There are many types of green energy that we can use to supply our daily life such as solar energy, wind energy and bio energy. Firstly, we can use solar energy to supplies our daily life. Solar energy comes from an average star- the sun. It provides enough energy in one minute to supply the world 's energy needs for one year. It can use for solar process space heating and cooling system. Solar process space heating system will provide large quantities of hot water for household uses. Besides that, the solar energy also can use for cooling system that combined with some very complex chemistry tricks to create the cool air. The solar energy also can be used for photovoltaic systems. It uses solar panels to convert sunlight into heat, applies it to a steam generator and then converted it into electricity in order to warm the buildings, heating the water and generating electricity for community use. Secondly, we can use wind energy to supplies our daily life. Wind energy is the fastest growing energy source and consumes no fuel for operation with no emissions and zero pollution to produce the electricity. The most comprehensive study to date found the potential of wind power on land and near-shore to be approximately 72 terawatts. It converting 20% of potential wind energy to electricity only to satisfy the world 's energy demands. It also use in other country such as India. India is the fourth largest generator of wind power in the world
