Getting solar installed on our house, providing well over 100% of our energy needs overall (including car), has left me low-key kind of angry that we, as a society, are letting so much energy just uselessly fall onto structures and the ground when we could be harvesting and using it.
Especially in the US, and especially in homes, we tend to have dark roofs. Sunlight falls on these, heating the building up, then we burn fossil fuels to generate more energy to pump the heat outside. It’s absurd.
I agree. The momentum seems to be building up though, at least in (east) Europe, so there is a glimpse of hope.
Fun fact: we still don't have AC in our house (it's a new-ish building, built 4 years ago) because it's decently insulated (and we live near the mountains). As in your case, our solar produces way over 100% of what we need, so I'm considering just getting AC to use the sun to cool the house if needed :)
On X/Twitter, I'm sometimes seeing graphs comparing energy usage per capita in the US vs the EU and China, with the narrative that the US is 'better' in some way because the higher energy usage.
And then there is stuff like the above indeed, uselessly wasting energy while things could be so much more efficient.
For years, maybe 20 now, I have seen a few people that seem reputable in terms of their positions and data they project that says that we should not have as many solar panels as we do. It is restrictions on rare materials etc. Some of them are probably paid to have this position, others seem genuine.
And yet, look at what is happening. Year after year the exponential growth continues without a blip! It is one of those things that looked impossible initially but obvious in retrospect.
My broader long term fear is that if we essentially get "limitless" energy, we continue to harm the ecosystem in other ways. Like giving a drug addict a limitless bank account. But we are still a long way from that point.
Air conditioning is a substantial load on the grid and those that need it most are likely better suited to solar (more sun to heat, more sun to generate electricity). As you noted, it pays for itself and then is "free".
In a different timeline, we'd be investing in the country via zero/low-interest loans to encourage every homeowner to leverage this. It's a win for everybody.
this is indeed a flaw in modern societies, we get lost in technological "progress" and become blind and dumb
