    Nuclear power

    That paper is not interesting, it's sad. It's so full of errors I don't know where to begin. Nonsense. Wind and solar are prone to common mode failures in entire continents at a time. The phenomena causing this are so common as to have their own traditional names: "lull" and "cloudy". I...

    Nuclear power

    Not quite. If you agree we need nuclear for baseload, then we're getting close to agreement. My position is that we need nuclear for baseload, renewables with storage for load following where licensing nukes for that role is too expensive, renewables with storage for peak demand, and gas...

    Nuclear power

    A suggestion for generating electricity without CO2 emissions: The problem that needs to be solved is to always be able to meet demand exactly, without emitting CO2, with as small an environmental impact as possible, and it needs to happen as soon as possible. Base load can be handled by...

    That just reduces the risk of overgeneration. It doesn't improve availability at all. I agree to that, of course. But that situation will not continue indefinitely. Currently, there is still extra balancing capability in the grid, so backup on a grand scale is not yet necessary. That will...

    Assign a cost to CO2 emissions. Make balancing capability a tradable asset. Make availability guarantees a tradable asset. Require intermittent sources to buy balancing capability and guaranteed availability. Let the market sort it out. Self generation is ok, but you would have to buy balancing...

    Nuclear power

    That's because a capacity rating is kind of irrelevant for a technology that just produces power, and continues to do so, day in and day out, for 60 years or so (ok, ok, there will be planned outages and the occasional hiccup, but these things happen one at a time). If you want to replace the...

    Statement A: "Battery storage can be used to capture the peak solar output and store it for use when the sun is below the horizon, and this is economically attractive given that the required reliability is supplied by the grid for free." Statement B: "Battery storage can be used to make a power...

    And you base that statement on exactly which N.U.M.B.E.R.S, nwdiver? You speak as though that curve was a divine law, outside of human influence. It isn't, it is the result of current policy, which massively subsidises essentially useless wind and solar power, by allowing them to parasitize...

    Thanks for that. There isn't much to understand or argue about. The German data is real, and they have so much renewables that it covers the entire demand when conditions are favorable. Still, they have weeks of output well below 10 %. Yes, currently no business case for large scale...

    Well, I guess he assumed that people would read more than just the chapter titles. What part of "almost zero solar output and almost zero wind output for a week" do you not understand? An estimate of the cost of your nice and shiny storage system is precisely what I'm working towards. Before...

    First he breaks down and estimates current British energy consumption. The 40 kWh/d figure on page 103 was first calculated on page 29. This is in the first part of the book, called "Numbers, not adjectives". It's important to first find out where we are, to be able to improve the situation...

    No, you really need to read the whole book. MacKay is a doctor of physics and professor, and was the chief scientific advisor to the UK Department of Energy and Climate Change until 2014. He's a careful scientist. He first breaks down and estimates all of Britain's energy consumption. Then he...

    You wrote that wind and solar compliment each other very well. I showed that they do not. I am trying to establish the facts we need to be able to get an idea of the cost of the grid you propose. I'm aware that the energy is there, but the fact that there are vast amounts of energy out there...

    I'll get to that eventually. I had no problems reading them. Are you sure you didn't just close your eyes? I beg to differ. Take a look at these two graphs from page 3 of this article: Renewable Intermittency Is Real | POWER Magazine This proves that the combination of wind and solar is...

    Nuclear power

    I wrote this in response to Robert.Boston yesterday: "True, but that argument fails to take into account the fact that mechanical problems and fuel supply issues usually happen one at a time, whereas wind and solar frequently disappear completely across vast regions." There is a big...
