Renewable Energy
What 8CG Has Done In LLW
8CG have spent their time in LLW working on the
different ways that we could make energy for the
school, because we already use solar energy
We researched these methods:
Geothermal
Hydro Electric
Biowaste
Electric Bikes
Kinetic Energy
Energy Costs of The School
We wrote a letter to the bursar asking how much
the energy costs of the school were. She replied
with these figures:
Gas - £32,083.73
Electric-£88,316.14
Per Year
Geothermal Energy
How Geothermal Energy Works
The Advantages of
Geothermal Energy
Geothermal energy is very efficient and wastes almost none
of the energy produced. This will help keep heating costs of
the school low during winter.
It's very
efficient!
The Disadvantages of
Geothermal Energy
Although this type of energy saves money, the initial
installation is expensive. Another disadvantage is the
generator may release harmful gases.
How Geothermal Energy
can affect Running Costs
Geothermal
Energy requires
no fuel, only a
pump is required.
The cost of
drilling however
is expensive.
Where it Would be placed
The generator
would in the
grass area behind
the tennis courts
as this is not
being used for
anything else.

Hydro Electric
Energy
The design:
Info
This massive energy producer has a giant rain gauge
which gathers water until it has been filled to its
maximum capacity.
After a button is pushed, a door under the water opens,
releasing the water onto the wheel which will turn with
the force of the water, creating energy. There is a pipe
under the wheel which is where the water will go after
flowing through it. The force of the piston pushes the
water through the rubber tubes around and back up
through another pipe dumping all the water back onto
the wheel. Therefore, creating an energy circuit.
At night-time at the end of every week, the emergency
gate is opened and releases the water out to the sea.
The
Benefits
1. It would be self sufficient as it only needs to be filled up with rain to start producing
energy.
2. There is plenty of rain in Northern Ireland so when we need to collect more it won’t
be a problem!
3. The rain gauge will be cost effective to build, as it is made from rubber, glass and
plastic.
4. Thanks to the rubber tubing the water can travel in a circuit and supply constant
energy.
5. It uses a renewable source so once built does not need any more money spent on it
The Disadvantages:
( unless damage occurs to the rubber tubing or rain gauge)
1. It could be blocked by snow or hail
stones
2. It will be less effective during
Summer as there would a decreased
The Energy and Money Saved
The price the school is currently paying for gas and electricity:
£32083.73-Gas
£88316.14-Electricity
This device should produce an average of around 0.7 kwh.
which means that it generates 6131.9 kilowatts per a year.
The cost of this is about one-third the cost of using fossil fuel or nuclear
energy and one-sixth the cost of using natural gas, saving the school
about £10,694.57 for gas and £29,438.71 for electricity.

Bio-Waste .
By Jack, Johnny, Adam, Ben and Theo.
What is Bio-Waste Energy?
Bio-Waste energy is waste that comes out of your body and
waste food formed into energy. It is useful as many people
go to the toilet in school so often it will provide energy for
the school just by taking the energy from your Body waste.
It goes through a series of tubes to get to a plant which will
turn the waste into energy.
How it gets to the plant.
The body waste is transported through a pipe to the plant
and is held from the liquid and is sent to be incinerated. A
ton of bio waste is approximately £51.
The plant
The plant burns the
waste and generates
energy. We save
about £50 every
month using
bio-waste.
19.87p per kWh
How we will use it!
We will use it as a backup power source for
when the electric goes off.The energy created
will be stored until it is needed.
Other uses for Bio-waste
Bio-waste will reduce…
the school's carbon footprint
waste in landfills
fossil fuel energy
It will produce...
organic fertiliser to farms
cost saving for customers
There is even a bus in London that runs on bio-waste
Electricity Generating
Bicycle
How much electricity can we save?
How much money will it cost?
It will cost approximately £700 pounds per
bike.
We need 30 bikes to effectively produce
electricity. 30*700=£21,000
How much electricity will be made?
The bikes cost £700 each and we want 30 which will cost
£21,000 and the will pay for themselves in the first year
with a total profit of £9,000.
One bike generates 100 Watts an hour.
100*5=500
500*5=2,500
2500*30=75,000 Watts per week from all 30 bikes put
together.
That means in a school year we would generate 3,000,000
Watts (3000 kW).
This amount of electricity is worth approximately £30,000.
We created a short timetable to express
what form class and year cycles to make
electricity. it will be a period to cycle to
create electricity to power the school. It can
be found on the next slide

How playing sports can produce
energy.
Kinetic Tiles
There is a school in Kent called Simon
Langton. This School is floored with kinetic
tiles.The students are encouraged to run and
jump in the corridors, as this produces energy.
Where are they used?
The tiles have been used
underneath a football pitch in
Rio de Janeiro.
How much energy does a kinetic tile
produce?
Kinetic tiles produce,
● enough to be able to power 4 floodlights,
● in a year, 12m of tiles can fully charge 853
mobile phones,
● one hockey pitch floored with kinetic tiles
can produce 107520 watts of electricity per
year, this is hopefully enough to power the
school.
Even a football can generate
energy
● The football only weighs 17 ounces,
● It produces energy when it is kicked.
How much energy does the football
produce?
The football produces,
● enough energy to power an LED for three
hours from a 30 minute game, this is 1 hour
of led light for a ten minute game, or one
hour of playing to six hours of electricity.
Bangor Grammar
Bangor Grammar should put kinetic tiles
underneath the hockey pitch it would cost
£6,160,000. After 51 years the school would
save a massive amount of money.
