This is exactly it. Of course battery production is harmful too, but not only is it less harmful than other sources to extract, you also don’t have to burn batteries to generate the power. With fossil fuels, the extraction is massively more harmful and then the use itself creates even more pollution.

Hell yeah, we’ve got a heat pump and we’re in Canada where it can get to -40°C (which is coincidentally also -40°F) and that thing works like a beast. Fortunately we also have the cheapest electricity in North America so the decision was easy.
