Well, inspirational speeches certainly have their place.
Norway, which is the leader in the use of electric cars in Europe, wants to move to electric-only vehicles by 2025, as does the Netherlands. Both Germany and India have proposed similar measures with a target of 2030.
But I'm guessing the grand speeches didn't mention that even India plans to beat them by 10 years.
For me this is the real headline:
Other targets set in the French environmental plan include ending coal power plants by 2022, reducing nuclear power to 50% of total output by 2025
though France only gets about 4% of its power from coal. Roughly 75% of their power generation is nuclear, so that's a significant goal, but I think some would argue its environmental benefits.
A lot could happen true, but i see this more in the idea of Kennedy's "go to the moon" speech to give an ideal for people to aim at.
