What is Renewable Energy? It is energy (electricity or heat) that is generated from resources that will not run out. Today's technology can capture the power of the Sun, the wind, the tides, running water and even the heat of the earth.

In this section you will find information about the working, applications and a rough guide to the costs of the following technologies:

	There are three main ways of capturing the power of the Sun: - Passive solar design : More information...
	- Solar photovoltaic (PV) : converting the light from the sun into electricity. More information...
	- Solar thermal : using radiation from the Sun to heat water. More information...
	Wind power generation : the conversion of the kinetic energy in the wind to mechanical energy in order to generate electricity. More information...
	Biomass : extracting heat energy from plant and animal matter. More information...
	A combined heat and power unit simultaneously produces both heat and electricity from the same fuel. More information...
	Hydropower is the generation of electricity by harnessing the power of moving water using a water turbine. More information...
	Ground Source Heating : Using the natural heat of the earth for heating and cooling. More information...
