Wind and Solar diurnal and seasonal variations require energy storage

Preface. Solar power can’t possibly provide power year-round, it varies far too much (Smil, V. 2017. Power Density. MIT): “Differences in monthly insolation averages depend on latitude and cloudiness: in Oslo the difference between January and June is 16-fold; in … Continue reading
