What's the best energy company?

This really depends on what state you live in, your household's particular energy usage needs, and what you value. It's best to compare your options from multiple retailers, particularly as the industry continues to evolve and new offers enter the market. Don't forget, being larger in size doesn't automatically mean the 'best' or cheapest deals.
