Comment Mud Huts (Score 2) 652
There are a lot of assumptions going on here. First, that anyone in the first world would even seriously consider living the "mud hut" life in the name of climate change. Second, that the ruling class in the first world would ever permit the rest of the world entry into the first world. Third, that energy consumption must be severely restricted since there are no safe ways to produce first world quantities of power absent carbon-based fuels.
The world's present energy mix, and consumption practices are built on a history of cheap, readily available fossil fuels. Properly incentivized (read: the external costs of carbon-based fuels captured), the world's production would quite naturally swing towards "green energy." Any gaps in technology would be researched and quickly filled. Efficiency can and would be found. There's no reason we can't do things differently and yet maintain a high standard of living except that entrenched interests on the production side like it the way it is.
