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.

U S Tariffs On Chinese Solar Cells May Be Reduced By Half After Review

U S Tariffs On Chinese Solar Cells May Be Reduced By Half After Review

U.S. tariffs on Chinese solar cells may be halved after a Department of Commerce review, boosting manufacturer and installer margins with little consumer benefit.The review of 2012 import tariffs recommended that the countervailing and anti-dumping duties levied on most Chinese solar manufacturers be reduced from a combined 31 percent to about 18 percent, the department's International Trade Administration said in its preliminary results released Jan. 2.Manufacturers of solar panels, including JinkoSolar Holding and Canadian Solar, and customers, such as installers SolarCity and Vivint Solar, are likely to see "a substantial potential improvement to U.S. margins," Philip Shen, an analyst at Roth Capital Partners in Newport Beach said Tuesday in a research note.Homeowners who want to install rooftop systems shouldn't expect lower prices, said Shayle Kann, an analyst at GTM Research in Boston, by email. That's because the cost of panels represents less than a third of the total cost.Soft costs, like the costs to install, permit, inspect and finance systems, make up the rest. Panel prices will probably fall about 5 cents by late 2015 into early 2016, he said.That makes a bigger difference for large utility-scale solar projects, where prices can be below 1.50 a watt, he said, compared with 4.40 average cost of residential systems installed in the U.S., according to a report by the country's National Renewable Energy Laboratory.The U.S. and China are caught in a dispute over the role of government in aiding renewable energy companies that originated with a case brought by SolarWorld, a German solar manufacturer with a factory in Oregon. SolarWorld asked the Commerce Department in 2012 to apply tariffs to solar cells imported from China.After the tariffs kicked in, imports of panels with cells made in Taiwan boomed, and SolarWorld said a year ago that Chinese makers had shifted production to skirt the duties.The final determination is not expected until early May or June, said Kann. The biggest impact will be on new imports, with shipment cash deposit rates likely to drop to about 15 percent, Kann said.Chinese solar companies are required to set aside a cash deposit equal to the percentage of duties owed on products being imported to the U.S. that will be refunded if the final determination rate is lower.A World Trade Organization body said last month U.S. duties on panels made in China violated trade rules, reversing an earlier finding, in response to China's appeal of a WTO finding earlier this year.The Obama administration said Dec. 17 that it will set duties on solar products from China and Taiwan that may exceed more than 200 percent combined. The Commerce Department also completed a plan to include in the tariffs any solar panels assembled in China, regardless of the origin of the cells.The U.S. International Trade Commission must rule on this last step before the tariffs go into effect. A decision is due next month.
