So thankfully you're wrong. Society won't collapse. The prices of solar and wind are falling very rapidly and we have about a century of oil (or two) in the ground left before we'll need to start charging car batteries from the grid or producing fuel cells. Solar and wind can provide for ALL of our energy needs even if you don't take energy storage into account (you'd just have to build more plants to cover the gaps in generation caused by night time/ windless days) but WITH storage (pumped hydro, compressed air, sodium thermal) then they just generate electricity 24/7 a day anyway. Here's the worlds first big Solar Sodium Thermal Power Plant: https://en.wikipedia.org/wiki/... a 150MW plant. Costs for these types of plants are expensive now but will come down over time due to economies of scale and mass production. China already generates more power via wind than they do via Nuclear.
Here is some information on storage methods: https://en.wikipedia.org/wiki/...
Just wanted to update your information. My money's on the sodium thermal storage. Just giant containers of salt heated up and stored for when sunlight/wind is not available. Then when needed the heat from the sodium is used to boil water to turn a turbine.
