Climate Change is a Real Problem, but Current Renewable Energy Technologies Can’t Replace Fossil Fuels Without a Huge Nuclear Buildout. Because, Physics.

First, I’d like to stipulate that Climate Change is a real problem and human activities do contribute to it. But while it is a problem with which humanity needs to grapple, it isn’t an existential threat like a massive asteroid strike. Despite the hyperventilating media coverage, it will not end life as we know it in 2030 or in 2100. But we need to find sensible, cost-effective ways to deal with its consequences for the benefit of all. It makes a lot of sense to promote incremental switching to less carbon intensive energy technologies.

But kudos to Mark Mills, a fellow at the Manhattan Institute and a faculty fellow at Northwestern’s McCormick School of Engineering and Applied Science, for his article and his brilliant paper bringing to light a fundamental problem for those who want to attempt to solve the Climate Change issue with only the existing renewable energy technologies of solar, wind, and battery power.

Because of the limits of the laws of physics, it is simply not possible to do so without enforcing energy poverty on mankind through much higher costs, much less energy use per capita, and a lack of reliability of the power grid.

The New Energy Economy Is An Exercise In Magical Thinking

The incredible technological innovation brought to us by the “Moore’s Law” phenomenon in the world of semiconductors has fooled many eminent people into thinking it applies in other areas of research such as renewable energy technologies.

But whereas the physics of shrinking transistors and decreased energy needed to manipulate the idea of the numbers one and zero has enabled breathtaking change, the physics of manipulating and transporting physical matter does not conform to such exponential change.

The physics of energy is instead the realm of asymptotic effects, with big advances getting close to the barriers of physical laws which limit potential further progress greatly.

From The “New Energy Economy:” An Exercise In Magical Thinking by Mark Mills:

The physics boundary for silicon photovoltaic (PV) cells, the Shockley-Queisser Limit, is a maximum conversion of 34% of photons into electrons; the best commercial PV technology today exceeds 26%.

The physics boundary for a wind turbine, the Betz Limit, is a maximum capture of 60% of kinetic energy in moving air; commercial turbines today exceed 40%.

The annual output of Tesla’s Gigafactory, the world’s largest battery factory, could store three minutes’ worth of annual U.S. electricity demand. It would require 1,000 years of production to make enough batteries for two days’ worth of U.S. electricity demand. Meanwhile, 50–100 pounds of materials are mined, moved, and processed for every pound of battery produced.

Current renewable energy technologies cannot approach the energy density, cost, and reliability of fossil fuels and nuclear power. Those who want to do away with fossil fuels, especially without a massive buildout of nuclear power plants, have fallen prey to a fantasy.

The Average Person Won’t Accept Energy Poverty and/or Much Higher Costs for Energy

The Yellow Vest Protests in France began as a rebellion against an increase in the gas tax by average people, before the movement was corrupted by anti-capitalist perma-protesters. Average people the world over cannot and will not accept a purported solution for Climate Change that imposes huge financial costs and energy poverty on them. It is simply a non-starter.

And in the end, whether you are talking about trading carbon credits or instituting a carbon tax, all of the schemes pushed by the left, the media, and the scientific establishment are about raising the cost of energy use and thereby reducing the demand for it. People will simply not tolerate this.

A Way Forward

The scientific community has identified a real problem in Climate Change. But they (and the media and the left) have not done cost-benefit analysis. Their proposed solutions are not effective or acceptable. We should solve the problem with a common sense engineering mindset that takes into account the tradeoffs that real people will actually accept in their real lives.

Fortunately, accepting energy poverty and doing nothing are not our only options. We need a big investment in basic scientific research to come up with more advanced, energy dense, reliable, and economically competitive renewable technologies. In the interim, continuing to trade coal use for natural gas is a no brainer as this is substantially less carbon intensive. We also need a big buildout of nuclear power plants as nuclear is very energy dense, has zero carbon emissions, and can function as base load power, which renewable technologies (even backed up by batteries) cannot without a huge buildout of diesel backup generators, which is neither carbon friendly nor cost-effective.

A combination of natural gas as a long term bridge fuel combined with nuclear and renewables can work while we are doing the basic scientific research to come up with breakthroughs that can function as cost effective and reliable base load power replacements. And we should also pursue research into geo-engineering to mitigate the worst effects of Climate Change if such breakthroughs don’t come through in a timely enough fashion. Such an all-of-the-above approach is the only sensible way to proceed for the good of humanity.

Larry Fink’s Convoluted & Coercive Solution to the Problems of Indexing

I am delighted to find businesses that are ethical and treat their communities and employees well as a matter of doing good while doing well. These businesses are rewarded in the marketplace for being good citizens and profitable. They are also what might be described as “long term greedy,” realizing that helping their community thrive will help their business in the long run.

It is a virtuous circle, and the moral nature of business and capitalism has a long history of being addressed by greats such as Adam Smith in both The Wealth of Nations and The Theory of Moral Sentiments, and theologian Michael Novak in his book The Spirit of Democratic Capitalism.

Larry Fink Wants to Use Coercion to Recreate Capitalism in His Image

Now Larry Fink of ETF giant BlackRock has demanded that CEOs institutionalize the pursuit of their “social purpose” and the welfare of all so-called stakeholders, and put this on par with making a profit for shareholders while serving their customers.

This seems to me to be a convoluted and coercive solution to the problem a Progressive investor might have with indexing. But, it is easy to solve this problem without turning our companies into social welfare agencies. Become a stock picker or hire one to sell the stocks of companies that don’t meet your standards, and buy the stocks of companies that do. But this would be bad for BlackRock’s index business, so Larry leans on coercion to force companies to abide by his ideals while he can still rake in the fees his company gets from having $6 Trillion under management.

