Solar Energy is used for heating buildings and water, and produces electricity for buildings, also.
The function of solar cell is to convert the energy from the sun into electricity. This is commonly referred to as a photovoltaic cell.
Using solar energy is especially appealing because it is free. It is also environmentally friendly. Active solar techniques include the use of photovoltaic panels and solar thermal collectors to harness the energy.
we use it for regular energy appliances without wasting electricity and hurting the earth and we use the sun instead.
60 percent Generally, people in the states that get most sunshine (Southwest, Great Plains, California) use the most solar energy resources.

There are a few drawbacks to solar energy. One main drawback is the sun only shines for a half a day and there is not any really good way to store it up during the day to use at night. Then of course even during the day clouds may block the sun. The other drawback is that the methods use to convert the solar energy (solar panels) are very inefficient. That means you need an awfull lot of them to get a usefull amount of energy. This takes up a lot of space and it also adds to the cost. Even though the sun's energy is free it still costs more (for now) to convert solar energy to electricity then it does to convert chemical energy from oil, gas or coal.

why is it important to use solar energy in Pakistan
66,987,417,86 people use solar energy
If I had access to solar energy I would use more of it.
Only about 15% of Canadians use solar energy. Nikka.
the most important use of solar energy is to make electricity.
Solar energy trapped from the sun is very useful to make electricity for use in homes. It is an alternative energy source for when the oil, coal and natural gas reserves run out. It is also a very eco-friendly energy source unlike fossil fuels because it doesnt release toxic fumes. The only drawback in using this energy soure is that its very expensive to maintain as the building of solar panels costs a lot of money.
