What are the three fossil fuel resources?
Oil
Coal
Gas
What are the types of non-renewable energy?
Oil
Coal
Gas
Nuclear
What are the types of renewable energy?
Bio-fuel or biomass wind wave hydroelectric tidal solar (photovoltaic) geothermal
What is the definition of a renewable resource?
A resource that can be replenished in one human lifetime (c. 70 years)
What are some main uses for energy resources?
Transport
Electricity production
Heating
What are the advantages and disadvantages of fossil fuel energy use?
Advantages: Uses existing technology; releases lots of energy; can be built anywhere.
Disadvantages: releases carbon dioxide increasing the greenhouse effect contributing to global warming and climate change; produces sulfur dioxide contributing to acid rain.
What are the advantages and disadvantages of solar energy use?
Advantages: does not produce greenhouse gases; land can be used for livestock farming simultaneously.
Disadvantages: Does not produce large amounts of energy; dependent upon climate; uses large areas of land.
What are the advantages and disadvantages of wind energy use?
Advantages: does not produce greenhouse gases; land can be used for livestock farming simultaneously; can be built out to sea where wind is more reliable
Disadvantages: Does not produce large amounts of energy; dependent upon climate; uses large areas of land; can be an eyesore.
What are the advantages and disadvantages of nuclear energy use?
Advantages: Uses existing technology; releases lots of energy; does not produce carbon dioxide.
Disadvantages: produces radioactive waste which is radioactive for a long time and so difficult to dispose of; risk of nuclear leaks and explosions so needs to be built far from population centres.
Why is there a need to move away from fossil fuel energy use?
Releases carbon dioxide increasing the greenhouse effect contributing to global warming; and leading to climate change.
