Solar energy Green energy source

Solar energy is a green energy source because it is renewable and does not harm the environment. This is achieved by converting the sun’s rays into electricity using solar cells.

There are 3 basic approaches to using this type of green energy source: passive, active and using photovoltaic cells.

When we talk about passive solar energy, nothing is converted. What happens is that the design of the building helps to avoid heat loss and make the most of daylight.

This technique can be used in homes because studies have shown that it can reduce heating needs by up to 80% at a lower cost. This means that it is not necessary to turn on the air conditioning or the heating as often and if they all do, we do not consume a lot of electricity from non-renewable resources.

The second approach which is active solar energy is the first way to convert sunlight into heat. You should know that there are particular limitations to this and all it can do is make sure you have hot water.

The 3rd approach is the large scale version and can power an office or an entire home.This is done using solar cells that convert sunlight into electricity. The strolling little ones can be seen in calculators and clocks with the big ones planted on huge acres of land. The only limit to this green power source is the fact that it can only generate power in good weather and sunshine. If it rains, nothing is collected and processed. When this happens, the auxiliary system is activated until the weather improves.

Did you know that one kilowatt of solar energy can produce 5.5 hours of electricity per day?If you have multiple solar cells in place, you will naturally be able to produce enough power to last for several days.

Solar energy is just one kind of green energy source. Over the years we have learned to harness additional resources and these examples include wind power, geothermal power, hydroelectricity and biogas. They are all safe and by using them more often we don’t have to depend on oil which is a non-renewable resource.
