The price of solar electric systems has fallen rapidly in recent years, making solar energy more accessible than ever. In 2010, the installed cost of residential and commercial solar photovoltaic power systems fell by 17 percent from the previous year, falling an additional 11 percent in the first half of 2011, according to a report by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab). So is now the time to take the plunge?
Well, such statistics don’t mean that solar power systems are cheap. The average cost nationwide last year was $6.20 per watt, says Ryan Wiser, a Berkeley Lab scientist. An average-size home (about 2,000 square feet) generally requires a 5-kilowatt system — approximately a $31,000 investment. “There’s a large up-front cost, but there’s also economies of scale,” Wiser says. “The cost per unit on a smaller system will be higher.” So if you opt for more power — say, a 10-kilowatt system — the price per watt will be substantially lower. Your circumstances could also help: It’s cheaper to install a system on new construction versus an existing home. There are several ways to defray the overall costs. One is through state and federal solar energy rebates. A list of current rebates is available through theDatabase of State Incentives for Renewables and Efficiency. Another is by entering a net metering agreement with your utility company. When your system generates more power than you need, the excess returns to the electricity grid and your meter runs backward. This allows you to receive full retail credit for the power your system generates. A way to avoid up-front costs altogether is to lease. Leasing has become a popular option in recent years, Wiser says, with more than half of new installed systems being leased through companies such as SolarCity, SunRun and Sungevity. How much you can potentially save on electricity depends upon many factors, including the size of the system you choose and your current retail electricity rate. Online calculators, such as Berkeley Lab’s Home Energy Saver, can help you make that determination. They also can help assess other ways to make your home more energy efficient, which is the best first step to take when switching to solar power. “We tell people they really need to look at their building energy use,” says Sherri Shields, a spokeswoman for the Florida Solar Energy Center, a research institute of the University of Central Florida. “The more energy efficient you make your home, the less equipment you need to put on your roof.” If you’re purchasing your own solar panels, as opposed to leasing, it’s best to hire a local solar contractor or an electrical contractor that specializes in solar power. The contractor will take into account many considerations, including how much energy your home uses and potential sites for the panels. The type of roof you have, which direction your home faces and even nearby trees and other shade-producing obstructions all need to be factored in as well when designing a system. “It’s not just something cookie-cutter, out of the box,” Shields explains. Other things to keep in mind? Check with your insurance company to make sure your system will be covered under your homeowners insurance. Sometimes, a separate rider to the policy is required. Also, be sure all components carry the Underwriters Laboratories (UL) mark for quality and safety, and inquire about a truss-mounted system for roof panels — especially if you live in an area prone to severe weather. “We have to be especially careful in Florida,” Shields says. “If it’s not part of the roof structure, it’s going to come falling off.” Still in need of more information? A good basic guide for getting started is also available here, through the U.S. Department of Energy’s National Renewable Energy Laboratory. So put your plan together, go solar, and expect many sunny days in your future.

Cargo Container Homes

Cargo Container Student Residences

Shipping containers can be readily modified with a range of creature comforts and can be connected and stacked to create modular, efficient spaces for a fraction of the cost, labor, and resources of more conventional materials. With the green theme growing in popularity across every stretch of the world, more and more people are turning to cargo container homes for green alternatives for office, and even new home, construction. There are countless numbers of empty, unused shipping containers around the world just sitting on the shipping docks and taking up space. The reason for this is that it’s too expensive for a country to ship empty containers back to the their origin in most cases, it’s just cheaper to buy new containers from Asia. The result is an extremely high surplus of empty shipping containers that are just waiting to become someone’s home or office.

The CORE Home

There is a new type of dome home being developed by Sustainable Living Systems called “The Core Home” Basically, it is a hollow Tubular dome structure surrounded by  wood panels just as in a regular geodesic dome. But the best part of this idea is that there is a coolant fluid running through the Tubular pipe structure with a pump in the top of the dome that keeps the fluid in constant motion. This fluid is then sent to a ground heat sink that stabilizes the temperature. Thus the whole house remains relatively a constant temperature. This fluid transfers the heat or the cool throughout the house. Heats up at the top of the house, and cooled at the bottom. or if it is cold out, collects the heat of the ground, and transfers it through out the structure.

This amazing idea gives the net energy usage as ZERO. since you are using a subterranean heat sink to to keep the house at a relatively constant temperature.  The average temperature of the earth. below the frost line is appropriately  65 degrees. To augment the savings you could use a solar pump to push the fluid through the pipes, and add Solar Panels to create more energy for your home usage.

Freeway Windpower

 Freeway Wind Power

   With the Republicans kicking and screaming as they are dragged along, it seems like the Untied States is finally trying to make some forward progress in alternative energies. The desire to live off the grid has exploded and everyone is wanting to become a part of the trendy new solution to world destruction and fossil-fuel dependency. Many Americans now see that these new technologies not only shrink their environmental footprint but also saves them some cold hard cash in the process. This revelation has brought green living many new converts over the last several years, but without widespread cooperation from the private, corporate, and federal level, change may be too slow to come. Let’s face it, we can’t just wait around until everyone has the money to buy an electric car and put solar panels on their roof. Perhaps it is time to start exploiting some of the United States unnatural, renewable resources.

