Transcript of … there’s wind power … which is clean fairly predictable and can be seen on hillsides all...
![Page 1: … there’s wind power … which is clean fairly predictable and can be seen on hillsides all around Wales.](https://reader036.fdocuments.us/reader036/viewer/2022062423/5697bf8d1a28abf838c8c4e4/html5/thumbnails/1.jpg)
…there’s wind power…
which
is
cleanfairly predictable
and
can be seen
on hillsides
all around Wales
![Page 2: … there’s wind power … which is clean fairly predictable and can be seen on hillsides all around Wales.](https://reader036.fdocuments.us/reader036/viewer/2022062423/5697bf8d1a28abf838c8c4e4/html5/thumbnails/2.jpg)
…solar panels or “photovoltaic cells”…
can
turn
Sunlight
directly
into
electricity
![Page 3: … there’s wind power … which is clean fairly predictable and can be seen on hillsides all around Wales.](https://reader036.fdocuments.us/reader036/viewer/2022062423/5697bf8d1a28abf838c8c4e4/html5/thumbnails/3.jpg)
…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…

…and we can use it to heat water too….
Like this
system
being
used
on a
rooftopin
Israel
![Page 5: … there’s wind power … which is clean fairly predictable and can be seen on hillsides all around Wales.](https://reader036.fdocuments.us/reader036/viewer/2022062423/5697bf8d1a28abf838c8c4e4/html5/thumbnails/5.jpg)
…like the PS10 “solar power tower” in Seville in Spain…
…and uses the steam to turn turbines and generators
to produce electricity
which
boils
water to make
steam
![Page 6: … there’s wind power … which is clean fairly predictable and can be seen on hillsides all around Wales.](https://reader036.fdocuments.us/reader036/viewer/2022062423/5697bf8d1a28abf838c8c4e4/html5/thumbnails/6.jpg)
…or energy from water…
like
the Severnestuary
which
could be used
To generate
lots of electricity
![Page 7: … there’s wind power … which is clean fairly predictable and can be seen on hillsides all around Wales.](https://reader036.fdocuments.us/reader036/viewer/2022062423/5697bf8d1a28abf838c8c4e4/html5/thumbnails/7.jpg)
…by holding the water behind a big “barrage”
when the tide is high…
![Page 8: … there’s wind power … which is clean fairly predictable and can be seen on hillsides all around Wales.](https://reader036.fdocuments.us/reader036/viewer/2022062423/5697bf8d1a28abf838c8c4e4/html5/thumbnails/8.jpg)
…so the water that flows through…
![Page 9: … there’s wind power … which is clean fairly predictable and can be seen on hillsides all around Wales.](https://reader036.fdocuments.us/reader036/viewer/2022062423/5697bf8d1a28abf838c8c4e4/html5/thumbnails/9.jpg)
…and gets trapped behind the barrage…
![Page 10: … there’s wind power … which is clean fairly predictable and can be seen on hillsides all around Wales.](https://reader036.fdocuments.us/reader036/viewer/2022062423/5697bf8d1a28abf838c8c4e4/html5/thumbnails/10.jpg)
…and when the tide goes back down…
…we let all the water out...
making lots of electricity…!
![Page 11: … there’s wind power … which is clean fairly predictable and can be seen on hillsides all around Wales.](https://reader036.fdocuments.us/reader036/viewer/2022062423/5697bf8d1a28abf838c8c4e4/html5/thumbnails/11.jpg)
…we can use crops for fuels – we call these biofuels….
Lots of cars now use
vegetable oil
for
fuel
![Page 12: … there’s wind power … which is clean fairly predictable and can be seen on hillsides all around Wales.](https://reader036.fdocuments.us/reader036/viewer/2022062423/5697bf8d1a28abf838c8c4e4/html5/thumbnails/12.jpg)
…we also have nuclear power…
which doesn’t release
harmful gases
into
the
atmosphere
![Page 13: … there’s wind power … which is clean fairly predictable and can be seen on hillsides all around Wales.](https://reader036.fdocuments.us/reader036/viewer/2022062423/5697bf8d1a28abf838c8c4e4/html5/thumbnails/13.jpg)
Although it
does produce
harmful
Radioactive
wasteWhich can
cause other
problems…
![Page 14: … there’s wind power … which is clean fairly predictable and can be seen on hillsides all around Wales.](https://reader036.fdocuments.us/reader036/viewer/2022062423/5697bf8d1a28abf838c8c4e4/html5/thumbnails/14.jpg)
…we can get power from coal or oil fired power stations………..
Burning coal
releases
harmful gases
into the
atmosphere
![Page 15: … there’s wind power … which is clean fairly predictable and can be seen on hillsides all around Wales.](https://reader036.fdocuments.us/reader036/viewer/2022062423/5697bf8d1a28abf838c8c4e4/html5/thumbnails/15.jpg)
Fuels are burned
to release
heat energy
which boils Waterto produce
steam which
spins
turbineswhich
turn generators!

…and from wood fired power stations
Which releases
LESS
harmful gases
than coal
![Page 17: … there’s wind power … which is clean fairly predictable and can be seen on hillsides all around Wales.](https://reader036.fdocuments.us/reader036/viewer/2022062423/5697bf8d1a28abf838c8c4e4/html5/thumbnails/17.jpg)
…some of this power can be
produced by hydroelectricity
![Page 18: … there’s wind power … which is clean fairly predictable and can be seen on hillsides all around Wales.](https://reader036.fdocuments.us/reader036/viewer/2022062423/5697bf8d1a28abf838c8c4e4/html5/thumbnails/18.jpg)
…at Ffestiniog
By power stations like this one…
