The founder of the global climate-action group 350.org, Bill McKibben, just sent out a tweet that should catch the attention of world leaders.
At the time of McKibben's tweet, 115 percent of Denmark's electricity was being generated by wind and solar.
The surplus was being exported to Sweden and Norway.
Later this year, heads of state will attend a United Nations COP21 climate conference in Paris to try to stem greenhouse-gas emissions and stave off a planetary crisis.
Denmark is acknowledged as the world leader in renewable energy. Its goal is to end fossil-fuel use by 2050. When the winds are blowing hard and the sun is shining, Denmrak's capacity for generating wind and solar power increases.
Here in Vancouver, Mayor Gregor Robertson recently introduced a motion at council to ask staff to examine steps the city can take to generate all of its energy, including transportation fuels, through renewable sources.
This was also the topic of a conference in Vancouver last week put on by the SFU Centre for Dialogue's Renewable Cities initiative.
B.C. Hydro generates more than 95 percent of its power through renewable sources, thanks to its heavy reliance on hydroelectric facilities. However, Canada's overall record in addressing the climate crisis has attracted international contempt.
In a 2013 ranking of 61 countries, Canada ranked 58th in making progress in reducing greenhouse-gas emissions. The only countries that fared worse on the list were Saudi Arabia, Kazakhstan, and Iran.
