How Duya ‘Run The World’ on Solar + Wind?

Answer, from this article: ENERGY STORAGE.

Yes, EleBlog is the place that declared 2011 “the year of energy storage.” Well, it appears that might have been RIGHT, but a bit early.

Here’s what the piece says (among other things):

Batteries comprise an enormous global market, and are often used in personal solar systems to provide power at night. But batteries are seldom used to back up power plants because they have low energy density, are expensive, and have a limited lifespan. However, a great deal of research is being devoted to the development of advanced batteries, which are projected to reach gigawatt levels of utility-scale storage over the next 10 years.

Governments are investing heavily in the development of utility-scale storage, and a number of utility-scale storage possibilities are still in development. This is an area that promises to grow rapidly in the coming years given the number of countries implementing aggressive renewable electricity standards.