   One must look no further than the daily commute to work to discover one of our nation’s greatest, untapped resources. According to the Federal Highway Administration, the United States currently has over 45,000 miles of interstate highways hosting millions of travelers each day. Besides the countless tons of pollutants being spilled out of these vehicles’ collective tail pipes, the freeway traffic has one other commonly created resource; wind turbulence. As these vehicles barrel down our nation’

This s highways, at nearly 70 mph, they displace the air around them causing air currents that could be harnessed by wind turbines located in the medians. Our roads could one day be lined with millions of these small, vertical-axis wind turbines turning what is currently a black stain on environmentalism into a serious hope for the future. nearly free, clean energy could be a major factor in easing the national dependency on fossil fuels as well as power millions of homes and businesses around the country.

Alternative energy is the way of the future

Article by Ted

Alternative energy is derived from natural, renewable resources, such as wind, solar and water. Not to be confused with the fact that alternative Power the only thing that is lost at the end of the global warming, global leadership, eliminates the dependency on foreign energy will create millions of jobs (Yes, also in the band of rust) and keep our lives by means of the twenty-first century.

Adour Global alternative energy indexes only businesses that are mainly in the field of alternative energy and companies that alternative Power edge to their main business is excluded.The use of alternative energy is no longer a mystery in our daily requirement for power. discover what alternative energy is and how it can help to save money and the environment.

but the true potential of this title unsaid.Solar has gone from $ 254 per watt in the 1950s to about $ 4 today. It suggests that people go to old methods of extracting energy and consumption in exchange for alleged cleaning methods such as wind, water, solar, nuclear, giant batteries, methane gas, maize (corn) oil, etc..

The Solar Energy Industries Association (SEIA) is the national trade association of solar energy
Power plants using renewable and sustainable energy sources are not burning fuels in the production of electricity, so a reduction in the emission atmosphere-. some people see of alternative energy as a joke, and I think in particular wind power generation is also occasionally.

Windmills have been proposed for power now obtained from natural gas. This type of energy derive their power constantly flowing natural energy and contain examples of hydropower, solar energy and geothermal energy.

Renewable means in such a way that its existence is not permanent. Renewable energy sources, such as biomass, small hydro, solar, wind, geothermal, tidal power and photovoltaic systems, can give you a wider free control. The first of these is the huge investment and federal law amendments which are necessary for the smart grid of renewable energy.

While we are making progress in finding new and renewable energy, we are more than halfway to our goal to move away from our dependence on the oil industry.

Wind energy is long as weak and, thanks to the location driven, impractical has been cancelled. Wind Turbines have a role in the new generation sustainable providers.Now it is important to point out that tidal, wave, solar energy and wind energy requires almost no provisional energy, as opposed to coal, oil, gas, biomass, hydrogen and all the others.”Alternative” energy sources wind, solar, water are all good, but they do not seem to confirm our addictive nature.

Global warming is a big factor in the rise of the alternative Power. alternative energy is not only cost effective and necessary for the foreign policy is also required for the domestic policy, with a view to promoting a sustainable environment and in order to prevent global warming and global catastrophe that global warming is advanced.

Global warming or not, we still need to clean this wreck of a planet. read more about existing alternative energy technologies as good as what the future energy sources can help you to efficiently power from your home or business. Living off the grid is a term used to describe people who are looking for alternative sources of energy to install and do not bind to the traditional electric power stations.

Alternative energy is the way of the future. alternative power is a future idea whose time is over.

A Look At Alternative Energy Funds

Article by Peter Bankss

Traditional energy sources such as oil, coal and natural gas, derived from fossil fuels are used to meet the energy needs of most of the world. Due to the rising cost of gas and heating oil prices, concerns as to how long the supply of fossil fuels can last, and a strong desire to be more self sufficient and less dependent on fossil fuels, the global community has been focusing more and more on alternative energy sources.

Technology used to harness the power of renewable energy sources such as solar energy , wind power, geothermal power and biomass has advanced considerably in recent years. All of these options for alternative energy are now more economically viable than every before. Due to the recent explosion in interest in alternative energy and the increased amount of time and money spent on research and development of alternative energy technology, it is an excellent time to invest in alternative energy funds.

There are many companies that focus primarily on investing in alternative energy funds. The Guinness Atkinson Alternative Fund is a long term fund that invests in equity securities of companies that work with alternative energy or alternative energy technologies. Alternative energy funds with Guinness Atkinson Alternative Fund invests in 40-60 stocks of global companies that use get than 50% of their revenue from alternative energy. This company which focuses on technologies that enable exploration of the potential of alternative energy has seen monumental gains in their alternative energy funds in recent periods.

New Alternatives Fund, which is largely committed to alternative energy, is another alternative energy fund that is doing very well and has seen incredible gains in recent quarters. Many experts believe that we are experiencing an alternative energy revolution that will continue to gain in momentum with increasing technologies and advancement and feel that there could not be a better time to invest in alternative energy funds.

Firsthand Alternative Energy Fund also helps clients with investing in alternative energy funds and specializes in solar, wind, biomass, fuel cells, efficiency and technologies of alternative energy. They feel that alternative energy is an important and promising area to invest in.

Calvert Global Energy Fund is a company that introduced their Calvert Global Alternative Energy Fund in 2007. They focus on active management of all alternative energy funds and employ an active and diverse management approach with financial research analysts and portfolio managers.

The Calvert Global Energy Fund is handled by money managers with exceptional expertise and they also focus on sustainable research for long-term rewards for investors. They invest at least 80% of assets into alternative energy companies. Many companies also offer investment kits to make investing easy and help people get started with alternative energy funds .
