Articulating opposition to Islamist fundamentalism from a Muslim perspective.

There is no way to produce "sustainably" as much as humanity is producing now. We need to reduce wasteful consumption.

The article shows how the EROI (energy return on investment) for fossil energy is declining, because we have already extracted most of the easy-to-extract fossil fuel. However, it errs when asserting that renewable energy's EROI is part of the decline.

The EROI for renewable energy is increasing with advancing technology; meanwhile, we have a long way to go before it must decline because all the easy-to-collect renewable energy flow is already being utilized. Even when that happens, we will be able to continue steadily drawing the same amount of renewable energy each year at the same efficiency, as long as the Sun keeps pumping it out as now. In other words, the idea of sustainability does make sense when applied to renewable resources.

I don't think this invalidates the article's overall point however, that we must reduce overall resource use greatly rather than just make some activities "sustainable".
