Installations are different, they encourage those. They purchase power, so costs may be different. Also, I suspect solar farms in WI produce more expensive power than Texas. Ironically wood (corn stalk, grass) pellets aren’t used much here. About as renewable as you get, and no batteries needed, nor wind. But unpopular as it’s burned
Lots more days of sun all year in Texas than WI-no doubt cheaper production. Stoves that use pellets are popular for heating homes and barns in rural areas of the state that don’t have a lot of trees where dead ones can be cut-to minimize forest fire danger, and for firewood-no trees to speak of on plains/prarie, desert-the pellets stoves are expensive to buy, but cheap to operate-not an option for me, however-I’m poor, and there are wooded areas all over here-so a normal woodstove works for me...
