Q

Describe solar energy and what it does/ how it works

A
  • it comes from the sun
  • the heat and light turns into electrical energy by solar cells
  • it’s free, no waste/pollution, renewable
  • doesn’t work at night, expensive to buy, in less sunny places won’t work

Q

Describe wind energy and what it does/ how it works

A
  • energy comes from the wind
  • the sun heats the atmosphere and leaves patches that are warmer, these rise and air blows to replace gaps, causing wind which turns a generator.
  • wind is free, renewable, no waste: pollution
  • isn’t always predictable, expensive, interfere tv connections, noisy, kill wildlife

Q

Describe biomass energy and what it does/ how it works

A
  • from organic materials being burnt.
  • biomass plant burns materials (eg wood) creating energy.
  • renewable, good use of waste materials, cheap.
  • collecting/ growing fuel can be difficult in large quantities, not available all year round?

Q

Describe geothermal energy and what it does/ how it works

A
  • from within the earth, near heated places.
  • power plants tap into hot reservoirs underground, renewable heat is used to drive an electrical generator.
  • no pollution, doesn’t contribute to greenhouse gases, no fuel is needed and power stations are small.
  • not many suitable places to build them.

Q

Describe hydroelectric energy and what it does/ how it works

A
  • from running water
  • Dan is needed, water files through tunnels and turns turbines that drive generators to produce electricity.
  • once built energy is free, no waste/pollution, can be constantly generated.
  • building Dan will flood upstream, damage wildlife and could cause obstruction to public

Q

Describe tidal energy and what it does/ how it works

A
  • from the earths ocean movement.
  • tidal Barriers leaves little space for water to get through which turns a turbine creating energy.
  • once built is free, no pollution/ waste, tides are predictable, not expensive to maintain.
  • few suitable locations, only provide energy 10 hours a day

Q

Describe wave energy and what it does/ how it works

A
  • from waves being blown across the sea.
  • works like swimming pool wave machine.
  • energy is free, no pollution, not expensive to maintain, produces lots of energy.
  • must withstand all weather, must be suitable site and can produce wide range of energy due to different waves.
