CAN SOLAR ENERGY BE USED TO PROVIDE HEAT AND ELECTRICITY?

Some people feel that solar energy can be used to produce heat and
electricity by making use of direct solar energy or indirect solar
energy such as windmills
Firstly we will save some money by making use of windmills; it will
also reduce air pollution, the carbon dioxide emissions would be greatly
reduced, the dependence on imported oil could be reduced and solar
energy can least as long as coal and nuclear plants.

In order to make use of solar energy we need solar cells and window
glass systems. When these solar cells are produced it in turn creates
toxic chemicals. One would also need back up systems at night and during
cloudy and rainy days.
