Comment A breakthrough in energy storage is badly needed (Score 1) 338
Renewable energy has made stunning advancements in the time I've been a Slashdot reader. In the early 2000s a situation like this seemed utterly impossible within my lifetime. Now here we are 20 years later with sometimes too much renewable energy on hand. It's amazing.
I think it's only getting more and more obvious now that for renewables to really take over steady/dependable energy generation duty, some affordable and dependable method of reliably storing excess energy during sunny or windy days needs to be achieved.
