Friends Of Science Engineering Critique Of WWS’s Plan For Global Decarbonization


The previous posting, examined the study “A roadmap for rapid decarbonization” published in the Science magazine,  and discussed the major obstacles the warmers face in their attempt to persuade the politicians and the voters to undertake decarbonization.  And do it rapidly.   You may not think thirty years is rapid, but convincing 8 billion people to wipe out the present infrastructure and substitute a new one using as yet unproven methods in 30 years, is moving at a breathtaking speed.

The above noted study, is not the only one that has looked at a way to satisfy the Paris Agreement of holding the global temperature to max.2 ºC rise, with a goal of 1.5ºC rise.  A study by 100% Clean and Renewable Wind, Water and Sunlight (WWS) led by Jacobson, Delucci , et at. is, on the surface (number of pages of detailed discussion), more elaborate than the previous posting.  This  WWS roadmap calls for an 80% reduction of fossil fuels by 2030!  Only 13 years away.

The WWS study is an all-sector roadmap that is said to show how 139 nations could jointly hold the temperature rise to no more than 2ºC.

Friends of Science critique the WWS study with a response titled “WHY RENEWABLE ENERGY CANNOT REPLACE FOSSIL FUELS BY 2050” .  Michael Kelly, Professor of Electrical Engineering at Cambridge says: “Humanity is owed a serious investigation of how we have gone so far with the decarbonization project without a serious challenge in terms of engineering reality”.

That’s what guides this critique.  The critique illustrates the enormous number of new renewable facilities needed, the time necessary to put  these facilities in to operation and the amount of space they require.  It is awesome.

Dr. Judith Curry Believes the RoadMap to Zero CO2 Emissions Is Infeasible.


 

 

I have promised some critical views from skeptics regarding the Paris Agreement Roadmap to zero CO2 emissions by 2050.  If you need to get up to speed regarding  the Paris Agreement Roadmap,  please review my last two postings. 

Let’s begin with Judith Curry’s thoughts on this topic from her posting of 25 March titled A roadmap for meeting Paris emissions reductions goals”.

JC reflections

Apart from the issues raised in this paper, there are several other elephants in this room:  there is growing evidence of much smaller climate sensitivity to CO2; and even if these drastic emissions reductions occurred, we would see little impact on the climate in the 21st century (even if you believe the climate models).

I think that what this paper has done is important:  laying out what it would actually take to make such drastic emissions reductions.  Even if we solve the electric power problem, there is still the problem of transportation, not to mention land use.  Even if all this was technically possible, the cost would almost certainly be infeasible.

As Oliver Geden states, its time to ask policy makers whether they are going to attempt do this or not.  It seems rather futile to make token emissions reductions at substantial cost.

Deciding that all this is impractical or infeasible seems like a rational response to me.  The feasible responses are going with nuclear power or undertaking a massive R&D effort to develop new emission free energy technologies.  Independent of all this, we can reduce vulnerability from extreme weather events (whether or not they are exacerbated by AGW) and the slow creep of sea level rise.

 

Dr. Curry’s remarks are very succinct.  To be a success, the roadmap requires many inventions that to date have been sought after but not delivered.  And she points out, as noted in this blog on a number of occasions, the climate sensitivity used by the warmers gives temperature increases that are unsupportable.  This roadmap is necessary in large part because it is predicated on those exaggerated temperatures the climate models produce.  That is Dr. Curry’s “elephants in the room.”

And she thinks it is way too costly.  I believe she is spot on.

Some EV Sales Improvement, But Still Way Below Obama Forecast


ev-for-postingHave you been keeping up with the car buying public’s interest in electric vehicles (EV)? The many models of EVs that are on the market are quite astonishing.  Nearly all the manufacturers have a model or two.  The sales are still well below the Obama Administrations projections.  But 2016 brought some joy to the makers of plug-in EVs.

Probably most of you that are reading this know about the different versions on the market, but for those that have not been following EVs closely, let me give you some guidance.

The Toyota Prius has been the sales leader. Later on, the Chevy Volt and the Nissan Leaf came on the scene but they have not equaled the Prius sales volume.  Those three vehicles represent the three major categories of EVs.

The Hybrid (HEV) is a vehicle that has both batteries and an internal combustion (IC) or diesel, fossil fuel powered motor to propel the vehicle. The batteries are not charged by an external plug-in arrangement but are charged by the onboard motor. The Prius is a HEV

The PHEV has both a IC or diesel motor and batteries, but in this category the batteries are charged by plugging into an external power supply.     The Chevy Volt is a PHEV.

