Physics 1.3
wind power (turbines)
many in exposed places
contains a generator
no pollution (except manufacture)
spoil views
cover large areas of land
1500 turbines = 1 coal powered power station
very noisy
weather dependant
cannot increase supply on demand
high manufacture costs
low running costs
no fuel required
solar
solar cells used in watches and calculators
used in remote places
used on road signs and satellites
no pollution (except manufacture)
reliable in hot sunny places
cant increase supply on demand
costs nothing to run
used on a relatively small scale
geothermal
based on location
found in volcanic areas
reliable
little eco damage
heat buildings
produce electricity
Energy resources
non - renewable
