  • Smarter grids, appliances, and consumers

    More and more utilities are beginning to realize that building large power plants just to handle peak daily and seasonal demand is a very costly way of managing an electricity system. Existing electricity grids are typically a patchwork of local grids that are simultaneously inefficient, wasteful, and dysfunctional in that they often are unable, for example, to move electricity surpluses to areas ...

  • A sociotechnical systems model for smart-grid adoption in mid-sized urban environments

    In this paper, we present a quantified system dynamics model simulating the adoption of smart grid technologies such as electric vehicles, PV systems and smart meters in a mid-sized urban system and the resulting impact on the CO 2 emissions. We also analyse the impact of different subsidies on the adoption and calculate the effectiveness regarding public and private spending on these ...

  • How many negawatts do I need before I retire?

    A candy shop owner on Cape Cod offers a new approach to build a retirement portfolio: put solar panels on your roof. “We looked at the stock market last year and it didn’t look too good so we decided to invest in electricity,” said Ray Hebert, owner of Stage Stop Candy in Dennisport, in an article on wickedlocal.com by Nicole Muller. Thanks to today’s generous state and federal subsidies, Hebert ...

  • Photovoltaics Energy Technologies

    Technology Overview    Photovoltaic (or PV) cells are devices that use semiconductor materials—similar to those used in computer chips—to convert sunlight directly into electricity. The electric current can either be used immediately, or it may be stored, as in a battery, for later use. A typical PV or solar cell might be a square that measures about 4 ...

  • How much wind is needed to power a home turbine?

    First do you have what it takes? Whether you are considering a small rooftop unit or a large residential turbine you need to know how much wind power is in your area. Wind resource maps, published by the US Department of Energy show airflow speeds at 50 meters (150 feet) above the ground and are a great resource in deciding if you are in a viable location. That's great if you are installing a ...

  • 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 ...
