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.

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.

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

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.
