Innovations in energy storage, smart grid, and electricity generation technologies will affect every part of the source-to-consumer supply chain for powering the planet. Energy storage tech improves the viabilities of wind and solar power--two energy sources that remain cost prohibitive due to expenses related to batteries that would store generated energy. Smart grids will regulate the movement of energy throughout a city or state, insuring the areas from crippling blackouts. Developments in electricity generation make sure we make the most out of fossil fuels and other energy sources to improve efficiency.
