Green Apple: Empire State Building now powered by wind
The world got a little bit greener when the lights of the Empire
State Building flickered to life this year: For the first time, the beloved skyscraper and 13 other office buildings owned by the same company were powered solely by wind.
Empire State Realty Trust’s announcement of a major purchase of wind power from Green Mountain Energy and Direct Energy makes it the nation’s biggest real estate user of entirely renewable energy.
The three-year contracts, which started Jan. 1, will provide an estimated 300 million kilowatt hours of electricity for ESRT’s more than 10 million-square-foot portfolio. That’s enough to light every home in New York state for a month.
The commercial real estate agency has already established a reputation for sustainability: A decadelong “deep carbon” retrofit enabled the Empire State Building to cut its planet-warming emissions by about 40 percent. The skyscraper itself has run on renewable energy since 2011.
By expanding its renewable energy commitments to its entire portfolio, ESRT will avoid the production of some 450 million pounds of carbon dioxide, the equivalent of removing all New York City taxis from the road for an entire year.
The energy needed to operate buildings is among the nation’s largest sources of greenhouse gas emissions. In New York, buildings generate more than two-thirds of the city’s carbon emissions.
“More and more building owners are understanding the critical role that our skyline plays in tackling climate change and how they can be an important part of the solution,” said Donna De Costanzo, a director for climate and clean energy at the Natural Resources Defense Council.
After the Empire State Building’s “nation-leading retrofit,” she said, the decision to meet its remaining energy needs with renewables is “a significant next step.”
Citing confidentiality clauses in its contracts, ESRT declined to give the dollar value of the renewable energy purchase. The company noted that buying clean energy is slightly more costly than simply buying power from local utilities.
But opting for renewable power was as much a business decision as an environmental one, said Anthony Malkin, the trust’s chief executive. Many of ESRT’s existing tenants had been asking about switching to greener energy sources. And a growing number of companies — including some that rent space in ESRT buildings have adopted corporate sustainability initiatives that include commitments to reduce their carbon footprints.
“We want to differentiate ourselves so we get better tenants at higher rents so we can outperform our competition,” Malkin said.
“It’s all market driven.”
This move is an important symbolic victory for renewables, said Cyndy Reynolds, commercial sales director for Green Mountain Energy.
“When you have someone like ESRT who you know is going to look at every facet, whether it’s cost or reliability, and they decide to move forward . . . it’s not just a PR play at that point,” Reynolds said. “It truly does check the boxes of all the business metrics they have.”
The realities of the U.S. electric grid mean that the electrons powering ESRT’s lights and elevators don’t necessarily come directly from renewable sources. Green Mountain Energy sells power from certified wind farms around the country. Purchases of renewables through Direct Energy go toward solar and wind facilities in Texas.
