- Biodiesel
- A diesel-equivalent, processed fuel derived from biological sources. Though derived from biological sources, it is a processed fuel that can be readily used in diesel engined vehicles, which More…
- Biofuel
- 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 More…
- Biomass
- 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 More…
- Direct-Methanol Fuel Cell
- (DMFC) A subcategory of proton-exchange fuel cells where, the fuel, methanol, is not reformed, but fed directly to the fuel cell. Because methanol is fed directly into the fuel cell, More…
- Electric Vehicle
- (EV) A vehicle with one or more electric motors for propulsion. The motion may be provided either by wheels or propellers driven by rotary motors, or in the case of tracked vehicles, by More…
- Energy Conservation
- The idealistic or economic practice of reducing the use of energy. This is done in two ways: Increasing energy efficiency, to output the same level of goods and services with a More…
- Ethanol
- (ethyl alcohol, grain alcohol) A flammable, colorless chemical compound, one of the alcohols that is most often found in alcoholic beverages. In common parlance, it is often referred to More…
- Fuel Cell
- An electrochemical energy conversion device which produces electricity from an external supply of fuel and oxygen as opposed to the limited internal energy storage capacity of a battery. More…
- Geothermal Power
- Electricity generated by utilizing naturally occurring geological heat sources. It is a form of renewable energy. Geothermal power is generally harnessed in one of three ways. Large More…
- Green Energy
- A term used by some environmentalists to describe what they deem to be environmentally friendly sources of power and energy. In particular green energy must be renewable and non-polluting. More…
- Hybrid-Electric Vehicle
- (HEV) A vehicle using gasoline (petrol) or diesel to power internal-combustion engines and electric batteries to power electric motors. They are low-polluting and low-petroleum consuming More…
- Hydrogen Economy
- A hypothetical future economy in which energy, for transportation and electrical grid load balancing, is stored as hydrogen. A hydrogen economy is desired in order to solve the problems of More…
- Hydrogen Vehicle
- An automobile which uses hydrogen as its primary source of power for locomotion. These cars generally use the hydrogen in one of two methods: combustion or fuel-cell conversion. In More…
- Hydropower
- Energy obtained from flowing water. Energy in water can be harnessed and used, in the form of motive energy or temperature differences. The most common application is the dam, but it More…
- Light Electric Vehicle
- (LEV) A type of electric vehicles generally designed for one person and small cargo capacity, range, speed. Electric bikes, electric scooters and mopeds are part of a whole range of light More…
- Moten-Carbonate Fuel Cell
- (MCFC) A high-temperature fuel cell, in the range of 600°C. Their main problem is corrosion, and the need to operate a high-temperature liquid rather than a solid as in the More…
- Nuclear Power
- The controlled use of nuclear reactions to release energy for work including propulsion, heat, and the generation of electricity. Human use of nuclear power to do significant useful work is More…
- Phosphoric Acid Fuel Cell
- (PAFC) A type of fuel cell that uses liquid phosphoric acid as an electrolyte. The electrodes are made of carbon paper coated with a finely-dispersed platinum catalyst, which make them More…
- Polymer Electrolyte Membrane Fuel Cell
- (PEMFC) A low temperature fuel cell which are being developed for transport applications as well as for stationary and portable applications. In the most basic of this fuel cell type, More…
- Renewable Energy Sources
- (RES) The capture of energy from existing flows of energy, from on-going natural processes, such as sunshine, wind, flowing water, biological processes, and geothermal heat flows. Most More…
