How does renewable energy work?
One example is solar power:
The heat from the sun can be used to heat water or air for residential, commercial and industrial use. Sunlight can also provide heating or be converted to electricity using photovoltaic (solar electric) panels. This electricity can be used to operate a multitude of electrical appliances. The sun’s energy (light, heat, ultraviolet) can also be converted into heat using solar thermal (heating) panels.
Wind and flowing water can also be used to generate electricity. The energy from the wind can be harnessed by wind turbines and windmills to generate electricity and also to pump water.
