Alright, now we agree: solar isn't for everywhere, and the gravity storage method won't work in most places. You need preexisting slope, and my original comment was highly US-normative. As such, yes, we would need huge swathes of solar and wind collection sites, passive wave generators, pumped hydro and, yes, perhaps nuclear. Not everything will be "on" all the time. As far as the energy vs. Electricity numbers, while I vacillated between different terms, I WAS quite careful to only include electricity numbers throughout my stats and, again, none of my points were trying to prove that solar, specifically, is the right answer for the netherlands in exclusion of all else, but only that a significant energy storage problem can be solved with gravitational potential, and that the solution IS scalable if sites are selected carefully, and the fact that this has not been tried at scale anywhere in the world is due to government corruption. Still a US-normative idea, which I'll grant, but still true, when you have places from morocco to the Gobi, to the outback to the western US, all with significant natural elevation change, significant open areas, and excellent prospects for renewable energy sources of ALL kinds.

Also, as far as solar panels go, remember that actual diode solar panels are NOT the only way to harvest solar energy (let alone the cheapest). Mirrors can easily be used to boil water, and this plan was nearly attempted throughout egypt a hundred years ago (see Frank Shuman's solar thermal generators). However, I'm not about to argue that we should put giant solar collectors in one of the countries that is simultaneously the most population-dense (3rd highest in europe, IIRC) AND in a climate where large-scale solar is somewhat inefficient, ESPECIALLY when you have so much available wind power.
