These are the words of Alex Salmond. An analogy of this sort has already been made in an Energy Voice headline and reported on here at:
A new report from Energy Voice today uses figures from Associate Professor Thomas Adcock of Oxford University to illustrate the enormous power available to Scotland in only one, admittedly the most powerful one, tidal channel. You can see a fuller and impressive account of the wave power potential around Scotland’s more than 16 000 miles of mostly turbulent coastline in this:
Here are Addison’s figures on the Pentland Firth:
- Tidal surge speeds of more than 16ft per second! Imagine that if you can.
- Potentially 1.9 gigawatts-hours (GWh) – Torness and Sizewell B do at best around 1.2 gigawatts. The other nuclear plants do far less. A gigawatt is a billion watts or a million electric fires.
- Around 16.5 terrawatt-hours (TWh). One terawatt hour is equal to a sustained power of approximately 114 megawatts for a period of one year or, from one source, enough to meet around half of Scotland’s power demand.
Add the last figure to the 14.9 TWh already being produced by renewables-based energy sources and Scotland could hit its 100% target by 2020 and not 2030 as planned.
Hinckley Point C is expected to produce 3.2 gigawatt-hours for the south of England but at what cost financially and ecologically? The latter cost could be, of course, unmeasurable but the plant alone is now estimated to cost £19.6 billion to build and the electricity generated looks like costing at £92.50 per MWh, twice that of the latest wind power estimates of £57.50 per MWh and falling as bigger turbines come on stream.
