  • As renewable electricity is added to the grid, are power markets misfiring?

    When increasing megawatt-hours of variable solar and wind energy began coursing through the grid, the initial concern was an operational one—could grid reliability be maintained. But it turns out those megawatt-hours are creating market challenges, as well. What needs to be done to right the markets? Travis Kavulla, vice chairman of the Montana Public Service Commission, and Albert Cheung, ...

  • Study: Climate change could overwhelm U.S. electrical grid

    Climbing temperatures associated with global warming could wreak havoc on the U.S. electrical grid, according to a new study on the economic and social costs of climate change. Published last week in the scientific journal Proceedings by researchers at the University of California-Berkeley, Stanford, and University of Michigan, the study says the country will need to spend at least $180 billion ...

  • Twelve principles for introducing sustainable energy storage to the electrical grid

    Researchers have provided a set of guidelines to help policymakers, designers and operators develop sustainable solutions for energy-storage systems for electricity grids. The guidelines cover a range of energy-storage technologies and grid-integration options. As societies move towards decarbonising the world’s energy supply and reducing greenhouse gas emissions, energy storage is ...

  • Study of different carbon materials for their use as bioanodes in microbial fuel cells

    Microbial fuel cells (MFCs) are capable of removing the organic matter contained in water while generating a certain amount of electrical power at the same time. One of the most important aspects in the operation of MFCs is the formation of biofilms on the anode. Here, we report the characterization of different carbon electrodes and biofilm using a rapid and easy methodology for the growth of ...

  • What will it take to integrate renewables into the power grid? Ask a bicyclist.

    When it comes to fitting into the current system, bike commuters and electrons have a lot in common. There’s nothing quite like biking down clogged city streets, weaving in and out of traffic. For short distances, it’s faster than driving. It’s liberating. It’s fun. It also makes it painfully clear that most roads ...

  • The Economics of Grid defection

    Distributed electricity generation, especially solar PV, is rapidly spreading and getting much cheaper. Distributed electricity storage is doing the same, thanks largely to mass production of batteries for electric vehicles. Solar power is already starting to erode some utilities' sales and revenues. But what happens when solar and batteries join forces? Together they can make the electric grid ...
