Generating
Electricity
- Fossil Fuels
- Fossil fuels are formed when
animals and plants died millions of
years ago and the biomass was
compressed underground
- These eventually form
Natural Gas, Coal and
Crude Oil
- These eventually form
Natural Gas, Coal and
Crude Oil
- Gas Turbine
- CCGT (Combined Cycle Gas Turbine) Power
stations work by using any remaining
waste gases to heat water into steam and
turn a turbine. This is more efficient than
normal Gas turbine power stations.
- These work by burning
natural gas and the hot
waste gases spin a
turbine

- Steam Turbine
- To get electricity from fossil
fuels, you burn them. Using the
heat they produce you boil water
into steam (not just kettle steam
but a high pressured monster)
that quickly spins a turbine. This
turns a Generator and generates
electricity.

- Coal isn't as
productive when it's
in lumps and so at
some power stations
they grind it into
coal dust, which is
more efficient.
- Environmental Problems
- All fossil fuels produce
Carbon dioxide. This is
harmful because it
contributes to global
warming.
- We try and stop
it by capturing
and storing it so
it doesn't get
released into the
atmosphere.

- Acid rain
- When coal is burnt it can
produce sulphur dioxide,
which can cause acid rain
- To stop this we can remove
from the waste gases as well
as remove it from the coal
before it has been burnt
- To stop this we can remove
from the waste gases as well
as remove it from the coal
before it has been burnt
- Coal can also produce
Nitrogen oxides when
burnt, which also causes
sulphur dioxide
- To decrease the amount
released we can use
furnaces that reduce the
amount produced
- To decrease the amount
released we can use
furnaces that reduce the
amount produced
- When coal is burnt it can
produce sulphur dioxide,
which can cause acid rain
- When burning coal, smoke and
dust is produced which is harmful
to peoples health if inhaled
- We can remove it from
waste gases to stop it from
escaping into the air

years ago and the biomass was

- Alternative Fuels
- Nuclear
- Nuclear Fission heats water which
turns a turbine which, in turn,
turns a generator which generates electricity
- It uses Uranium or Plutonium as fuel
however you don't burn it to release the
energy. Instead the atoms split up in
reactions called nuclear fission
- This doesn't release any toxic fumes
and the fuel lasts for a very long time,
although it will run out someday.
- However highly dangerous
radioactive nuclear waste is
created which have to be
encased in concrete and left
for a very long time.

- Biofuels
- Biofuels are made up of biological material
made of recently dead things. These include
plant material including wood as well as
animal waste
- They are burnt like fossil fuels however differ from
them as fossil fuels have been compressed over
millions of years whereas biofuels have just grown.
- Most biofuels attempt to be carbon
neutral. This is when the amount of
Carbon dioxide released is the same as
the plant took in (when t'was alive) Most
biofuels would be carbon neutral
however transporting and growing
(tractors etc.) the biofuel releases
Carbon dioxide into the air

- Solar Cells
- Solar Panels differ from Solar
Cells as they use the Sun's energy
to heat water not provide
electricity. These are useful
however they don't provide heat
at night.
- These convert
light energy
into electrical
energy
- Useful as they can go on
rooftops etc. but are expensive
and don't work at night so could
not replace fossil fuels.

- Wind
- These use the wind
to turn a wind
turbine which turns a
generator housed at
the top of the wind
turbine structure
- This method
only works well
when there is a
strong wind
and doesn't
work at all
when there
isn't wind
- These use the wind
to turn a wind
turbine which turns a
generator housed at
the top of the wind
turbine structure
- Geothermal
- Pipes are drilled into the ground, in
volcanic areas, which allow for steam
trapped underground to rise to the
surface and turn turbines which turn
generators.
- The hot water can also be
used to heat nearby homes
however they have to be
quite close to the site.

- Water
- Tidal
- These are used in river estuaries and
build a wall with turbines fitted along it.
When the tide goes in or out, the turbines
move accordingly.

- Wave
- These use the up and
down motion of the waves
to generate electricity thus
only working well when
there are big waves

- Dams built below
reservoirs that lets
water flow through
water turbines and
turn a generator
