It is pretty well known at this point that Mr. Money Mustache is enamored with solar power. Besides the obvious Sci-Fi coolness of it (Electricity, Satellites, Futuristic Robots!) and the eco-friendliness of it (energy with zero noise or pollution), in the last five years the money side of things has finally matured, so that solar power is now the cheapest way to make electricity – even before you account for the added bonus of any available subsidies and the benefits of pollution-free living.
It works for individuals: In many cases, if you can get a good rack of solar panels on your roof, your monthly savings will be equivalent to making an investment that performs better than the stock market. But the numbers look even better as your solar setup becomes larger, like if you’re running a solar energy utility or a community solar farm.
