Rich Karlgaard, the publisher of Forbes magazine, writes a column in every issue called “Digital Rules.” He is a very smart guy and, usually at least, very innovative and forward thinking.

I say “usually” because he just missed the boat in his latest blog entry on the future of renewables.

Mr. Karlgaard argues that we are stuck with coal, oil and nuclear as our major sources of electricity in the United States for the foreseeable future.  He asserts that “[t]here is no way the U.S. economy can enjoy future prosperity without the big three electrical energy sources of clean coal, natural gas and nuclear.”

Why?  Because only 10% of current electricity generation comes from renewable sources, and most of that comes from hydro.  Solar and wind provide less than 3% of current electricity generation.

According to Mr. Karlgaard, solar, wind and other renewables cannot possibly meet a significant part of our electricity needs 10 years from now when they are starting from such a small base.  His Forbes colleague Ken Fisher agrees, urging investors to “buy into fossil fuels” because they account for“89% of electricity” and “that fraction won’t change dramatically in the next decade.”

As for Thomas Friedman, John Doerr, and others who point to Moore’s Law and argue that renewables will experience the same rapid technological advances as semiconductors if given the right incentives, Karlgaard calls them “dreamers.”

Funny.  That’s exactly what they said about Thomas Edison, Nicolas Telsa, and others who set out to build centralized electric power plants in the late 1800’s.

At that time, centralized electric power plants had an even smaller share of the market than renewables have today.  In fact, there were only a couple of electric demonstration projects involving only a few hundred streetlights.  Gas companies had a virtual monopoly on powering lights in homes and businesses, and the new electric power plants being built had to charge far higher prices than gas.  The gas companies also had an existing and very efficient distribution system for their gas, while the electricity dreamers needed to build very expensive copper mains to carry the electricity to customers.

Edison, Telsa, Westinghouse, and the other dreamers who built our current centralized electric generation system also faced a number of very significant barriers beyond price.  There was, for example, the fact that the electric motor had not yet been invented.  So they were trying to sell electricity before it could be used in factories.

How did the dreamers prevail?  Transportation and municipal contracts.  The electricity dreamers got their break by building dedicated power plants for new electric streetcars and streetlights.

Once they built a base of electric generating capacity for streetcars and streetlights, the pace of innovation and growth quickened.  Innovators began inventing other things to use electricity, including electric motors which revolutionized the economics of running a factory.  By 1892 – less than 15 years after Edison’s first streetlight project – General Electric’s capitalization was $50 million.  The incredible speed at which centralized electric power plants developed is described in The Power Makers, by Maury Klein:

“By 1900 electricity had become an integral part of American life, especially in cities.Between 1890 and 1905 the output of electric power in the United States increased a hundredfold.By revolutionizing production and manufacturing, electricity made possible the rise of the consumer economy that was to dominate the twentieth century and transform every corner of American life.Already factories consumed more than half of the electricity generated….Arc lights illuminated the streets of even small towns and flooded with light the avenues of large cities.In 1902, some 51,000 electric streetcars whisked urban passengers along 22,000 miles of track."

Now Messrs. Karlgaard and Fisher may be correct that coal, oil and nuclear will still be significant contributors to our energy mix ten years from now.  After all, centralized electric power plants did not force the gas industry into bankruptcy.

But the history of centralized electric power plants suggests that renewables can and will grow at a much faster pace than traditional fossil fuels as sources of electricity.  Once started, that pace will accelerate as the competitive advantage of renewables starts having a significant impact on the bottom line.

Think about it.  Five years from now, those who invested in solar and wind today will have ZERO fuel costs for that portion of their electricity needs, while those who did not invest in renewables today will still have to pay the cost of fuel for every kWh – and at higher prices than it is paying today.  Add in the fact that renewable technologies five years from now will be even more efficient than today, and everyone will be clamoring for renewables.  It is easy to see how the tipping point will be reached.

Or has it already been reached?  China has just announced that it is constructing a 2 gigawatt solar power plant in Inner Mongolia, the largest solar plant in the world. That is on top of nearly 80 gigawatts of renewable energy that China has already built in recent years. When China has hundreds of gigawatts of fuel-free energy, what country will be able to compete when it must continually pay for fossil fuels to generate 90% of its electricity? More to the point, what country can afford to wait?
