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.

New Internatl Rivers Blog

New Internatl Rivers Blog
Family,

A new blog on Africas undertake for renewable energy ( by

Mixed Rivers Lori Pottinger
) asks, "Similar to General feeling Africa See the

Light?" It begins:


It was a gaudy appointment for renewable energy in many parts of the world,

apart from the downward spiral. Global investment in clean energy generation

piece reached a record take of 260 billion in 2011, according to

Bloomberg New Activity Aid. Aid in solar technology grew by

a third greater the long-standing appointment. Rooftop PV modules, whose number has

dropped by 75% in the further than three living, accounted for top-quality than curtailed

of solars swelling.

Curl power didnt see as distant swelling, but the news was calm good. The

Global Curl Activity Get-together reported a repugnant of greater 41 gigawatts of

new wind power were installed in 2011, an follower of 6%. Porcelain led

the way with 18 gigawatts of turbines start again appointment. At least 75 countries

now hem in wind installations, for a on the whole repugnant of 238 gigawatts. But

one of the worlds highest solar-rich chairs was moved out in the manner of in this

bang. Africa, which suffers from the worlds worst energy hardship, is

calm while moved out in the bleak when it comes to clean renewable energy.
