- Renewable/ Non-renewable energy
- Non Renewable
- Coal – Formed from fossilised plants
- Advantages
- Cheap to mine
- Easy to convert to energy
- Should last for 250 years
- Disadvantages
- When burnt releases CO2 which adds to global warming
- Advantages
- Oil – Formed from fossilised animals
- Advantages
- Cheap to mine
- Easy to convert to energy
- Should last for 50 years
- Disadvantages
- When burnt releases CO2 which adds to global warming
- Advantages
- Nuclear – Produced from Uranium from mining
- Advantages
- Small amount of uranium which results in a lot of energy
- Raw materials will last a long time
- No greenhouse gases produced
- Disadvantages
- Nuclear reactors are expensive to build and run
- Nuclear waste is radioactive and toxic. It is stored for many years which is expensive. If there is a leak it is very dangerous
- Advantages
- Natural Gas – Formed from fossilised animals
- Advantages
- Cheap to mine
- Easy to convert to energy
- Should last for 70 years
- Cleaner than oil
- Disadvantages
- When burnt releases CO2 which adds to global warming
- Advantages
- Biomass – Decaying plants and animals
- Advantages
- Cheap and readily available
- If plants are regrown it is renewable
- Disadvantages
- When burnt it releases CO2
- Large crop areas removed – lead to food shortag
- Advantages
- Wood – Trees
- Advantages
- Cheap and readily available
- If trees are regrown it is renewable
- Disadvntages
- When burnt in releases CO2
- Advantages
- Coal – Formed from fossilised plants
- Renewable
- Hydro Electric Power (HEP) Power from water
- Advantages
- No greenhouse gases
- Cheap to run once built
- Produces large bodies of water for leisure
- Disadvantages
- Cause build up of sediments
- Alter the water flow which affects ecology
- Dams effect people
- Dams effect people
- Advantages
- Tidal – Uses tides for energy
- Advantages
- Never runs out
- Reliable technology
- No greenhouse gases
- Helps to prevent floods
- Disadvantages
- Only a few suitable places for it to be located
- Only a few suitable places for it to be located
- Tidal schemes are expensive to install
- Advantages
- Biofuel (aka Biomass) Energy from plants
- Advantages
- 78% less carbon dioxide
- No Sulphur = no acid rain
- Biodegradeable
- Engines last longer with it
- Saves money
- Helps Kyoto Protocol
- Just as good as diesel
- Non-toxic
- Disadvantages
- problems for birds/insects/ biodiversity
- Large land needed
- Rapeseed is bad
- Needs lots of crops (Food Shortages)
- Advantages
- Wave – Uses waves for energy
- Advantages
- Never run out
- No greenhouse gases
- No safety risks
- After being built everything is ok
- Disadvantages
- Lots of money to build
- Can effect local and environmental groups
- Advantages
- Geothermal – Heat from the Earth for energy
- Advantages
- No pollution
- Reduce reliance on fossil fuels
- Direct use
- Creates jobs for locals
- Disadvantages
- Hard to get to
- May run out of steam
- High installation cost
- May release harmful gases from inside the Earth
- Advantages
- Solar – Energy from the Sun
- Advantages
- No noise pollution
- Very little maintenance to keep running
- Easy to install
- Constantly improving
- Disadvantages
- Lots of solar cells needed
- If there is no sun, no power
- Advantages
- Hydro Electric Power (HEP) Power from water
- Non Renewable
