Barack Obama, Justin Trudeau and Enrique Peña Nieto, have made a joint announcement. As reported by NPR:

President Obama and his counterparts from Canada and Mexico are preparing to unveil an ambitious new goal for generating carbon-free power when they meet this week in Ottawa.

The three leaders are expected to set a target for North America to get 50 percent of its electricity from nonpolluting sources by 2025. That’s up from about 37 percent last year.

Aides acknowledge that’s a “stretch goal,” requiring commitments over and above what the three countries agreed to as part of the Paris climate agreement.

The news reports and press information about this event note that the US currently produces about a third of its energy from non fossil fuel sources. Mexico produces less than 20% of its power this way, and Canada is at about 81%. A big part of this shift will involve shutting down coal plants and expanding wind and solar. However, this mix, as well as the proposed 50% of “clean energy,” may include biofuels, which are very limited in their effectiveness in combating climate change, Nuclear, which is diminishing in its importance, and possibly “carbon capture” which is not an energy source and not likely to have much impact because it essentially doesn’t work at any meaningful scale because of physics.

So, we will need to see some clarification in this area.
