Advantages of Wind: Good for remote communities in rural areas, Land underneath these can still be used, Disadvantages of Wind: Very noisy as the turbines spin, If there is no wind, there is no energy! , The cost of the system depends on the size of the turbine, and can be up to £34,000 to install just one. , Advantages of Hydroelectricity: Can be used at a range of scales (small or large), Disadvantages of Hydroelectricity: Very expensive to build in the mountains, Often requires large areas of land as the area behind needs to be flooded, The area needs to be high enough to generate enough Gravitational Potential Energy, China's Three Gorges Dam displaced at least 1.2 million people from 13 cities when the reservoir was created! , Advantages of Geothermal: This does not emit greenhouse gases at all, as everything is kept in pipes, Disadvantages of Geothermal : Construction causes damage to the landscape around it, Can only be installed in areas that have volcanic activity nearby, Advantages of non renewables: Reliable sources of energy, Lots of energy released per kilogram of fuel, Easily available for all domestic activities, Found in abundance all over the world , Disadvantages of non renewables: Release pollutants/radioactive waste, They are finite, By products are not biodegradable and sit in landfills, Their extraction damages the earth,
