Dall’analisi di Richard Heinberg, Asia Times. Despite all the renewable-energy investments and installations, actual global greenhouse gas emissions keep increasing. That’s largely due to economic growth: While renewable energy supplies have expanded in recent years, world energy usage has ballooned even more – with the difference being supplied by fossil fuels. The more the world economy grows, the harder it is for additions of renewable energy to turn the tide by actually replacing energy from fossil fuels, rather than just adding to it. The notion of voluntarily reining in economic growth in order to minimize climate change and make it easier to replace fossil fuels is political anathema not just in the rich countries, whose people have gotten used to consuming at extraordinarily high rates, but even more so in poorer countries, which have been promised the opportunity to “develop.”.
