I believe in Renewable Energy, and here’s why

By Dr. Matthew Watson

Renewable energy (RE) is a subjective and divisive topic, one that is influenced by many factors, including corruption, greed and purposeful ignorance, scientific and technological advances, and simple entrepreneurial spirit vs. entrenched interests.

Here are some of the reasons that I believe that we will see RE replace old energy by the midpoint of this century:

* It has been estimated that an area 55 miles by 55 miles dedicated to current solar technologies could replace all the electrical generating power of coal and oil (in the US). Or an area 80x80 miles to replace oil, coal and natural gas. (Here in the US we have over 100,000 square miles of desert, so space isn’t a problem)

* Regarding storage technologies (1) for when the sun is down: consider the advances taking place in fuel cells, batteries (LI, redox flow batteries, and 1300-ton battery modules used for grid stabilization), flywheels, compressed air, ultracapacitors and the likelihood that we will also use battery powered vehicles as storage.

* Regarding “getting the power from the solar installation to the people” – consider advances in superconducting wire and other advanced materials which are very likely to enable cheap and efficient transmission of power from where ever it is generated to where ever it is needed.

* Rooftop and local solar: My solar powered home won’t have to worry about darkness; we’ll tap into the battery reserve, as will all rooftop solar installations. A small percentage of our overall use to be sure, but significant none the less.

And as for explicit subsidies: on a per-energy-unit basis, then yes, solar has received more subsidies than fossil fuels in the very recent past. However, on the amount that each of us taxpayers has spent in a recent five-year period, fossil fuels subsidies far exceed solar.

Estimates range: (2)

Coal subsidies = somewhere between $17B and $72B
Solar subsidies = somewhere between $500M and $5B

And let us not forget that coal subsidizes also include intangible (and often purposefully left out) costs for cleaning up the ecosystem, and the public health expenses associated with all of the damage that the mining and use of coal causes. (3)

In my opinion, at the end of the day it all boils down to two simple facts: 1) technological change is on a double exponential growth curve (4) and 2) simple entrepreneurial spirit.

While we certainly need to wean society off finite, dangerous, polluting resources like coal and oil, the earth can and may go to hell in a handbasket. However, I think that entrepreneurial spirit and the certain fact that there is a barrel of money to be made in renewable energy solutions suggests that we will see RE replace old energy by the midpoint of this century.

A123 Systems currently sells 2MW to 200MW grid stabilization systems (battery systems). Being used for large-scale energy storage deployment to support wind and solar integration. Small in comparison to the overall needs, but just one of many rapidly improving technologies.

“If investments in the smart grid infrastructure continue, electric vehicles may become ubiquitous — both because of the economic and environmental sense they make for consumers, and because of the vast store of batteries that will be available to grid operators to balance out the intermittency of wind and solar resources.”

“There are several major studies and research showing how the United States could reach 100 percent renewable electricity by 2050. Over the next two decades, the continually rising costs of fossil fuels will make it prohibitive to continue burning them, so we’ll witness the overdue transition to a largely renewable system. Smart grid upgrades will feature two-way communication to consumer appliances, real-time pricing information, more efficient transmission infrastructure, and advanced battery and flywheel technologies to balance the inherent fluctuations of wind and solar resources.”


(2) “What if solar got the same subsidies as coal?” (Oct 21, 2010)

Coal subsidies: The U.S. coal industry enjoyed subsidies of around $17 billion between 2002 and 2008, including tax credits for production of "nonconventional" fuels ($14.1 billion), tax breaks on coal royalties ($986 million), exploration, and development breaks ($342 million), according to a study by the Environmental Law Institute.


Solar and wind subsidies: So far, the government has handed out about $5.4 billion, according to the Energy Department.

(4) “Most long range forecasts of technical feasibility in future time periods dramatically underestimate the power of future technology because they are based on what I call the “intuitive linear” view of technological progress rather than the “historical exponential view.” To express this another way, it is not the case that we will experience a hundred years of progress in the twenty-first century; rather we will witness on the order of twenty thousand years of progress (at today’s rate of progress, that is).” Ray Kurzweil http://www.kurzweilai.net/the-law-of-accelerating-returns

(5) During the past 11 years, as the editor of the leading nanoscale technologies web portal, I read and posted over 50,000 articles about advanced and frequently mind-blowing technologies. I have closely followed the very rapid progress in our understanding and utilization of the unique properties of the nanoscale (which greatly differ from the properties that we already understand). At the very least, we are headed for a future that not one of us can predict; what we can predict is that we will undoubtedly see old myths about technologies shattered and changes beyond our current level of comprehension.

Carla wants to know

By Dr. Matthew Watson

In response to a question posed by one of my oldest and most perceptive friends, I posted what follows to my Facebook profile.

Her question was posed after watching this video http://vimeo.com/15979195

"Rocky, am I really ignorant and paranoid?

It seems like this technology holds they key to either really, really good stuff for us as a species, or it has the potential for really really bad stuff.

I trust the science and the scientists. I don't trust the Money that controls what's done with the science.

Einstein was a really nice guy. He had no idea his science would be used for war. I don't think any of the Manhattan Project scientists went into it knowing what they were unleashing on the world."

~ Carla Conrad

My answer: A most perspicacious observation, and right on the mark. Occam’s Razor, 21st century style, meaning that you have hit upon the simplest explanation for the potential outcome; like every technological innovation in the past, nanoscale technologies have both the potential for tremendous good and/or tremendous bad. And don’t let my seemingly cavalier use of "tremendous" lull you into a false sense of security; I mean "tremendous" as in "things that have the potential to change everything we think we know about ourselves, while enabling each of us with the power to effect and experience our surroundings in ways heretofore only imagined."

I have been actively and intensely following nanoscale technologies since the early ‘90’s. At the end of the day, my most prescient observation would be that these technologies will have an impact on our global society many times greater than ALL past technological revolutions. Let me put it another way: nanoscale technologies - and the products thereof - will enable far greater change than our discovery, development and use of fire, bronze, iron, steel, electrical power, cars, planes and space travel put together.

Any person, institution or government entity that says "Oh yeah, nanotechnology, we got that handled" is lying their ass off. Equally, any person, institution or government entity that says "Oh yeah, nanotechnology, it’s gonna kill us all in one or more horrible ways" is also lying their ass off. Anyone that fervent usually has a hidden agenda, and one which serves a higher master. You’ll notice I said "usually" – many of my colleagues in the nanospace are humanitarians in the best sense and are talking about and planning for ways in which the good things can be emphasized and the bad minimized or eliminated.

My philosophy is summed up thus:

Nanotechnology will certainly play a pivotal role in our future; now, with the introduction of lighter/stronger materials in the auto, space, and military industries, and later, with the introduction of molecular manufacturing (making items per your specifications, in your own home, for pennies on the dollar of current prices – think "replicator" and you will not be too far off).

Expect to see revolutionary changes in solar, fuel cell and hydrogen storage technologies within the next few years. And expect to see a great deal of interest in and subsequent higher funding of nanotech-enabled sensor technologies for military, homeland security and civilian applications within the next few years. Put another (albeit obvious) way: expect to see cultural tsunamis of a magnitude that rival anything we have thus far experienced.

No informed person doubts that developments at the nanoscale will be significant. We debate the time frame, the magnitude and the possibilities, but not the likelihood for large-scale change. The least-speculative views suggest that we're in for changes of an order that justifies – if not demands – our undivided attention. Will we be ready? (BTW: not kidding, not even the weensiest amount)

OK, off my high horse and back to your previously programmed station…
