Hydrogen Energy

Energy is a quantity that cannot be defined, its existence can only be felt. In simple language, if a system possesses energy, it can do a specific kind of work. There are many forms of energy sources which people can use to obtain work. Solar energy, tidal energy, hydroelectric energy, geothermal energy, wind energy are some of the renewable energy sources which are primarily used for the production of electricity.
