On the topic, as an ecology student, I have to say that I disagree with the article on that the power draw is increasing due to people using more and thus we can go back. There are several ideas about how to solve the ecological crisis, and the "going back" view is one of them, but it's not a credible view. We could throw away all the technology and go live like in medieval times, and it would only make everyone less happy. It wouldn't actually help the environment as much, because technology also brings efficiency. With today's population growth, we absolutely cannot afford such a loss of efficiency.
Cutting down on unnecessary, waste usage is something we could realistically do, yes, but it's a gradual shift. It's also something that is actually happening as we speak (and if World War III doesn't start, it should continue). A hundred years ago nobody thought about such things, while nowadays people are markedly starting to realise that energy saving, along with other environmentally-friendlier things like recycling, is important. It can be seen in the changing laws (like the European Union banning incandescent light manufacturing and now about to ban halogen bulbs as well), changing attitudes of everyday people (cashiers actually asking people if they want a plastic bag instead of just automatically giving one etc.). And everyone can indeed participate in this shift (albeit the biggest effect is gained through laws and education, the latter to make sure people understand why the former are needed).
Changing the economy could help, but we don't know a model which would work better than what we have. Communism is perfect ? in theory; in nobody tried to game the system, everyone would be happy, but due to humans being selfish goats it doesn't work in practice. Capitalism is more about making it hard to game the system, but it's an imperfect system from the get-go, mostly built around increasing consumption (which today is bad, because we don't have the resources to do that any more). It's also fairly dated, not that well suited to the current virtual goods and whatnot. The system in Star Trek could be a preview of what is to come (3D printers producing all the goods and therefore no real goods needed; money eliminated, everyone working to become known, famous, satisfy curiosity or to help humanity as a whole), but it probably also wouldn't work due to being too perfect. Same with political systems ? democracy is perfect, but it also assumes everyone has perfect information and can vote; dictatorships are the opposite, you have to hope the dictator knows what he's doing, but if he does, then it works better under imperfect conditions. And parliaments are the middle ground between the two, people vote for who they think know what they're doing (often times it happens that they do not, or try gaming the system).
So with regards to the economy, perhaps it just needs revising. Changing some priorities, defining new patterns, that sort of thing. And it should be gradual. Which might mean it's happening already (Kickstarter is a good step in that direction). So I'm pretty hopeful about this, too.
So if we have a problem, and things are changing for the better, everything just comes down to time and black swans. Is the change happening quickly enough? Maybe, maybe not, we can't tell from where we are at the moment. "Enough" is also subjective. We can often calculate some of that (with climate change and such), but black swan events can happen and throw everything out of balance. If the war did start, suddenly we would have a much harder time meeting those deadlines; unless we'd get a counter-swan and someone would invent cold fusion for military purposes, which would then solve the energy demand problem...
