1
clean can be seen …there’s wind power… which is and on hillsides
fairly predictable and can be seen on hillsides all around Wales
2
…solar panels or “photovoltaic cells”…
can turn Sunlight directly into electricity
3
…like this massive 11 MegaWatt solar power station…
Near Serpa in Portugal comprising Fifty two thousand solar panels …around which sheep graze and frolic happily…
4
rooftop …and we can use it to heat water too…. system being used on a
Like this system being used on a rooftop in Israel
5
to produce electricity
…like the PS10 “solar power tower” in Seville in Spain… which boils water to make steam …and uses the steam to turn turbines and generators to produce electricity
6
could be used …or energy from water… estuary lots of electricity
like the Severn estuary which could be used To generate lots of electricity
7
…by holding the water behind a big “barrage”
when the tide is high…
8
…so the water that flows through…
9
…and gets trapped behind the barrage…
10
…and when the tide goes back down…
…we let all the water out... making lots of electricity…!
11
…we can use crops for fuels – we call these biofuels….
Lots of cars now use vegetable oil for fuel
12
…we also have nuclear power…
which doesn’t release harmful gases into the atmosphere
13
Radioactive problems… does produce waste harmful Although it Which can
cause other problems…
14
…we can get power from coal or oil fired power stations………..
Burning coal releases harmful gases into the atmosphere
15
steam which spins turbines which heat energy Fuels are burned
to release heat energy which boils Water to produce steam which spins turbines which turn generators!
16
…and from wood fired power stations
Which releases LESS harmful gases than coal
17
…some of this power can be produced by hydroelectricity
18
By power stations like this one…
…at Ffestiniog
