Clean energy is energy generated by renewable origins without damaging the environment. Sometimes clean energy is referred to as green energy, and the basic kinds are solar, wind, and water.
The world's governments are looking seriously at investing more into clean energy, not only to reduce pollution, but as an alternative to oil, gas and coal as the main source of energy to produce electricity. The world has been locked into a dependency on the use oil to meet its energy needs, at the ultimate sacrifice to the environment.
Oil, gas, and coal are also limited resources, and have been the cause of many conflicts and war throughout world history. Using the gift of nature found in green energy, every country and people on this planet has access to energy sources generated from solar, wind, and water. So it would become pointless for nations and peoples to fight or go to war over these renewable resources because everyone has access to them.
Clean energy is replenished constantly, and can derive energy directly from heat generated down deep within the earth, or from the sun. Electricity can also be generated by heat sources from wind using windmills or other equipment made to harness the wind power, hydropower stations, biomass power plants, biofuels and hydrogen generators all are renewable energy sources and using the gift of nature to meet the worlds energy needs should be a common sense decision.
Using the gift of nature, clean energy can replace conventional fuels in a number of ways;
Power generation
Clean energy already provides 18 percent of electricity generation worldwide, in the form of;
1) Wind farms utilize wind turbines in wind mills to harness the power in moving air.
2) Hydropower harnesses the energy of moving water to produce hydroelectric energy, Hoover Dam in the United States is an excellent example of this, and even a stream of water or ocean swells can produce substantial amounts of energy.
3) Solar power is energy derived from the sun's heat, heating water or even solar cooking, but the most popular is solar energy from solar cells.
4) Biomass is green energy, through photosynthesis plants capture the sun's energy, then when they are burned to produce heat to make electricity they release this energy acting like natures natural batteries. There are two ways plants can be used to produce energy, by using the residues of plants that are a waste product from other manufacturing processes, or growing plants specifically for energy production.
5) Liquid Biofuel such as bioethanol comes from fermenting plant material, and biodiesel made from vegetable oil and animal fats can be used as fuel for vehicles and electrical generators.
6) Geothermal energy is obtained by trapping heat from deep within the earth; water is heated in this process to produce steam to make electricity.
The presence of mankind is ever increasing on this planet and is continually taking its toll on the earth's resources and impeding the natural ability of the planet to repair itself. Clean energy is the answer not only to mankind's future energy needs but also for the continued health of this planet. Using the gift of nature to produce clean energy may well be the yoke that will allow mankind to coexist with this planet.
