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.

Wind Siting Bill Passes Major Legislative Hurdle With Strong Bipartisan Support

Wind Siting Bill Passes Major Legislative Hurdle With Strong Bipartisan Support
"From a news release issued by Clean Wisconsin:"

Madison, Wis. - Wisconsin could soon see greater growth in the promising wind energy industry after the Assembly Committee on Energy and Utilities passed Assembly Bill 256 today, a bipartisan bill that would encourage growth in the clean energy industry by replacing a chaotic patchwork of local regulations with sensible statewide standards for permitting safe wind farms.

"Wind energy holds the potential to address many of the greatest problems facing our state -it can clean our environment and reduce global warming pollution while reducing our dependence on fossil fuels and creating jobs for hard working Wisconsinites," said Amber Meyer Smith, program director at Clean Wisconsin the state's largest environmental advocacy organization. "With so much to gain, we're extremely encouraged that the legislature seems poised to eliminate administrative barriers holding up the development of this promising infant industry."

As other industries struggled in poor economic times and cut workers, the wind energy industry grew immensely in 2008 - increasing its national workforce by 70 percent to over 85,000 workers. Unfortunately, while wind developers stand ready to invest in Wisconsin's economy and put Wisconsinites to work building safe wind farms, a complicated system of over-stringent local regulations currently puts our state at a disadvantage to neighboring states, holding up more than an estimated 500 megawatts of wind farm development in the state.

Assembly Bill 256 would charge the Wisconsin Public Service Commission with studying and determining safe permitting standards for wind farms, then replacing the current disorganized system that discourages the growth of the wind energy industry with sensible statewide standards.
