energy technologies like nuclear reactors and hydroelectric dams pose both policy challenges and unfortunate environmental consequences when compared to PV solar. Nuclear reactors create hazardous waste that is piling up at power plants across the nation‚ and by the time the first nuclear waste storage facility might be finished‚ all of its available storage space will already be spoken for. In comparison‚ generating electricity with hydroelectric dams doesn’t result in the emission of greenhouse

These are solar energy‚ wind energy‚ geothermal energy‚ hydroelectric energy‚ tidal energy‚ nuclear energy and biofuel. Solar energy Every year‚ the earth gets more than enough energy from the sun as much as 35‚000 times the total energy needs of man. One-third of this solar energy is either absorbed by the outer

Electricity generation is the process of creating electricity from other forms of energy. The fundamental principles of electricity generation were discovered during the 1820s and early 1830s by the British scientist Michael Faraday. His basic method is still used today: electricity is generated by the movement of a loop of wire‚ or disc of copper between the poles of a magnet.[1] For electric utilities‚ it is the first process in the delivery of electricity to consumers. The other processes‚ electricity

Renewable Energy INTRODUCTION/BACKGROUND Renewable energy is a new concept to some people but in actuality it has been around and talked about for many years. What it is is energy that comes from a source that is not depleted when used‚ and can be replenished. Some of these sources are wind‚ rain and sunlight. Renewable energy can replace the common standard fuels humans use in the generation of electricity‚ hot water and heating‚ and motor fuels (“How Solar Energy Works

legislations and newly appointed lake guardians put in place by the government were a direct result of the campaign and is considered the birth place for New Zealand’s environmental awareness. The hydroelectric potential of Lake Manapouri had been noticed for a long time‚ but developing the lake into a hydroelectric energy supplier would require the Lakes water levels to rise tremendously. In 1960 the Government negotiated with Consolidated Zinc who was after cheap energy to power an alumiunm smelter at

companies that abide by the law. When farmers need more land for cattle ranching or soya fields‚ they usually just chop down more trees to get more acres for fields or pastures. Another cause of deforestation is hydroelectric dams. According to How Stuff Works‚ the workers building these dams flood acres of land‚ which causes decomposition and release of greenhouse gases. Furthermore‚ deforestation impacts the Earth in a lot of ways. It causes soil erosion; it reduces biodiversity‚ and global warming
