The Alternative Energy Source to Oil Essay -- Renewable Energy Solar P
The Alternative Energy Source to Oil world1.0Renewable Energy is the term apply to describe those capacity flows that devolve naturally and repeatedly in the environment, e.g. from the sun, wind and the oceans, and from plants and the fall of water. It also refers to the dexterity available from wastes and to the emerging clean technology of burn cells.There argon wide ranges of renewable null sources/technologies, varying in technical and commercialized viability. These includeSolar Power (Photovoltaic)Hydro electric PowerHydrogen send away Cells Geothermal Wind PowerNuclear Power1.1The modern convey to harness renewable energy began in the 1970s. It was promoted by concerns over the footing and availability of fossil supplys oil, gas, and ember. Fossil burn downs be finite only coal is predicted to be available in significant quantities at the end of the twenty-first century at current rates of consumption. Using fossil fuels to knuckle under electricity also prod uces pollutants, which can lead to environmental problems (such as back breaker rain and the greenhouse effect).By contrast, renewable energy produces few, if any, calumnious emissions. Exploiting renewable, which at present meet over 2% of the UKs electricity needs, also reduces the rate at which other energy resources ar used up. With the worlds population continuing to grow, renewable energy promises to frivol an increasingly significant role in the future.1.2The estimated oil reserves in the hide outs crust are about 1 trillion barrels. Oil consumption is at 25 billion barrels per category and increasing at 1.5% per year. At current rates of consumption, measured against cognize reserves, there is only a 30-year supply of oil in the Earths crust. Even if the reserve estimate were doubled, it is a moral exigent that the population takes immediate action to develop a sustainable energy economy.Solar Energy2.0Solar energy is quite simply the energy produced by the sun and collected elsewhere, normally the Earth. The sun creates its energy by means of a thermonuclear process that converts about 650,000,000 tons of hydrogen to atomic number 2 every second. The process creates heat and electromagnetic radiation. The electromagnetic radiation (including apparent light, infra-red light, and ultra-violet radiation) streams out into space i... ..., such as natural gas. Practical fuel cell systems are therefore likely to include a fuel processor, which generates hydrogen from hydrocarbons.There are a number of types of fuel cells presently the focus of development workAlkaline fuel cells AFCDirect wood spirit fuel cells DMFCMolten carbonate fuel cells MCFCPhosphoric acid fuel cells PAFCProton exchange membrane fuel cells PEMRegenerative fuel cells RFCSolid oxide fuel cells SOFC3.5Fuels cells are inherently clean and efficient and are uniquely able to get by the issues of energy security and environmental degradation. Now market experience is p resentation that the technology provides a range of critical benefits that no other angiotensin-converting enzyme power generation technology can match.Fuel cells are bland and reliable with no moving parts.They produce no emissions (other than water) when using slight hydrogen and very light emissions when using hydrocarbon or alcohol fuel.They are extremely efficient compared to conventional means of generating electricity typically 40 50%.PEM fuel cells have a very low operating(a) temperature
