Renewable energy is energy created by sources that are not used up or depleted. Most forms of renewable energy do not produce carbon dioxide and other harmful gases. Using more renewable energy sources would reduce carbon dioxide emissions and minimise global warming.
Hydroelectric Power
Hydroelectric power (HEP) uses the force of moving water to reate electricity. However, HEP
stations often require large dams, which disrupt ecosystems and displace people. HEP is the most widely used renewable source, providing 20% of the world's energy.
Solar Power
The Sun provides the main source of energy for all living things. Solar energy is free and will never run out. We can use solar panels to turn the Sun’s energy into useful energy.
Wind Power
Wind turbines harness the movement of air to produce energy. They are often found grouped together in wind farms. Biomass This is the term used to describe plant materials and animal waste, which can be burnt for energy.
Geothermal Energy
Geothermal energy is energy that is generated by using the heat beneath the Earth’s surface.
