InfographicsThe EPA’s Clean Power Rule in Three Infographics
Under rules proposed by the Environmental Protection Agency (EPA) on June 2, 2014, existing fossil fuel–fired U.S. power plants must comply with state-specific goals to lower carbon pollution from the power sector by 2030, while modified and reconstructed power plants will be subject to technology-based performance standards. The EPA’s “Clean Power Plan” rule affecting existing […]

Power British Columbia
British Columbia (BC) has long enjoyed some of the lowest electricity costs in North America, but when in August 2013, a draft of the BC Rates Plan which proposed a 26% rate increase by 2016, was leaked, this was met with such a backlash of protest that the government was forced to reconsider the proposal.

RenewablesRWE’s Thomas Birr on Corporate Strategy in a Changing German Electricity Ecosystem
RWE AG is Europe’s third-largest electricity and fifth-largest gas marketer, with holdings in upstream oil and gas production, power grids, and energy trading. Its German power subsidiary has been the utility poster child for the effects of the Energiewende, the transformation of the Germany power system away from nuclear and coal toward renewable energy and […]

RenewablesThe EEI’s Campaign for Electric Utility Industry Supremacy
At the Edison Electric Institute (EEI) annual meeting this week in Las Vegas, the tone was one of collaboration with partners from Washington to distributed generation companies. Those partnerships will be needed as the investor-owned utility (IOU) industry fights not so much a war on coal as a war for mindshare and wallet share in […]

Nest Thermostats: The Future of Demand Response Programs?
Sure, the Nest Learning Thermostat is smart, user-friendly, and downright sexy, but at $249, it’s more a luxury item than a mass-market appliance. Indeed, Nest thermostats are highlighted in upscale real estate listings alongside marble countertops and stainless steel appliances. Although Nest has done well since its debut in 2011, with almost a million units […]

EnvironmentalCombined Mercury and SO3 Removal Using SBS Injection
Though no single mercury capture approach is best for all plants, when you can capture two (or more) pollutants with one sorbent, it’s worth a careful look. The U.S. Environmental Protection Agency’s (EPA’s) Utility Mercury and Air Toxics Standards (MATS) regulation requires power plants to reduce emissions of hazardous air pollutants (HAPs), including mercury. The […]

O&MLatest Electromagnetic Technology Device Improves Inspection Accuracy and Repeatability
Eddy currents are electrical currents induced within conductors by changing magnetic fields. They are commonly used in nondestructive evaluation (NDE) and corrosion monitoring of structures with painted surfaces. The work of eddy current technicians, who specialize in the electromagnetic modality, requires a high degree of accuracy even when working under challenging testing conditions. Traditionally, technicians relied on […]

Legal & RegulatoryBiomass Exemption Sails into the Sunset
With quickly approaching deadlines for achieving renewable portfolio standard goals, the likely lapse of a critical exemption this month may increase the challenges for meeting those mandates. Approximately four years ago the U.S. Environmental Protection Agency (EPA) took the first step in regulating greenhouse gas (GHG) emissions from electric generating units (EGUs) by promulgating the […]

EnvironmentalIs Your Plant Ready for MATS?
It has been more than two and a half years since the Environmental Protection Agency (EPA) issued national emission standards for hazardous air pollutants from coal- and oil-fired electric utility steam generating units (EGUs), and standards of performance for fossil fuel–fired electric utility, industrial/commercial/institutional, and small industrial/commercial/institutional steam generating units. Specifically, the rule created mercury […]

WaterThe Water-Energy Nexus Takes Center Stage
Power plant operators have long understood the vital role water plays in power generation. Now, as the rest of the world begins recognizing that as well, a conflict is brewing between the growing demand for electricity and increasingly strained water resources. Unless you’ve been living in a cave, you’ve likely heard the term “water-energy nexus” […]

RenewablesShifting Sands: The Middle East’s Thrust for Sustainability
Economic and population booms forecast for several countries in the oil- and gas-rich Middle East are forcing a reassessment of those countries’ historic reliance on fossil fuels and a new focus on securing sustainable electricity and water supplies. The Middle East is a region of extremes. While some countries enjoy opulent wealth, others are some […]

EnvironmentalGeoengineering: A Practical Climate Work-Around or Just Plain Crazy?
Faced with roadblocks to reducing greenhouse gas emissions via globally meaningful regulations or carbon pricing schemes, some scientists say it’s time to consider even more drastic human intervention. As it looks increasingly unlikely that the world will adopt a political and economic approach to reducing greenhouse gas emissions—primarily carbon dioxide—what was once regarded as a […]

Distributed EnergyBlurring the Line Between Temporary and Permanent Power
Temporary power may be the most widely distributed “distributed” generation worldwide, and its distribution is spreading, thanks to its ability to quickly meet urgent needs not only for event, construction, and post-disaster emergency power but also for fast-growing economies and stressed grids. That’s making it a serious competitor for “permanent” power in some situations. When […]

CoalDoes IGCC Have a Future?
Once touted as the savior of coal power and the future of clean coal generation, integrated gasification combined cycle (IGCC) technology has seen its prospects swamped by soaring costs and technological challenges. Though it remains controversial, its proponents are not ready to give up. If you’re an energy sector observer with an interest in integrated […]

As Clean Energy Accelerates, a New Era of Choice Is Upon Us
Though our current power grid is more sophisticated and reliable than when Thomas Edison designed it nearly a century ago, it uses the same model: A company burns fuel to create electricity, which is then sent hundreds of miles along inefficient wires to customers who are given a single energy choice: on or off. Now, […]

The world’s first floating wind turbine array could be installed offshore of northeast Scotland by 2017 if a project recently unveiled by Kincardine Offshore Windfarm Ltd. proceeds as planned. The joint project between Pilot Offshore Renewables and the construction giant Atkins entails the installation of eight turbines on semi-submersible platforms about 8 miles off the […]

Last year, the U.S. exported nearly twice the amount of wood pellets it sent overseas in 2012—and almost all of it went to Europe for heat and power needs. This trend has gained momentum since 2009, when the European Commission (EC) enacted its 2020 climate and energy package, and will possibly continue in the long […]
