I think it is commendable to try and be economical in our consumption of fossil fuels. But lets not forget that it is our use of these fuels that has made our lives hugely more enjoyable, productive and long...
To go back to self-sufficiency would be to go back to short lives of great labour and drudgery!
By all means lets try to increase efficiency and reduce waste - but lets not take too much notice of the people who all scream 'doom and gloom' and predict the imminent and disastrous collapse of civilization as we know it!
All the previous predictions have been wrong....
