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.

ExxonMobil Ripped At Stockholders Meeting


I have come across a posting on JunkScience titled “Milloy rips at ExxonMobil management for supporting climate alarmism” by Steve Milloy.  The content of  his address at the recent ExxonMobil stockholders meeting can read by clicking here.

Here is a part of what Milloy said this at the meeting:

“My fellow shareholders, we can defeat the activists as they:

  • Hype the climate hoax;
  • Lobby governments for anti-oil policies;
  • Force investment funds to divest from Exxon;
  • Campaign to stop oil production; and
  • Pressure regulators to force companies to write down their reserves.

A handful of others and I have been fighting these anti-capitalist activists for decades.

Our efforts helped produce a President who knows climate hysteria is unfounded and who wants the oil industry to thrive. “

Read  Milloy’s address, or listen to it on the YouTube (I found that difficult so that is why I have put the transcript in.)

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.

Batteries May Not Solve Renewable Energy Non-Dispatchable Problem


The greens believe that solar and wind farms will be the way to eliminate the use of fossil fuels.  The reality of today’s solar and wind farms is that these sources are unable to be worked into the grid because of their unreliability. It is necessary to install natural gas powered turbines or diesel power generation along with the solar and wind farms. The fossil fuel units are required to generate electricity to balance the power grid when the sun is not shining and the wind is not blowing.

The greens’ solution is a battery system that stores enough energy to eliminate the need for fossil fueled energy backup systems.  Much research effort is underway to develop a battery to accomplish this objective. To date nothing stands out as a likely candidate for the job. 

But even if a battery that can do the job and does not cost too much emerges, there is another problem.   That problem regarding solar farms is discussed in an American Thinker posting by Viv Forbes titled “Batteries: Another green scam”.  The following is from that posting: 

The idea of producing reliable grid power from intermittent green energy backed up by batteries looks possible in green doodle-diagrams, but it would be absurdly inefficient and expensive.

Solar works a six-hour day

Consider a solar panel rated to collect, say, 100 units of energy per day at full capacity, in full mid-day sunlight, with a clean panel, properly aligned to face the sun.

No solar energy arrives overnight, and only minimal amounts arrive during the three hours after dawn or before dusk.  That means that solar energy can be collected for only about six hours per day, providing it is not cloudy, raining, or snowing.  No amount of research or regulation will change this.  The solar energy union works only a six-hour day and takes quite a few sickies.  So instead of feeding 100 units of energy per day into the grid, at best, the panel supplies just 25 units.

Can the addition of batteries give us 24/7 power from solar?

To deliver 100 units of energy in 24 hours will require an extra 75 units of energy to be collected, stored, and delivered by the batteries every sunny day.  This will require another three solar units devoted solely to recharging batteries in just six sunny hours.

Cloudy and wet days are what really expose the problems of solar plus batteries.  (This is why isolated green power systems must have a diesel generator in the shed.)

To insure against, say, seven days of cloudy weather would require a solar-battery system capable of collecting and storing 700 units of energy while still delivering 100 units to consumers every day.  However, if several consecutive weeks of sunny weather then occur, this bloated system is capable of delivering seven times more power than needed, causing power prices to plunge, driving reliable generators out of business, and wasting the life of solar panels producing unwanted electricity.

Solar energy obviously does best in sunny equatorial deserts, but that is not where most people live.  And the huge Desertec Solar Power Dream for the northern Sahara has failed.

Media Not Providing The Real Facts About Wind And Solar Energy


It is likely that a great many people in the US have been led to believe that solar and wind play significant roles in supplying domestic energy.  Further and even more incredibly they are led to believe that solar  and wind will replace fossil fuels in the not too distant future.  The Paris agreement demands that no fossil fuels  be used after 2050

I am too old to make it to 2050,  so I will not be around to see if no fossil fuels are being used at that time.  If you make it to 2050, I will bet that fossil fuel will still be used.

The Energy Information Administration’s(EIA)**, chart on the primary energy sources for the year 2015 is shown below.

Petroleum, natural gas, coal, renewable energy, and nuclear electric power are primary sources of energy. Electricity is a secondary energy source that is generated from primary sources of energy.

 

Note that renewable energy is only 10% of total energy produced in the US.  And of that 10%, solar is 6% and wind is 19%.   Putting the solar and wind as a percent of the total energy consumed in the US has solar at 0.6% and wind at 1.9%.  So, in  2015 only 2.5% of the US energy came from those two sources. Is this compatible with what you are learning from the media?   And those two are the ones that the greenies are banking on to replace coal, natural gas and petroleum.  And though it is counterintuitive, the warmers want to shut down the nuclear plants as well.

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.
