% from only 3.6%, also by the year 2010.

The Future: An inventor by the name of Todd Livingstone has a patent currently pending on a technology to harness the power packed into lightning bolt, estimated at 11 gigawatts each. A Canadian engineer believes that his Atmospheric Vortex Engine is the way to tame a funnel cloud (also known as a tornado). The “Manchester Bobber” is a patented new device for harnessing the power of the up and down motion of waves.

Floating wind systems. Harnessing the power of differences in atmospheric pressure between geographically distant cities. Semi-transparent photovoltaic glass used as windows in office buildings. MIT’s self-described “Manhattan Project” for new, renewable sources of power. Installing devices in highway off-ramps that harness the power of vehicles braking. Generate biomass energy from trees downed in hurricanes.

And if we look further down the horizon, what else can we see? Maybe the next big thing will be Focus Fusion, a technology for producing new zero-emission power plants the size of gas stations. Maybe it’ll be Blackligh Power, a technology that harnesses power from particles called “hydrinos” which are even smaller than atoms of hydrogen. Or maybe it’ll be electromagnetic energy. Whatever renewable energy trends we have in store for us next, there is one thing we can all count on: as the demand for these types of renewable power sources continues its steady rise, funding for research and development into new and better ways of harnessing renewable energy will also increase, leading to more efficient and affordable energy alternatives for us all.

Investment Into Alternative Energy Research And Development

The US government must continue to back the expansion of the role of alternative energy research and development and its implementation by companies and homeowners. Although this writer believes in the reign of the free market and that “that government is best which governs least”, our current system has companies and people expecting federal backing of major initiative with direct investment, in the form of tax breaks, rebate incentives, and even direct central bank investment into the alternative energy industry.

The US and its citizenry need to invest all of the time and energy that they can spare to the conversion from a fossil fuel burning society to one that is green for several different reasons. The green economy will not harm the environment or the quality of our air like fossil fuel burning does. We can become the energy independent nation that we need to be by cutting away our need to import oil, especially oil that is produced by anti-American nations such as Iran. Ultimately, renewable energies and extremely efficient energies like atomic energy are far less expensive than the continuous mining and drilling for fossil fuels. If we do not invest in our future now, catastrophe awaits us. We are going to need to consume more energy than ever in our history as we sail into the 21st century and beyond.

Refurbished Solar Panels For Your Home

For many people, buying something new makes little sense if they can get something refurbished for far cheaper. Refurbished solar panels tend to work the same way, but they can cost you in the end unless you understand the situation.

Refurbished Solar Panels For Your Home

Some families would love to try running their households on solar energy, but might not be able to afford the large price tag. Outfitting your home with solar panels can run into thousands of dollars, and that doesn’t include all of the equipment and adapters you need to use solar energy to its fullest. Refurbished solar panels can be a great way to defray the cost of using solar energy, and can also add to the green aspect of using solar energy, as you are not just harnessing the sun’s energy, you re recycling as well.

Refurbished solar panels are sold by many different online and offline retailers. Whether you choose to buy refurbished components from large businesses or surplus items, resellers are able to obtain the solar panels and then sell them to you. You also have the choice of buying broken or partially working solar panels, for those people who would rather build their own solar panels cell by cell. There are even online bidding sites that offer a place for hobbyists and home owners to sell their refurbished solar panels, and other resources such as newspapers often yield ads for refurbished solar energy products.

There are a few things that you should keep in mind when shopping for refurbished solar panels. Older panels will most likely be the cheapest; because newer solar panels are smaller and take up less space. People buying refurbished panels will pay more for the newer models. Therefore, you’ll get the most wattage per dollar by buying the older refurbished solar panels. Some solar panels that are listed as broken may only need simple repairs, such as soldering. Cracked glass or condensation under the glass of solar panels, however, means that the panel will not work and it is probably not worth your time to repair it. Even solar panels that are over 20 years old can still be going strong, so you can take a chance on buying much older solar panels if they appear to be in good condition.

