  • Utilities: friend or foe of energy efficiency?

    With oil prices so high, talk again has turned to making the U.S. more energy efficient. In the power industry, utilities have been typically charged with this mission. Or to more aptly describe it, they have gotten dragged, kicking and screaming, into helping their customers use less electricity. You can’t blame them for resisting. An electric utility is a business that makes its money ...

  • Export opportunity for US energy efficiency?

    For a long time the energy efficiency industry operated largely under the two-guys-and-a-truck-model: local businesses made up of small contractors. Then the ‘super’ energy efficiency service companies (ESCOs) emerged, big operations taking on big contracts often for government, schools or hospitals, like the $35 million deal that Pepco Energy Services signed with the Prince ...

  • Energy Efficiency prospects: What to watch

    Events unfolding in two US Northeast states – New York and Massachusetts – signal increased business opportunity for energy efficiency companies, green architects, lighting contractors, smart grid innovators and others in the business of saving energy. First, the energy efficiency world should keep an eye on debate over the possible shutdown of the Indian Point nuclear power plant in ...

  • How to make energy efficiency affordable

    Energy efficiency is a tortoise in the green energy race. Not glamorous like solar, wind or smart grid, it tends to plod along in the back of the pack, attracting little media attention. But being last can be a good thing; you learn from the frontrunners. Such is the case when it comes to financing. EE is beginning to borrow from strategies that have spurred tremendous growth for solar and other ...

  • Energy Efficiency and PV: Together Forever

    We have seen a marriage of the energy efficiency and solar energy industries as the US has worked to green its buildings. In fact, some financing programs require that all cost-effective efficiency be pursued before solar panels are installed.  Here Elisa Wood interviews Liz Merry, owner of Verve Solar Consulting, about how the solar industry views energy efficiency and the outlook for ...

  • Case study - Multi-tenant building energy efficiency

    Buildings accounted for roughly 40% of total U.S. energy consumption in 2010, according to the United States Energy Information Association. “[New York] City's roughly 1 million buildings cost $15 billion a year to power and heat and account for 80% of the city's greenhouse gas emissions”(1). The proliferation of smart energy devices and building management systems will result in the ...

  • Energy efficiency: Big deals and new ideas

    The economic premise behind energy efficiency –  that it’s cheaper to save a unit of energy than to make one – has caught on in the US.  Energy efficiency spending is up, and our energy use is declining, measured both per capita and per dollar of gross domestic product, according to government ...

  • Energy Efficient Products: the case of Latin America

    Companies manufacturing and selling appliances, equipment and lighting in Latin America (LA) face a growing demand from governments and consumers: reducing energy consumption. In a region of about 20 countries, where Spanish is the dominant language and regulatory systems are based on similar legal models, this demand wouldn’t seem to be a significant regulatory problem to energy-using ...

  • Improving energy efficiency with an intelligent remote energy management system

    With the growing demand for energy efficiency solutions to contend rising energy costs, many technologies have become available in the market today. However, without intelligent and continuous energy data measurements, which can be analysed for strategic energy planning, carbon emissions, energy efficiency, reliability and electric costs, the maximising of overall savings is much more difficult ...

  • Efficiency improvement of a photovoltaic system by acting on the characteristics of MPPT control

    A 360 W photovoltaic (PV) module power with a maximum power point tracking (MPPT) algorithm is analysed and presented. In this study, the control algorithm is improved and then applied to the PV system. The results obtained show the ability of this algorithm to control high powers when weather conditions are changing. Under the same conditions, this improved technique offers, in steady state ...

  • Energy efficiency in U.S. manufacturing: the case of Midwest pulp and paper mills

    Rising international energy and labor costs are combining with historically low natural gas prices and improving productivity in the U.S. to create an intermittent resurgence of American manufacturing. In a 2012 survey of company decision makers, the Boston Consulting Group found that 37 percent of manufacturers with sales greater than $1 billion were planning to bring back production to the ...

  • Create new jobs & cut emissions by investing in renewable energy efficiency

    At a time when major US companies are announcing job layoffs almost daily, the renewable energy industry is hiring new workers every day to build wind farms, install rooftop solar arrays, and build solar thermal and geothermal power plants. The output of industrial firms that manufacture the equipment for these energy facilities is expanding by well over 30 percent a year. These investments both ...
