Biofuels have been around as long as cars have.

A biofuel is a fuel that contains energy from geologically recent carbon fixation. These fuels are produced from living organisms.

Generating Electricity from Wing Waves.

Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind.

Producing electricity from solar energy.

Solar energy is a free, inexhaustible resource, yet harnessing it is a relatively new idea. The ability to use solar power for heat was the first discovery.

Turbines catch the wind's energy with their propeller-like blades.

A blade acts much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade.

Solar energy may have had great potential

Solar technology advanced to roughly its present design in 1908 when William J. Bailey of the Carnegie Steel Company invented a collector with an insulated box and copper coils.

We have been harnessing the wind's energy for hundreds of years.

For utility-scale sources of wind energy, a large number of wind turbines are usually built close together to form awind plant.

Biofuels are produced from living organisms.

In order to be considered a biofuel the fuel must contain over 80 percent renewable materials.

Geothermal energy is the heat from the Earth.

Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma.

Geothermal heat pumps can tap into this resource to heat and cool buildings.

A geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building.

In the future, civilization will be forced to research and develop alternative energy sources.

Possession of surplus energy is, of course, a requisite for any kind of civilization, for if man possesses merely the energy of his own muscles, he must expend all his strength - mental and physical - to obtain the bare necessities of life.

Green Homes Theyre Worth More And Sell Faster

Green Homes Theyre Worth More And Sell Faster
A recent article published by the Master Builders Association of WA outlines the results from a number of surveys on the greater Seattle real estate market. It found that green homes sell for 2-10% more per price point, 20-30% more per square foot and 20% faster than traditional homes! The report was compiled by Cascadia, the Vancouver Valuation Accord and Cushman ">Builders who construct green homes can charge more when they go to put them on the market. This will eventually convince more builders to adopt green building practices.

Home buyers benefit because homes with renewable energy systems significantly reduce the cost of living in a home and often improve comfort and make the home healthier to live in. Right off the bat, many home owners can expect to save 50-70% on their utility bills. Many new features come with generous tax credits whch make the renewable energy improvements more affordable. Lastly, home owners who retrofit their homes to include renewable energy systems can fetch a much higher price for their home when they go to sell it, and the homes move off the market much faster.
