Latest column: the dependence of wind turbine making on fossil fuels

Posted on

Can you make a wind turbine without fossil fuels? This question appears to have not been asked by the various people telling us 100% renewables is achievable. My latest piece at Energy Collective looks at the problems, read it here. Making stuff is perhaps the greatest de-carbonisation challenge. We now make things like steel, cement and aluminium extremely efficiently. And some things like steel making or cement making currently cannot be done without emitting lots of CO2 (currently iron, steel and cement are about 12% of global CO2 emissions).

A book I recommend on the subject is Allwood and Cullen’s, which is freely available here.

    I saw this press (undetailed) release awhile back: http://web.mit.edu/newsoffice/2013/steel-without-greenhouse-gas-emissions-0508.html

    It is a process for making steel economically using molten oxide electrolysis. It is still in the lab stage.
