Economic Reasons for the Lack of Progress in Solar Power Plants

On average, forecasts suggest that oil resources will drop over the next 50 years and gas supplies will end in the next 110 years. Hence, access to an inexhaustible source of energy is very necessary. Solar energy, in addition to being inexhaustible, is a source of the enormous energy that available to mankind ; It is also available in most parts of the world and it is clean energy. The word Solar is a Latin word for the Sun , which is a powerful energy source. In fact, some of the sunlight that goes to Earth only in an hour, can provide ground energy for one year; Generally, the energy emitted from the sun is about 1.3 * 10 ^ 18 Jule per second. Today, there are many solar power plants around the world. Of course, these plants have not yet expanded for economic and technological reasons .First , we look at the equipment used in the solar power plant then concentrate on economic calculations.
