It makes economic sense when you do all the calculations of money you're going to save and the government has a good subsidy program. Our payback is 3.5 years and our return on investment is high. These things all together convinced us it was the right thing to do. It's hard to invest your money in something and get your pay back that fast. I think it makes a lot of sense both financially and environmentally for people to do.
