Physics - energy resources

List renewable resources
Wind, solar, hydroelectric, wave, tidal, biofules, geothermal
1 of 11
List some advantages of renewable energy
Will never run out, don't release CO2 (don't contribute to climate change)
2 of 11
A disadvantage could be that some are not ___ (e.g wind/solar)
Reliable
3 of 11
Why aren't they reliable?
won't always be lots of wind and sun to generate electricity (efficient electricity)
4 of 11
___ power destroys habitats when damns are built and valleys flood
Hydroelectric
5 of 11
List another disadvantage for hydroelectricity
Only useful if in place with lots of rivers (not suitable for UK)
6 of 11
Geothermal energy uses __ from earth to generate electricity
Heat
7 of 11
What are biofuels produced from?
Plant material
8 of 11
Burning the fuel releases CO2 but no extra CO2 is released into air. Why?
Grow of plants took in CO2 so it's carbon neutral
9 of 11
Can biofules be used to power any vehicles?
Yes
10 of 11
One problem is that if we use land to grow crops for biofuel, it could...
Increase food prices
