Yep, ROI is the key
Yep, ROI is the key. I’d love to have a roof covered in solar panels to reduce the outrageous electric bills I’m paying every month. Unfortunately, even if they double my rates, it’s still cheaper to just buy it from the power company than to install either solar or wind to produce my own.
If you’re a hardcore tree hugger, I suppose that’s not such a problem. However, I’m much more interested in saving my wallet than I am in saving the planet, and there are many others like me.
Make this stuff affordable, and people will flock to it. Until then, it’s going to be the exclusive domain of rich hippies.
