WHAT IS IT? The average annual decrease in carbon dioxide emissions intensity for power generation in the United States between 2001 and 2017.
Carnegie Mellon University researchers recently published a study on the topic for Environmental Research Letters. The study attributed the decline to an increase in generation powered by wind and natural gas and a decrease in coal-fired generation nationwide.
OPPD maintains a diverse generation portfolio that includes wind as well as coal and natural gas generation. In 2017, 30 percent of its generation came from renewables. When new wind projects come online in the coming years, it will put OPPD closer to its goal of at least 50 percent of retail sales coming from renewables.
