This is the worst argument I've ever read for renewables.
With renewable and storage, you need to build at the very least 7 times the capacity. Maybe as much as 40 times the capacity. Because of the low load factor, the fact that it's pretty common to have a full week without wind or without sun, etc.

Also, wave energy converters like Pelamis are an exciting technology, precisely because they harvest wind energy decoupled in space and time. It is a great opportunity for Scotland, the coast of France and Spain, Japan, Scandinavia and so on. Not totally technologically mature but shown to be viable using 400kW plants. https://www.youtube.com/watch?v=l3-SXFtPYe0 https://www.youtube.com/watch?v=l3-SXFtPYe0 https://www.youtube.com/watch?v=slawyq4PXxE https://www.youtube.com/watch?v=slawyq4PXxE This is so fantastic. Makes my heart jump.
