So you're trying to compare no indoor plumbing which can lead to diseases for you and your neighbors to solar panels?
No, I'm saying that everything that goes into new construction is required. Why is this any different and why do you care?
Because for the most part, building codes and regulation are there for a purpose. For one, if you hired a company to build your house, and they are building it the wrong way or in a way that presents a danger to you and others, it's perfectly understandable. You also don't want to get ripped off by them installing something that will cost you a fortune to fix down the road. Those regulations also help protect the buyer of your home if you sell it.
Solar panels? Such regulations are not protecting anybody. So why solar panels? Because environment is a leftist obsession, and we shouldn't allow anybody to write laws based on their personal hangups. If you want to spend the money to save the world, go right ahead. But don't write laws to force me to do the same especially if my political view resents the global warming hoax.
This regulation is there for a purpose whether you acknowledge that or not.
This means that going foreward, new housing will not require any large upscaling of centralized power production. Fewer production facilities running for fewer hours a day. Simpler, more localized and efficient transmission infrasructure. Excess will be put back into the grid and used locally in real time. If you can't see the benefit of that going foreward, then you aren't trying to.
Lastly, less dependency on a huge, outdated and inefficient power grid and transmission system is far better for national security.
Why do you care where the power comes from as long as it works when you flip the switch?
