  • You are mixing up many different things.

    First, you don’t have to install the solar capacity in one huge blob. Solar farms also don’t have to be the only use of the land. You can still farm crops that like shade, you can hold cattle, build the energy storage right beneath the solar farm, a car park or what have you. There is also a lot of currently “wasted space”, such as roof tops or existing car parks. There are also swimming solar pannels that have the added benefit of keeping lake temparatures in check in the summer. You also have wind turbines that can contribute their fair share to the energy mix. So no, you don’t need to build huge over-capacity and you don’t need to bulldoze huge swaths of land to install solar. And the price to build solar and battery storage is still going down.

    Where are the nuclear plants that use “safer fuels”?

    Renewables are cheaper to build and run, meaning that renewable energy is always cheaper than nuclear power. You’d need to artificially limit the amount of renewables companies are allowed to build or subidize nuclear, otherwise renewables will price nuclear out of the market.

    No, solar farms don’t need centralized grids nearly as much as nuclear power does. What is much more important for renewables is monitoring the local grids, so they don’t get overwhelmed by people providing power to the grid with their solar pannels.

    And people already absolutely do provide power to the grid with their own solar pannels, you denying that just shows that you haven’t mich thought about/experienced local “grass roots” energy production. In Germany, the capacity of the local grids is one of two big hurdles renewable energy production is facing right now. Commercial and private energy producers are complaining that the utility companies are forcibly cutting their power plants from the energy grid to stabilize it.

    And like I said in other comments already, hydrogen/natural gas power plants are a much better fit to handle extended lulls in wind and solar.



  • Nuclear is simply incompatible with renewables, if the price tag is of any concern to you. Nuclear reactors take long and cost a lot to build, still aren’t cheap to operate if you include the infrastructure cost of getting, handling and storing the fuel, can’t respond to changing demand quickly and are centralized.

    Nuclear power plants need subsidies over their whole life, mainly to handle the risk inherent with nuclear fuel and the finincial risk of having to handle spent fuel for centuries to come. Nuclear power plants need to run at full power, which costs money every time renewables are pushing the energy price into the negatives. Nuclear power plants need a centralized power grid.

    Renewables work in exactly the opposite way. They are cheap to build and maintain, they are variable and decentralized. So to use renewables effectively, you need to build a decentralized grid and ideally on-premise energy storage.

    Renewable energy simply wins in terms of cost, risk-management and scalability. So the energy grid of the future will be purpose-built to accomodate renewable energy. Trying to force nuclear energy generation into that mix only makes sense, if you have a clear, non-monetary reason to do so, like enriching uranium for bombs. For strictly commercial use, nuclear power is dead.
