Replacing Natural Gas
By Paul Homewood
John Fuller asked me what effect it would have if natural gas was replaced by electricity.
We can start by looking at DECC’s numbers for gas consumption last year. Note that these are in GWh.
Excluding electricity generation, we are looking at 580 TWh.
Total electricity generation last year was 339 TWh, we would virtually have to treble this figure to replace natural gas.
It does not end there, because demand for gas, domestic at least, is concentrated during winter months. The respective figures for Q1 last year were electricity generation of 96 TWh, and gas consumption (excl generation) of 226 TWh.
Thus in winter we would need to increase electricity generation by 235%.
Worse still, since gas demand is heaviest in early mornings and evenings in winter, peak loading would make matters even worse. (I did publish a graph on this a few weeks ago, but annoyingly I can’t find it!!)
Not only would we need to find the generating capacity to cope with all of this, but we would also need to drastically ramp up transmission capabilities.