Buying refurbished solar panels, however, comes with a major financial catch. There are massive tax incentives to going solar these days. When I say massive, I mean massive. Various government entities offer thousands of dollars in tax credits and discounts. It is almost universally required that the systems must be purchased new for you to claim these benefits. If you purchase refurbished solar panels, you will miss out. Make sure to calculate the savings of buying refurbished panels versus new before making your decision.

Choosing solar energy is a step that benefits not only your household, but the whole world. When buying refurbished solar panels, you are also helping to recycle what might otherwise end up in a landfill. Given the financial benefits of buying new systems, make sure you calculate the best direction to go for your particular situation.

Investments In Alternative Energy

It is possible to have a portfolio which profitably (that’s the key word, is it not?) invests in alternative energy funds. “Green” energy production is expected to be a multi-billion (in today’s dollars) industry by 2013.

The most recently developed wind-turbine technologies have brought us wind-produced energy which is more cost efficient as well as more widespread. More state-of-the-art wind energy technologies are typically more market competitive with conventional energy technologies. The newer wind-power technologies don’t even kill birds like in days of old! Wind energy production is a growing technology, and companies engaged in it would make up an excellent part of a growth or aggressive growth portfolio.

Next to consider are solar cell, or photovoltaic cell, technologies. These are to be found implemented in pocket calculators, private property lights, US Coast Guard buoys, and other areas. More and more they find their way onto the roofs of housing and commercial buildings and building complexes. Cost is falling. Their energy efficiency (the ratio of the amount of work needed to cause their energy production versus the actual energy production) is steadily on the rise. As an example, the conversion efficiency of silicon cells has increased from a mere four percent in 1982 to over 20% for the latest technologies. Photovoltaic cells create absolute zero pollution as they are generating electrical power. However, photovoltaic cellls are not presently as cost effective as “utility produced” electricity. “PV” cells are not [capable at present for producing industrial-production amounts of electricity due to their present constraints on space. However, areas where photovoltaic cell arrays could be implemented are increasingly available. In sum, costs are going down while efficiency is rising for this alternative fuel technology.

Many alternative energy investment portfolio advisors are confident that alternative energies derived from currents, tidal movement, and temperature differentials are poised to become a new and predominant form of clean energy. The French are actually fairly advanced at hydro power generation, and numerous studies are being made in Scotland and the US along these sames lines. Some concerns center around the problems with the deterioration of metals in salt water, marine growth such as barnacles, and violent storms which have all been disruptions to energy production in the past. However, these problems for the most part seem to be cured through the use of different, better materials. Ocean-produced energy has a huge advantage because the timing of ocean currents and waves are well understood and reliable.

Investments in hydro-electric technology have grown in the last two decades. Hydro-electric power is clean; however, it’s also limited by geography. While already prominent as power generation, the large, older dams have had problems with disturbing marine life. Improvements have been made on those dams in order to protect marine life, but these improvements have been expensive. Consequently, more attention is now being paid to low-impact “run-of-the-river” hydro-power plants, which do not have these ecological problems.

The reality is, the energy future is green, and investors would do well to put their money out wisely, with that advice in their minds.

Energy efficient homes that go easy on the environment are turning heads in Georgia with their low-maintenance appeal, cost efficiency and natural good looks. With Georgia Tech’s recent success in the 2007 Solar Decathlon and world-class community projects like Atlantic Station, Metro Atlanta is well on its way to being a model of eco-building in the Southeast.

Georgia’s green power was most recently demonstrated by Georgia Tech at the 2007 Solar Decathlon. The innovative contest, sponsored by the US department of energy, is a green building competition with an emphasis on solar energy. Twenty teams from universities all over the world were handed the task of building the most attractive and energy-efficient solar-powered home they could imagine.

Over the five day judging period, the Decathlon Homes had to demonstrate the ability to use nothing but solar energy to power a washer dryer, oven, TV, computer and generate hot water. The homes also had to be architecturally sound, marketable and they had to look good.

