Solar power generation

The content of carbon dioxide in the atmosphere has almost doubled over the past years because of the burning of fossil fuels that releases carbon dioxide. As a result climate changes are taking place in the world. There has been an increase in the earth’s surface temperature, melting of ice caps and mountain glaciers and a rise in the levels of water in seas. This is called global warming. Global warming is harming the life of living beings and so necessary steps must be taken to check global warming.

One way of reducing global warming is by keeping the earth cool by injecting some particles into the upper atmosphere or stratosphere.

But this technique of injecting particles also has an affect on the amount and nature of renewable solar energy that reaches the earth. The generation of solar power can take place only in the presence of direct sunlight and not through the use of diffused sunlight. The amount of sunlight reaching the earth and the renewable solar energy generated is reduced by the injected particles in the stratosphere. This also results in less amount of solar power generated.

The injection of sulfur particles into the atmosphere has reduced the production of this alternative power source by almost one-fifth of the total amount that can be produced if proper sunlight in the form of solar renewable energy is available.

Solar power as an alternative power resource currently meets most of the power needs of the world and will also do so in the future. Therefore, techniques must be developed that reduce global warming and also do not affect the amount of solar power generated.
