One of my most downvoted comments in HN was simply asking if the construction of a wind turbine ever offsets the CO2 to produce it... tons of diesel to mine raw materials, coal to smelt steel, manufacture, transport, installation, and then theres the question: what do you do with giant used carbon fiber blades (besides burying them, generating tons of waste: https://cen.acs.org/environment/recycling/companies-recycle-wind-turbine-blades/100/i27 https://cen.acs.org/environment/recycling/companies-recycle-...) Alas, even bringing this very valid science question generates sneers online and in previous comments there's already comments stating consipiracy theories about oil companies. What we would probably discover is nothing is actually carbon negative, some are just less worse than others. I'd like to know the actual answers so we can affect real change, rather than just clinging to our crystals.
