Solar and wind energy could fulfill energy demand 10-fold, Oxford study finds::undefined
The primary finding of the study asserts that wind and solar energy have the potential to generate a staggering 2,896 terawatt-hours (TWh) of energy annually.
Yes, and most of that will be produced during summer, where our needs are at their lowest, and will therefore be wasted. The problem with solar and wind has never been production potential.

Tesla battery apparently have a density of 244-296 Wh/Kg, so does that mean 1000 metic tonnes of of batteries at 289.6 Wh would be enough to provide annual storage here? That doesn’t seem infeasible or unreasonable for something potentially so beneficial.
Lithium battery is usually not what’s is used for grid scale batteries. The new natrium batteries could do that and are made from far cheaper and more abundant materials. The energy saving concrete also promises to be a good solution when used instead of regular concrete and candy be built directly beneath renewable power plants.