Though it was their first year to participate in the contest, the Georgia Tech team won 6th place for their innovative light-house, a completely off-the-grid solar powered home. First place went to a team from Darmstadt Tech in Germany. Though the Georgia Tech team didn’t take home first place this year, the house is part of the significant contribution that that Atlanta’s architects and engineers are making to what we know about building smart.

“Many of the advances that are demonstrated in this house will come to the mainstream,” said associate professor Russell Gentry of the Georgia Tech house, “they will have to come to the mainstream if we’re going to save the energy that we promised to.”

The innovations in the Georgia Tech house set a new standard for energy efficiency and eco- friendliness for Atlanta homes. Atlanta already has a number of model solar projects like the EcoManor, the Southern Living Idea House, and the Brookhaven Zero Energy Home.

“35% of the energy consumed in the US is consumed in buildings. It’s important for us to develop technologies that save that energy,” says Gentry. “Everything we do here is about making buildings more energy efficient and smarter.”

The Georgia Tech Light House is steel and wood construction with a modern open floor plan, hardwood flooring, and a semi-transparent solar roof that subtly lets lights into every room in the house while it insulates and generates power. Designed to be easy to build, expandable and accessible, the plans accommodate from one to three bedrooms and up to two baths. The cost of the prototype is $280K.

Digital Electronics And Renewable Energy Go Hand In Hand

Someone once said “It takes money to make money,” and that is mostly true. Today, we might add, “It takes energy to make money,” with reference to all the wondrous digital electronics we use every day to conduct business and create things. Problem is that it can take quite a lot of energy to run all the computers, peripherals, big screen display and multimedia installations in our homes and offices. And a bunch more to keep all those cell phones, digital cameras, GPS systems, iPods and handheld gaming systems charged and ready to go. So while the cost of energy keeps rising, and more and more people realize that climate changes, pollution and diminishing oil reserves demand a move towards renewable energy sources, we consume more and more with all of our beloved electronics.

Does that mean that the very progress that brought us the wonderful world of digital electronics is also digging us into a deeper and deeper hole of energy dependence and spiraling monetary and environmental costs? It doesn’t have to be that way. Business and the environment do not have to be at odds. There is, in fact, a green electronics movement that seeks to make our beloved electronics more energy efficient and environmentally friendlier. The movement covers the entire spectrum from huge international conglomerates pledging to recycle, reuse and conserve, all the way to electronics being more energy-efficient and either bio-degradable or easier to recycle, thus reducing what is now called “e-waste” from millions of tons of landfill to reused and recycled resources.

Saving energy and recycling makes perfect sense, and it’s no surprise that there are now companies devoting themselves to green electronics and energy sustainability. After all, it’s good PR and makes economic sense. But it goes farther than that. There are now even companies that sell both digital electronics AND renewable energy products. It’s easy to see how a firm belief in renewable energy, conservation and sound energy policies may drive an environmentally conscious business owner to sell items like solar and wind energy products as well as digital electronics made by companies that have realized that business and society are interdependent and thus embraced green technology.

What is “green technology?” It can be products certified for low emissions, products certified to be more energy-efficient (like the Energy Star pledge and standard), or products using solar chargers or other energy saving technologies. It can also mean support of companies that are actively “going green” by increasing recyclable content, removing environmentally harmful substances, using renewable energy in the production cycle, and supporting environmental conservation causes and projects.

Why would companies go green? Because it’s not only the right thing to do, but also because it’s an increasing competitive advantage to be seen as a green company that cares about the environment. Just like a lot of consumers reject pesticides and insist on organically grown food products, more and more consumers insist on buying green, energy-efficient technology from companies that care. It’s good to know that megahits like iPhones and Wii gaming consoles are made by such companies.

What we’re seeing here is really an inevitable, accelerating trend towards smarter, greener and more efficient and conscientious consumption. We all must fight waste and embrace clean, sustainable, renewable energy.

