Solar energy-a green energy source


Solar energy is a source of green energy does not harm the environment and renewable is. We can benefit from this energy have been used for years, including homes and buildings were designed to take advantage of the sunrise. This is the so-called passive use solar energy. Of course, there are many active use of this energy, we should be used more widely, particularly because of this, is the most abundant source of hope.

The two most active use solar energy becomes established, are solar panel s to generate electricity and solar panel s hot water. Solar Panel to generate electricity using photovoltaic cells to convert solar energy into current (DC) electricity.Converter used to change the DC to AC (AC) batteries are used to store together with a controller to ensure that the batteries are not over or undercharged.

Solar Panel s hot water comes in two forms, evacuated tubes and collectors flat plate. These panels allow the rays of the Sun, heat the water stored in a bottle of hot water.This means that without the use of the boiler, so long as the sun shines you can have hot water in the summer months when it is dull, you can use the heater immersion in the network of the cylinder. There is a possibility to save to a third country on account of electricity and this means that you will be less pollution.

Many simple applications solar energy have been around for years, such as calculators, light for our gardens, battery charging and even experimental cars have been incorporated sunrise. Satellites have been sent to the place, which are powered by solar panel s. Despite growing concern about environmental pollution around the world, Governments are in most cases still slow.

Some Scandinavian countries of Europe windmill s have been used by many years, but only in recent months that the United Kingdom, 40% of the resources of the European wind licences have been issued on a large scale offshore wind farms.Solar projects are now advanced in countries such as Spain, France, Germany, Japan and South Korea.United States and United Kingdom were free to adopt a green source solar energy.Grants are available for installation solar panel s, but when it is considered that in Great Britain, for example, approximately 25% of the pollution comes from homes.

There are many which are still possible. Governments should encourage the use of a wide green energy and especially the Sun by the owners of the houses still installation prices are relatively high, but at least now anybody now you can build your own solar panel s home not only they will be to reduce economically increase their carbon in this way, but also save money accounts power says that it should be again on the increase and up to a maximum of 80% of the savings available when using solar panel s to generate electricity and to the third when employing solar panel s heat water, is something we all consider.