The BEV vehicle has only batteries for motive power and those batteries are charged from an external power supply.  The Nissan Leaf is a representative of this category as are the Tesla and the GM Bolt.

Want-To-Be Warmers Are Only Getting Part Of The Story


 

This posting uses an article from the Cosmopolitan magazine. Not a place where you would expect to find something about global warming. The title of the piece is “8 Signs You’re Not the Environmentalist You Think You Are” by Yvette d’Entremont. It is not too profound but it has a lot of honest values that most would be environmentalist never are exposed to. I have extracted just pieces of the author’s reasons why they have been misled. If you read all of her article, she makes some more good points

The following are the eight signs:

1. You buy only organic.

Organic is definitely not better for you, and it uses older, dirtier farming techniques that are, across the board, not as environmentally friendly. Contrary to rumors, organic farming uses pesticides, in some cases equally toxic pesticides that need to be applied more frequently.

Sales Of EV’s Are Not Impressive.


cartoonevforseptblogSales of electric vehicles (EV) jumped in the second quarter of this year. This was enough to convince Real Clear Energy to post “Surge in EV Sales Bucks Cheap Gasoline, Broader Auto Industry Trends”. The posting says that while President Obama’s goal of 1 million EV’s on US roads by 2015 was not met, it was only about half that number in 2015, the surge “gives reason for fresh optimism about the future…..” EV Sales in the first half of 2015 were 70,296 versus 2016 first half sales of 99,634—a 42% change. That looks pretty impressive in the abstract.

However,  EV sales need to be evaluated versus all US automobile sales

Detailed Data for sales in August are readily available but June 2016 detailed data are behind a pay wall.  In reality the exact numbers are not significantly going to change the fact that EV sales were about 1..2% of total sales.  YCharts forecast annual sales based upon  auto sales by using the current month’s actual sales.  In June , half of the year, the Y chart number for total sales was 17.09 million automobiles.  This number counts cars and light truck and it includes EV sales in this number.  The 2016 auto sales  for the year based upon August July sales was18.15 million. Because the biggest sales months are in the fall of the year,  the official forecast for 2016 sales is 18.75 million.

Anyway,  if the annual forecast at the end of June was 17.09  roughly the year to date sales for the first six months sales would have been about 8.5 million.

The math:        0.1 million EVsales /8.5 million total sales = 1.2% of the total sales were EVs.

Real Clear Energy really has to be reaching to say that this gives them “fresh optimism.”

A hat tip to David Middleton for this story line based upon his posting in WUWT titled “Green math must be a Common Core product“.  I have modified it because I believe his calculation was erroneous. He arrived at number of 0.6% rather than what I believe is the correct number. Middleton’s conclusion however  is unchanged by my calculation of 1.2%.

“California Dreamin’” Or Perhaps Hallucinatin’.


California, always trying to be an environmental leader, has recently enacted SB 350 which will require that, by 2030, electrical utilities must get 50% of their power from renewable resources. The bill also requires greenhouse gases emissions (GHGE) be reduced by 40% by 2030 and 80% by 2050 versus the carsonhighwayimages1990 GHGE baseline. Dropped from the bill were measures to compel a 50% reduction in petroleum use by 2030.

These reductions are more stringent than those that failed to get accepted by the nations of the World at the COP21 meeting in Paris. California against the world. Further, even if these SB350 mandated changes are met, they will be too small to even be measureable. That is the definition of futility.

Tenth International Conference on Climate Change


global-warming-south-carolina-political-cartoonI attended the “Tenth International Conference on Climate Change” held in Washington, DC on June 11-12, 2015.   It surpassed my expectations. The panel presentations were uniformly excellent. While I consider myself to be reasonably well informed regarding this topic, I realized that are certain important areas of which I knew little.     For example I learned many things about the way the EPA operates that makes me very angry. Several of the current Republican candidates for President have announced that if they are elected they plan to shut down the EPA and let the State’s environmental groups handle these issues.   I plan a future posting about this topic.

Mainly the Conference covered global warming science. However there were some tributes to contributors who have made an impact.   One interesting presentation was Christopher Monckton’s defense of Dr Willie Soon.

The entire conference is on video. It can be seen by clicking on this link
