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.

The Financial Crunch And Wind Power

The Financial Crunch And Wind Power
While I've been paying attention to political matters, I've been fielding questions about how the financial crisis could be affecting wind power projects. The News Journal today ran this Bloomberg story about possible delays for speculative wind power projects in Europe:

Offshore wind power projects in northern Europe, key to reducing carbon dioxide emissions, face delays because of a shortage of bank finance.

"Things are being delayed," Maartje van den Berg, a clean-technology analyst at Rabobank International, said in an interview Oct. 22. "We are involved in several projects that were close to financial close and they've just stopped. The banks are sitting and waiting for things to improve."A reader last week asked how the financial meltdown could affect the Bluewater Wind project here in Delaware:

But I was wondering what your thoughts are on the possibility that Blue Water might run into financing difficulties due to the global economic implosion. After all, alternative energy projects are still considered high risk, and given the tightness of the credit markets, I could easily picture a financing problem either postponing or perhaps even killing a large wind power project such as the one Blue Water has planned for Delaware.The Bluewater project is different from the European projects, which don't have the benefit of a long term power purchase agreement or PPA. Financing is much easier when investors see a secure revenue stream, as the Bluewater PPA provides. Fortunately, Bluewater won't need much of its capital right away. The Financial Times reports that parent company, Babcock ">:

Babcock ">While it appears that B&B's overall corporate structure is under pressure, the B&B wind fund, which is separately listed on the Australian stock exchange, is profitable. Also, the PPA between Bluewater and Delmarva Power, with its contractual revenue stream, is in itself an asset. Whatever happens to B&B, I expect Bluewater to find the financing to build the wind farm.
