Non-Renewable Energy Resources
Finite resources that once used can't be replaced, such as coal, oil and natural gas, nuclear energy, fuelwood etc.
Renewable (Alternative) Resoures
Sustainable resources that can be used over and over again such as Hydro-electric power, Geothermal, Wind, Solar, Hydrogen, tidal, waves and biomass etc.
Generates the highest proportion of renewable type of energy.
Only made on river, e.g. three gorges dam in china on the Yangtze.
Works by a dam being created, with a reservoir on one side and falls on the other. Water is released from the reservoir and follws into the falls, in the process turning turbines which then creates electricity.
Means heat from the earth, works by pumping clod water into the earth through boleholes and then returns to the surface as steam or geysers and the harnessed and turned into electricity.
Good renewable energy, which creates no pollution. Disadvantages are that it is high cost maintain and construct, limited at volcanic areas (e.g. New Zealand, Wairakei and Rotorua) and threat to power station area that volcanic eruptions and earthquake can from sulphuric gas emission.
Used by several industrialed countries such as france, belgium, taiwan, korea. Strong emotion as the merits and consequences of nuclear power, e.g. radiation hazards if miss used.
Very traditional way of making energy. Still used by western countries such as USA ,South Africa and Australia. Criticised due to fumes emitted. Reserves luckly to run out in the next 300 years.
