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.

Waukesha Family Wins Home Energy Makeover

Waukesha Family Wins Home Energy Makeover

From a media release issued by Focus on Energy:

On Dec. 31, 2007 Focus on Energy, Wisconsin's energy efficiency and renewable energy initiative, launched a contest to find a Milwaukee area family with a home in need of energy efficient improvements. The contest, named Home Energy Makeover, was sponsored by Focus on Energy in partnership with WITI-TV FOX 6 and awarded one lucky winner with energy efficient improvements for their home, including insulation and air sealing, ENERGY STAR(R) qualified appliances and a new furnace, air conditioner and tankless water heater....

John and Corinne Kangas of Waukesha, Wis., were named the winners of the contest, valued at approximately 20,000, on Feb. 3, 2008 during halftime of the Super Bowl telecast. It wasn't long after the announcement that the Kangas home began its energy transformation.

"We found out we had won the contest when we saw the TV commercial announcing the winner during the Super Bowl. My family was jumping up and down - we were so excited," said Corinne Kangas. "Our home is older, so knowing we won't have to worry about things like the furnace or the air conditioner gives us great peace of mind. Plus, we couldn't wait to learn about the process of making our home more energy efficient."

For several weeks, FOX 6 joined the homeowners on their journey to energy efficiency, covering such details as the energy evaluation of the home, the advantages of ENERGY STAR qualified appliances and the installation of a tankless water heater. Through each step, FOX 6 viewers learned how they could benefit from the same improvements to their homes.

"By identifying what the home needed and then making the necessary improvements, the Kangas family can expect to save approximately 30 percent on their energy bills," said Rich Marshall, Focus on Energy Project Manager. "More importantly, if other homeowners made just a few of the improvements the Kangas family received they could save significantly too."
