Now a day energy sources are need of whole world but these energy sources are polluting our environment. Many scientist and technocrats are try to resolve this problem they invent new sourcres for energy but they are still trying to do more. Here is some details about pollution free energy sources .
Now energy is produced from the following sources
- Coal -(Disadvantages: Pollution/Strip Mining)
- Natural Gas – (Disadvantages:Cost and Lack of Infrastructure)
- Hydro – (Disadvantages:Limited Availability/Environmental Concerns)
- Wind – (Disadvantages:Limited Site and Resource Availability)
- Solar Photovoltaic – (Disadvantages:Higher Cost)
- Nuclear – (Disadvantages:Waste disposal)
Among this power sources Solar PV (Photovoltaic) systems effectively deliver 10 Watts per square foot. Not one square inch of new land would be required to site PV. Theoretically, there are adequate residential, commercial, Government rooftops, and parking structures in California to power a substantial percentage of our State’s electrical needs from solar.
At today′s prices, a typical solar system costs approximately $6.00/watt, installed and has an operating life in excess of 25 years. For all intents and purposes, maintenance and operating costs are minimal.
- Solar energy increases the diversity of power and adds stability to a fossil fuel favored energy structure, while reducing greenhouse gas emissions.
- Solar can be quickly deployed at the point of use, reducing the need for additional transmission and distribution infrastructure, and cost thereof.
- Solar operates most efficiently at mid day, when grid demand is at its peak. By decreasing the strain during peak hours, the longevity of existing power plants and infrastructure is extended, lowering further the cost of energy production.
- By deploying solar over time the cumulative effect of the installed base is impressive. Given its 25-year life, within 10 to 20 years, a respectable portion of California’s energy could be supplied by solar.
- Once installed, the cost is fixed. In comparison to traditional sources of energy, the fuel cost is nonexistent, and operational costs are limited. A solar system’s cost is amortized over its life, there are no rate hikes due to fuel or operating cost increases.
- Helps the worlds growing energy needs and is especially an environmentally healthy and helpful choice.
Nice post and this post helped me alot in my college assignement. Thanks you on your information.
