Based on current trends in solar energy adoption across the world, analysts at Bloomberg New Energy Finance estimate that of the 238 million new households with access to electricity set to form between now and 2030, 72 million will use solar home systems, while 34 million will benefit from microgrids and decentralized energy systems.

Access to cheap, sustainable energy stands to benefit not only those transitioning away from traditional energy sources, but developing or rural communities that have had little to no access to electricity. About 1.2 billion people, or 16% of the world’s population, still have little to no electricity at all, and some 700 million will still be without power by 2030 if decentralized grids do not expand.

"Decentralized systems, including those powered by renewables, could and should close the gap in an environmentally sustainable way. In fact, they estimate that the total industry investment required to achieve this is approximately $372 billion dollars less than recent assessments by the International Energy Agency,” the report says.
