Forbes updates its annual “30 Under 30” list, this time expanding the “section to include both energy and industry.”

Writes Forbes: “It’s a kind of catch-all to include young entrepreneurs that are innovating in old-school manufacturing businesses or inventing things that don’t easily fall under the ‘technology’ rubric. Regardless of whether it makes much sense to include bicycle and sneaker makers in the same subset as solar upstarts and nuclear power prodigies, that’s what we’ve done.”
