Renewable Energy: Green power to the people
Renewable energy sources are those that use natural resources such as sunlight, wind, tides or geothermal heat. They are naturally replenished and the generation of energy from these sources releases little or no greenhouse gas. Unfortunately, only five per cent of the energy used by Australians comes from these power options.
Solar—Energy from the Sun
Solar energy is the sun’s rays (solar radiation) that reach the earth. This energy can be transformed into heat in solar water heaters or solar thermal power plants or into electricity using photovoltaic cells.
Wind—Energy from moving air
Wind can be used to generate electricity using wind turbines, much like old-fashioned windmills. The wind turns the blades on the turbine to power a generator. The generator produces electricity which can be fed into batteries for an individual house or directly into the grid in the case of a wind farm.
Hydropower—Energy from moving water
Moving water can be harnessed to provide electricity. This is called hydropower or hydroelectric power. Moving water from dams or rivers drives turbines to generate electricity. Tidal and wave power use the movements in the ocean to drive turbines.
Geothermal—Energy from the earth’s core
The earth's core is extremely hot. This heat provides an enormous source of energy called geothermal energy. Geothermal energy can be used to produce steam to drive turbines.
