The rechargeable battery has upended the middle east expectation with his innovative idea for an electric utility that would centrally power homes and industry. How far and fast they go, will depend both on the rate at which the economics of renewables improve and on the advance of technologies ranging from lead-acid to lithium-ion. Interestingly, an enlargement of the battery industry is to store power when renewables such as wind and solar power are. What’s driving this growth isn’t really a secret and customers around the world have become more aware of and interested in sustainability issues.
