![]() 3. HydropowerĪlso known as hydroelectric power, this type of green energy uses the flow of water in rivers, streams, dams or elsewhere to produce electricity. Particularly suited to offshore and higher altitude sites, wind energy uses the power of the flow of air around the world to push turbines that then generate electricity. Solar power has now become affordable enough to be used for domestic purposes including garden lighting, although it is also used on a larger scale to power entire neighbourhoods. Solar power is also used to heat buildings and for hot water as well as for cooking and lighting. This common type of renewable energy is usually produced using photovoltaic cells that capture sunlight and turn it into electricity. The six most common forms are as follows: 1. Solar Power Solar and wind power are able to be produced on a small scale at people’s homes or alternatively, they can be generated on a larger, industrial scale. The main sources are wind energy, solar power and hydroelectric power (including tidal energy, which uses ocean energy from the tides in the sea). ![]() ![]() Green sources also often avoid mining or drilling operations that can be damaging to eco-systems. Green energy sources are usually naturally replenished, as opposed to fossil fuel sources like natural gas or coal, which can take millions of years to develop. For example, power generation that burns organic material from sustainable forests may be renewable, but it is not necessarily green, due to the CO 2 produced by the burning process itself. This means that not all sources used by the renewable energy industry are green. In order to be deemed green energy, a resource cannot produce pollution, such as is found with fossil fuels. Each of these technologies works in different ways, whether that is by taking power from the sun, as with solar panels, or using wind turbines or the flow of water to generate energy.
