Introduction
Renewable energy which are abundant such as the solar radiation from the sun is a good example are those resources which are available in large quantity across the country(Pakistan) unlike non- renewable resources which are depleting at a fast rate. The energy of the sun is generated from the nuclear fusion of its hydrogen into helium, with a resulting mass depletion rate of approximately 4.7 × 106 tons per second. The earth’s population currently needs 15 terawatts of power in total, but the solar radiation that reaches the earth on an amount to 120,000 terawatts. Hence, just a fraction of the suns energy received by the earth will cover the amount of energy requirements.
About 36 years ago, the world experienced a major oil crisis which resulted in increased demand of developing alternative energy resources, which can be renewable and environmentally friendly. With due to the many problems such as the increase in oil demand accompanied with oil price rise, exhaustion of oil reserve, reduced obtainability of fossil fuel, ozone layer depletion, health hazards, relatively tangible problems of aesthetics to problems of environmental conservation, and global climate change and other air pollution issues caused mainly by burning of these hydrocarbon as a source of heat energy, has led to the drive to use …show more content…

For a cost of $25, people could save about $9 a year in coal costs. It was a simple batch type solar water heater that combined storage and collector in one box. William Bailey in 1920 's designed, manufactured and sold the first thermosyphon systems with the tank on the roof and the collector below. One of the largest commercial systems in California was installed for a resort in Death Valley. Florida company bought the patent in 1923 and the solar hot water industry began in the coastal cities of central Florida and southern
