Energy Matters Index (ala Harper's)

  ENERGY MATTERS INDEX  ( with apologies to Harper's Index ) Current total number of U.S. jobs in the fossil fuel industries (coal, oil, gas) : 200,000 Current total number of U.S. jobs in the solar and wind power : 450,000 Potential number in the wind and solar as fossil energy is phased out : 1,000,000+ Annual sustainable energy from one acre of corn ethanol : 3.1 MWh (140 gallons)  Annual sustainable energy from one acre of trees : 6 MWh (1 cord) Annual sustainable energy from one acre of wind power : 200 MWh Annual sustainable energy from one acre of photovoltaics : 800MWh Miles that an acre of corn ethanol could move a typical small SUV in a year : 2,500 Miles that an acre of photovoltaics could move an electric car in a year : 2,000,000 Minimum acres of farmland to supply biofuel to one jumbo jet for a year : 65,000 (100 sq.mi.) Median grams of CO2 produced per kilowatt-hour of electricity at a coal fired power plant : 950 At a natural gas fired plant : 450 By a

Biomass Revisited

  Biomass Revisited Our recent column “Is Biomass a Climate Solution?” generated some feedback from members of the biomass industry in Maine. We greatly appreciate feedback, so we would like to respond. To review the column’s content, our main point was that using wood pellets from mature trees in place of oil or gas is not going to budge the global warming needle. If curbing greenhouse gas emissions drastically and expeditiously is our mission, switching to another combustion fuel is not better enough. We made a distinction between what is happening in North Carolina, the annual clear-cut of 60,000 acres to be pelletized and sent to the E.U. for biomass to meet their “renewables” quotas, and what the Maine biomass industry comprises. Perhaps we didn’t make this point clearly enough, and thereby regrettably offended some Maine biomass proponents. However, our thesis still stands: biomass burning as it is being employed by E.U. countries to meet their greenhouse gas reduction calculus i

One More Time: What Is “Carbon Pricing?”

  One More Time: What Is “Carbon Pricing?” The reason we bring this up is that national carbon pricing is important.  It is recognized by a full spectrum of economists, conservative to liberal, as key to reducing the role of fossil fuels in our economy, and by climate policy experts as critical for cutting emissions rapidly enough to avert catastrophe.  Why do economists and climate policy experts promote carbon pricing but politicians do not?  We believe the answer lies with voters - voters who do not pressure their elected officials to enact carbon pricing because they aren’t sure what it is. So here is what it is, in a nutshell.  Carbon pricing refers to placing a sort of “pollution fee” on fossil fuels to make their prices reflect their TRUE cost to society.  If the actual effects of fossil fuels -- in health damage, in environmental damage, in damage to the atmosphere -- were priced into those fuels, consumers would respond by avoiding them and favoring alternatives, including ene

Is Biomass a Climate Solution?

  Is Biomass a Climate Solution? We write this column and call it Energy Matters because it does.  Energy does matter.  In fact at this point in the history of life on Earth, it matters, arguably, more than just about anything.  It matters because the human component of the planet community has gotten us into something of a predicament by fashioning an entire civilization on a structure dependent on a constant diet of high-density energy from fossil sources of carbon based-fuel.  The predicament is that the destructive effects of this deployment of fossil fuels are heading human civilization rapidly and inexorably towards doom, dragging all other earthly communities with it.  Our energy needs constitute an addiction, withdrawal from which seems impossible. There must be a way out of this predicament, we say!  But so far no one seems to have a simple treatment.  If it is even possible, it is very, very complicated and we know we don’t have time to waste going down blind alleys.

Trees

  Trees To a non-physicist, it seems for all the world that the shade from trees could be transformational for the issue of a heating climate.  When we’re walking along a baking hot road in the summer mid-day and suddenly reach a shady stretch sheltered by a towering leafy tree, we think, “Man, it’s like night and day - trees are just the OBVIOUS ANSWER!” So when we ask the physicist, “What volume of air could we say is cooled, and cooled by how much, from the shade of one tree?” He just mutters and shakes his head.  “We couldn’t.” Non-physicist (with the righteous petulance of a 3-year old): “WHY NOT?!?!? IT’S PHYSICS!” Physicist (grimacing, head-shaking, visibly withdrawing): “No, I mean yes, it’s physics, but it’s, well, (squints, shudders) it’s biology! mixed up with geology and geography and meteorology, and well - just no.” “BUT (now ranting) IT’S OBVIOUS the air is SO much cooler when I walk through a shaded spot on a hot tar road.  If all the roads were shaded, it would HAVE to

Food or Energy: Do We Have To Choose?

  Food or Energy: Do We Have To Choose? Climate-anxious Liberal: “Whew, finally solar installations at scale are helping to turn the tide on fossil fuel generated electricity! Put it everywhere! Life’s a trade-off!” Food-security-anxious Liberal: “Horrors! The solar farms are stealing all the agricultural land, we’ll starve!” Tree-hugging Liberal: “The solar armies will spare no forests in their quest to dominate the surface of the planet!” Landscape enthusiast Liberal: “Ughh, I’m getting a headache just thinking about the future endless monotony of photovoltaics dominating my cherished views!” Can these over-wrought liberals find solace and mutual understanding on the subject of deploying renewable energy infrastructure? Unsurprisingly, we recommend they start by looking at some numbers. In a recent column we mentioned that, of the 10 acres of forest per person in Maine, if one acre were replaced with solar panels that would more than compensate for the average carbon footprint.  Here
