For a lot of the world, the sunniest places are also the most agriculturally productive. Once you do get a desert installation, how would you get power from the desolate deserts to the places where power is used? There aren't a lot of people there, for obvious reasons. It's harder to send electrons in sufficient quantity than oil or coal in a lot of places. It's not an insurmountable problem, but it is an intimidating and expensive one. There have been some good strides forward made in the deserts near California, Arizona, etc, which is a perfect place for this kind of thing, but if you don't have a desert nearby...We really do need better energy storage. One problem is that things do live in the desert, so there are still environmental impacts that people aren't really sure how to measure. Wind farms have bird-killing and noise issues, I know, but I haven't been following desert solar installations enough to track how reliably they've managed to get environmental indicators pinned down.
Solar thermal is more reliable than wind, but solar panels are not, and neither as much as coal because of transportation difficulties, as far as I understand. Thermal energy in general is much more reliable and understood than other forms, but consumer understanding is a little limited on the physics behind it which is limiting adoption. Last I head hi-tech solar installations were fairly finicky in terms of how stable their conditions needed to be, although the low-tech plastic-sheet ones are of course fairly sturdy.
A few years ago I know some places were trying to use kinetic wave energy to provide power. Does anyone know how that's turned out? It would be interesting to see if that has the same problems as hydro-based energy storage.
One theme that pops up a lot with the carbon tax is the idea that we can live a life completely free of impact. We can't, and in some ways we really shouldn't try for it. The issue as I see it isn't one of eliminating the use of certain resources, but of using all our resources in a an efficient and effective manner. I don't think that a carbon tax will accomplish that. I do think it will encourage a lot of politicking, lobbying and fraud. I think it tries to simplify a complex subject based on unproven assumptions, which is always a bad way to make policy decisions.
If you mean, putting something unnatural into a place that can't handle it effectively through natural processes, I'm going to laugh. Carbon, methane and similar chemicals are natural substances, which can be dealt with by natural processes. They're supposed to be in the atmosphere to keep the earth livable. We may be dumping too much at one time, but we don't know what effect that has on a system as complex as the earth's, and we don't know that the climate is even changing permanently or if this is simply nature's RNG throwing some wild years, or if there's solar activity which is causing changes... We don't understand the earth's climate and we're trying to control it. That's short-sighted and childish.
Oh I see, you're a climate change sceptic. Well that explains that.
As I've said several time in this thread, the earth's climate is changing, just like it has for the past billion years. We do not know enough about the earth's climate to say which change will have which effect. I strongly dislike reasoning in advance of the data. I've worked with complex systems enough to know that rushing in with untested changes is almost always a bad idea.
Geological time is measured in centuries and millennia, not a decade or even 5 decades. A few decades ago, scientists thought we were heading for another ice age. Now they think something different. In a few decades they will think something different yet again. We should stop focusing on changing things outside of our control, like the amount of carbon in the atmosphere, and start really thinking about lifestyle changes and a focus on moderation. Carbon taxes are a lazy stopgap measure that doesn't address the underlying problems.
