There’s a funny thing about the way we often discuss solar power compared to other household goods. We don’t often refer to cars as “investments.” We also don’t tend to do so with TVs, game consoles, refrigerators, ovens, etc.
Granted, when we’re very attentive to energy efficiency, we may do so with some electronics and appliances. However, I don’t think that’s the norm.
But do so obsessively with solar power. It’s all about “investment” and return on investment (ROI). There are clear arguments as to why solar is different from some of the above, but there are also arguments for why it’s in the same boat.
For example, we need refrigerators, ovens, and electricity. Our choice is simply between which is the best option. Looking at solar vs other electricity options overall, solar is clearly the best option. People know this. Or, at least, they think they know this (but haven’t done an in-depth comparison) — which is just as good. Yet, solar is still on a tiny percentage of our roofs, and the decision to put it on one’s roof is almost always looked at from an investment or financial comparison point of view.
