  • Dumb grids

    The smart grid conversation is stupid. Policies to encourage smart grids are at best minor distractions, and at worst contrary to the public interest. Smart grids are also the key to cleaning up and modernizing the electric system. These sentences are not in conflict with one another. The smart grid is the cart, not the […]

  • The Climate Post: Uptick in denialism halts glacier melt, lowers sea levels

    First things first: “The absence of an actual bill” is one impediment to the Senate taking up climate legislation, The Hill reported earlier this week. The climate leadership troika of Sens. John Kerry (D-Mass.), Lindsey Graham (R-S.C.), and Joe Lieberman (I-Conn.) continue to work behind the scenes to steer the many interests toward a common […]

  • Know your solar

    Concerns about global warming, rising fossil fuel prices, and oil insecurity have prompted calls for a new energy economy, one that replaces fossil fuels with renewables. The sun is an enormous reservoir of energy; in fact, the sunlight reaching Earth in just one hour is enough to power the global economy for a whole year. […]

  • What’s the proper role of individuals and institutions in addressing climate change?

    This may seem like a trivial question with an obvious answer. But what really is the proper role for individuals and institutions in addressing climate change? An immediate and natural response may be that everyone should do their part. Let’s see what that really means. Decisions affecting carbon dioxide (CO2) emissions, for example, are made […]

  • The do-nothing energy tax: $3 gasoline dead ahead

    Cross-posted from the Wonk Room. The mounds of snow blackened by auto exhaust have barely melted in Washington, D.C, yet the Energy Information Administration’s Short Term Energy Outlook already predicts that average gas prices “will exceed $3 per gallon” in coming months: Average U.S. pump prices likely will exceed $3 per gallon at times during […]

  • A messy but practical strategy for phasing out the U.S. coal fleet

    By 2030, we have to stop emitting greenhouse gases from coal. That conclusion is most famously associated with NASA’s climate chief James Hansen, but Hansen is not alone. In a recent paper, nine other climate scientists — David Beerling, Robert Berner, Pushker Kharecha, Valerie Masson-Delmotte, Mark Paganini, Maureen Raymo, Dana Royer, Makiko Sato, and James […]

  • On rooftops worldwide, a solar water heating revolution

    The harnessing of solar energy is expanding on every front as concerns about climate change and energy security escalate, as government incentives for harnessing solar energy expand, and as these costs decline while those of fossil fuels rise. One solar technology that is really beginning to take off is the use of solar thermal collectors […]

  • 010 Reframing Nuclear Power as an Ally of Renewable Energy

    Photo courtesy of, ah, Bitchcakes via Flickr Alec Baldwin weighs in, but which is better, coal or nuclear? The official response to that question by most environmental organizations is to say “neither.” Neither? Are they are privy to a secret consensus finding of multiple, detailed, peer-reviewed, scientific studies which have demonstrated that when all negative […]

  • Dear Vinod Khosla & Tom Friedman: No amount of sequestration makes coal ‘clean’ [UPDATED]

    EVEN MORE UP-TO-DATE UPDATE (3/22): The New York Times profiles Calera, the Vinod Khosla-backed company that hopes to embed carbon dioxide in cement. Dave tells the full story below. UPDATE: Vinod Khosla sent in a response — see the bottom of the post. —— Tom Friedman had a column over the weekend lauding a couple […]

  • Challenging conventional wisdom on renewable energy’s limits

    In making the case for a rapid conversion away from heavily polluting energy sources like coal and nuclear power to cleaner generation, renewable energy advocates often confront the argument that their scheme is impossible due to the intermittent nature of sun and wind. But a groundbreaking study out of North Carolina challenges that conventional wisdom: […]
