The world’s first wind farms are reaching the end of their expected lifetimes. As they become outdated, or just inefficient, many developers are considering repowering. Here’s a look at where repowering activity is happening the most and why. Since the world’s first wind turbine used to convert wind energy into electricity was built by Professor […]

The U.S. Department of Agriculture (USDA) announced it will provide $3.6 billion in loans to fund 82 projects in 31 states to finance new transmission and distribution lines, smart grid technologies, renewable projects, environmental improvements, and energy efficiency. The agency said on October 26 that the loans will be provided through the Electric Program of […]

Nuclear power’s future—and its much-needed contribution to U.S. decarbonization efforts—may be hampered if eight pressing issues aren’t addressed within the next five years, U.S. Energy Secretary Ernest Moniz said at a recent event held at the Center for Strategic and International Studies. The issues Moniz outlined in his keynote speech at a six-hour event titled […]

The Minnesota Public Utilities Commission (MPUC) voted unanimously to support Xcel Energy’s latest long-range plan, which will transform the company’s energy fleet. Xcel expects to more than double its renewable energy portfolio as a result, delivering greater than 60% carbon-free energy to its Upper Midwest (Michigan, Minnesota, North Dakota, South Dakota, and Wisconsin) customers by […]

Dreams of a future of round-the-clock dispatchable solar energy may have become reality at the Crescent Dunes Solar Energy Project in Nevada.

Brazil’s environmental protection agency, IBAMA, in early August canceled development permits for an 8-GW hydroelectric project on concerns about its social and ecological impacts. If built as proposed by a consortium of multinational companies—including Brazilian parastatal Eletrobras and private sector partners GDF Suez/Engie, EDF, Camargo Correa, Neoenergia, COPEL, and Endesa Brasil—the São Luiz do Tapajós […]

One of the world’s first offshore tidal energy arrays was connected to Scotland’s grid this August. On its heels is the grid connection of a second array that is owned by a different company. Nova Innovation, a Scottish tidal energy company founded in 2010, on August 28 grid-connected the second of three 100-kW Nova M100 […]

New York City is aiming to have 100 MWh of energy storage by 2020 under an unprecedented target set by Mayor Bill de Blasio on September 23. The city’s first-ever energy storage deployment target will help reduce reliance on the grid by making variable sources of energy production, such as solar panels, usable for more […]

Oral arguments on the merits of the Environmental Protection Agency’s (EPA’s) Clean Power Plan were concluded before an en banc panel (10 judges, rather than the anticipated three) at the D.C. Circuit Court of Appeals on September 27. West Virginia v. Environmental Protection Agency (No. 15-1363) is arguably the most important environmental case in nearly […]

Global resources of variable renewable energy—primarily wind and solar—despite breakneck growth over the past two decades, are beginning to run up against technological and policy limitations on further deployment, and future growth will depend on significant changes in policy and grid design, according to a new report. Released on September 20, Variable Renewable Energy Sources […]
