- pfdietz 6y agoIsn't that the site that argues the UK cannot get by with renewables, but assumes large amounts of biomass are needed to be grown locally?
- philipkglass 6y agoIt's from 2007 and will not get an update since the author has died. I do like it for taking a quantitative approach even though the assumptions used are increasingly outdated. Here's the summary page where the author asked if the UK could supply its energy needs from renewables alone: http://www.withouthotair.com/c18/page_103.shtml http://www.withouthotair.com/c18/page_103.shtml The answer was "not quite." However, he assumed that utility scale solar farms would be using 10% efficient panels. 20% are now widely available. So let's make these two quick edits: - Assume that solar farms provide double the energy from doubled panel efficiency. - Drop biomass, because it's unneeded with better solar farms. With these changes the renewable energy supply of 206 kWh/person/day exceeds modeled demand of 195 kWh/person/day. Making some other simple updates like assuming that car transportation is mostly electrified would further increase the margin of safety.
