renewable energy :: essays research papers

fuel Cell Fuel cells have been known to science for 150 historic period and have become the subject of intense research since World war II. A fuel cell generates electricity by producing a chemical reaction. It consists of two electrodes (cathode and anode), which is also where the reaction occurs. Hydrogen is the basic fuel cell, just now all fuel cells also require oxygen, and both are supplied from away reservoirs. Most of the hydrogen and oxygen used, combine to form a innoxious byproduct, namely water. Therefore, fuel cells generate electricity with very little pollution. It is the direct of the fuel cells to produce an electrical current that can be direct outside the cell to do work, such as powering light bulbs or an electric motor. There are five different fuel cells, truehearted oxide, alkali, proton exchange membrane (40-50% efficiency), phosphoric acid, and molten carbonate.Biomass Energy This is one of the oldest denotations of brawniness known to man. Biomas s strength is energy from organic matter. The organic matter contains stored sun in the form of chemical energy. Biomass fuel, which can be a liquid, solid, or gas, comes from plants, residues from agriculture or forestry, and the organic component of municipal and industrial wastes. dismantle the fumes from the landfills can be used. When the fuel is burned, the energy is released. The use of this energy has potential to greatly reduce greenhouse gas emissions. The waste generates slightly the same amount of carbon dioxide as fossil fuels but as the plants grow (for biomass purposes), carbon dioxide will be removed from the atmosphere. This is the major radical of energy in the developing world.Wind Energy Surface rail line currents that are warmed by solar rays create wind, which is an indirect source of energy. Wind farms consist of many
