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.

Uk Renewable Energy Wind Records In 2014

Uk Renewable Energy Wind Records In 2014
In 2014, the UK continues to set records as it increases the power it generates from renewable sources of energy. In 2014, the electricity needs of more than a quarter of UK homes were powered by wind energy.According to newly released data from National Grid, a record amount of clean electricity was generated by wind power in 2014. Wind power generated enough electricity to supply the needs of more than 6.7 million UK households last year. This represents a 15 percent increase over the amount generated in 2013 (up from 24.5 terawatt hours to 28.1TWh in 2014). Averaged over the course of the entire year, this amounts to just over 25 percent of all UK homes. The combination of large scale wind farms and smaller sites connected to local networks, provided 9.3 percent of the UK's total electricity supply in 2014, up from 7.8 percent the year before.A number of wind energy records were broken in the UK in 2014. In December a new monthly high of 14 percent of all UK electricity was generated by wind. The previous record was 13 percent, it was set in December 2013. There was also a new quarterly record of 12 percent of electricity from wind in the last 3 months of 2014. This breaks the previous record of 11 percent set in Q1 of 2014.
