Climate change

Much has been written about renewable energy, but few stories have focused on the complexity of determining the optimal mix of solar and wind generation, and the kind and amount of energy storage, that

Braintree, MA — Competitive Power Ventures (CPV) celebrates Earth Day by announcing that more than 15 million tons of carbon dioxide (CO2) emissions have been avoided since 2011 because of the company’s new, highly-efficient electric generation facilities, which is the equivalent of removing more than 3 million cars from the road for a year. CPV […]

Legal challenges to the Trump administration’s Affordable Clean Energy (ACE) rule began in earnest April 17, as more than two dozen states and cities, along with several environmental activist groups, filed briefs with the U.S. Court of Appeals in Washington, D.C., seeking a rollback of power plant regulations that also have been decried by coal […]

The Environmental Protection Agency (EPA) on April 16 withdrew the legal justification for an Obama-era rule that required coal-fired power plants to reduce their emissions of mercury. The Mercury and Air Toxic Standards (MATS) remains in place, but Thursday’s action by the Trump administration could prevent similar regulations from being implemented in the future. EPA […]

The need to reduce carbon emissions is real. In 2018, the International Panel on Climate Change (IPCC) reported that global emissions would need to reach net-zero (or carbon-neutral) by 2050 to prevent severe climate change impacts. Electricity is a major contributor—electricity generation was responsible for approximately 33% of total CO2 emissions in the U.S. in […]

At first view, marine energy developer Minesto’s novel underwater “kite” technology may be easily dismissed as a fanciful concept, one of dozens introduced over the last decade to reap the immense ocean

While it is currently highly dependent on natural gas generation today, about 95% of ISO-New England’s (ISO-NE’s) interconnection request queue—a proposed total capacity of 20.9 GW—comprises wind, solar, and battery projects. That clearly indicates that developers in New England’s wholesale market “are looking to take advantage of state incentives, declining technology costs, and revenues from […]

Mitsubishi Hitachi Power Systems (MHPS) has bagged an order for the first advanced-class gas turbines designed to transition to renewable hydrogen fuel from Utah’s state-owned Intermountain Power Agency (IPA). MHPS’s Lake Mary, Florida–based subsidiary MHPS Americas (MHPSA) on March 10 said that the contract for two M501JAC power trains are the first in the industry […]
