P1
Energy sources
Wind power
- No pollution
- No fuel costs
- Annoying noise
- Cannot be increased
with extra demand
Geothermal
- Little damage to
environment
- Reliable source of free
energy
- Remote
- High cost
HEP
- Flow of water can
be controlled
- No fuel costs
- Look unslighlty and dry up
- Loss of habitat
Wave power
- No pollution
- No fuel costs
- DIfficult and expensive
to maintain
- Disturb habitats
Tidal barrages
- Happens twice a day
- No fuel costs
- Height of tide is variable
- Remote
Solar cells
- No environmental
damage
- Cost effective
- Only work during the
day
- cannot be increased with
extra demand
Bio mass
- Fairly reliable
- Continously stored and produced
- Burning produces CO2 and methane
- Destroy natural habitats
-
Thermal insulation
-
Cavity walls
Inner and outer wall with
air gap in middle, reducing energy transfer
-
