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.

Sun Powered Church A Host Site For Illinois Solar Tour

Sun Powered Church A Host Site For Illinois Solar Tour
The Unitarian Universalist Church of Elgin will host an open houses on Oct. 4 as part of the Illinois Solar Tour.

The Unitarian Universalist Church of Elgin will be one of more than 60 sites in the state that will be holding open houses on Saturday, Oct. 4 from 10 a.m.-2 p.m. for people to learn what it is like to live powered by the sun.

The Unitarian Universalist Church of Elgin, 39W830 Highland Avenue, is recognized as a clean energy leader for their participation on the 2014 Illinois Solar Tour.

The Illinois Solar Tour is a free, self-guided, statewide open house that demonstrates how Illinois homes and businesses are using solar, wind, and geothermal to become energy independent.

Illinois home and business owners with renewable energy installations will be providing tours on Oct. 4. Tour hosts will answer questions on how you can harness the power of the sun and wind to fuel your home and business.

This event is coordinated nationally by the nonprofit American Solar Energy Society in collaboration with dozens of outstanding partner organizations. Attending the tour will allow communities across the country the opportunity to see new and innovative technologies locally that will benefit the environment on a global level.

The tour will be followed by an after party from 4:30-6:30 p.m. at Emmett's Ale House in Palatine including a 2014 Tesla ModelS raffle drawing.

To register for these free events, visit www.illinoissolartour.org.

Established in 1975 The Illinois Solar Energy Association (ISEA) is a non-profit organization that promotes the widespread application of renewable energy through education and advocacy. As the Illinois chapter of the American Solar Energy Society, ISEA is the local resource for educational classes, events, renewable energy related policy developments, local news and access to local renewable energy vendors.
