A comment on Directly converting CO2 into a gasoline fuel (2017). Parent comment
1) Assume a 1x1m solar panel generates 150W at peak.
2) It won't manage that all the time, far from it. Lets say it generates 300Wh per sq. meter. per day, or 110kWh/m^2/year.
To achieve 80000TWh we'd need about 730million 1x1m panels. For comparison, google says the land area of New York city is 783million m2.
Of course it's not just solar, throw in geothermal, tidal and wind too
