  • The Electric Cities of the Future

    We all hate getting caught in urban traffic jams; especially those with semi-trailer trucks everywhere. A Computer Aided Lean Management (CALM) approach to traffic congestion in the cities of the world creates win-win solutions to such complex problems. My favorite is to lower the volume of vehicles on the roads by voluntarily moving people to…

    ImagineH2O’s 2010 Water Energy Nexus Prize Announced

    ImagineH2O’s 2010 Water Energy Nexus Prize is a global competition for water businesses that save energy. Possible areas of innovation include energy efficient transport, treatment and use of water.

  • The Policy Buffet (Part 5): How the Oil Spill Killed the Climate Bill — and Why the Economy Didn’t Help, Either

    The Policy Buffet (Part 5): How the Oil Spill Killed the Climate Bill — and Why the Economy Didn’t Help, Either

    The climate bill has come and gone. Just two months ago, it seemed as though the bill stood a fighting chance, given the buffet of options available to policymakers.

  • The Policy Buffet (Part 4): Eulogizing the Climate Bill that Wasn’t

    The Policy Buffet (Part 4): Eulogizing the Climate Bill that Wasn’t

    On July 22, just days before the National Oceanic and Atmospheric Administration (NOAA) declared that the last decade was the warmest on record, the United States Senate abandoned its effort to put a price on carbon. Comprehensive climate and energy legislation was on life-support for weeks until Senate Majority Leader Harry Reid (D-Nev) announced that…

    Struggle to Keep Fish, People & Power Companies Happy

    There’s that water-energy nexus again – power plants in NYS are under scrutiny for damaging aquatic habitat and the DEC is working on a policy to limit their impact. Over 17 billion eggs, larvae and fish are killed each year, but opponents to the policy say it could cause NYS energy costs to sky-rocket.

    People Turn Off Lights in Vain, Ignoring Real Efficiencies

  • Climate and the Border: Why Rising Temperatures Will Add Immigration Challenges

    Climate and the Border: Why Rising Temperatures Will Add Immigration Challenges

    When experts warn of the consequences of global climate change, they usually cite impacts on natural systems. They tell us that ice caps will melt, sea levels will rise, extreme weather will become more common, droughts will increase in frequency, oceans will become more acidic and so on. In recent years, we have also come…

  • Distributed Generation and Renewables in New York City

    As climate change threatens an increasing frequency of heat waves like the ones New York City has been experiencing, we city-dwellers turn to our air conditioners and window fans to keep cool.  It’s an act of adaptation: we adapt to the heat by cooling off our homes – but it counters mitigation, as increased electricity…

  • Beyond Carbon: How Fixing the Ozone Layer Contributes to Climate Change

    Beyond Carbon: How Fixing the Ozone Layer Contributes to Climate Change

    The greenhouse effect is not all about carbon dioxide. Several other substances, such as water vapor and methane, also play a key part in trapping radiation. Recently, a family of relatively obscure chemicals called hydrofluorocarbons, or HFCs, has entered the spotlight due to its role in global warming. HFCs are highly potent greenhouse warmers –…
