Energy efficiency is a measure of energy used for delivering a given service. Improving energy efficiency means getting more from the energy that we use.DECC - Energy Efficiency Strategy: 'The Energy Efficiency Opportunity in the UK'
Could this be the UK's new energy resource..?
Now here’s an interesting article for you. It was reported in the news today that a bus-sized fat ball — or 'fatberg' — has been removed from the sewers in Kingston-upon-Thames.
Weighing in at 15 tonnes, it's thought to be the biggest 'fatberg' encountered in British history.
Well, the answer is that — at 38 joules per gram (10.6 kilowatt-hours per kilogram) — the 15-tonne 'fatberg' would contain 159 megawatt-hours (MWh) of energy (assuming it's all vegetable fats).
So, what does this mean in practical terms?
In equivalent fuel terms, 159 MWh is:
- 15,437 litres of Kerosene
- 14,722 litres of Gas Oil/diesel
- 35 tonnes of wood pellets
- 42 tonnes of straw
We could keep our office warm for nearly two years on this amount of energy. The article doesn’t say how they disposed of the fat ball but to my mind this is an untapped energy resource being washed down the drain.
Who needs fracking?!
