I have solar panels on my roof. They were cost effective only because of massive subsidies at the state and federal level and huge taxes on electricity bought from the power company. They don't work at night, on rainy days or even all that well in the winter. Natural gas plants are on standby to make up any power I need,
Telsa is a govt subsidized toy for the rich with a limited range. Probably more limited if you run the AC. Most people don't have solar panels on their roof and will charge it from the grid. Most electric on the grid comes from natural gas. 80% of MHR production is natural gas. Hard to see how this hurts MHR.
