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
