how do we reduce our short-term future electricity demand (and/or increase supply) without increasing fossil fuel consumption?

This is the big question for the whole world not just the UK. Another question is ... how do we continue to grow our economies with rapidly declining fossil fuel consumption?

After reading the IPCC conclusions on Dangerous Antropogenic Climate Change the world's politicians have decided that CO2 emissions MUST fall to 80% of the 1990 levels by 2050 - however this assumes that the levels of CO2 start falling steadily from NOW.

If the 80% decline is to be met by 2050 then by 2020 we need to have reduced emissions by 30% or so - if we delay the decline then the deadline is not 2050 but some much sooner time - especially if we continue to actually increase emissions in the short term, or if the politicians are too optimistic with their 'best guess' as to what is safe.

So, what is the UK (and the world) to do? ... it looks like the UK can easily meet the 30% targets just by avoiding imports of coal, oil and gas ... a large number of new nukes may be out of the question as well, since they put a lot of CO2 into the air during the construction phase (just at the time we will be struggling to reduce the emissions).

It doesn't look like the UK has a coherent, adequate, timely plan 'A' let alone plan 'B' and we actually have oil, gas, and some coal - unlike most other European countries!

Does that mean we will get dangerous climate change because growth will be more important than climate change? ... if so forget about the nukes! ... we will need the money and declining energy earmarked for them to rebuild all our major coastal cities on higher ground.
