In a world of increasing energy demand, decreasing fossil fuel Essay

In a manhood of increasing energy demand, decreasing fossil fuel supplies and increasing greenhouse gas emissions. What scientific, engineering and proficient - Essay ExampleMany of these technologies and sources of energy have already experienced a significant core of research and acceptance. The migration from fossil fuels will involve multiple sources, local generation, and a variety of new technologies to big businessman the world into the 21st century.The energy crisis is not a national problem, but is a challenge veneer every nation in the world. While eighty percent of the worlds energy needs comes from fossil ground fuels, the technologies to sustain the menstruation level of use, reduce the CO2 emissions, and develop cleaner coal are unsounded in their infancy and may eventually prove to be impractical (Evans 2007, p.6). In addition, the existence of erect concentrated oil supplies has created an unstable political situation that keeps the worlds supply of energy at risk. Nuclear generated electricity has received some renewed interest in recent years based on alter safety records, but the problem of the safe disposal of nuclear waste is yet to be solved. Our current transportation systems may require substantial modification to run on the fuels of the future. The challenge that faces the world is to give notice away from the current uses of oil and utilize locally generated energy based on local renewable resources.solar energy is at the top of the list as an abundant source of sustainable energy. It is visible(prenominal) almost everywhere in the world and can be harvested on a local level. solar power can be used in its direct form as heat and sparkle as well as easily converted to electricity through the use of photovoltaic cells. Solar energy requires relatively little advanced technology or engineering to harness its benefits. Though solar energy is widely distributed throughout the world, it is a low density energy and requires the collection of the suns rays over a large area to be efficient (Evans 2007, p.82). This makes the large scale production and centralized distribution of
