Energy from biomass
A new report suggests that we should be able to feed a growing population, conserve the environment and produce 20% of world energy needs from biomass by making “the best use of agricultural residues, energy crops and waste materials”.
The report by the UK Energy Research Centre (UKERC) can be downloaded from here.
I’m not sure how well they took into account the impact of climate change on agricultural productivity. They did consider an IPCC report on renewable energy (large pdf) and a study by the German Advisory Council on Climate Change (WBGU). Of the latter they said:
The WGBU08 report is arguably the most comprehensive study of the implications of growing bio-energy crops considered here. The approach uses a spatially explicit yield model for terrestrial productivity (LPjmL) driven by IPCC climate models, and scenarios. (p. 35)
You would need to go back to those studies to see what changes of weather, melting glaciers, sea penetration of river deltas etc were taken into account. Continue reading Climate clippings 56
