My mum is one of our country's energy experts. She's a sceptic about global warming and deeply embarrassed by my Green Party membership, so when she says we are in the s**t we should listen.
We have reached 'peak oil'. That is, our use is exceeding supply. In thirty yrs (less if China keeps on growing as it is) the oil runs out. This not lonly means no more SUVs and cheap weekends in Prague, but no fridges, freezers, hospital equipment...no electricity in fact. It will also probably mean war (viz. Iraq already happening). Our kids will be about our ages now - we will probably have grandkids too.
Only a a radical rethink can stop this situation.
