Two years ago we bought a Nissan Leaf and a Plug in Hybrid, cut our gasoline use by 80%, added solar. Just added a second system so our electric bill is minimal. Now adding solar on four rental properties here to get the cash flow of about 12%/year on average. I think there are thousands of others who are in some stage of doing the same. The total economic impact between additional revenue +$500 month and savings of $400 /month is about 33% of our mortgage plus our tenants get some savings too.
I think the transition to renewables will be faster than many expect.
