A new report from the U.S. Environmental Protection Agency (EPA) is giving Washington D.C. (and a few other cities) a reason to pat itself on the back.

That’s because the city has 480 Energy Star-certified commercial buildings, more than any other in the nation. The EPA loosely defined Energy Star buildings as those that are more energy efficient than 75 percent of other similar buildings in the nation— an average of 35 percent more energy efficient.

With 35 percent greater efficiency comes an approximately 35 percent reduction in greenhouse gas emissions, the major drivers of climate change.

“Since 1999, more than 25,000 buildings across America have earned EPA’s Energy Star certification, saving nearly $3.4 billion on utility bills and preventing greenhouse gas emissions equal to the emissions from the annual electricity use of nearly 2.4 million homes,” wrote Jean Lupinacci, director of the Climate Protection Partnerships Division of the EPA.

To correspond with the release of their new ranking, the EPA released the following infographic which, shamefully, shows San Diego (our hometown) in 17th place. Better luck next year, guys.

Drax advances biomass strategy with Pinnacle acquisition

Drax is advancing biomass following Pinnacle acquisition it reported in a trading update

Drax' recently completed acquisition of Pinnacle more than doubles its sustainable biomass production capacity and significantly reduces its cost of production, it reported in a trading update.

The Group’s enlarged supply chain will have access to 4.9 million tonnes of operational capacity from 2022. Of this total, 2.9 million tonnes are available for Drax’s self-supply requirements in 2022, which will rise to 3.4 million tonnes in 2027.

The £424 million acquisition of the Canadian biomass pellet producer supports Drax' ambition to be carbon negative by 2030, using bioenergy with carbon capture and storage (BECCS) and will make a "significant contribution" in the UK cutting emissions by 78% by 2035 (click here).

Drax CEO Will Gardiner said its Q1 performance had been "robust", supported by the sale of Drax Generation Enterprise, which holds four CCGT power stations, to VPI Generation.

This summer Drax will undertake maintenance on its CfD(2) biomass unit, including a high-pressure turbine upgrade to reduce maintenance costs and improve thermal efficiency, contributing to lower generation costs for Drax Power Station.

In March, Drax secured Capacity Market agreements for its hydro and pumped storage assets worth around £10 million for delivery October 2024-September 2025.

The limitations on BECCS are not technology but supply, with every gigatonne of CO2 stored per year requiring approximately 30-40 million hectares of BECCS feedstock, according to the Global CCS Institute. Nonetheless, BECCS should be seen as an essential complement to the required, wide-scale deployment of CCS to meet climate change targets, it concludes.
