    "U.S. Renewables – Current and Potential Output":

    https://www.masterresource.org/renewable-energy/u-s-renewables-update-2019/

    excerpt:

    Conclusion: Too Much Renewables

    More than $3 trillion has been spent on the renewable energy effort since 2004, and the figure has now stabilized at about $300 billion for each one of the last six years.[6] For a cost comparison, the earlier mentioned nuclear power plant – another source of clean and green electricity and also heat – cost $4 million, inflation adjusted. Not billions, just millions. Hundreds of them could have been producing power for the money spent on renewables today, making our country and the world cleaner and richer as a result.

    As to the likelihood of the W&S output influencing climate change, those 9.5% of electricity, which is 1% of total U.S. energy consumption, is unlikely to influence anything except our pockets. And we have no means of measuring those causes and effects reliably as yet.

    Despite this discouraging renewable energy history, documented numerically in voluminous literature, it is politics, not economy, that forces our country and individual states continue year after year to commit us, the tax- and rate- payers, to the goals of producing “20, 50, …. 100 percent of energy from clean, renewable sources in 5, 10 …. 20 years.”

    Those goals a being set despite seeing them not met, and budgets going red repeatedly, for a half a century by now. On top of that some proponents claim this energy to mean the US energy overall, not just the electrical portion of it. That would raise the target sevenfold.

    Citing nuclear as cost-effective in comparison to renewables which would take "years" seems like total horse ****.

    It's pretty damn expensive to build a nuclear plant and given what we saw at Fukushima the safety margins for them have gone up driving up the cost and construction time even more.

    Addressing this. The issue of how much area is needed is important but also ignores that new technology in both solar and wind is allowing energy production in all places. Photovoltaic building materials are making it possible to generate power on most structures. With photovoltaic glass all of those big curtain walls could be generating electricity while still keeping much of the same aesthetics and function.


    With wind we've come to think of giant windfarms but turbines could be generated on top of skyscrapers too.

    Also considering anywhere there is motion you can generate electricity. Given how much flood control is an issue with Houston new flood control infrastructure could also generate power since flood control is about the control and movement of water. Reservoirs and even large cisterns could be equipped with turbines that generate power both when they are filled and also as they drain out.

    This is one of those reasons why the measures for addressing climate change are important even if climate change wasn't an issue. Figuring out how to generate electricity practically anywhere means we can build a distributed, robust grid with a lot of redundancy.
