elene - About the sustainable energy vs. nuclear issue - I'm deeply concerned that what we're investing in (admittedly under-deveoped) sustainable technology won't actually reap a positive effect on our energy use in a useful timescale. If, for example, it takes 50 years to recoupe the energy cost of building and maintaining a wind-turbine, and we hit the energy-crunch in 40 years, then all it's done is push us closer to the edge. I'm not saying that's the case with all renewables, they're probably the long-term solution, but in the short term they don't deliver. The only thing we have that does, and doesn't use fossil fuel, is nuclear. I agree about the waste disposal problems, and therefore nuclear energy can only ever be a short term solution (until fusion is managed, or until renewables advance to a state where we can rely on them). It's the only way out of the current short-term mess we're in.
I completely agree with your sentiment about reducing waste and not curtailing technology, that's one of my greatest fears too. There are a significant minority at the edges of those lobbying for sensible, sustainable energy use that seem to want to return us to pre-industrial revolution living. That scares me and makes me less inclined to join my voice in with the overall sense being spoken.
As someone who uses a train to commute to work, I have mixed feelings about cars and efficiency. Given that the car I share with my partner is small, efficient, and well looked-after, by most metrics it is only marginally less efficient than the train. If I could organise a car-share arrangement, it would be moreso. There are occasional situations where people require a car (and I wish they'd introduce one of those pay-as-you-go car schemes in my town so I could get rid of the one we have), and many where they don't, but where I live (the SE of England) the infrastructure is at it's limit already. Trains are full, and they can't run any more on the tracks. Roads are full, and there are traffic jams all the time. We're also running out of fresh water. Short of living elsewhere (and it would be difficult, as there's less work elsewhere) I don't know what can be done to fix this problem, really.
Maybe we need to concentrate on using the advances in communication technology to replace travel, at least to some extent. I suppose that is the only way we can keep the advances we've made and manage our resources more efficiently. |
