    Utility-scale battery storage costs decreased nearly 70% between 2015 and 2018

    So we are looking at much lower numbers in a few years as the trend has continued.

    You can save money with solar and batteries, but only after about 30 years.

    That is false.

    Example for US around 7.5 years with tax credit -> pessimistically 15 years

    Example for Germany 7 years w.o., 12.5 years with battery storage. -> pessimistically 20 years.

    hat’s a much longer payback time than any other forms like nuclear.

    That is false. Take the spanish nuclear industry for example

    Nuclear power plants are not amortized. Every year they invest around 300 million Euro. Nuclear generation is currently incurring losses due to a disproportionate, discriminatory and confiscatory taxation.

    The amortization of nuclear power plants is not complete. In fact, from this time to the end of its operation it will be necessary to invest around €3 billion to maintain the plants in optimal safety and reliability conditions.

    Take Germany for an example

    Bei neugebauten Kernkraftwerken in Deutschland werden laut dem Bundesministerium für Wirtschaft und Klimaschutz Gestehungskosten zwischen 14 und 19 Cent pro Kilowattstunde erwartet. Das Forum Ökologisch-Soziale Marktwirtschaft gibt in einer Studie für Greenpeace Energy an, dass die gesamtgesellschaftlichen Kosten in Deutschland im Jahr 2021 zwischen 26 und 38 Cent pro Kilowattstunde lagen.

    Allerdings geraten auch abgeschriebene Kernkraftwerke in Märkten, in denen die Strompreise infolge aktueller wirtschaftlicher Entwicklungen wie des Schiefergasbooms in den USA sowie des Ausbaus von erneuerbaren Energien in vielen Staaten der Welt gefallen sind, wirtschaftlich unter Druck. In den USA wurden deshalb in den letzten Jahren mehrere Kernkraftwerke lange vor ihrem genehmigten Laufzeitende außer Betrieb genommen.

    So nuclear power at best only generates profits if the market is arbitrarily restricted and the power plants are protected against low energy prices, which in turn means to stifle economic growth and competitiveness in everything else.

    More realistically new nuclear power plants are a mass grave of capital. See UKs hinkley point now at more than 50 billion € for 3.2 GW. That is a whooping 15,625 €/kW.
