Solar power

We have to depend on the alternative power like solar energy, wind energy, tidal energy and geothermal energy in order to secure our basic needs. The alternative source of energy is also called renewable source of energy. Now we can see how solar power helps to satisfy our needs. The generation of electricity from sun rays is called solar power. This can be done directly with the principle of photovoltaic. The principle focuses the energy of sun to boil water which is used to produce power. Comparing to other alternative power, solar power is used mostly for residential purposes. It is free from intoxicants and green house gases. Wind energy is also considered as another form of alternative power. It is known for oldest and cleanest source of energy. The energy obtained from the wind is called wind energy. Here the wind turbines are used to produce large amount of energy. The place where we mount wind turbines can also used for other purposes like farming, grazing etc. The petals of turbines are rotated and thus the energy is produced. The other forms of energy are hydro electric power, nuclear energy and bio fuels. Bio fuels are any fuels which are produced from plants and animals. These also include wood, wood carvings, wood chippings and animal excrement.
