Methods of generating electricity-
1. solar energy/Solar power is obtained from the energy of the sun. Solar technologies use the sun's energy and light to provide heat, light, hot water, electricity, and even cooling. The energy from the sun is not always available and it is widely scattered, however, solar power is renewable and environmentally friendly. There are several solar technologies, for exampale
*photovoltaic solar cells, which directly convert sunlight into electricity.
2. Wind energy/Wind power uses the energy contained in the wind for practical purposes like generating electricity, charging batteries, grinding grain or pumping water. A wind turbine is very similar to a windmill; they operate together in wind farms to produce electricity for utilities. Homeowners or remote villages can use smaller turbines to produce energy. Wind power is also a renewable resource and environmentally friendly.
