  • Sustainable improvement of drinking water quality by nanofiltration powered by renewable energy

    Desalination membrane technology is increasingly used for water production. However, the main disadvantage of desalination is related to energy consumption and CO2 emissions, so desalination powered by renewable energy (RE) is getting interest. In this study nanofiltration (NF) membranes have been used for drinking water quality improvement in a pilot plant (50 m3/day) powered by RE ...

  • Calcium Carbonate, a solution to the energy crisis!

    A 'chemical' solution exists to solve jointly the energy crisis and CO2 release. Thanks to the Lime, “Cycle C4” could produce liquid fuels (petrol, diesel, etc.) with no CO2 release. The cycle presents no technological uncertainty, each step is widely known and controlled. Profitable with a barrel quote at 100 dollars. In 2004, the International Energy Agency annual report predicted that oil ...


  • On energy, we`re finally walking the walk

    The United States has entered a new energy era, ending a century of rising carbon emissions. As the U.S. delegation prepares for the international climate negotiations in Copenhagen in December, it does so from a surprisingly strong position, one based on a dramatic 9 percent drop in U.S. carbon emissions over the past two years and the promise of further huge reductions. Prominent among these ...

  • Battery Storage will have a Profound Impact on Smart Buildings

    Often the best ideas are the most simple and elegant. If electric vehicles and consumer devices can have battery storage why can’t buildings? And if buildings can pull electricity from the grid at off peak times and store it in batteries, wouldn’t that save money? Since 2009, Stem based in California, have been working on these questions and disrupting the energy storage industry. ...

  • Who gets the EE stimulus money?

    The ink is dry on President Obama’s signature to the federal stimulus bill and word is out that energy efficiency receives more than US$20 billion. How will homeowners and businesses benefit? Two sources offer an excellent break-down on the incentives: the Alliance to Save Energy and the Office of Energy Efficiency and Renewable Energy, a unit of the US Department of Energy. EERE goes so far as ...

The proposed cap-and-trade policy will require all ...


  • U.S. headed for massive decline in carbon emissions*

    For years now, many members of Congress have insisted that cutting carbon emissions was difficult, if not impossible. It is not. During the two years since 2007, carbon emissions have dropped 9 percent. While part of this drop is from the recession, part of it is also from efficiency gains and from replacing coal with natural gas, wind, solar, and geothermal energy. The United States has ended a ...

  • Efficiency beyond pizza money: The military’s gigantic bite

    Is efficiency worth the bother if you save only $5-$10 per month on your energy bill? Many homeowners think not. One dad told us his family would rather save money by just skipping a pizza order once a month. That sentiment is not unusual.   But it is hard to negate the economic value of efficiency if you spend $20 billion per year on energy, as does ...

  • Don’t let a financeable asset go to waste

    Try going to the conventional financial markets and see what’s available in the project finance arena. Not much, is there? Even if you are lucky enough to have access to something, is it attractive? Chances are, unless you are well capitalized already (and therefore may not need financing), the debt markets will require a substantial equity position if not a majority position by the ...
