The editors at Inc. magazine have released their rankings of the 5,000 fastest-growing companies in America. The list offers an interesting snapshot of where growth is taking place in the energy sector.
The boom in America's unconventional oil and gas development is clearly evident on the list. Out of the 110 energy companies mentioned, there were dozens of firms providing drilling services, pipeline construction services, and consulting on fossil energy development. With the U.S. now producing more liquid fuels than Saudi Arabia, the growth of those companies isn't surprising.
But with renewable electricity doubling over the last four years and more states getting serious about using efficiency as a resource, the clean energy sector was also very well represented. Inc. identified 45 companies offering demand response, energy efficiency andsolaras part of the list.
