UN Forecast Year 2100 World Population At 10.9Billion. Only Nuclear Can Provide Needed Energy


The “UN 2019 Revision of World Population Prospects” report says that by the end of this century the world’s population will be about 10.9 people. What does this mean with respect to the UN goals of having only renewable power—wind and solar –and the elimination of fossil fuels as an energy source? 

The Pew Research Center analyzed the UN report and came up with some eye-opening observations.   China will begin to lose population by the end of this century.  India will have the world’s largest population, surpassing China.   Africa will have 4.3 billion people at the turn of the century, substantially more that the 1.5 billion it has in 2020.  And Africa’s average age will be 35. The World’s median age will be 42.

Look at this chart:

By 2100, Asia and Africa combined will be 9.0 billion of the forecast total world population of 10.9 billion. We can expect that the really undeveloped populations of the world will be demanding a standard of living approaching that of Europe and North America. 

China and India have already launched programs to achieve a very much improved standard of living for their people.  Africa will surely do the same and with a relatively young population they will be aggressive.  That standard of living will only be realized through energy.

It will not come from renewables.  It probably cannot be fully realized by fossil fuels.   It will have to come from nuclear energy.  Ultimately, nuclear will dominate the energy sector.  

For the US, economics are causing some shutdowns of nuclear plants as natural gas generates energy at a lower cost.  In the long run, nukes should be the lowest cost reliable energy.

However, there are several nukes that are being shutdown because a governing body does not like them.  These are bad choices.

Germany seems to have an irrational fear of nukes that were prompted by the Japanese Fukushima nuke plants being flooded by a tsunami.  When was the last time a tsunami hit Germany?

It is my opinion that the greens opposition to nukes is that the nukes have the potential to solve the energy problem. Many leaders of the green movement have publicly announced that their goal is a one-world socialist government based out of the UN. They would prefer an energy limited world where they would be in charge.   Nukes could solve the energy problem, destroying their dream.  

Ok, will these population estimates prove-out?  Will Ebola wipe out millions of Africans?   Will there be a war or wars that slash these estimates?   Could the expectations for lower fertility be wrong and the world population grows even larger?   Of course, I don’t know answers to any of those questions.  But for the moment, I am assuming these estimates are going to be accurate.

Renewables Are Better At Creating Jobs Than At Creating Energy


Anericanexperiment blog posted”Energy Industry There to Produce Energy, not Jobs” written by John Phelan..The author begins by quoting Gregg Mast of Clean Energy Economy Minnesota who is boasting about clean energy jobs growth.  Mast says:

 “The fact is,the number of clean-energy jobs has grown every year since the release of the first Clean Jobs Midwest-Minnesota report in 2016, and these good-paying jobs have been added at a faster pace than the statewide average.”

 

Countering Gregg Mast’s boast,  Phelan responds by saying:

“This might sound like great news, but there is something missing from this celebration. It is something vital. Indeed, from an economic point of view, it is the most vital thing of all: How much energy are these workers actually producing?  Increasing productivity — the ratio of outputs produced to inputs used — is key to economic growth and raising living standards”.

So, how productive are these new clean-energy workers? How much energy does each produce?  Sadly, the answer seems to be “not much.” According to data on electric-power generation by primary energy sources from the Energy Information Administration and figures for employment in each sector from the U.S. Energy and Employment Report, we can see that, in 2017,   the 412 workers employed in Minnesota’s natural-gas sector produced an average of 16,281 megawatt hours of electricity each. For coal, the figure was 13,230 megawatt hours produced for each of the 1,722 workers employed in the state.

But for renewable wind and solar, the numbers are far less encouraging. In terms of megawatt hours produced per worker, Minnesota’s wind sector came in a somewhat distant third. Each of the 1,966 workers here generated an average of just 5,665 megawatt hours in 2017. This was just 43 percent of the amount of electricity a Minnesota coal worker produced annually and 35 percent of that produced by a natural-gas worker.

For solar, the numbers are even worse. In 2017, each of Minnesota’s 3,800 solar-energy workers produced an average of just 157 megawatt hours. This was just 1.2 percent of the energy produced by a coal worker and only 1 percent of that which a natural-gas worker produced.

The chart below illustrates the above:

 

 

 

In terms of that vital ratio of outputs (energy generated) to inputs (number of workers), wind energy is a low-productivity sector compared to natural gas and coal. Solar is even worse. Piling more inputs into these sectors when they could be more productive in other sectors lowers productivity and economic welfare. This is certainly not something to be celebrated — from an economic point of view, at least.

Mast and Clean Energy Economy Minnesota need to remember that the point of an energy industry is to generate energy, not to generate jobs.

A response by supporters of wind and solar is that there are workers out there insulating homes.  How many of solar’s 3800 jobs are insulating homes?

Paris Agreement and Paris Agreement Hollow Echos


Virginia goes Don Quixote 

State will defy Trump, double down on renewables and CO2 reductions – and hurt poor families.  By Paul Driessen

Democrat Ralph Northam had barely won the Virginia governor’s race when his party announced it would impose a price on greenhouse gases emissions, require a 3% per year reduction in GHG emissions, and develop a cap-and-trade scheme requiring polluters to buy credits for emitting carbon dioxide.

