I live in Arizona which is fantastic for generation...but it also means an AC load in the summertime that most can't imagine. We'll go for months at a time not only with the daytime high over 100°F (sometimes pushing 120°F or more), but with the overnight lows in the 90s, sometimes upper 90s. As in, you can step outside at seven in the morning and it's already 100°F, or be lounging around at ten at night with it still 110°F outside. I have about a quarter of my quite modest two-bedroom one-bath home's roof covered in panels (both PV and hot water) and I generate half again as much as I use -- enough to also power a future EV. My generic and modest subdivision, which has lots of apartments and thus one of the higher densities in the city, could not quite power the whole city if every square inch of rooftop was covered with panels. Insane summertime AC load and all. And, yes, again: not going to happen in Manhattan. If you live in Minnesota, you might still need gas to survive the winter...but why should the perfect be the enemy of the good? Far better to burn (less) fossil fuels for three months out of the year than to keep burning the same amount year-round.... b& -------------- next part -------------- A non-text attachment was scrubbed...
