Have you thought about installing solar? I had 19 panels installed in December, added 4 more on my own in early April (didn't think I was going to cover my bill). But even for the months of June and July, I'm still overproducing, despite the AC nearly being always on. If I do end up overproducing for the year, I'm going to install a mini-split for heat. It's going to take me as little as 5, but not more than 7 years to pay for system. My new meter hit 565 kW in February, but it's now nearly 1 mW in the negative.
