New Nobel Laureates Light The Way for Smart Cities

The selection process for Nobel laureates is perhaps the most rigorous decision made on a global level. Not only does it require knowledge of a world’s worth of science and cultural advancements, but it also requires a sensitivity towards where humanity is moving as a collective people. And while energy technology companies are looking towards the philosophical “smart cities” that lie ahead, this year’s Nobel Prize awarded in Physics is reflecting the way lighting has revolutionized the world.