Atlanta Green Home Lights The Way

Energy efficient homes that go easy on the environment are turning heads in Georgia with their low-maintenance appeal, cost efficiency and natural good looks.

Passive And Proud Green Energy Ideas For Your Home

Solar energy comes from the sun. A biology class will tell you that in addition to affecting climate and weather, sunlight provides the energy that sustains most life on earth. It also can be harnessed to provide heating, lighting and electricity. Solar power has become a hot topic lately, but this technology is nothing new – Native Americans, people in China and even the early Greeks have historically turned their buildings to the sun for heat.

These early architects were using what is known as passive solar energy. This technique makes the best use of regular building materials to trap heat with no additional mechanical equipment used. Floors, windows and roofs play a role in attracting (or deflecting) the sun’s rays.

There are a number of ways to take advantage of solar radiation, starting with the house’s placement. Having the house face the equator (we’ll assume we’re in the Northern Hemisphere, thus the house should face south) means that it gets the day’s sunlight. Window orientation is also important – for optimal efficiency, most windows should point within 30 degrees of due south. Maintaining a small percentage of north facing windows will ensure that your home is comfortable year round (and not cooking in the summer).

Rock or stone tile floors and brick walls will absorb the solar radiation and continue to give off heat after the sun is gone. While common windows allow heat to escape, special windows with low-e coating, multiple panes, inert gas fill, and/or insulated frames can reduce heat loss 50 to 75 per cent. By sealing your building envelope and insulating well, you will ensure that the heat stays in the house. It can then be distributed through the house using a regular ceiling fan.

Direct sunlight is not the only important light to think of when considering energy use. By using overall daylight to light a space you can cut down the need for electrical lighting and the heat that’s created by it. Artificial lighting has only been the main source of illumination since the 20th century. And using natural light may have added benefits for your physical and mental health. In addition to windows, daylighting makes use of skylights, light pipes (also known as light tubes), atriums, and light shelves to illuminate the interior. This is best considered when building, but with a few small renos your house can be much brighter, naturally!

Passive cooling is another way to cut your bills and become more energy efficient. This is especially useful in warmer climates, where air conditioning can be a major power consumer. Passive cooling refers to using things for shading, to absorb the heat, and goes hand in hand with passive solar energy. It can be accomplished using exterior landscaping choices – trees and other vegetation – or interior/exterior building options, such as shades, blinds or special glazing on windows.

Whether you are building a new home, looking at doing some renovations or just want to cut your energy bill, passive solar energy and cooling techniques are an easy way to incorporated green ideas into your home. With the rising interest in environmental issues, they make an excellent selling feature and they’ll save you money.

Think Green When Planning A Home Improvement Project


When it comes to home improvement, many cost-conscious homeowners think about all of the “green” they will spend. Today, however, they also are able to think about a different kind of green – “green” building.

With soaring energy prices and states adopting regulations that prohibit products that emit harmful fumes, environmentally friendly building has become a hot topic. In fact, organizations such as the U.S. Green Building Council have been formed to establish criteria for incorporating green products and materials into homes.

Here are a few green products or projects to consider.

* Leaky ducts can account for 30 percent or more of wasted energy. Caulking around your doors, windows, moldings, baseboards and vents is an easy and inexpensive project. Choose a high-quality product that complies with regulations governing volatile organic compounds, or VOCs, which are ozone-damaging pollutants. For example,

Polyseamseal All-Purpose Adhesive Caulk has a VOC level of 3 percent and provides a paintable, fast-drying, long-lasting seal. For more information, visit www.polyseamseal.com.

* Ready to add on to that beautiful deck? Need to do some minor repairs? When selecting an adhesive for the job, be sure to choose one that is easy and safe to use, such as Loctite Exterior Power Grab construction adhesive.

