Revision
Bio-fuels and Non-Renewables
- Bio fuels = renewable energy = made from plants and waste = can be in any state (solid, liquid or gas)
- Can be burnt to produce electricity
- Carbon neutral
- Reliable = plants take a short amount of time to grow
- Cannot meet high energy supplies when there is a demand for energy
- Biofuels are stored for when they are needed
- Growing crops from biofuels = not enough space or water for food crops
- To make space to grow crops = deforestation = lots of species losing their habitats
- Decay and burning of vegetation = co2 and methane released
- Fossil fuels and nuclear fuels = reliable
- Enough to meet current demands = as extracted from earth at a fast rate = so, can respond quickly when there is an energy surge
- They are running out
- running costs aren’t expensive
- all fossil fuels, when burnt release CO2 = adds to greenhouse effect = contributes to global warming
- burning coal and oil = sulphur dioxide released = acid rain = harmful to trees and buildings
- acid rain can be reduced by removing sulphur from fuel before burning
- coal mining = ruins the landscape
- oil spillages = serious environmental problems
- nuclear power = clean. Nuclear waste = dangerous & difficult to dispose of
- nuclear fuel = cheap
- overall cost of nuclear power = high
- major risks for example Fukushima disaster in Japan
