Renewable Energy Sources

Recently scientists and engineers have developed methods to capture energy from sources that have unlimited supply. These sources are called renewable energy sources because they can be replenished in a short period of time, during a person's lifeltime. In today's society, we mainly convert renewable energy sources into electricity.

 

	SUNLIGHT: Solar panels to capture the sun's energy. We can use the sun's energy today, because the sun will shine again tomorrow.		WIND: Wind turbines capture the wind's energy. We can use the wind's energy now, because the wind will blow again later.
	TIDES: Tidal stream generators capture the tide's energy. We can use the tide's energy now, because ocean waves keep moving.		RIVERS: Dams enable us to capture the energy of a moving river. We can use the river's energy now, because more rain will fall to replenish the water.