The latex-based formula emits no VOCs and has an initial tack that is nine times stronger than traditional construction adhesives. Plus, it is easy to work with for interior applications because it has low odor, is paintable and can be cleaned up with water. For more information on Loctite brand products, visit www.loctiteproducts .com.

* Are you ready to replace your siding? When choosing your siding material, consider the insulation value and the amount of maintenance it requires. Natural cedar siding, for instance, may seem to be a “green” choice, but it has a low insulation value and requires regular painting; thus, it may not be the best choice.

Insulated vinyl siding, such as CraneBoard Solid Core Siding, is an energy efficient solution. It features a foam backing and provides better insulation than wood, fiber cement or traditional vinyl siding. For more information, visit www.cranesiding.com.

* One of the most obvious ways to make any home more environmentally friendly is to use less electricity. The biggest electricity-eaters are appliances and lighting. Buy Energy Star appliances and switch incandescent bulbs with compact fluorescent bulbs to quickly reduce electricity demand.

Going Solar Who Is Who


You’ve made the decision to go with solar energy for your energy needs. In going solar, you need to know who is who. Let’s take a closer look.

Who is Who?

Companies in the solar energy industry come in two main forms. One set provides the systems you need to produce solar energy on your own. A much smaller subset will sell you a form of clean energy.

If you want to skip putting solar panels or shingles on your home, you need to find a company that will sell you power just like a utility. Unfortunately, there isn’t any nation wide company that solely provides solar electricity to customers. If you’re willing to look a bit broader, Green Mountain Energy Company may be for you.

Green Mountain Energy Company is a “cleaner electricity” company. It only buys power produced from wind, solar, biomass, water, geothermal and natural gas. The power is then fed into regional power grids and you tap it from there. The advantage of Green Mountain is you are using cleaner power than a typical utility company, but not completely clean as you find when generating solar power yourself. The biggest downside to Green Mountain is you are still paying utility bills, often more than you would pay to the utility company in your area. That being said, Green Mountain is really the only company of its type.

When people refer to providers, more often they are discussing manufacturers and installers of solar energy systems. In the case of solar energy, there are a few big industry leaders.

BP Solar is one of the largest producers for solar energy solutions for residential, commercial and industrial platforms throughout the world. The company is a true leader in the field and provides simplified solutions for homeowners by combining the sale of solar energy systems with full installation. A very popular company with many homeowners.

Somewhat surprisingly, General Electric is one of the biggest producers of solar energy solutions. The company offers high end commercial solutions and custom made solutions using crystallized silicon solutions. It also offers pre-packaged systems for residential homes.

On the other end of the scale, Uni-Solar is the creator the new solar roof shingles that are gaining popularity with consumers, businesses and government agencies. The shingles sit flat on homes like regular roof shingles, getting rid of the bulky solar panel appearance. The Uni-Solar product is considered a fairly major break through in solar power.

Solar companies come in all types and forms. You can visit our site in the byline of this article to find companies in your area that provide the particular solar solutions you need.

Solar Power Becoming Americas Choice

Solar power is the power extracted from the sun’s energy, which is the sunlight. As the sun provides us sunlight for free, solar power itself too is a renewable, clean and environment friendly source of energy. With rising concerns about depleting fossil fuels and rise in air pollution, the use of solar power as an alternative source of energy is fast gaining popularity. By harnessing and using solar power at home, it is possible to cut down the cost of power bills and extensive use can even make one totally independent in terms of power requirement. This is mainly because sunlight is available for free almost round the year and the best part is that solar panels and other such solar equipment require little maintenance.

But now, one million dollar question arises- that is why, in spite of so many benefits, are people using solar power only sparingly? The answer to this question lies in the fact that the solar powers are largely inefficient. To counter this problem, bigger panels have to be installed and this makes using them cumbersome. Also, some people prefer not to mess with the aesthetic beauty of their houses. Also, the solar panels do not come very cheaply. Moreover, there is the inherent problem of unable to work at night and providing very little power during cloudy days.

