Some random comments.

Let us be clear, the issue is that people should not emit more greenhouse gases than the environment can handle, if we wish our ‘civilization’ to survive – not that we should not emit any. Not emitting any greenhouse gases is impossible, and the system emits and reprocesses these emissions naturally, just not as much as we are currently emitting.

Coal is particularly bad in terms of the poisons it emits at all stages in its production and use. There is very little positive to say about coal (that is not in the ground) at this stage in our history. Coal mining and power probably needs to be eliminated, as there is no evidence that coal can be made ‘clean’ or environmentally friendly to the degree that we need it to be.

We probably also need to work at changing what seems to constitute modern life. Modern life is not a product of free choice but of what we were offered and chose within a particular set of social arrangements that did not value ecological survival.

That needs to change – and frankly I’m not sure people really ‘need’ or ‘want’ disposable bottles, polluting and failing concrete, coal power, massive amounts of beef, destroyed fishing grounds, and so on. This can be modified, and hopefully will modify.

It will be hard of course. Some of the problem may well be that the system we live in seems to create a psycho-spiritual emptiness which we fill by purchasing products – and this keeps us acting as wage slaves and generally making ourselves feel empty. This is part of the pattern of domination which we often call neoliberalism, but is probably better ‘capitalist plutocracy’.

Recognising plutocracy is important. I’ve rarely met anyone who is interested in renewables, who is not aware that these new technologies are being resisted by people who have lots of wealth, power, status and symbolic resonance tied up in fossil fuels. It’s pretty much an every day experience, and the established powers have heaps of money to throw around to influence the debate. Without them, and without the triumph of neoliberalism, we probably would not be having a debate; we would be engaged in finding the best solutions. Resisting plutocracy is important but difficult.

My main problem with the “energy problem” is that it distracts attention from the other ecological crises which are happening simultaneously. These are produced by building (concrete), mining, farming methods and so on, which are destroying our fresh water supplies, downing our oxygen supplies, wrecking the phosphorus cycle, killing the oceans and so on.

To be real, we need a lot more action on a lot more fronts.
