(26,549 posts)We also have to invent some new technologies.
For example, grid-scale batteries aren't feasible with current battery technologies. Not due to price, but because we'd have to use a very large portion of all of the world's raw materials to make enough batteries.
Using pumped hydro for grid-scale storage runs into the problem of not having enough space in places with sufficient elevation difference to power the entire grid.
And this is ignoring the problems in transferring the power from the sunny parts of the country to the cloudy parts of the country - you need a lot more capacity in the sunny parts to overcome the resistance in 2,000-mile long wires...unless we invent warm superconductors.
None of these are easy problems to solve, where simply throwing more money at scientists will quickly result in new inventions.
