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.

SOLAR POWER IS BEING PUT TO USE AT SPORTS STADIUMS AND RACEWAYS IN THE UNITED STATES

Solar energy in the sports field is beginning to find mainstream adoption. The world of competitive sports has long been known as a major energy consumer. Large sports stadiums require a great deal of electrical power in order to operate, and a growing number of these stadiums are beginning to turn to solar energy to satisfy this need. A new study from the Solar Energy Industries Association shows that the total solar capacity in the professional sports field has grown over the past year.

REPORT SHOWS THAT SPORTS FACILITIES HAVE A COMBINED 21.7 MW OF SOLAR CAPACITY INSTALLED AS OF 2014

According to the report, solar capacity at sports facilities throughout the United States reached 21.7 megawatts in 2014, which is enough to power approximately 3,000 average homes. The study shows that the Indianapolis Motor Speedway is home to the highest solar capacity among all sports facilities. The raceway boasts of 9,000 kilowatts of solar energy capacity. The second largest capacity can be found at Lincoln Financial Field and Pocono Raceway, both of which have some 3,000 kilowatts worth of solar capacity.

Solar Power Continues To Gain Support Because Of Its Economic Prospects

Solar energy is beginning to see strong support largely because of its economic prospects. Adoption solar power reduces the need for energy derived from fossil-fuels, which had been growing more expensive until very recently. Solar power also reduces the environmental impact of those using it. As such, sports facilities can reduce the emissions that they produce every year by distancing themselves from fossil-fuels and embracing renewable energy.

Solar Continues To Find Favor Among Homeowners And Businesses As Well

Solar power is not only gaining ground in the field of professional sports, of course. This form of renewable energy continues to grow in favor among homeowners and businesses that want to make use of clean power. For the residential sector, solar energy systems are often seen as a way to reduce the cost of electricity while also becoming more environmentally friendly.
