The legislation aims to […]

China is preparing to expand nationwide a ban on new coal plant construction announced in April in an attempt to further rein in overcapacity and boost utilization of renewable energy, according to a report in Australian Financial Review. This spring, China’s National Development and Reform Commission and National Energy Administration suspended or slowed plans for […]

The “polar vortex” storm of January 2014 blew in big changes to PJM Interconnection’s operations. But these changes are now the subject of a lawsuit filed by environmental groups, alleging they discriminate against clean energy sources. The sub-zero temperatures froze coal piles and gearboxes. Natural gas plants, lacking firm contracts for fuel delivery, were unable […]

Many operators are perfectly happy with their trusty red and green HMIs and can’t imagine why they should give them up for a dull greyscale display. When they take a closer look, they usually find out that grey is beautiful.

Siemens on July 5 entered the competition for the largest wind turbine in the world with an upgrade of its SWT-7.0-154 model. The new SWT-8.0-154 turbine boosts power output over the earlier model through upgraded magnet technology. Other components remain largely the same over the earlier model and the smaller SWT-6.0-154 turbine, Siemens said. The […]

Renewable generation is usually characterized as more environmentally friendly than fossil fuels, and in many respects, that’s true. But there is a growing recognition that solar and wind generation have their own impacts, and an increasing number of manufacturers and generators are looking for ways to minimize them. Iceland might be about the last place […]

Lake Kivu, the 1,040-square-mile “killer lake” that stretches over the border between Rwanda and the Democratic Republic of Congo (DRC), has long been a source of trepidation. Because it sits between two

Fortum Värme, a company jointly owned by Finnish energy firm Fortum and the city of Stockholm on May 9 inaugurated a new biomass-fired combined heat and power (CHP) plant on the shores of Värtan, a strait in Sweden’s capital city.

Projections that coal utilization will decline faster than previously forecast have spurred Babcock & Wilcox Enterprises (B&W) to shed 200 jobs and restructure its traditional power business that serves coal-fired power generation in a bid to reduce overhead and improve efficiency. The Charlotte, N.C.–based energy and environmental technology and service company said on June 28 […]

The world’s power sector last year emitted a third of global sulfur dioxide (SO2) emissions, 14% of nitrogen oxides (NOx), and 5% of total particulate emissions (PM2.5), but those emission values have fallen drastically over the last decade even though coal power generation has seen a surge, the International Energy Agency (IEA) said in a […]

The U.S., Mexico, and Canada today announced an unprecedented goal to procure 50% of North America’s total power generation from renewables, nuclear, carbon capture and storage (CCS), and energy efficiency technologies by 2025. President Obama, Prime Minister of Canada Justin Trudeau, and the President of Mexico Enrique Peña Nieto, announced the continental goal, part of […]

Although it’s not widely publicized, a majority of the energy used to generate electricity is wasted in the form of heat discharged to the environment. For better or worse, that’s just the way a typical thermal power plant works. Fuel, such as coal, biomass, natural gas, or uranium (in the case of nuclear plants), is […]

Enrico Viale, head of global thermal generation for the Italian energy company Enel, kicked off an international power industry event yesterday with a keynote presentation describing the “needs” of utilities in the future.

Diablo Canyon, the two-reactor nuclear power plant on the central California coastline, will be permanently shuttered by 2025 under a renewables-boosting initiative announced today by its owner, Pacific Gas and Electric (PG&E). The company on June 21 unveiled a “joint proposal” with labor and environmental groups that seeks to increase investment in energy efficiency, energy […]

  The Environmental Protection Agency (EPA) has unveiled details of the Clean Energy Incentive Program (CEIP), a voluntary measure central to the judicially stalled Clean Power Plan that seeks to provide guidance to states and tribes that want to meet goals under the plan when it becomes effective. The final Clean Power Plan, finalized in […]

The importance of RTO maintenance
RTOs or Regenerative Thermal Oxidizers control emissions without producing harmful byproducts or hazardous waste. They help destroy volatile organic compounds (VOCs), hazardous air pollutants (HAPs) and other odorous emissions created during normal manufacturing and industrial processes by combusting them into carbon dioxide and water. RTOs pass hot exhaust gas and cooler

Panels at the 2016 Edison Electric Institute convention focused on technologies and policies at what’s often called the “grid edge.”

The Minnesota Public Utilities Commission (MPUC) approved Minnesota Power Co.’s integrated resource plan (IRP) on June 9, which calls for the economic idling of the company’s Taconite Harbor Energy Center—a two-unit 150-MW facility (Unit 3 was retired in June 2015)—this fall and ceasing coal operations at the site in 2020. The MPUC also adjusted the […]

  Even though it may dominate forecasts, natural gas–fired generation faces a troubled expansion in the U.S., according to experts from a variety of stake-holding entities—including an industry group, a utility, a generator, and a pipeline company. Challenges that have few solutions—from price volatility, to gas transport concerns, to rule uncertainty—may upend the nation’s dependence […]

China unveiled its 13th Five-Year Plan this March. The official proposal that will guide the country’s economic and social development from 2016 through 2020 lays out targets and other measures to address a number of climate change, air pollution, and water policies that will build on progress to transform its power sector. The plan sets […]

It’s axiomatic that state governments believe they can manage their own affairs better than the federal government. But our system reserves certain bailiwicks for federal oversight, and one of those is the

Plans are under way to install a pilot 1-MWh lithium battery–based storage system in 2018 at the world’s first floating wind farm in Aberdeenshire, Scotland. The “Batwind” system, to be installed at

The two probable major-party U.S. presidential candidates hold very different views on energy and climate. One intends to focus on expanding and developing America’s fossil-fuel industries, while the other plans to grow renewable energy and promote efficiency. Can you guess who’s who? Fossil vs. Renewable Donald Trump, the presumed Republican nominee, presented his “America-First Energy […]

The Environmental Protection Agency (EPA) must halt its drive to help states supportive of the Clean Power Plan to comply with the rule because it defies the Supreme Court stay, the attorneys general for West Virginia and Texas have urged the agency. An April 28 request to the agency by 14 states seeking technical assistance […]

Misaligned mirrors at the Ivanpah Solar Electric Generating System in California caused electrical cables to catch fire about two-thirds of the way up the Unit 3 tower on May 19, according to several media reports of statements attributed to fire department personnel.

Even if the final Clean Power Plan is not implemented, U.S. electricity-related carbon dioxide (CO2) emissions will remain well below 2005 levels, the Energy Information Administration (EIA) said in a comparison of two cases looking forward through 2040. The cases are part of the agency’s May 17–released Annual Energy Outlook 2016 Early Release (AEO2016 Early […]

The world’s frenzied economic growth through 2040 won’t be matched by electricity demand growth, the Energy Information Administration (EIA) says in the International Energy Outlook 2016 (IEO2016 ) released on May 11. World net electricity generation will jump 69% by 2040, the IEO2016 reference case projects, but that is still well below “what it would […]

Hands down, 2015 was a record year for global investment in renewable energy. Excluding large hydroelectric projects, the amount of money committed to renewables rose 5%, to $285.9 billion, exceeding the previous record of $278.5 billion reached in 2011.

Taking full advantage of the international political thaw with Iran, Germany has begun working closely with the fossil fuel–rich nation to develop renewable energy strategies based on the successes and failures its policymakers have learned from its own Energiewende (energy transition). To jumpstart this, Germany’s government recently released a commissioned report titled “Enabling PV Iran,” […]
