Renewables don't work

Bishop Hill in Energy: solar, Energy: wind

The message that renewables simply don't work seems to be getting around. John Morgan, an Australian industrial scientist working in the area of grid storage technologies, has been looking at the EROI measure that was discussed at BH a few weeks back and has concluded that there is a bit of a problem with the whole concept of grid storage:

Several recent analyses of the inputs to our energy systems indicate that, against expectations, energy storage cannot solve the problem of intermittency of wind or solar power.  Not for reasons of technical performance, cost, or storage capacity, but for something more intractable: there is not enough surplus energy left over after construction of the generators and the storage system to power our present civilization.

Given the amount we have lavished on renewables in this country, Morgan's conclusions could be viewed as just more than slightly unfortunate.
