Today, there is a great need for us to focus on alternative forms of energy, because of the energy crisis that we face today. There is a huge necessity to create awareness among people about these alternative sources of energy, which are eco-friendly and can be used limitlessly. Let us know them.

Solar energy is widely known alternative form of energy and is freely available; this can be converted into electricity and used as per the need. To generate solar energy, all we need is a solar panel, which is made up of Silicon. Silicon captures the energy from the sun and converts it into electricity.

We all are aware of water being used to generate electricity, that is hydro electricity. This type of electricity is generated by constructing dams, where rivers flow, and potential energy of the stored water is used. Though dams are very big to look at, their maintenance cost is low and the best thing about water energy is that, it is affordable.

Bio-fuel is a form of fuel that is generated from plants or animals. This kind of fuel is widely used in automobile industry. The process, that is used to obtain bio-fuel is combustion and it is completely renewable.

In the recent times, Hydrogen is used as an alternative energy and has shown promising results when used to generate energy in the cars. In these cars, the hydrogen is converted into electricity by using fuel cell system. This fuel is eco-friendly and is very safe.

Geo thermal energy is a form of energy that is derived from the internal heat of the earth. Steam is generated from heat, and this steam is used to run turbine.

Energy generated from windmill is also another alternative energy source. A windmill is a very huge fan like standing structure. When the wind blows the blades of the mill spins to power the generator. These work easily, but its investment cost is quiet high.
