OK, you really want to do right by the environment and stop using all that coal fired electricity. The problem is you don’t have an extra ten to twenty thousand lying around the house to buy a photovoltaic (PV) system, or if you do, you’ve had your eye on that new diamond encrusted turnip twaddler that the Johnsons just bought. Sound familiar? Sure it does, and who among us doesn’t want a diamond encrusted turnip twaddler? (The ruby ones can be so frustrating right?)
Well let me tell you about my friend Phu. Phu is the way cool principal of a local high school and is married to a way awesome woman named Melanie who’s an English teacher at the same school. They’re wicked smart! Now we all know that teachers are among the highest paid professionals on the planet (aren’t they?) so Phu and his missus should be able to buy a photovoltaic system, pop it on their roof, and cut out the coal without having to even think about it. Well, maybe in the world I’ve created in my mind, but in the real world, Phu is in the same boat as most of us and can’t throw down the benjamins for a full system (plus they have a baby on the way, so its not exactly squander time if you know what I mean).
So Phu and Mel sat down, crunched some numbers, and did some research. One option was to pay a lot to put a system on the house and kick their coal habit, and another option was to pay nothing to put a system on the house and kick their coal habit. Guess which one way they chose (remember, I said they were wicked smart).
