This while we have a global population still growing, emerging consumerism in the Third World, and an entire society sustained by the consumption of energy.
And where, exactly is all of that energy going to come from? Oil, Coal, Uranium? All of those things
will run out, sooner or later. But, at the moment they are relatively cheap. As far as I'm concerned, the time is now to move us away from those energy sources and towards renewables. If a carbon tax is part of that shift, then so be it.
The other thing is that it is almost criminal, IMHO, to still be looking at oil as an energy source, compared to its other uses. There are lots of other ways of powering our society, but not as many efficient ways of lubricating things, making plastics, fertiliser, and the other 1001 things that we make from oil...
I've been following this thread a little bit over the last few days ... not sure who that was you were quoting North Shore (
just briefly scrolled back a few posts, but didn't see that one) ... but in any case, its an interesting line of thought.
I got to thinking about that one particular point "
will require such a radical change in lifestyle that it is virtually incomprehensible" ... and I was reminded of a grade school project I had as a kid. It was to interview an elderly relative about their life ... I interviewed my grandmother. And when I think about how vastly different the world was from when my grandparents were kids to when I was the same age, the changes in lifestyle
were incomprehensible.
One of her earliest memories was seeing soldiers returning from WWI. My grandparents grew up (
lets round it off to their youth & teen years, being in the 1920's & 30's) in the UK. Houses didn't have central heating, and what heat they had was coal. Most homes didn't have much in the way of indoor plumbing. Music was listened to on a gramophone. Aviation was in its infancy. No telephone, but the post man delivered upwards of 3 or 4 times a day. Cars were rare.
In their lifetimes, communications went from the post, to telephone, to faxes & email. Air travel was born and progressed up to jumbo jets and the Concord. Space travel came into existence. Cooking went from a coal fire to a microwave. Music went from the gramophone to records to reel-to-reel, then 8 track, cassettes, CDs and eventually digital (MP3s, etc).
Talk about incomprehensible, eh?
Compare life in 1930 vs 1970 or 75. You don't think we have the technological ability to shift our way of life to hit a target 40 years away? That's not what history teaches.
