Renewables Could Rape Nature says Climate Expert

A mass take up of renewable energy could lead to the “rape of nature” according to a leading US scientist.


Interviewed by New Scientist magazine, Jesse Ausubel of the Rockefeller University in New York, claims that renewable fuel sources – namely sun, wind and biomass – are simply “boutique fuels” that require huge areas of land in their production compared with nuclear power facilities.

“If we want to minimise the rape of nature, the best energy solution is increased efficiency, natural gas with carbon capture, and nuclear power,” suggests the conservation biologist and climate change researcher.

According to Ausubel, to generate the same amount of energy as a 1,000 megawatt nuclear power plant using biofuels, 2,500 square kms of prime Midwestern farm land would be required. Although considerably less land intensive, solar would still take up to 150 square kms of photovoltaic cells to produce the equivalent amount of power. Ausubel also claims that an area the size of Texas (780,000 square kms) would be needed to meet North America’s electricity demands via wind power.

Countering Ausubel claims is John Turner of the US government’s National Renewable Energy Laboratory. Turner says that even if the US was solely reliant on solar energy, the land mass required would be less than half the amount of land that has been paved over for highways.

“We could get a quarter of our energy just from covering rooftops of existing buildings,” added the government scientist.
