I'm installing rooftop solar. It makes me feel good.
Its output is an order of magnitude more expensive than utility-scale solar behind the meter. The solution has to be renewables + storage + zero-carbon baseload, i.e. nuclear. Everything else, including calls for rooftop solar, is a distraction.
Edit: (You might say, isn't cost-efficient yet. For all I know parking shade structures could have turned the corner already; they used to require tax incentives to break even.)
Walmart has more parking lot space than roof space, and parking lot solar doubles as covered parking, which itself has value.
Even if both were cost effective, it makes sense to do parking lot first (with accompanying PR) and then rooftop later (with another round of PR).
I live in a highrise and when I look down, almost every single building, residential, office space, government, even schools, they all have solar on the roof. Almost every home owner has solar on their roof as well. It’s basically just rental properties without.
Like I said, the problem is policy.
Clearly you never talked with any Austrian. Mention nuclear energy and you will be compared to Hitler.
EU is on the bring to mark nuclear energy as non-green, what then?
Yes we need other forms of energy production, but it's suicidal to try to just use them in this supply-pushing way, we don't have time to faff around with that.
