Distributed Energy

A wastewater treatment plant in the Danish city of Aarhus is reportedly producing enough power to cover all of the energy used for the whole water cycle in its catchment area—from water production and water

Solar roadways—roads that incorporate embedded photovoltaic cells—have piqued interest for several years. A few examples are finally being rolled out, though their practical applications are still being evaluated. On December 20, global transport infrastructure group Colas completed installing a solar panel paving system it calls “Wattway” (Figure 5) over 50 square meters (m2) at the […]

Beyond major reliability events that have prompted regional blackouts in the past, the U.S. grid faces “imminent danger from cyber attacks,” warns the second installation of the Obama administration’s Quadrennial Energy Review (QER). Here are other key trends outlined in the comprehensive study of the nation’s electricity system. The QER, available on the DOE web site, identifies the threats, […]

Just as the election of Donald J. Trump could result in redirected energy policy in the U.S., 2017 elections in France and Germany could reshape plans for electricity infrastructure on the European continent. Also on both continents, some factors and trends will be out of elected officials’ control. “Difficult to see. Always in motion is […]

How do you get generating company executives and those who interact with the power industry to think outside the box when planning for the future? The answer may involve a board game. Humans are pre-programmed to prefer routine, tradition, and regularity, without questioning whether longevity equals good. Fear of the unknown, and the power of […]

As our January 2017 cover image of a dynamic Rubik’s Cube suggests, the power industry, especially in the U.S., is dealing with something akin to solving a 3-D puzzle whose pieces are being added and subtracted as the game is being played. Although shares of traditional, regulated electric utilities remain some of the most predictable […]

As energy storage becomes more ubiquitous and projects grow in size and capacity, utilities of all types are exploring the best ways of putting it to use across the grid. The opportunities are large, but so are the challenges, according to a panel of executives who spoke at Energy Storage North America in October. New […]

“We’re at a very challenging time,” said former Federal Energy Regulatory Commission (FERC) Commissioner Tony Clark at the annual meeting of the National Association of Regulatory Utility Commissioners (NARUC) on November 14. We have a “need for infrastructure, but it’s more difficult to get it sited and built than ever before.” Clark’s comment, which he […]

The November 8 election yielded surprising results for controversial energy-related measures in three states. In Florida, voters rejected Amendment 1, a measure backed by utilities to curb the expansion of resident-owned solar rooftop installations. In Washington, the nation’s first state attempt to impose a carbon tax on fossil fuels and power generated from fossil fuels fell […]

Although many observers consider Elon Musk—the visionary entrepreneur who leads Tesla Motors and SpaceX—to be a disruptive force threatening the conventional power industry, he believes power companies have a bright future, if his goal to expand the use of electric cars and install vast numbers of rooftop solar systems is achieved. Speaking during a presentation […]
