Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis.

Solar energy
It is an important source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power and solar water heating to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light-dispersing properties, and designing spaces that naturally circulate air.
The large magnitude of solar energy available makes it a highly appealing source of electricity. The United Nations Development Programme in its 2000 World Energy Assessment found that the annual potential of solar energy was 1,575–49,837 exajoules (EJ). This is several times larger than the total world energy consumption, which was 559.8 EJ in 2012.[3][4]

plz don't copy frm Internet
That was in my net book So I copy it.
In my own opinion wait
ok if you Don't mind what is pollution and ground water
Solar energy is a heat coming from sunlight which give us energy and also to the plants and its called photosynthesis. Now in our Generation or technology solar energy is used to produced electricity. Meanwhile it is not so strong electicity compared to other windmill and water falls
Wait I will answe it in my own opinion
guysss just leave it
i had left
ok
Pollution is an effect of a people doing due to survived their own lives. Example. To eat thier breakfast they need to cook. Fuel is needed so the air is being polluted for using fuel. Then how about travelling ? If they use a vehicle it also produced smoke so pollution is an effect of the human does. The Ground water is a water between soil and bed rock in the ground. Example of that is a well. Well is a deephole in a ground to produce water
