@KimSJ @ChrisMayLA6 Not questions I can answer, not having done the underlying research. Your guesses sound plausible.I would say that you have little control over your carbon footprint from electricity use. Your provider has the control in shifting to renewables from fossil fuels.You *can* reduce your consumption to a degree, and if viable install solar panels on your house, but otherwise are at the mercy of the power generator who supplies you.That is, many emissions are upstream.
