Our ability to generate, store, and utilize DC electricity locally from clean and sustainable energy sources without the need for long-range transmission and distribution system enables the possibility for transformational changes in the electric utility and transportation infrastructures. The use of DC electricity enhances system-wide efficiency and reduces the overall cost. DC and hybrid microgrids powered by distributed clean energy sources such as wind and solar PV systems can rapidly contribute to human development around the world, and especially in emerging economies. Likewise, electric vehicles powered with clean energy technologies have the potential to dramatically impact the impending global climate changes.
