So says Jesse Ausubel of Rockefeller University in New York, writing in the International Journal of Nuclear Governance, Economy and Ecology. The paper appears to be an analysis of the amount of land required per Watt of energy produced.
Biomass energy is also horribly inefficient and destructive of nature. To power a large proportion of the USA, vast areas would need to be shaved or harvested annually. To obtain the same electricity from biomass as from a single nuclear power plant would require 2500 square kilometers of prime Iowa land. "Increased use of biomass fuel in any form is criminal," remarks Ausubel. "Humans must spare land for nature. Every automobile would require a pasture of 1-2 hectares."
Obvious to everyone except greens.
