Types of alternative energy
When we are talking about differnet types of alternative energies in the world, most of peoples only think about solar power but now there is so many type of different energy to replace electricity, fuel, oil and water. As timing passing lots of sciencetic start looking for alternative energy because short of fuel producing in the world.
Solar power
Solar energy is the light and radiant heat from the sun that influences earth’s climate and weather and sustains life. Solar power is sometimes used as a taxonomy for solar energy or more specifically to refer to electricity generated from solar radiation. Solar energy has been enhanced by humans using a different range of technologies. The Sun’s hydrogen is a finite resource and therefore considered non-renewable.
Biofuels
Biofuel is defined as solid, liquid or gas fuel derived from relatively recently dead biological material and is distinguished from fossil fuels, which are derived from long dead biological material. Biofuels can be produced from any carbon source although the most common sources are phtosynthetic plants. At the moment globally biofuel are most been used to power vehicles, heating homes, and cooking stoves.
Biomass
Biomass, as a renewable energy source, refers to living and recently dead biological material that can be used as fuel or for industrial production. In this context, biomass refers to plant matter grown to generate electricity or produce biofuel, and it also includes plant or animal matter used for production of fibers, chemicals or heat. Biomass may also include biodegradable wastes that can be burnt as fuel. It excludes organic material which has been transformed by geological processes into substances such as coal or petroleum.
Hydro Power
Hydroelectricity is electricity generated by hydropower, i.e., the production of power through use of the gravitational force of falling or flowing water. It is the most widely used form of renewable energy. Once a hydroelectric complex is constructed, the project produces no direct waste, and has a considerably different output level of the greenhouse gas carbon dioxide (CO2) than fossil fuel powered energy plants. Worldwide, hydroelectricity supplied an estimated 715,000 MWe in 2005. This was approximately 19% of the world’s electricity (up from 16% in 2003), and accounted for over 63% of electricity from renewable sources
Wind power
Wind power is the conversion of wind energy into a useful form, such as electricity, using wind turbines. At the end of 2007, worldwide nameplate capacity of wind-powered generators was 94.1 Gigawatts. Although wind produces only about 1% of world-wide electricity use, it is growing rapidly, increasing more than fivefold globally between 2000 and 2007. In several countries it has achieved relatively high levels of penetration, accounting for approximately 19% of electricity production in Denmark, 9% in Spain and Portugal, and 6% in Germany and the Republic of Ireland in 2007.
Wave power
Wave power is the transport of energy by ocean surface waves, and the capture of that energy to do useful work — for example for electricity generation, desalination, or the pumping of water (into reservoirs). Wave power is a renewable energy source.
Tidal power
Tidal power, sometimes called tidal energy, is a form of hydropower that converts the energy of tides into electricity or other useful forms of power. Although not yet widely used, tidal power has potential for future electricity generation. Tides are more predictable than wind energy and solar power. Historically, tide mills have been used, both in Europe and on the Atlantic coast of the USA. The earliest occurrences date from the Middle Ages, or even from Roman times.
Geothermal power
Geothermal power (from the Greek roots geo, meaning earth, and therme, meaning heat) is energy generated from heat stored in the earth, or the collection of absorbed heat derived from underground, Prince Piero Ginori Conti tested the first geothermal generator on 4 July 1904, at the Larderello dry steam field in Italy.
