In a forceful speech tonight, President Barack Obama asked America to join him in bringing about a revolution in how we produce and use energy.  Already in his young presidency, he has signaled his desire to regulate greenhouse gases from cars and trucks, increase their fuel efficiency, and put in place high speed rail and other farsighted transportation policies.  Last week, he signed into law a stimulus package with $80 billion dollars - nearly a tenth of the overall package - in renewable energy, energy efficiency and cleaner forms of transportation. Tonight, he called on Congress to enact a market based cap on global warming pollution to help make clean energy the most profitable and help our nation tackle two huge issues - our dependence on oil and global climate change.

One of the President's first lines tonight was "we import more oil today than ever before". He went on to say that this dependence is "our responsibility" and that this is a time for bold action. He continued that "it is time for America to lead again" dedicating his administration to change the way we produce energy as one of his three top priorities. He committed to doubling the nation's supply of renewable energy in three years and making our homes and buildings more energy efficient. Framing this was his statement that "we know the country that harnesses the power of clean, renewable energy will lead the 21st century".

Last week, the President made his first foreign trip of his presidency to Canada. His words there were gentle but he gave the same message.  As he said tonight, "to truly transform our economy, protect our security, and save our planet from the ravages of climate change, we need to ultimately make clean, renewable energy the profitable kind of energy. "  It's hard to miss the underlying message that the days of producing energy and oil at any cost are over.  Dirty fuels - like coal in the U.S. and Canada and oil from the Canadian tar sands - now stand in stark contrast to his commitment to build our infrastructure around renewable energy rather than new pipelines and expanded refineries to process more dirty tar sands oil.

The President also made it clear last week in Canada that these measures that will make us more energy secure.  Payments for foreign oil drain nearly a trillion dollars every year from our economy in the form of debt. Our addiction to oil has put Americans and innocent civilians in harms way in the Middle East, lined the pockets of dictators, and despoiled some of our last wilderness areas in North America and around the world. And most fundamentally, our energy use is driving our planet inexorably towards catastrophic global warming. In recognition of this challenge, he said in Ottawa:

"We are very grateful for the relationship that we have with Canada, and Canada being our largest energy supplier, but I think that increasingly we have to take into account that the issue of climate change and greenhouse gases is something that's going to have an impact on all of us and as two relatively wealthy countries, it's important for us to show leadership"

How will Canada respond?

This week, Ontario will introduce a path breaking clean energy act. British Columbia has long led in producing advanced batteries and fuel cells. Alberta and the plains provinces have some of the world's best wind power. Ontario, British Columbia, and Manitoba are expected to introduce low carbon fuel standards modeled on California's vanguard effort to reduce carbon in our fuels. And many provinces are now moving to protect the Boreal forest, our largest land-based terrestrial storehouse of carbon.  There is much opportunity to work together.

But like the U.S. dependency on coal (and on tar sands oil as Canada's largest customer), we have the challenge of making sure that these opportunities become the mainstream and that the old and perilous sources of energy rapidly become relegated to the past.

The production of tar sands oil is a challenge for both the U.S. and for Canada. But what is heartening is that our President is saying we need to move on.  By putting in place a cap on pollution and transportation policies like more stringent fuel economy and low carbon fuel standards, we can reduce our dependence on tar sands oil. What remains to be seen is whether Canada will join in this effort and start to shift its economic engine from the tar sands to greener forms of energy production and let the Boreal forest do what it does so well on its own - regulate our climate.   

As the President said, "It is time for America to lead again." Indeed. It is time for all of North America to lead again.
