About Green Mountain Energy

The honest take.

Green Mountain Energy was the first retail electricity provider in the US to offer 100% renewable energy to consumers. Every plan they sell is 100% wind and solar. They're now owned by NRG Energy but continue to operate as a standalone green-focused brand. Prices are typically 5–15% higher than the cheapest plans in Texas because of the renewable premium, but Voltcheckr ranks them against non-green plans so you know exactly how much the green premium costs at your usage.
