Clean Energy Will Depend On A New Smart Grid
Renewable energy is only as effective as the infrastructure that moves it around: the electrical grid.
Parts of the current grid are over a half century old, predating the personal computer.
From WSJ Renewables Need A Smart Grid
Even at today's levels, renewable energy is straining an electrical grid already showing signs of fragility.
The current electric grid has two basic shortcomings.
It's not big enough to accommodate all the new electricity the nation is likely to need in coming decades,regardless of how that electricity is produced. And it's not flexible enough to handle the inconsistencies of renewable energy, which is less steady than the workhorses of coal and natural gas; the wind doesn't always blow, and the sun doesn't always shine.
