Solar Energy
Many scientist believe that solar energy is the future fuel. To cut down electricity bills, we should use solar energy. You can choose a full solar electrical system and completely remove yourself from the local power supply company. Solar systems can heat the water in your homes to fill your hot-water tank. Almost every electronic device that contains GPS or receives information via satellite such as cell phones, use some of the oldest solar technology around. Satellites that link us to most mass forms of media directly or indirectly use the sun’s rays to power them.
Wind Energy
The earth is a source of many forms of energy such as hydro, biomass, nuclear and geothermal. Wind energy is a source of energy which is free, very abundant and environment friendly. Wind turbines are one of the power generating devices, which utilize wind energy to generate power. This electricity is used to run electric devices and or stored in the batteries. Many countries use wind energy to power a pump water from the ground. The wind energy is also used to power the sailing ships in the sea. A more enjoyable use to wind energy is for sports and activities that rely on the power of wind.
Hydro Energy
Like wind energy, Hydro energy is mostly used for electricity generation and accounts for almost 20% of the total global electricity production. Hydro- power is also used to store energy. Hydro electricity is one of the cheapest and nonpolluting sources of power. It is much more reliable than wind and solar power. The most common type of hydro-electric power plant uses a dam on a river to store water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity.
