Each month, an average of 88 organizations in the U.S. transact with ENGIE for renewable energy supply. These customers are among the growing ranks who turn to ENGIE to help meet or exceed sustainability targets. With ENGIE alone, our customers can claim the environmental benefits of reducing CO2 by 1.8 million metric tons. These companies are truly “carbon champions.”

Our Greentailer® model integrates renewable generation with retail supply to create a diverse product portfolio that is designed for any stage on the low carbon journey.

Renewable energy is increasingly a lower cost per megawatt compared to other sources. The majority of newly commissioned renewable energy is more cost-effective for electricity generation than most fossil fuels worldwide, according to the International Renewable Energy Agency (IRENA). Around 91% of the utility-scale projects commissioned in 2024 were more cost effective than fossil fuel alternatives. Solar photovoltaic was 41% cheaper on average than the lowest-cost fossil fuel alternatives, such as natural gas, while onshore wind projects were 53% cheaper. The cost of battery energy storage systems has declined by 93% since 2010.
