On April 27, the U.S. saw yet another significant milestone for its so-far nonexistent offshore wind sector as Deepwater Wind broke ground on the Block Island Wind Farm in Rhode Island. The company says that the five-turbine 30-MW wind farm will produce enough electricity to power all of the island’s homes and businesses when it […]

The installation of more than one million solar photovoltaic (PV) modules at Sempra U.S. Gas and Power’s and Consolidated Edison Development’s 250-MW AC Copper Mountain Solar 3 project in Boulder City, Nev., was completed in early April. Cupertino Electric and Amec Foster Wheeler said on April 6 that the last module was put in place […]

Despite plunging oil prices, 2014 was a formidable year for renewables, according to two reports released in early 2015. According to the “Global Trends in Renewable Energy Investment 2015”—the annual report prepared by the United Nations Environment Programme (UNEP), the Frankfurt School-UNEP Collaborating Centre for Climate & Sustainable Energy Finance, and Bloomberg New Energy Finance—energy investments […]

“You can’t take a clean source of energy off the table.” That was the conclusion that a panel of four experts came to as they discussed the role that nuclear power should play in the battle to fight climate change. The panelists met on May 14 as part of the 62nd Annual Industry Conference and […]

Biomass combustion should not be an approved compliance method under the Clean Power Plant because burning trees is not carbon neutral, both senators from Massachusetts told the Environmental Protection Agency (EPA) on Friday. In a letter to EPA Administrator Gina McCarthy, Sens. Ed Markey (D-Mass.) and Elizabeth Warren (D-Mass) said that treating bioenergy as having […]

An interdisciplinary study led by the Massachusetts Institute of Technology (MIT) Energy Initiative concludes, among other things, that “state renewable portfolio standard (RPS) requirements should be replaced by a uniform nationwide program.” The report—released on May 5—focuses on the future of solar energy, suggesting that a massive expansion in solar capacity to “multi-terawatt scale” is […]

The Egypt Economic Development Conference (EEDC) in Sharm El-Sheikh resulted in some big agreements for the Egyptian government, including a reported $10.5 billion deal with Siemens and a $1.7 billion order with GE. The conference was held March 13–15, 2015, and was touted as a key milestone of the government’s medium-term economic development plan, which […]

In the UK, which has the world’s largest offshore wind capacity, in large part due to government backing, formal negotiations have begun on public funding of a £1 billion ($1.48 billion) tidal lagoon project to produce electricity from turbines in Swansea Bay, South Wales. The 320-MW project (Figure 3)—which could be the first of its […]

The life of a wind turbine can be pretty precarious. The blades—made of laminated materials, such as composites, balsa wood, carbon fiber, and fiberglass—can reach speeds up to 180 miles per hour at the tip, which means even small particles in the air can cause damage to the surfaces. It’s probably no surprise that lightning […]

The digital economy has changed the way we shop for clothing, travel, communicate with friends and family, consume news, and watch television—among so many other things. But the innovative potential of the digital economy has not yet found a place within the electric system. With that important goal in mind, New York has embarked on […]
