I meant easier in terms of infrastructure already existing. Things like vehicle-to-grid, and Tesla Powerwalls are already on the market, so with the right incentives the power storage in the grid can scale with the speed renewables are scaling up.

It won't be exactly inline, which is why windfarms are built with the ability to switch off if the grid rejects the power they're creating, but it's a start.

I agree with you about the failures in power delivery infrastructure. The UK is very slow to connect up new wind and solar farms because the grid cannot scale up fast enough. New wind farms sit idle for months before they're connected to the grid, which is pretty crappy. Needs more focus and investment, maybe even marketplace competition to get things going, if we're looking for capitalist solutions to things.
