Green Utilities: Roadblocks Hit, But Renewables Ultimate Destination

Companies in Energy Intelligence's annual ranking of the top 100 green utilities and independent power producers (IPP) have added almost 100 gigawatts of new renewable capacity last year — more than they ever have. But the carbon dioxide emissions intensity of their electricity output has not been decreasing as fast as in previous years. That's because post-Covid-19 recovery caused demand to surge while adverse weather conditions — including low wind and reduced hydro availability — prevented renewable capacity from being fully utilized. This in turn caused fossil fuel-fired plants to generate more intensively. Nevertheless, the ranking's average CO2 intensity has for the first time fallen below 400 kilograms per megawatt hour, at 399 kg/MWh in 2021 — down from 405 kg/MWh in 2020 and 563 kg/MWh in 2011 when the ranking was first published.
