Transcript KS4 sustainable energy - The Co

As quickly as you can, identify what energy
source is in the photo, decide if it’s renewable
or non-renewable and note it in your book.
Wind farms for energy
The Co-operative Farms –
committed to green energy.

In 2005, The Co-operative built an
eight-turbine wind farm at Coldham in
Cambridgeshire.

It can provide enough power to supply
around 9,000 homes each year.

Each turbine costs around £2 million.
Should you invest in more wind farms or
invest in another energy resource?

Analyse the data
 The power output of one of
the Coldham wind turbines
was measured at different
wind speeds.
 Draw a suitable chart to
display the data.
 What does it show?
The turbine reaches its
maximum power output of 2
MW at a wind speed of 14 m/s
An increase of wind
speed above 14 m/s
will not increase the
power.
The turbine starts
generating electricity at a
wind speed of around 4m/s

Tidal
Motion of tides used
to turn turbines.
Wave
Motion of waves used
to generate electricity.
Solar
Light energy from the sun
can be converted directly
into electricity.
Hydroelectricity
Falling water

Your final task!
 Working on your own, write a paragraph
saying why your group’s choice of renewable
energy is a good option for the UK.
