One of the most important energy matters to accurately understand, is the reality that popular “renewable” electrical energy sources are not even remotely equivalent to our conventional energy sources.
Of course lobbyists don’t want consumers and politicians to think about that fact, so they go to great lengths to disguise it. Everything they propagate is based on an “equivalency” between “renewables” and conventional power sources that does not exist in the real world.
Even generally objective sources like EIA seriously err when they show such things as levelized cost charts that have wind energy and nuclear power in contiguous columns.
The first problem encountered here is the term “renewables.” This is bantered about like it is: 1) a scientific definition, and 2) a homogeneous group of energy sources. This is lobbyist sleight of hand, as neither is true. It isn’t my purpose here to go into the details of this charade but suffice it to say that the definition is very subjective, AND there are
extraordinary differences between various “renewables.” (See <<http://tinyurl.com/2ex8xf9>> and <<http://tinyurl.com/2fcpmpb>>.)
After you’ve grasped those details, the heavy lifting begins. The trick here is to get our heads around the fundamental difference between something like wind energy and nuclear power.
I’m just a physicist and not a professional communicator, so wordology doesn’t come natural to me. However, what I have learned is that most people have a better chance of understanding complex matters when an analogy is used. Let’s try that here.
My suggested comparison is to look at two types of transportation (a parallel energy sector), using concepts we are all familiar with.
Let’s say that we have a business that repeatedly needs to get 50,000 pounds of goods from New York City to Denver, in two days, and cost is quite important. [In the electricity business this translates to satisfying a demand (load), through dispatchable energy, reliably and economically.]
So who do we subcontract this job to? A good option is to put this merchandise on an 18-wheeler and send it on its way. Will it always get there 100% of the time without fail? No, flukes do happen. However, if this experiment was repeated 100 times, the truck would arrive well over 90% of the time, on schedule and within budget. This is equivalent to using a conventional energy source, like nuclear power.
Now let’s say greenologists are introduced into the equation, and they arbitrarily add a new requirement that no fossil fuel can be used. Oops. Our options are now severely restricted.
The parallel choice to using wind energy is to send the merchandise with golf carts (battery powered so no fossil fuel will be consumed during transport). The question is: how many golf carts will it take to dependably replicate the performance of one Mack truck?
Let’s say a golf cart can carry 500 pounds (two golfers with sticks). To transport 50,000 pounds that would work out to 100 golf carts.
This is essentially the message that the lobbyists want you to buy: that approximately 100 golf carts (wind turbines) will do the job of one 18-wheeler (conventional source: e.g. a coal facility). They want you to blink and move on. Do NOT look behind the curtain!
But wait! Can the golf carts get really there in two days? Of course not. The lobbyists answer is to add more vehicles: use 1000 carts!
Does this “solution” really solve anything? No, but it further confuses politicians not used to critical thinking. What it also does is to insure more profit for the cart industry — which is the ONLY concern of the the lobbyists.
What if the load is a hundred 500 pound pianos? Even though (on paper) a golf cart can carry 500 pounds, can a golf cart transport a piano across country? The lobbyists’ answer: disassemble it.
And will the cost of the golf cart option be comparable to the truck choice? Just to begin with there are 100+ drivers vs one — so I think you know the answer, right?
And what else will be needed to support this ”alternative” source of transportation? A lot: like battery recharge stations throughout the country. And who will pay for that? Duh.
And what is the source of the electricity used to charge the cart batteries? Mostly fossil fuels. Oops.
In the face of this evidence, the lobbyists and their academic coconspirators distractingly wave their hands and say such non-sequitors as “Don’t worry about these details.
Everything will make more sense mañana. Increase our subsidy and we’ll do a better job.”
This isn’t how science works. BEFORE we pay them to run this route, these promoters should tell us exactly how many golf carts it will take, and then PROVE IT by actually running this route dozens of times. We would then have real-world evidence of the reliability and cost of their proposal. This is exactly what we have NOT done with wind energy.
They have not only skipped right over the proof stage, right now the golf cart lobbyists are working on convincing our politicians that since businesses been “resistive” to using their transportation product, that they need a law MANDATING that 20% of all goods from NYC to Denver go the golf cart route!
And the claimed benefit of all of this? Economic recovery. There will be lots of new jobs in the golf cart business! What about the economic loss due to the higher shipping cost, or the slower transportation? Don’t worry about it. Come back mañana.
Hopefully this analogy makes things clearer, as this is the insane path we are now on.
May 10th, 2010 at 10:18 AM I was of the opinion that the use of wind energy was only a component of the overall plan to reduce our dependency on foreign oil. It was never to replace it. If we can find ready uses for wind energy that is cost effective, like the wind farm being built off the coast of Cape Cod, that will provide enough energy for all the homes and businesses on the islands of Nantucket and Martha's Vineyard, then that reduces the need to have that energy provided by fossil fuels. I don't think anyone truly believes we will ever be free from buying foreign oil.
May 11th, 2010 at 10:53 AM Douglas: That is yet another lobbyist generated rumor. Sort of like saying let's send part of the merchandise from NYC to Denver by golf carts. Would ANY part make sense? 1 - Only about 1.5% of our electricity generation comes from oil: a trivial amount. 2 - The Cape Wind project will power zero homes 24/7. 3 - Good that you note that it should be "cost effective." Already the Cape Wind project has signed contracts that will increase electricity costs some 300%. Is that cost effective? 4 - Denmark's electricity costs are 350% of what ours are, so this is no surprise. 5 - See "http://EnergyPresentation.Info" for more details.
