Renewable energy resources include the resources which are regularly generated or created by natural processes or can be generated by processes such as farming. These include a range of different sources such as hydro power, solar power, wind power, geothermal power, tidal power, vegetable oil, and alcohol made form sugar cane and other vegetable products. Different sources of renewable energy present different advantages and disadvantages. However one common advantage of such sources is that they don’t get depleted with with use. Also most of the renewable energy sources produce energy without creating environmental pollution in form of exhaust gases from burning of fuel. Burning of Alcohol produces much less pollution. However, use of vegetable oils as fuel can be as polluting as the non-renewable energy source. The biggest disadvantage for most of the sources is that technology for producing energy economically on a large scale is not available. Also while there is no depletion of these source of energy, there is limitation on the total rate of power that can be generated. Also this maximum rate is also fluctuates from time to time. For example solar power is available only during the day, and hydro-power availability fluctuates with availability of water for generation, which fluctuates heavily with seasonal variations.
The non-renewable energy resourcesprimarily refer to the energy that is available form burning of fossil fuel such as coal and petrol.The two biggest disadvantages of this sourceare the limited stock of such fuel in the world, and pollution. Fossil fuel stocks have been created by earth’s natural processes over millions of years. The rate at which we are now using these resources is very high, while the rate of creation of such new stocks is practically zero. In such condition the humanity is likely to run out of the stocks of non-renewable fossil fuel in foreseeable future. Also burning of fossil fuel creates environmental pollution which is likely to have very serious negative impact on the very existence of humanity.The biggest advantage of fossil fuelis availability of a very well developed technology for producing and using them.

Solar is the word for sun-a powerful source of energy that can be used to heat, cool,and light our homes and businesses. The most commonly used solar technologies for homes and businesses are solar water heating our houses. This power could be provided by the sun. One percent of the solar energy that reaches the Earth is enough to provide for the total population. Many countries are already using solar energy. Solar panels are placed on the roof of a house and the sun’s energy is used to heat water. The energy can stored for a number of days, so on cloudy days you can use solar energy too. But there is one thing that we have to know. It can’t be used if the weather is cloudy or rainy during the time.
