 While fuel switching may be the easiest option for hitting the 2020 and 2030 goals set by the Environmental Protection Agency’s (EPA’s) proposed Clean Power Plan, it may impede reaching longer-term climate targets said experts at an April 8 symposium hosted by the Central Texas Association for Energy Economics and the Energy Institute at the […]

A Gallup poll completed last month found that only 32% of adults in the U.S. worry a “great deal” about global warming or climate change, while 45% worry “only a little” or “not at all.” The survey was taken via telephone interviews conducted during the first week of March using a random sample of 1,025 […]

Everyone loves efficiencies. Combining generation technologies can create a plant that’s more than the sum of its parts, but engineering challenges mean these projects are not for the faint of heart. When you think of “hybrids” these days, your first thought is probably of automobiles. But hybrids—hybrid power plants, that is—are starting to emerge in […]

It’s been called “filling the duck pond,” and it’s the increasingly common challenge worldwide of balancing supply and demand when variable renewables are not feeding power to the grid. Gas-fired generation is often filling the pond, but the technology mix matters. The growing portfolio of renewable power generation around the world has made the selection […]

The ongoing record drought in California has caused significant changes in the state’s power mix as water available for hydroelectric generation becomes increasingly scarce, according to a recent report from Oakland-based nonprofit the Pacific Institute.
