  • Canada pulls out of climate treaty
    Tuesday, December 13, 2011

    TORONTO - Canada's environment minister said Monday his country is pulling out of the Kyoto Protocol on climate change.

    Peter Kent said that Canada is invoking its legal right to withdraw and said Kyoto doesn't represent the way forward for Canada or the world.

    Canada, joined by Japan and Russia, said last year it will not accept new Kyoto commitments, but renouncing the accord is another setback to the treaty concluded with much fanfare in 1997. No nation has formally...

  • Cost-cutting technologies can help U.S. compete in solar
    Tuesday, December 13, 2011

    It wasn't exactly a chamber-of-commerce day in Tucson as a key U.S. Energy Department official visited on Monday to talk solar energy with local researchers and industry folks.

    But despite the rain and gloom outside, Ramamoorthy Ramesh delivered a message of hope and urgency in a meeting at the University of Arizona Science and Technology Park.

    Ramesh is director of the DOE's Sunshot Initiative program, which aims to cut the unsubsidized, installed cost of solar energy...

  • TEP seeks final OK of renewable- energy plan
    Monday, December 12, 2011

    State regulators this week will decide on a proposed renewable-energy plan filed by Tucson Electric Power Co. for next year that would sharply cut back on ratepayer subsidies for commercial renewable-energy installations - a move solar installers say could cripple the industry.

    The Arizona Corporation Commission will meet Wednesday to consider TEP's plan, which also would lower per-watt cash incentives for installing renewables and offer lower rebates for leased systems.


  • Climate action alive, but core issue dodged
    Monday, December 12, 2011

    JOHANNESBURG, South Africa - The hard-fought deal at a global climate conference in South Africa keeps talks alive but doesn't address the core problem: The world's biggest carbon polluters aren't willing to cut emissions of greenhouse gases enough to stave off dangerous levels of global warming.

    With many scientists saying time is running out, a bigger part of the solution may have to come from the rise of climate-friendly technologies being developed outside the U.N....

  • City seeks largely voluntary steps to cut energy use
    Monday, December 12, 2011

    City officials are pushing a largely voluntary strategy to cut greenhouse gas emissions as a way of fighting climate change.

    On Tuesday, the Tucson City Council will discuss a climate plan asking homeowners, businesses and industries to reduce energy use over the next eight years. Authorities hope that these strategies will get the city halfway toward a goal of producing 7 percent fewer greenhouse gas emissions by 2020 than were produced in 1990.

    One - a tightening of energy-...

    DURBAN, South Africa - A U.N. climate conference reached a hard-fought agreement early today on a complex and far-reaching program meant to set a new course for the global fight against climate change for the coming decades.

    The 194-party conference agreed to start negotiations on a new accord that would put all countries under the same legal regime enforcing commitments to control greenhouse gases. It would take effect by 2020 at the latest.
