Ardy, so many of these investments come with massive subsidies. My bro is a Wall street type, his boss is an insider. I've had lunch with him a few times as he considers different investments. He has on his Wall Street staff several federal government grant writers and several full time lobbyists. When my bros "free market" Wall Street insider considers a deal one of the first things he does is consider the potential subsidies available from Washington. I thought I knew people in DC, this guy has the cell phone number for most of the big names you hear about on TV.
While it is impressive it is massively disgusting. Wall Street is not about free markets or capitalism, it is about crony-ism and tax handouts. When a deal hinges on money from DC, something is very wrong.
As for a monthly electric bill being $2/mo, I don't doubt it. About 6 months ago I had a solar firm do a quick estimate on my home to take it off the grid via solar. I could post the actual estimate though in order to drop my bill down to zero I would need to spend over $50k in solar panels, and that includes tax subsidies. The subsidies means you folks get to help buy solar panels, batteries, etc for my house. (I'll send you a Christmas card for the help.)
I pay an average of $244 a month, just did taxes to IRS. At over $50,000 it would take me over 17 years. And pray I don't need repairs or something wears out. This is why average people do not invest in them. All things considered, they do not pay for themselves.
