Can you share what is your storage solution that will be needed to make renewables without coal and gas practical? Where can I see storage handling gigawatthour

  I have read in theglobeandmail forums comments from some people who think that building battery parks is a great idea, and that it is a huge oversight that solar + batteries aren't pushed as the final solution to all energy needs in Canada. And they seem as sincere as they are earnest. It is very hard to argue with that logic. Where do we start? Just saying batteries are really expensive doesn't reach people who want a perfect magic solution.

    I mean batteries might work! My problems with that approach is that: 1) Batteries are in everything. If we want to go from fossil fuels to renewables + batteries, at the same time as we go from ICE cars to BEVs, that's going to be a lot of batteries. Does the world have enough raw materials and batteries to do that? Back of the envelope: My country consumes 77 TWh yearly or about 212 GWh per day (assuming it is evenly distributed). To cover day-to-night cycle, would we need 100 to 150 GWh of batteries? That's a lot of batteries (seem like yearly production of whole world but I can't find good source) and 10 % of our GDP in current battery prices. 2) If we're saying "renewables are cheaper", are we really adding the cost of storage?
