My review of the NREL Western Wind and Solar Integration Study

ByGroovy Green Dec 7, 2010

The NREL/GE Energy WWSIS study appears to be built on several questionable assumptions, each allowing the modeled system (of up to 30% wind/5% solar in the West Connect within the great Western Interconnect) to withstand the inherent difficulties of large scale renewable integration. The primary issue, consistent with my dissertation research, is that the authors assume that we can afford to massively overbuild the capacity of the system, adding the large percentages of renewable generation on top of newly built and existing plants. This allows one to be able to ignore the hourly or sub-hourly periods with extremely low output from renewables, as well as the days or weeks at a time during the summer when wind production is well below yearly average output levels. An ample reserve is at the ready to step in when renewables perform poorly. Secondly and equally important, the authors assume that coal plants, which have traditionally run in a base load capacity, will be able to be operated very flexibly – on par with combined cycle gas plants.

Utah Residents and Businesses Do Not Own the Water that Falls on Their Property

ByGroovy Green Sep 4, 2008

Like Colorado, Utah has laws on the books that make it illegal to collect rainwater that falls on one’s property. A Utah car dealer installed a cistern and rainwater collection system to feed a on-site car wash that has water recycling technology. This was in an attempt to “go green”. He was thwarted by the state government, and eventually had to work out a deal. Local residents who collect rainwater will not be bothered at this point because “there are bigger fish to fry”.

It Is Time for the US to Sell Its Highways?

ByGroovy Green Aug 28, 2008

It’s difficult to imagine a person not having heard the old axiom “Buy low, sell high”, and it is prudent advice when you are making financial decisions. It’s the second part of that adage that might warrant a look at our strategy for infrastructure improvement in this country. If you are looking to make the maximum amount of money by selling something you want to sell that something when it’s at its highest value. I wonder then, is it time for our government to sell its infrastructure? You know, since the effects of Peak Oil are beginning to make themselves felt, the value of the infrastructure developed to serve cars running on cheap oil will decline each year into the future; starting soon. Selling high might mean selling soon.

Now, I don’t think we should sell all of it, by any means. We should keep the ports and the train lines, but is now a good time to start selling our roads, highways and airports? There has been news recently of other governments selling their infrastructure, and considering the value of these items in an energy scarce future I would contend that their value will never be higher. In fact, there is already plenty of news about airlines facing massive losses. (And starting to charge for baggage, pillows and normal drinks) How valuable will an airport be if we don’t have airlines? Or what if the ones we do have are marginally profitable? I say it’s better to sell now while the full force of Peak Oil hasn’t quite made itself felt.

California Lawmaker Plans to Ban Incandescent Bulbs by 2012

ByGroovy Green Jan 31, 2007

This would be huge. I get a little “down” some times thinking that the environmental writers and blogs are just preaching to the choir. Then, once in a while something like this comes along and makes me believe that the memes that are kicked around in the blogosphere do make it to the public consciousness and yes, even to law makers.

The Greening of the EPA – 100 Percent Green Power

ByGroovy Green Sep 1, 2006

News from the EPA:

“EPA is the first and only major federal agency to purchase green power equal to 100 percent of its estimated annual electricity use nationwide.

As of September 2006, EPA will be purchasing nearly 300 million kilowatt hours (kWh) of green power annually in the form of renewable energy certificates (RECs) or delivered product. This amount is equal to 100 percent of the total estimated annual electricity consumption at all of EPA’s nearly 200 facilities across the country enough electricity to power 27,084 homes for an entire year.”

“616,279,179 pounds of carbon dioxide (CO2) emissions will be avoided annually the equivalent to removing 53,824 cars from the road for an entire year.”

I think this is good news, now if the rest of the U.S. Government will follow the example of the EPA we will see some huge changes… something tells me this may be a ways off.

When Will the Peak Perk?

ByGroovy Green Aug 23, 2006

Jeffery Brown throws out a challenge to the main stream media.

“Who among you is going to have the courage to step forward and “break” the story that the lifeblood of the world economy–net oil export capacity–is now declining?”

Mr. Brown says, “I estimate that oil exports from the top 10 net oil exporters are probably now falling at a double digit annual rate.”

He’s an independent petroleum geologist from Dallas by the way; not one of them economists that thinks you can put dollar bills in your gas tank and drive to work. I once told two smart friends of mine, an engineer and a medical student, that physics trumps economics and they said I didn’t understand how the world works. I don’t. But I do think that as oil is physically less available “laws” of economics are going to spin on their heads. Just a little prediction for you this afternoon. Here’s one more. It will be obvious that we’ve peaked in oil production by the end of 2006. It’ll take a few more years, two maybe, for the most optimistic of oil cheerleaders to admit so (read up on the history of the peak in production in the U.S. – 1971). Then, suddenly everyone will be saying, “Yeah, of course we’ve peaked. That’s what oil fields do- Duh!” But by then the scurry to find the next source of fuel for our mobile lifestyles and our transportation dependent economy will be on in full force. My favorite are the news headlines that read, “How Will We Fuel The Cars of Tomorrow?”, or, “Is Ethanol The Answer?” No ethanol isn’t the answer. It’s only suggested as a part of the solution because Iowa is the first stop on the road to the White House. It seems very few people are stopping to consider ways of living that require less driving. Supply-side solutions will not solve the problem of the declining rate of petroleum production.

Supreme Court To Decide If Bush Should Pay Attention To Emissions Control

ByGroovy Green Jun 26, 2006

Let’s see: a conservative court, a conservative congress, a conservative administration—something tells me this isn’t going to change anything. Up for discussion is whether or not the Bush Administration must regulate CO2 to combat global warming. A dozen states, several cities, and environmental groups have convinced the Supreme Court to take up the case–after a divided lower court ruled against them. The administration continues to push forward on the claim that carbon dioxide is not a pollutant under the Federal Clean Air Law–and even if it was, the EPA would have discretion over whether to regulate it or not. (Riiiggghhhttt…I’m sure the EPA in not influenced in any way by this administration) From the article,
“In their appeal, the states argued that the case ‘’goes to the heart of the EPA’s statutory responsibilities to deal with the most pressing environmental problem of our time’’ — the threat of global warming.

Something’s Fishy: Bush Creates Largest Ocean Preserve

ByGroovy Green Jun 15, 2006

President Bush did something for only the second time in his two-term presidency: he created a national monument. No, not with building blocks, but by invoking the 1906 National Antiquities Act and protecting over 139,000 square miles of largely uninhabitated islands, reefs, and atolls. Once under jurisdiction, the area would be protected by the strongest environmental laws available and actively monitored by state and federal agencies. While not certain to happen, a ban on commercial fishing in the area would “create the largest no-take marine reserve in the nation, second in the world only to the Great Barrier Reef.” Currently, there are ships in the area that use the coral-damaging “bottomfishing” technique to troll for snappers and seabass. Such a ban would help alleviate stress on the reefs and wildlife. While conservatives will certainly use this latest good news to prove to environmentalists that Bush is paying attention to the natural world, one should note that President Clinton created 19 national monuments and expanded existing legislation to set aside 5.9 million acres in the West. It’s nice to see that the administration is following in his footsteps by expanding existing legislation created under his tenure….at least until natural gas is discovered under the sea-floor.
