To go back to anaerobic digestors, the extent to which they will take up the load on the national grid is very small. A former colleague of ours was involved in that for years and he gave up on it. It is a help, but it is a minor one. Nuclear, wave, tidal and biomass energy are also in their infancy in so far as research is concerned. I have been hearing about them for the last 25 years and I have still not seen them.
