In the run-up to the UN Kyoto climate change conference, energy lobbying is at its height. Legislation for the long term support of renewables is on hold, pending a decision on the global introduction of green house gas emission limits. The nuclear option is being sold as the only dependable and large scale fuel source, free of any emissions. The costs, however, tend to be glossed over. The American coal lobby argues that increased use of electricity will reduce carbon dioxide emissions, as modern power stations are more efficient than many industrial processes. The clean coal lobby is pushing for more R&D, though advanced cycles, at least five years away, only reduce emissions by around 25%. The gas lobby, if there is one, is less conspicuous; but with gas in plentiful, cheap supply, releasing modest emissions, lobbying is hardly necessary.
