The CBC brings to attention a draft report from a federal government think-tank which warns that Canada's status as an "energy superpower" is under threat from the current trend of moving towards renewables energy. The report predicts "significant disruptions" in 10 to 15 years as "cheap renewable electricity becomes the world's primary power source."

Due to the intermittent output from solar panels and wind turbines, making a major shift to renewables would require "vast, vast storage technology," Moore said, which adds to the cost and viability of such a change.
Reed, however, said there are various ways to tackle the problem, and solutions go beyond merely building better batteries.
"You certainly need an energy-dense battery if you want to have a car, but for electrification of the grid, you actually don't need energy-dense batteries," he said. "What you need are low-cost energy storage systems that meet the needs of whatever system you're trying to build."
