"As more of these elements break away from the "connected" grid, the real challenge becomes management and control. Customers aren't interested in running their own power plant. They just want the lights to go on when they hit the switch. And in this sense, the approach of the service providers in the 90's is very instructive."

Welcome to the renewable energy sector, Mark. Your analysis is worthy of study and thought and is like a bright light leading the way to business success for renewables much as there has been for the internet. I think it is only a matter of time and technological development before renewables hit their stride in the business world. It is people with your type of clear thinking that will help to make it happen.

By the way, there was a Culpepper who wrote a very good book on herbs a century or two ago.

hmmmm, just thinking, didn't GE buy up Solar Somebody out of bankruptcy last year? Is that the sort of big fish eating little fish thing that Mr Culpepper is referring to? Maybe only big fish have both the money and the management skills to make this technololgy take off.

Distributed Generation is where the "PC" was in 1981, just before Microsoft incorporated. Before the eighties no one had a PC, after the '80s everyone had one. The 21st century grid follow suit.

I would suggest that new Vertical Axis Wind Turbine technology offers the lowest capital cost of all DG technologies. Solar panels, without optical concentration, seem less likely to be the technology that makes true DG practical. (Current flat-plate PV panels average over $4 per watt). This does not include Balance of Systems costs, just the primary power converter.

DG wind power systems that are not "propeller" based offer technology that can actually be used in urban environments. Safe for wildlife, silent running, able to work across a wide range of wind speeds. At $1.50 per watt DG wind seems poised to be the driving wedge.

Mark has the correct perspective. The PC enabled local computing power and made timeshare of lcentral computers history. One can see the same paradyme shift from central to local power sources in the 19th century factories. The water wheel, steam engine or a single large electric motor centrally created motion which was distributed via shafts and leather belts to the individual machine tools. The fractional horsepower electric motor changed all that. Today we generate motion locally using cordless drills etc. The future will see electricity generated at the point of load. Transmission lines were only necessary for the first 100 years. Like the small motors and the cheap hard drives in the datacom example, the enabling technology in distributed generation will be low cost PV modules and highly reliable electronic equipment to store and convert the DC to standard AC power.

A very good article Mark. I enjoyed it very much and it is "right on".

The real problem today in getting started is that there is no real economic or regulatory incentive for the utilities to act. It is crucial that we get serious about a national renewable energy portfolio at the federal level which the politicians don't seem to be able to grasp or which the utility lobby is squelching.

Also, don't get caught up on turbines and fuel cells. Their day will come but the "old" reciprocating generator is still king functionally and economically at this point. Can black start, do standby as well as prime, doesn't derate significantly with temp and altitude and can use a wide variety of alternate and renewable fuels.

Mark,
You are right we are shifting from highly centralized systems, to highly distributed systems.
