What substances are used to generate electricity?
Water, wind, fossil fuels, biofuels, nuclear fuels -
Describe how a power station works
Fuel is burnt in a furnace. This heat turns the water into steam. The steam turns a turbine which, in turn, turns a generator which generates the electricity. The steam is then sent to cooling towers where it is condensed into water and the process repeats. -
What is the difference between normal power stations and regular power stations?
Nuclear power stations use nuclear fission to generate energy -
What is tidal power?
When the tide goes in/out it turns turbines -
What is wave power?
The motion of waves forces air through a tube/waves pass underneath -
What is wind power?
Wind turns turbines which turn generators -
What is solar power (cells and towers)?
Cells turn sunlight into electricity, towers use convection currents to turn turbines -
What is geothermal power?
Hot steam from deep underground is used to turn turbines -
Give advantages and disadvantages of wind power
+ Renewable, no harmful gases
- Noisy, visual pollution, depends on wind -
Give advantages and disadvantages of water power
+ Renewable, no fuel costs, no harmful gases, reliable
- Wave can't produce large amounts of electricity, tidal destroys habitats, hydro floods farmland, expensive
- Higher grades + faster learning
