Production of renewables has, in fact, increased by 10x several times over, and is still increasing as costs continue on down.
Storage will not be in batteries, so it doesn't matter what production rate of batteries is. Huge amounts of pumped hydro are being built out right now. Bulk storage will be in synthetic chemicals, principally anhydrous ammonia and hydrogen, which besides being storable, are both readily transportable and valuable as industrial feedstock.
> implies needing other sources of power for when the sun isn't shining in the wind is not blowing
The sun is always shining somewhere, and the wind is always blowing somewhere. So, you just need to be equipped to transport the energy from somewhere to here. That will probably be, most often, via high-voltage transmission line, but also via supertanker. Absent transmission lines, you only need to stockpile enough to hold out until a shipment arrives from the tropics.
Recycling solar panels is not being done at scale because very few panels have aged out, yet. There is, furthermore, a ready market for panels with degraded output. In any case, even if they were just piled up somewhere, that is no more a problem than doing the same thing with eroded wind turbine blades. There is plenty of room to park as much of them as you like. They don't even need a roof overhead.
When the CdTe panels finally age out, there will be a ready market for the scrap, because Cd and Te are valuable.
Building solar over pasture does not, in fact, substantially increase installation cost. But it does eliminate the need to buy land to use. Siting over cropland will be done more for the benefit of the crops, while providing revenue year-round.
But in any case there is absolutely no shortage of suitable land for solar, even without co-siting. So, farmers can take up solar or not, at their option. Many will, probably most won't.
- gregwebs 5y agoEvery scaling process reaches bottlenecks. Solar panels increased in price in 2021/2022 due to the rising costs of the raw materials and there's no quick fix to this fundamental issue. I love your future Utopia. I just don't want to bet my future on all these new experiments coming together and working out perfectly. I think you are front-running every single energy source or technology mentioned. Even pumped hydro, which is a great and old technology- but it had it's first new project in the US approved in 30 years and it remains to be seen when it will actually be built because there are land use issues [1]. The war in Ukraine is creating a crisis of energy security. We need to ask ourselves whether we want to handle the intermittency of renewables by transporting energy all around the world with new experimental techniques or just build some nuclear plants in our own country and avoid all the geopolitics.
