- 1Renewable energyEnergy source that quickly replenishes themselves.
Can be used again and again.
Called infinite energy sources - 2Non-renewable energyEnergy that cannot be reused again.
Finite life span.
Usually in the form of fossil fuels.
Take a long time to replenish - 3Renewable energy sourcesHydroelectric power
Tidal
Solar
Wind
Geothermal
Biomass - 4Nonrenewable energy sourcesOil
Gas
Petrol
Diesel - 5How we get oil (Non-renewable)Pumped from the ground as crude oil.
Then put in a fractional distillation column where it is separated from all the other hydrocarbons - 6Pros of oilProduce a constant energy supply until it runs out
- 7Cons of oilRuns out
Produces toxic and harmful gases - 8How we get natural gas (Non-renawable)Comes from plankton
Formed by plants that grew in tropical swamps.
Accumulates in porous rocks - 9Pros of natural gasLess expensive them oil
Less expensive to set up
Constant energy supply - 10Cons of natural gasRuns out
Produces toxic and harmful gases - 11How we get coal (Non-renewable)Sedimentary rocks formed from trees growing in tropical swamp forests
- 12Pros of coalMore coal available than any other nonrenewables
cheeper
overall cost is cheep - 13Cons of coalRuns out
Produces toxic and harmful gases - 14Geothermal energy (Renewable)The heat from rocks or water beneath the earth surface.
Steam is used to spin a turbine and produce energy - 15Pros of Geothermal energyDoesn't produce pollution
Cheap running cost
Doesn't run out with use - 16Cons of GeothermalDifficult to find a site
Can run out of steam when drilling
Dangerous gases can come out when drilling - 17Wind Energy (Renewable)Wind drives large blades which turns a turbine creating electricity
- 18Pros of Wind energyCan be tourist attractions
Can work on land or at sea
Low running cost
No waste pollution - 19Cons of Wind energyLow level noise
Interference with phones and radars
spoil the view
No wind= No power - 20Solar energy (Renewable)Harnessing large amounts of energy given out by the sun by trapping the suns rays which is then converted into electricity
- 21Pros of Solar energyLow cost to run
Can produce energy in remote locations
No waste and pollution - 22Cons of Solar energyPhotovoltaic cells can be expensive
Doesn't work at night - 23Biomass energy (Renewable)A fuel that comes from biomass
includes bioethanol and alcohol which is made by fermenting sugar in plants
Biodiesels- vegetable oils
Biogas- Methane produced by the break down of organic materials by bacteria - 24Pros of Biomass energyFuel is cheap
Waste materials make energy - 25Cons of Biomass energyCollecting enough waste can be difficult
Creates Carbon Dioxide - 26Hydroelectric power (Renewable)Water stored in dams and flowing rivers create energy
The water released from dams spins turbines which generates electricity, the same goes for flowing rivers - 27Pros of Hydroelectric powerConstant work
Power output can be increased quickly
Once built cheap to run
No waste or pollution
Reliable
Water can be stored behind the dam until needed - 28Cons of Hydroelectric powerExpensive to built
May cause flooding else where
Suitable sited are limited
pressure of water on land = eathquakes - 29Pros of Nuclear powerCheap electricity
Available
Works when needed
Reduces CO2 emissions
Produces a lot of power from little input - 30Cons of Nuclear powerNuclear waste and pollution
Accidents and disasters can happen
Technology quickly becomes out of date
Nuclear weapons are created and used - 31Fuel woodWood is harvested for fuel
- 32Pros of Fuel woodAvailable
Cheap to harvest
Kind of environmentally friendly
Sustainable - 33Cons of Fuel woodInconvenience
Doesn't lower Carbon emissions
Releases unburnt carbon - 34Main energy sources in LEDCsCoal
Hydroelectric power
Oil - 35Main energy source in NICsCoal
Gas
Oil - 36Main energy sources in MEDCsCoal
