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.

Sca Tissue Bets On Wind To Power Its Town Of Menasha Office Needs

Sca Tissue Bets On Wind To Power Its Town Of Menasha Office Needs
"With three turbines set, crews raise a fourth one beside the SCA Tissue office building in the Town of Menasha."

"From an article by Michael King in the Appleton Post-Crescent:"

TOWN OF MENASHA - SCA Tissue is at the forefront of renewable energy applications and looking for more opportunities.

On Monday, the papermaker installed the first of four 100-foot-tall, 20-kilowatt wind turbines outside the SCA Tissue Service Excellence Center offices at 1451 McMahon Drive as part of a 300,000 project. The turbines with the 15-foot blades tower over the building, which has rooftop solar panels that were installed a few years ago.

"This is the first commercial wind (turbine project) in the town," said Mike Dillon, SCA Tissue manager of environmental and risk management. He said SCA once again turned to local firms to aid its latest renewable, or "green" initiative.

"The turbines are the first commercial units built by a new Oshkosh company called Renewegy," he said. "Faith Technologies in Menasha is doing the electrical work and the foundation work for the towers was done by our neighbor, Miron Construction."

Once in place, the four turbines will produce 100 to 125 megawatt-hours annually, enough to power 10 to 12 homes each year, but the electricity is being used exclusively in the office building, Dillon said.

"We're actually going to consume every bit of (electricity) in the building," Dillon said. "This is a continuation of our work with renewable energy, looking at new technologies and improved technologies. It's another piece of a (renewable) portfolio we're trying to develop."

SCA Tissue already is looking at solar and wind power options for its converting facility on Ehlers Road in the Town of Menasha and for its Menasha paper mill, along with SCA facilities in Arizona, New York and Alabama.
