P3.2 Energy from wind and water Flashcards
How is wind power generated?
Force of the wind drives the turbine’s blade around - this turns a generator
Power generated increases as the wind speed increases - however unreliable because when there is little or no wind they do not generate any electricity
How is wave power generated ?
The motion caused by the waves turns the generator so it generates electricity - a cable between generator and the shoreline deliver electricity to the grid system
How is hydroelectric power generated?
When rainwater that is collected in a reservoir flows downhill - flowing water drives turbine that turns an electricity generator
How is tidal power generated ?
Traps water from each high tide behind a barrage - high tide can then be released into the sea through turbines - which drives generators in the barrage
