Massive roll-outs of either takes a lot of time and resources. There's also no guarantee that a build-out starting today will even be relevant in 13 years - just look at the warpspeed progress solar panel technology has enjoyed in the past decade. It's a lot easier to hand-wave away these concerns than it is to actually build them out. Just look at warehouse roofspace in this state - nearly all of which are perfectly flat and huge (thousands, tens of thousands or hundreds of thousands of square footage) - but few are covered in solar panels. These things are incredibly expensive, and need to return the investment. We can't pretend the last 20 years of snail-paced build-outs are just because people don't care...
