Renewable / Carbon neutral / used to power small stations
3 of 14
Nuclear Power - Process
Fueled by uranium / nucleus breaks down into 2 / causes chain reaction producing a lot of energy / Heats a coolant which heats water for a steam generator
4 of 14
Nuclear Power - Properties
Vast amounts of energy / no carbon dioxide produced / makes radioactive waste
5 of 14
Wind Power -
Force of wind turns turbines / This turns generator / More wind = more power / Inconsistent
6 of 14
Wave Power -
Floating wave generator used over waves / This turns a generator up and down / need to withstand forms / inconsistent
7 of 14
Hydroelectric Power -
Rainwater collected in reservoir and flows downhill / This water flow turns generators
8 of 14
Tidal Power -
Water trapped behind a large barrage / water is released which turns turbines turning generators
9 of 14
Solar Power -
Solar cells used to harness suns energy / Expensive to buy - cost nothing to run / can be used for small local energy needs / many are needed / can be used to heat water
10 of 14
Geothermal Energy -
Uses energy from radioactive sources underground / uses heat energy from underground to heat water into steam / Steam used to turn generators
11 of 14
Fossil Fuels - Issues
Produce greenhouse gases causing global warming / Produce sulfur dioxide causing acid rain / non-renewable
12 of 14
Nuclear Fuels - Issues
Produce large amounts of radioactive waste / possibility or reactor exploding scattering radioactive waste
13 of 14
Renewable Sources - Issues
Cannot meat high demand / wind turbines - irritable noise / tidal barrages affect wildlife / solar cells need a lot of space / not always available or consistent
