They power your car or heat your house instead of using unrenewable resources
yes it is
Yes
Though a non-polluting renewable source of energy, it is not widely accepted today. here's why: When it is hot and the sun is hot, it falls on the solar ray. The heat gets converted into energy through a transformer, and gets stored in a bunch of batteries. When it is night, there is no heeat to get converted to energy, so we have to depend on the stored energy in the batteries. If the energy in the batteries run out, we won't have electricity till the sun comes out again. This goes for cars, and homes.
yes because it is renewable
It is still an new technology, it still has to take it course and see what happens
