Getting that energy when you need it, where you need it, is another story......
IMHO, we need a combination of significant changes on the demand side (time of use, intensity of use, overall reduction in consumption) AND adaptations on the supply side (smart buildout of renewables, better use of existing infrastructure, targeted deployment of storage).
We also need to recognize that the last 10-20% of fruit on the electricity-emissions tree are really hard to reach -- whereas there are huge gains to be made in transportation and agriculture (reducing air-travel, imposing standards on trucks/ships, and severely limiting animal agriculture)
