Is Storage Necessary For Renewable Energy?
mdsolar writes Physicist and energy expert Amory Lovins, chief scientist at The Rocky Mountain Institute, recently released a video in which he claims that renewable energy can meet all of our energy needs without the need for a fossil fuel or nuclear baseload generation. There's nothing unusual about that — many people have made that claim — but he also suggests that this can be done without a lot of grid-level storage. Instead, Lovins describes a "choreography" between supply and demand, using predictive computer models models to anticipate production and consumption, and intelligent routing to deliver power where it's needed. This "energy dance," combined with advances in energy efficiency, will allow us to meet all of our energy needs without sacrificing reliability.
He's a physicist. He was just imagining the electrical grid as a perfect sphere on an infinite frictionless plane.
Never worked as an academic physicist, never even completed a degree apparently.
Never worked in the power industry.
Never manufactured EE Equipment.
Nevertheless knows how to power the world?

bah. Engineering is about being able to tell somebody that, say, a bridge can be built in X days, bearing Y load of such and such type, endure for Z years at a cost $$$ AND be able to explain that we actually don't have analytical equations for all the physics that relate to it. Engineering is about taking responsibility in delivering the collected knowledge about technical systems of the past, for addressing current and future needs. As an engineer, it is nowhere written that you grasp the whole physics about a technical system, although you are still held accountable for its performance - as a minimum, to explain observed behavior.
