    From Good Intentions to Deep Decarbonization

    The most important issue is whether countries will achieve their 2030 targets in a way that helps them to get to zero emissions by 2070. If they merely pursue measures aimed at reducing emissions in the short term, they risk locking their economies into high levels of emissions after 2030. The critical issue, in short,…

    U.S. Could Cut Per Capita Greenhouse Emissions 90% by 2050, Says Report

    The report says it is possible to revamp the energy system in a way that reduces per capita carbon dioxide emissions from 17 tons per person currently to 1.7 tons in 2050, while still providing all the services people expect, from driving to air conditioning.

    Before Paris, Cause for Optimism

    If the international community were to fully understand the threat of climate change, and the likely cost of mitigation and adaptation, perhaps we would commit to continued tax breaks and incentives, and propel the renewable energy transition toward completion. In the long run, I am sure this would be less expensive than coping with the…

    The Race for Better Batteries

    The worldwide transition from fossil fuels to renewable sources of energy is under way, but to integrate all this variable power into the grid, battery storage is key. Researchers around the world are working on developing better and cheaper batteries.

    In a Melting Iceland, Drilling Deep to Stem Climate Change

    Iceland is pioneering a new technology to deal with climate change. Its Hellisheidi geothermal power plant, the world’s largest, hosts arguably the world’s most advanced program to capture and lock away globe-warming carbon dioxide.

    Photo Essay: Iceland at the Cutting Edge of Climate Change

    Iceland has a complicated relationship with climate change. As in much of the far north, global warming is already exerting many effects here–arguably both good and bad. Yet the country contributes relatively little to the warming, since most of its energy comes from geothermal and hydro plants, which produce little carbon dioxide. Now, it is…

    Charting the Course to a Renewable Energy Future

    As environmentalists have pushed for greater investment in wind and solar energy, critics have insisted that renewable sources of power could never provide more than a fraction of world energy demand. Evidence is mounting, however, that the critics are wrong.

    A new interactive, color-coded map created by a team at Columbia’s engineering school allows viewers to pinpoint and compare estimated energy usage, building lot by building lot, throughout New York City.

  • Implementing the Lean Smart Grid

    As utilities and suppliers begin the modernization of the electric grid in the United States into the “Smart Grid”, there seem to be two schools of thought circulating across the country. There are those looking forward to the change and those dreading the consequences of the change. Those looking forward to the change are anticipating…
