snip> [QUOTE] But if we are to err on the side of caution, not a bad idea per se, all it requires is the closure of all conventional coal/oil burninng power stations within 20 years. Job done. Replaced with flue gas extraction plants, nuclear, tidal and wind/wave. There is NO need at all to restrict access to vehicles or to green tax domestic use fuels.[/QUOTE] Why do you need to waste hundreds of millions of £££ on FGD if you've binned all the coal fired plants? It's only coal fired stations that need FGD and nuclear stations are crap until someone decides which part of Scotland we're dumping all the waste in.
