What is Green energy?
Green energy is clean and renewable energy all have in common is that they're being increasingly used to generate electricity in order to phase out the use of fossil fuels, like coal and gas, which are a key cause of climate change.
Type of Green enegy
The main sources are wind energy, solar power and hydroelectric power (including tidal energy, which uses ocean energy from the tides in the sea). 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 six form are 1. solar power This common type of renewable energy is usually produced using photovoltaic cells that capture sunlight and turn it into electricity 2.wind power 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 3.Hydro power Also known as hydroelectric power, this type of green energy uses the flow of water in rivers, streams, dams or elsewhere to produce electricity 4.Geothermal energy This type of green power uses thermal energy that has been stored just under the earth’s crust 5.Biomass This renewable resource also needs to be carefully managed in order to be truly labelled as a ‘green energy’ sourceand 6.Biofuel Rather than burning biomass as mentioned above, these organic materials can be transformed into fuel such as ethanol and biodiesel
How does it work?
As a source of energy, green energy often comes from renewable energy technologies such as solar energy, wind power, geothermal energy, biomass and hydroelectric power. 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.
Example
There are plenty of examples of green energy in use today, from energy production through to thermal heating for buildings, off-highway and transport. Many industries are investigating green solutions ex heating cooling in building or transport system.
Green energy solutions are being used for buildings ranging from large office blocks to people’s homes. These include solar water heaters, biomass fuelled boilers and direct heat from geothermal, as well as cooling systems powered by renewable sources.
Renewable heat for industrial processes can be run using biomass or renewable electricity. Hydrogen is now a large provider of renewable energy for the cement, iron, steel and chemical industries.
Sustainable biofuels and renewable electricity are growing in use for transportation across multiple industry sectors. Automotive is an obvious example as electrification advances to replace fossil fuels, but aerospace and construction are other areas that are actively investigating electrification.
