Renewable energy Renewable energy Active solar is a term which refers to the use of solar energy to "actively" convert the energy in sunlight into other forms. It is contrasted to passive solar which refers to certain architectural design elements by which buildings make use of the sun's energy for heating, and/or cooling. ...more on Wikipedia about "Active solar"
American Solar Challenge is a solar car race across North America. Originally called Sunrayce, organized and sponsored by General Motors in 1990, it was renamed American Solar Challenge in 2001, sponsored by the United States Department of Energy and the National Renewable Energy Laboratory. Beginning in 2005, it is now called North American Solar Challenge with the addition of co-sponsor Natural Resources Canada. It is customarily held once every two years in the summer, though there was a three year gap between the first two races. Teams from universities in the United States and Canada compete in a long distance test of endurance as well as efficiency, driving thousands of miles on regular highways. ...more on Wikipedia about "American Solar Challenge"
The aquanator is a proprietary device using aquafoils (an underwater version of airfoils) to generate electricity from water currents. These devices can be likened to underwater windmills. Unlike traditional tidal power, no weir is used to obstruct the flow of water. Such weirs can potentially disrupt the marine ecology. ...more on Wikipedia about "Aquanator"
The Banki turbine (also known as the Michell, Crossflow or Ossberger turbine) is a hydropower system similar in appearance to an over-shot water wheel. Unlike the water wheel, however, it uses a nozzle and blades instead of buckets. The "middle" of the Banki turbine is left open and the blades that would normally form the walls of the buckets are angled. It is, in effect, a "leaky" water wheel. ...more on Wikipedia about "Banki turbine"
Bioalcohol is alcohol obtained from biological sources, not from petroleum. Examples include methanol and ethanol. It is used most often as a blend of biofuel with petroleum although some new cars are able to use BA100 (Bioalcohol 100%). ...more on Wikipedia about "Bioalcohol"
Biodiesel is a biofuel made from renewable materials such as vegetable oils or animal fats. It is biodegradable and non- toxic, and has significantly fewer emissions than petroleum-based diesel ( petro-diesel) when burned. Biodiesel functions in current diesel engines, and is a possible candidate to replace fossil fuels as the world's primary transport energy source. ...more on Wikipedia about "Biodiesel"
A Biodiesel processor is a combination reaction vessel and still for producing biodiesel from vegetable oil. ...more on Wikipedia about "Biodiesel processor"
Biodiesel production is the process of making biodiesel, a liquid fuel source largely compatible with petroleum based diesel fuel. The following steps can be performed in a small, home-based biodiesel processor, or in large industrial facilities. The process is similar in either case. ...more on Wikipedia about "Biodiesel production"
Biodiesel is a fuel consisting of alkyl --usually methyl or ethyl-- esters and can be used simlilarly to diesel fuel such as in diesel engines. Like a recipe for making a cake, a biodiesel recipe specifies a quantity of every ingredient required, and the steps for combining and processing them to make biodiesel fuel. ...more on Wikipedia about "Biodiesel recipe"
A biodigester is a machine used for the production of biogas, a mixture of gases created by methanogenic bacteria digesting organic matter in an anaerobic condition. A biodigester is often also referred to as a biogas chamber, a biogas plant or an anaerobic reactor. Biogas is used as a substitute for natural gas and propane in a range of situations from cooking, heating, and lighting, to electricity generation, and vehicle fuel. Biodigesters also produce an effluent slurry that is used as a fertilizer in a range of agricultural applications. Biodigesters are used in many countries to process animal and certain plant agricultural waste. They can also be used as a sanitation system for the processing of human waste. ...more on Wikipedia about "Biodigester"
Biofuel is any fuel that derives from biomass — recently living organisms or their metabolic byproducts, such as manure from cows. It is a renewable energy source, unlike other natural resources such as petroleum, coal and nuclear fuels. ...more on Wikipedia about "Biofuel"
Biomass is organic non- fossil material, collectively. In other words, biomass comprises the mass of all biological organisms, dead or alive, excluding biological mass that has been transformed by geological processes into substances such as coal or petroleum. ...more on Wikipedia about "Biomass"
Biomass to liquid (BTL) is a (multi step) process to produce liquid fuels out of biomass: ...more on Wikipedia about "Biomass to liquid"
Bubble wash is a method of final washing of home-made biodiesel through air agitation. Biodiesel floats above a quantity of water. Bubbles from an aquarium air pump and air stone are injected into the water causing the bubbles to rise. At the water/biodiesel interface, the air bubbles carry water up through the biodiesel by surface tension. Diffusion causes water soluble impurities in the biodiesel to be extracted into the water. As the bubble reaches the surface and breaks, the water is freed and percolates back down through the biodiesel again. ...more on Wikipedia about "Bubble wash" Fast www.shortopedia.com Renewable_energy
The Bull Run Hydroelectric Project is a Portland General Electric development in the Sandy River basin in U.S. state of Oregon. Originally built between 1908 and 1912 near the town of Bull Run, it supplies electrical power for the Portland area. The project uses a system of canals, tunnels, wood box flumes and diversion dams to feed a remote storage reservoir and power house. The entire project is slated for decommissioning, starting in the summer of 2007, due to rising environmental costs. ...more on Wikipedia about "Bull Run Hydroelectric Project"
The Darrieus wind turbine is a type of wind turbine used to generate electricity from the energy carried in the wind. The turbine consists of a number of aerofoils vertically mounted on a rotating shaft or framework. This design of wind turbine was patented by Georges Jean Marie Darrieus, a French aeronautical engineer, in 1927. ...more on Wikipedia about "Darrieus wind turbine"
Deep lake water cooling uses cold water pumped from the bottom of a lake as a heat sink for climate control systems. Because heat pump efficiency improves as the heat sink gets colder, deep lake water cooling can reduce the electrical demands of large cooling systems where it is available. ...more on Wikipedia about "Deep lake water cooling"
Dendro energy is energy generated by burning wood grown for the purpose. It is a carbon neutral activity as the carbon dioxide released in combustion is fixed by the growing tree through photosynthesis. ...more on Wikipedia about "Dendro energy"

Earth Day is a name used by two different observances held annually in the (northern) spring, both intended to inspire awareness of and appreciation for the Earth's fragile environment. Earth Day is in the public domain and open to all persons to shape. Some grassroots Earth Day organizers seek to move the date of the observance to the Summer Solstice, to take advantage of the warm temperatures in the Northern hemisphere (where most people live) to create greater participation. ...more on Wikipedia about "Earth Day"
An electric vehicle is a vehicle whose motion is provided by electric motors. The motion may be provided either by wheels or propellors driven by rotary motors, or in the case of tracked vehicles, by linear motors. The electrical energy used to power the motors may be obtained from a direct connection to land-based generation plants, as is common in electric trains; from chemical energy stored on the vehicle in batteries or diesel fuel; from nuclear energy, on nuclear submarines and aircraft carriers; or more esoteric sources such as flywheels, wind and solar. ...more on Wikipedia about "Electric vehicle" Must see http://www.shortopedia.com
