Flat? or wavy?

Smart grids are supposed to flatten the demand curve by reducing peak power (i.e. with demand response) and filling valleys (i.e. with EV charging). Price arbitrage using local energy storage is another driver for a flat demand curve.

So do you think in a few years the demand will be completely flat?

I bet it shouldn’t, let me explain why…

Democratization of power generation – The ongoing innovation

There is quite some discussion on the subject of energy independence and energy democracy recently (for example, this article, or the lateral power concept from Rifkin’s TIR or the initiative from Energy Democracy TV). I’d like to post my “vote” for energy democracy and explain why it is an inevitable transition and an ongoing innovation, from dependent to empowered (literally) prosumers.

Increased energy independence of a country normally refers to a reduction of oil imports, mainly benefitial to trade balance, but it is not so straight-forward how an individual benefits of this country’s independence. If, for example, the change reduces his gas or electricity bill, he will be, but if the energy he purchases is still from the same utility at the same price, is he any more independent?

Another way of understanding energy independence concept is the “off-grid-ing”, islanding both from the network and utilities, through renewables plus storage and/or electric vehicle, for example. I’m relatively against this as it is opposed to the networked economy, where interdependence and cooperation benefits all stakeholders. It also is economically inefficient as there has to be additional generation&storage dimensioned for off-grid availability. The same self-sufficient user interconnected, even in peer-to-peer networks or communities, needs less investment, can have additional income from selling power, and has more security of supply from other generators.

This brings us back to the point of energy democracy, on who generates power and who has access to it? There lies the innovation on energy democratization. On the following video from innovation and market we can have a look at innovation process:
