Energyskeptic wrote about the ongoing depletion of energy resources and the need to change economic systems. This is advocated by columnists such as Monbiot at The Guardian. So I'll quote a bit from the energy skeptic and then I'm posting my answer:
"Economic growth is an artifact of the use of fossil fuels. Before large amounts of coal were extracted, every upswing in industrial production would be met with a downswing in agricultural production, as the charcoal (from wood) or horse power required by industry reduced the land available for growing food. Every prior industrial revolution collapsed, as growth could not be sustained. But coal broke this cycle and enabled – for a few hundred years – the phenomenon we now call sustained growth."
And here's my answer:
I'm seeing lots of articles and comments by left leaning authors proclaiming we need to change economic systems. The authors live in the USA and Europe, so my guess is they mean changing from capitalism into their personal version of socialism or communism. These guys really seem to believe in the old Soviet worker´s paradise.
Real life experience tells us that communism generates poverty and human rights abuses. They forget it will take economic power to increase the amount of energy we get from sources such as wind and solar. This alternative doesn´t penetrate very well in that crowd because their primary driver is to peddle socialist/communist politics using global warming and resource depletion as an excuse.
