  • How to make top-down and bottom-up sustainability converge

    Fits and starts are all too common in the sustainability world. One year you have budget for initiatives; the next you don’t. Management hails cost savings on individual projects, but they miss the big picture and fail to link progress across departmental boundaries. Bottom-up progress and top-down directives pass each other like proverbial ships in the night. But it doesn’t have to ...

  • New ways for Metal Recycling

    REWAVE XRF 3-way-sorting in innovative  “Free-Fall”-design Recycling of metal and aluminium knows no limits because it can be remelted as scrap indefinitely. Metals, however have to be separated from non-metallic impurities, and different metals have to be sorted in pure fractions to be used as secondary raw materials substituting primary resources. Especially when it ...

  • Energy efficiency without trying (and with)

    John Lennon wrote that life is what happens to you while you’re busy making other plans.  Apparently, the same is true of energy efficiency. Energy savings happen when we’re busy doing other things – Internet-based things specifically. We use email, bank online and download music not to save energy, but to make life easier and more interesting.  Energy efficiency is a ...

  • May the Force be energy efficient

    It was hard to get excited about IBM’s Watson http://www-03.ibm.com/innovation/us/watson/ besting two humans in the TV game show Jeopardy and walking away with a $1 million prize last month. After all, thanks to the entertainment industry, we’ve seen robots and computers win in all kinds of ways, from HAL duping the smart ...

  • Hot sectors for energy efficiency

    It’s clear that the energy efficiency industry is undergoing an unprecedented boom, spurred by state and federal support and movement toward a smarter grid. But for those in the industry, where exactly can the new business – and the jobs – be found?Two new reports by Colorado-based Pike Research shed some light.After years of focusing on bringing efficiency to manufacturing, policymakers are ...

  • Efficient aeration system boosts energy savings

    A new efficient aeration system saves the Ontario, Ore., wastewater treatment facility $47,000 annually in energy costs. Besides giving this community a financial boost, the new system netted additional equipment cost savings by cutting aeration horsepower by more than half at the plant. The environmentally conscious city, located in the Oregon/Idaho border area, is meeting all of its effluent ...

  • US to lead on efficient design of energy systems

    Despite the availability of Combined Heat and Power (CHP) technologies and proven benefits and performance of these systems, projects often are not implemented even when investment is compelling. The United States will lead this effort, building on its CHP Partnership Program to identify and clear barriers to efficient design of on-site energy systems. The project will promote collaborative ...

  • The efficiency and eco-efficiency of manufacturing

    In this paper, we review the efficiency of both manufacturing processes and systems over recent decades and compare nano-materials technologies in this context. To a first approximation, nano-materials processes appear to be about as efficient as semi-conductor processes. That is, their second law efficiencies are of the order 10−5, while conventional processes are of order 10−2. ...

  • 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 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 ...

  • Energy efficiency: not a sound bite business

    I’m a star at the neighborhood playground because I write about energy. Let me explain. I have a young son, and often find myself next to the swings talking with other parents. Inevitably we talk about work. Inevitably it comes up that I know a little about energy. And inevitably I'm surrounded by a crowd that wants to know-- demands to know--why the US doesn’t use more green energy. They are ...

  • Energy efficiency: Cure for mortgage meltdown?

    By Elisa Wood October 7, 2010   My first reaction was that the Alliance to Save Energy was stretching a bit by titling its October 6 talk: “Is energy efficiency the key to recovery from the recession?” But after hearing David Goldstein’s presentation, I must admit I’m thinking about energy efficiency in a whole different way. Goldstein, author of the ...