Meanwhile, liberal governors from California, Oregon and Washington showed up at the COP23 climate confab in Bonn, Germany to pledge that their states will remain obligated to the Paris climate treaty, and push ahead with even more stringent emission, electric vehicle, wind, solar and other programs.  Leaving aside the unconstitutional character of states signing onto an international agreement that has been repudiated by President Trump (and the absurdity of trying to blame every slight temperature change and extreme weather event on fossil fuels), there are major practical problems with all of this.

Germany-to-miss-co2-reduction-targets  By P Gosselin on 6. December 2017

The latest forecast shows snow and cold moving across much Germany this weekend, again. Despite Germany ‘s ruddy CO2 emissions, winter keeps coming.

German public broadcasting, here for example, reports today that despite all the green, climate-preaching, Germany will miss its 2020 CO2 reductions by a mile. More embarrassingly, the country has not reduced its CO2 equivalent emissions in 9 years when 2017 is counted in the statistics.

From the New York Time: “What Happened (and Didn’t) at the Bonn Climate Talks

The New York Times puts a happy face on the Bonn meeting on the Paris agreement,  it is clear that virtually none of the parties are meeting their commitments:

Even Without Paris Agreement, U.S. Leads World in Declining Carbon Dioxide Emissions: “While the decision to pull out of the deal had diplomatic consequences, the U.S. has dramatically lowered its carbon emissions in the last year, largely without government mandates. These emissions reductions came as the result of price drops for both natural gas and solar panels. How significant this reduction is, however, demonstrates the challenges of gauging emissions on a global scale.

Paris Agreement—Are the Germans Leading the Developed Nations?


It looks like Chancellor Merkel believes that now that Ex-President Obama has been replaced by President Trump, she is the developed nation’s leader regarding the Paris Agreement.

So, is Germany leading the way? The Chancellor’s plan “Energiewende” (transition to renewable energy) has set out goals with a timetable to reduce CO2 emissions and switch the national’s energy supply to renewables that can replace fossil fuels. The table below summarizes these goals:

The Greenhouse gas emissions reduction goals are spelled out in the table. The goals, for the years 2014 through 2050, are shown as an amount of reduction based away from the1990 emissions of CO2.  That was the year of the reunification of East and West Germany.  The goal in 2050 is a minimum reduction of greenhouse gases of 80 to 95%.

Can Tesla Survive The Loss Of Subsidies?


Three years ago, The Los Angeles Times posted “Elon Musk’s growing empire is fueled by $4.9 billion in government subsidies”. I have not seen a summary of the current total of Musk’s subsidies but it is certainly more than $4.9 billion now. When The LA Times speaks about an “empire” it included Tesla, Space X and Solar City—all Musk controlled businesses.

This discussion will focus on the Tesla electric vehicle (EV) business.

Subsidies start with the Federal Tax Credit of $7,500 given to each buyer of a Tesla EV.  (Every EV maker gets the same treatment.).  California also provides a $2500 subsidy per car.

The following is from the LA Times posting:

“Tesla has also collected more than $517 million from competing automakers by selling environmental credits.  The regulation was developed in California and has been adopted by nine other states.”

These regulations require that companies selling automobiles must also sell a certain percentage of EVs.  Sales of an EV gives the seller environmental credits.   Manufacturers are penalized for not selling enough EVs and must buy credits to offset their failure. Because Tesla sells only EVs it gets a lot of credits which they sell to the other car makers.

The following 2016 video discusses what the Wall Street Journal thinks subsidies mean to the Tesla’s bottom line: (Please excuse the 15 second commercial.  When video ends click back to this page.)

Paris Agreement Doomed By Projected Coal Based Power Plants


The Global Warming Policy Forum (GWPF) posted “Forget Paris—1600 New Coal Power Plants Built Around The World.”  The GWPF provides the chart below that focuses on Europe, Asia and Africa using data from Coal Exit.com:


 

 

 

 

As you can see, China already has 2,363 coal based plants and expects to have 1,171more.  It comes as no surprise that China and India are major users of coal based power currently and they will be the major builders in the future.  No other country is even close.  It is illustrative to see that European nations are forecast to be increasing coal based capacity, not reducing it as their none too subtle “holier than thou” attitude would suggest.

Why Did ExxonMobil Lobby To Stay In The Paris Agreement?


ExxonMobil lobbied President Trump to stay in the Paris Agreement. Can you figure out why that company would wish to do so?

Here are some pickings from the most recent ExxonMobil global energy forecast:

·         Total energy demand by 2040 will be 25% higher than in 2015.

·         Global energy supply in 2040 will be 55% from oil and natural gas. Wind, solar and biofuels will supply only 4% in 2040.

·         Coal use will decline but will still be the third largest supplier of global energy.

·         Global electrical energy demand for transportation will only be 2% of the total global energy demand in 2040.

·         Wind and solar electricity supplies will approach 15% of total electrical energy supply by 2040

·         Although utilization improves over time, intermittency limits worldwide wind and solar capacity utilization to 30% and 20% respectively.

·         By 2040 US and Europe combined CO2 emissions will be about 8 billion tonnes.  The total global emissions in 2040 will be about 36 billion tonnes,

·         Electric cars are a very high-cost option, at about $700/tonne of CO2 avoided.