With the depletion of fossil fuels, the scientific community has been urged to understand the urgent need to consider upgrading of existing solar panel technology. Now, with continued research and development in those areas, the solar power systems have undergone drastic changes. They have figured out how to make cheaper solar panels and also improve their efficiency.

One of the major milestones achieved in the solar power technology is the invention of photovoltaic cells. They have gone a long way to reducing the size and increasing the efficiency of the solar panels. In a solar panel, the photovoltaic cells are placed on a steel substrate. Each cell is capable of capturing various spectrums of sunlight. The solar photovoltaic panels have overlapped layering of the cells which makes them an efficient source of producing power. The new solar photovoltaic panels use amorphous silicon thin alloy technology.

This solar photovoltaic panel based on the new technology is not that bulky and can be easily placed on the roof of houses. It is many times more efficient than a regular solar panel. Moreover, they don’t look that bad and can be easily implemented without affecting the overall looks of a building.

Another milestone in the road of solar technology is the invention of photovoltaic shingles. They are basically nothing but solar panels which are modified and made into shingles. Photovoltaic shingles can be used as a convenient and aesthetic substitute for large and bulky solar panels. They are implemented in the roofs of houses as normal shingles. They are usually black colored and have the appearance of normal shingles. And they serve the dual purposes of adoring your house as well as harnessing solar power and converting it into electricity for your use. Moreover, they save you the cost of buying extra shingles. In a nutshell, they are good looking solar panels.

Experts have said that the technology of using photovoltaic cells and photovoltaic shingles is a major breakthrough in the harnessing of solar power. Research is going on for further development in the solar power technology and you can expect even smaller and more efficient solar power systems made available in the near future.

Refurbished Solar Panels For Your Home

For many people, buying something new makes little sense if they can get something refurbished for far cheaper. Refurbished solar panels tend to work the same way, but they can cost you in the end unless you understand the situation.

Refurbished Solar Panels For Your Home

Some families would love to try running their households on solar energy, but might not be able to afford the large price tag. Outfitting your home with solar panels can run into thousands of dollars, and that doesn’t include all of the equipment and adapters you need to use solar energy to its fullest. Refurbished solar panels can be a great way to defray the cost of using solar energy, and can also add to the green aspect of using solar energy, as you are not just harnessing the sun’s energy, you re recycling as well.

Refurbished solar panels are sold by many different online and offline retailers. Whether you choose to buy refurbished components from large businesses or surplus items, resellers are able to obtain the solar panels and then sell them to you. You also have the choice of buying broken or partially working solar panels, for those people who would rather build their own solar panels cell by cell. There are even online bidding sites that offer a place for hobbyists and home owners to sell their refurbished solar panels, and other resources such as newspapers often yield ads for refurbished solar energy products.

There are a few things that you should keep in mind when shopping for refurbished solar panels. Older panels will most likely be the cheapest; because newer solar panels are smaller and take up less space. People buying refurbished panels will pay more for the newer models. Therefore, you’ll get the most wattage per dollar by buying the older refurbished solar panels. Some solar panels that are listed as broken may only need simple repairs, such as soldering. Cracked glass or condensation under the glass of solar panels, however, means that the panel will not work and it is probably not worth your time to repair it. Even solar panels that are over 20 years old can still be going strong, so you can take a chance on buying much older solar panels if they appear to be in good condition.

Buying refurbished solar panels, however, comes with a major financial catch. There are massive tax incentives to going solar these days. When I say massive, I mean massive. Various government entities offer thousands of dollars in tax credits and discounts. It is almost universally required that the systems must be purchased new for you to claim these benefits. If you purchase refurbished solar panels, you will miss out. Make sure to calculate the savings of buying refurbished panels versus new before making your decision.

Choosing solar energy is a step that benefits not only your household, but the whole world. When buying refurbished solar panels, you are also helping to recycle what might otherwise end up in a landfill. Given the financial benefits of buying new systems, make sure you calculate the best direction to go for your particular situation.
