NYSE to purchase renewable energy certificates from Constellation subsidiary

The New York Stock Exchange will purchase renewable electricity certificates from a Constellation Energy subsidiary, the company announced Wednesday.

Constellation NewEnergy Inc. will produce wind energy at certified facilities in the United States to match the approximately 28 million kilowatt-hours used annually by the stock exchange, according to the announcement.

By supporting this renewable source of electric power generation, which will displace generation using conventional fuels, the exchange will avoid production of more than 57 million pounds of carbon dioxide emissions.

An earlier version of this article misstated the amount of energy the stock exchange uses annually. The Baltimore Sun regrets the error.
