No, electric capacity has the built-in buffer you describe. But the main driver for ongoing GHG emissions from electricity generation is, of course, generating the electricity. I'm sure there are no formal studies yet as to whether these work from home policies are a net increase in GHG, either within the utility industry specifically (i.e., excluding savings on cars) or overall, but my gut instinct is that it will be a net increase. Distribution to where residential homes are tends to be less efficient, and it's certainly less efficient to heat, cool, and light 1000 houses all day than 1 office building.
