HN is not Science or Nature. There is no need to provide in-depth citations to counter shallow dismissals. The best I can offer is a "most experts agree that carbon neutral grids are both feasible and desirable".
Funny thing about HN - until 6 months ago, I was working alongside them at the DOE and had been since 2008 or 2013 (depending if you include grad grants or not) developing electrochemical cells to significantly curtail CO2 emissions from the grid.
I have said experts personal cell phone numbers.
