Why might our electricity become more
expensive in the the next couple of
months?
Renewable resources;
By the end of the lesson you will;
Be able to describe and explain the key features of tidal
energy
2) Have evaluated which method would be best for the UK
and a range of countries around the world
3) Have explained smaller scale alternatives to be used in
the the home

Homework
You need to research 3 different
methods of producing renewable
energies in the UK.
You should explain;
1) Where are they based?
2) How successful have they
been?
3) What issues have there
been?
4) Are they a long term solution

Wave Energy
Task
1. Watch the following animation
2. Describe how wave energy is generated
Where is it best
suited for?
What is it?
How does it
generate electricity?
Why is it not a
good method?
Why is it a good method?

Renewable energy relative costs;
Task
Read through the following article
1. Which are the cheapest of the Stock fuels?
2. Which are the cheapest of the flow fuels?
3. How much different is there in the costs of stock and flow energies?
4. Why have these changes occurred?
1. The levelized cost of electricity (LCOE) from wind and solar sources in America has fallen
by more than 50% over the past four years
2. Lazard estimates that utility-scale solar PV is now a competitive source of peak energy
compared to fossil fuel power in many parts of the world without subsidies
3. solar PV and wind energy both fall within the range of $68-$104 per MWh, making them
extremely [coal ($65-$145 per MWh), nuclear ($86-$122 per MWh), and integrated
gasification combined cycle ($95-$154 per MWh).]
4. With US government subsidies the energy is even cheaper. wind ($23-$85 per MWh) and
thin-film utility scale solar PV ($51-$78 per MWh) especially competitive.
5. utility-scale solar PV leads the LCOE charge, rooftop solar PV remains expensive by
comparison
