    Solar: A brilliant way to get energy

    February 3, 2016

    Paris changed everything, so why are we still talking pipelines?

    January 28, 2016

    I don't get the current brouhaha over Kinder Morgan, Keystone XL, Northern Gateway or the Energy East pipelines. Why are politicians contemplating spending billions on pipelines when the Paris commitment means 75 to 80 per cent of known fossil fuel deposits must be left in the ground? More »

    Paris Agreement marks a global shift for climate

    December 17, 2015

    The 21st Conference of the Parties (COP21) may have been our last chance for a meaningful agreement to shift from fossil fuels to renewable energy before ongoing damage to the world's climate becomes irreversible and devastating.

    The interplay of environmental degradation and geopolitics has had alarming repercussions. Over the past decade alone, millions of people have been displaced by war, famine and drought.

    Oceans supply half our oxygen, absorb a quarter of our emissions, produce food, regulate climate and weather, give us medicine, culture, renewable energy and jobs, and support a diversity of life. We can't live without them. More »

    If we're going to build, let's build green. Green infrastructure complements and reduces costs associated with traditional grey concrete, steel and asphalt infrastructure.
