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 Approves World Biggest Offshore Wind Farm Project

Uk Approves World Biggest Offshore Wind Farm Project
Plans to build the world's biggest offshore wind farm has just been approved by the UK's energy secretary. The massive offshore wind farm, named the Dogger Bank Creyke Beck project, will be located around 130 km off the coast of the East Riding of Yorkshire.

It will actually comprise of two offshore wind farms (Creyke Beck A and B.) with an installed capacity of up to 1.2GW each. But once built, it will act as a single wind farm and have up to 400 turbines generating a maximum of 2.4GWh per year - enough electricity to power almost two million homes. This means that this wind farm alone would fulfil 2.5 percent of the UK's total electricity needs.

The offshore wind project is also expected to boost the local economy. The government estimates that the wind farm will directly create up to 900 green jobs in Yorkshire and Humberside.

"Making the most of Britain's home grown energy is creating jobs and businesses in the UK, getting the best deal for consumers and reducing our reliance on foreign imports," Energy and Climate Change Secretary Ed Davey said. "Wind power is vital to this plan, with lb14.5 billion invested since 2010 into an industry which supports 35,400 jobs."

RenewableUK, the wind industry association, says the project could create up to 4750 direct and indirect jobs and generate more than lb1.5 billion for the UK economy.

It's estimated that the two offshore wind farms will cost somewhere between lb6 billion to lb8 billion.

But the project could face construction problems and delays as it would be the furthest offshore farm that have ever been attempted. RenewableUK's Director of Offshore Renewables Nick Medic said: "It will surely be considered as one of the most significant infrastructure projects ever undertaken by the wind industry. A colossal wind energy power station right in the middle of the North Sea, comprising hundreds of offshore wind turbines over 80 miles off shore."

"It is a project that pushes the offshore engineering envelope - demonstrating how far this technology has evolved in the ten short years since the first major offshore wind farm was installed in North Hoyle just 5 miles from shore."

A date for when construction starts has not yet been set, but is likely to be years away. The Forewind consortium, which the project is being developed by, has yet to make a final investment decision. The consortium includes the Scottish and Southern Energy, Germany's RWE, and Norway's Statoil and Statkraft.
