The point isn't that a stove uses more than a container ship -- where did you get that idea? It's that "I can't figure out how to work an electric stove" is a relatively frivolous reason to burn fossil fuels.
My point was why don't we fix the very obvious and low hanging fruit like cargo ships that run on sludge, fix that first before you tell me and millions of others that "we don't know how to use electric stoves"
