The only thing you can say for certain about British weather is that it’s unpredictable. One minute the sun is shining. The next, you’re soaked through by April showers. Given our eclectic weather and island status, you’d think that we’d be an ideal location for wind power. But despite leading the world in offshore wind capacity, wind contributes less than three per cent of the UK’s energy needs.
If, in any event, we could store that energy on a large scale and release it when needed, our low carbon future would look far brighter. The problem is that electrical energy can’t be stored directly at an economic rate. It first has to be transformed into another form, and doing so causes losses in efficiency. Engineers are working hard to address this problem.
