The use of Solar power


Solar power is the technology of obtaining usable energy from the light of the Sun. Solar energy has been used in many traditional technologies for centuries and has come into widespread use where other power supplies are absent, such as in remote locations and in space.

Really, Solar Power is much spoken nowadays, this technology is actually clean and cheap. There are not many solar power plants, the biggest one is in Mojave Desert in California, USA.



Availability of solar energy

There is no shortage of solar-derived energy on Earth. Indeed the storages and flows of energy on the planet are very large relative to human needs:

  • The amount of solar energy intercepted by the Earth every minute is greater than the amount of energy the world uses in fossil fuels each year.
  • Tropical oceans absorb 560 trillion gigajoules (GJ) of solar energy each year, equivalent to 1,600 times the world’s annual energy use.
  • The energy in the winds that blows across the United States each year could produce more than 16 billion GJ of electricity—more than one and one-half times the electricity consumed in the United States in 2000.
  • Annual photosynthesis by the vegetation in the United States is 50 billion GJ, equivalent to nearly 60% of the nation’s annual fossil fuel use.

James Bratley writes:

Solar power is becoming a way of life for many people across the globe. From isolated communities to inner city suburbs, solar energy is becoming a very popular choice to better the environment.
Solar energy has been in existence ever since life on our planet began. We have been using the strength of the sun in many different ways, past and present. The more modern technique of using solar energy has been through the use of solar panels.
Solar energy is 100% reliable, if our planet did not receive this energy, or if the energy increased or dropped significantly, then the earth would more than likely struggle to support mankind. However, some methods regarding how we use solar energy are by no means 100% reliable.


Larry West adds here:

The sun is a virtually endless source of clean, renewable energy, which should make solar power a logical alternative to finite fossil fuels that pollute the atmosphere and contribute to global warming.

Hopefully these solar power plants will take their place soon and will be used widely in most big countries all over the world.

I think, that it is really clean technologies.
