Solar Power?
Hi,
I have some questions about solar power, it's for a school project. Thanks for all your help in advance.
What is solar power?
How does it work? (Please be as specific as possible and list details)
What is solar power used for? (A list would be great.)
How efficient is solar power?
How cost efficient it is?
What are the advantages and disadvantages?
And anything you find important to share would be greatly appreciated. Thanks.
Solar power refers to the utilisation of the sunlight for meeting our energy needs, which are otherwise met by electricity or coal, oil, gas etc.
There are several ways for utilising solar power:
- photovoltaic cells for producing electricity (very expensive to set up but maintenance free)
- solar water heaters very popular in several countries to produce hot water
- solar cookers for cooking food
Solar power is environmentally very clean - no carbon dioxide, no radiation, no health hazards etc.
but it is very expensive right now.
