    cheaper and vastly safer alternative techs are available?

    That’s the problem “cheaper and vastly safer” alternatives AREN’T always available. People continue to talk up Solar, and Wind, but they’re not viable for a majority of users of coal and natural gas plants. To produce the power that Nuclear does in square mile of land, you need 50 square miles of solar at least, and over 360 square miles for Wind. And that’s also saying you need viable places, because Wind turbines can’t just be thrown up anywhere, nor can solar.

    Coal and Natural gas is more efficient by a factor of at least 10 in land space.

    If you’re in the middle of nowhere, that’s viable, if you live in a big city, that’s going to become a problem quickly.

      Inkai uranium mine produces about 40W/m^2 in fuel for the actively leeched land where everything is killed by the sulfuric acid and vehicle movement.

      If you include the 15km buffer where you can’t live or eat anything it’s about 20W/m^2

      Solar averages 20-50W/m^2 with current tech.

      Rooftop solar uses no land. Agrivoltaics can have negative land use (adding the solar reduces the amount of land needed for the crops under it). Roughly 30m^2 of roof + 30m^s of facade or wall is sufficient for the average high income country european’s final energy use.

      Solar uses a strict subset of the materials needed for a nuclear plant, so land use from the uranium mining is in addition to construction.

      Like every pro-nuke lie, your land use pearl clutching is the oppksite of the truth.

      Yeah, but since there are no moving parts and no emissions, you can site solar panels in places you could never site a nuclear power plant. You can even put them on farms, which is actually of interest to farmers now since climate change means many farms are dealing with excess heat stress and water retention issues in their soil. Revenue-generating shade devices that protect their yields are of interest to farmers. There are a million ways you can creatively use wind and solar technologies because they’re not just inherently extremely harmful and dangerous.

      Cf. agrisolar.

      Go ahead and put a nuclear power plant anywhere and continue to use that land for anything else. Or cover a city’s rooftops in nuclear reactors. Go right ahead, I’m sure nobody will have anything to say about that.

      Your argument sounds great as long as we forget literally all of the specific characteristics of all of these technologies that differentiate them other than power output. Only thinking about power output is why we’re dealing with a 10-dimensional stack of environmental problems only the largest of which is climate change.

      EDIT Made some tweaks after posting sorry if you were replying.

      The statement that “cheaper and vastly safer alternative techs are NOT always available” is not accurate. Solar and wind energy are becoming more viable as technology improves, and the land requirements for these technologies are not as significant as they once were. In addition, coal and natural gas are not as safe as they are often made out to be. Coal mining is a dangerous occupation, and coal-fired power plants can release harmful pollutants into the air. Natural gas is also a fossil fuel, and its combustion releases greenhouse gases into the atmosphere.

      The cost of coal and natural gas is likely to increase in the future, as the world’s reserves of these resources dwindle. The environmental impacts of coal and natural gas are also becoming increasingly well-known, and public pressure is growing for a transition to cleaner energy sources. The development of new technologies, such as battery storage and smart grids, is making it easier to integrate renewable energy sources into the electricity grid.

      In conclusion, there are a number of reasons to believe that cheaper and vastly safer alternative technologies to coal and natural gas are becoming more available. These technologies offer a number of advantages over traditional fossil fuels, and they are likely to play an increasingly important role in the global energy mix in the years to come.
