Advantages of Wind: Good for remote communities in rural areas, Land underneath these can still be used, This already powers 9% of the UK's need in 2017, 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: Around 20% of global energy is already met by this type of energy, 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, Very low operating cost, and very reliable where it is possible to have this. , Disadvantages of Geothermal : Produces an awful smell and noise pollution, Construction causes damage to the landscape around it, Can only be installed in areas that have volcanic activity nearby,