His plan would distract companies and employees from their productive functions to make them hold meetings, write reports, and push paper so that they can show they are keeping up with a new kind of enforced corporate political correctness. Something tells me that value creation and serving customers and shareholders would take a back seat. Larry would have made a great regulator during the Obama Administration.

Don’t Kill the Golden Goose or There Will Be No Wealth to Redistribute

One of the things that has always dumbfounded me is that the Left is so hostile to capitalism. The reality is that wealth must be created before it can be redistributed. So a sensible Progressive should want the economy to do well and create as much wealth and prosperity as possible so they will have it to redistribute. Killing the Golden Goose means no more golden eggs.

If Larry needs to assuage his conscience for being a rich capitalist, why not simply give his money to causes that support his values like Bill Gates and Warren Buffett are doing? I guess it’s cheaper to spout nonsense and hang on to his dough. It doesn’t sound like he is living up to his social purpose. But then I guess that depends on who the judge is.

Putting layers of useless guidelines, regulation, and bureaucracy on society so people are spending most of their time shuffling paper and ignoring their productive functions is a recipe for economic malaise at best. Forgive me if I hope people like Mr. Fink are kept as far from the levers of real power as possible.

Where Are the Pragmatists? Two Parties Filled with Fringe Lunatics Doesn’t Leave Voters a Decent Choice

One of the things that stuns me in our current political reality is that both sides are kind of nuts and dominated by their extremes. As bad as Trump is in many ways, at least his policies are focused on unleashing the creativity of the American people through cutting the suffocating regulation of the Obama years. If the Democrats could decide to be pragmatic and business friendly, they could really have something going. But the Far Left seems in control and wants to pursue the socialist policies that Hugo Chavez used to destroy a prosperous Venezuela. Doesn’t seem very promising.

The Wisdom of Charlie Munger: You Have a Moral Duty To Be Rational and Reasonable, and To Eliminate Your Own Ignorance


Learning from the experiences of others will put you on the path to a successful life with fewer unpleasant detours. Charlie Munger is perhaps the wisest man alive. He is a man who has dedicated himself to understanding the world and figuring out what works. Pull up a chair and learn how to think and how to live.

A Conversation with Charlie Munger and Michigan Ross – December 20, 2017:

“What the pupil must learn, if he learns anything at all, is that the world will do most of the work for you, provided you cooperate with it by identifying how it really works and aligning with those realities. If we do not let the world teach us, it teaches us a lesson.”

Investing Equals Decision Making Under the Condition of Uncertainty


Recently upon finding out I invest for a living, an acquaintance asked me to let her know if I see something coming in terms of a big market selloff, because she is approaching retirement and is scared of a bear market. This is both typical and mystifying to me in terms of the way regular folks tend to think. The reality is that I don’t know the future any more than she does. Investing equals decision making under the condition of uncertainty.

How an Investor Should Conceive of the Future

To properly conceptualize the future as an investor, you need to create different scenarios and assign subjective probabilities to them. You want a strategy and an approach that is robust against this subjective probability distribution of the future. You can’t control your returns, but you can control your risk profile. Managing your risk requires balancing the probabilities against their potential consequences. As Seth Klarman has said, nothing is more important than the ability to sleep at night.

How to Approach Investing In an Uncertain World

An investor’s task is to manage their assets and cash flows so they will provide for their needs over their lifespan. How do you do that? You estimate what you will need and make a plan that is likely to get you to a prosperous retirement. Don’t extrapolate to the best case scenario. Prepare for the worst and hope for the best. But, the big thing is to save and invest something. Anything is better than nothing.

If you are young and investing for retirement, Vanguard suggests putting aside 15% of your income toward this goal. If you can meet that number terrific. If not, 10% is a reasonable goal when getting started. If you get an employer match, so much the better as this will decrease the amount you need to contribute.

You also want to make sure that you have enough in savings and disposable income to cover your living expenses during the portfolio building stage of your investing life. You don’t want to get disheartened or need cash during a bear market and either stop contributing or sell your investments at a loss.

Munger’s Approach to the Market’s Vicissitudes

Charlie Munger has said that he doesn’t try to predict the ups and downs of the market, he just tries to swim better than the tide. He has also said if you aren’t able to endure a decline in the quoted price of your stocks by 50% and react with equanimity two or three times in your life, then you deserve the mediocre returns you are likely to get.

I always get a kick out of market pundits who talk about how uncertainty is high right now. Uncertainty is always high. While trends persist, often far longer than you may think, recessions and bear markets many times begin when the consensus is fairly cheery. Anyone who tells you they know what is coming next in the markets is a liar, and they are probably trying to sell you something.

“The question about selling a really great business is never. Because to sell off something that is a really wonderful business because the price looks a little high or something like that is almost always a mistake. It took me a lot of time to learn that.

A Survey of The Investing Horizon



So where do we stand with the stock market? The S&P 500 trades at just under 22 times trailing operating earnings according to Bloomberg …

… and 17.5 times forward earnings estimates according to J.P. Morgan.

So by these measures, the market is overvalued compared to 25 year averages. However, when the earnings yield is compared to current interest rates, the market is — if anything — rather cheap.

Ed Yardeni calls the current conventional wisdom the “2-by-2-by-2” scenario: 2% real GDP growth, 2% inflation, and a peak Fed Funds rate of 2%.

What If We Have Much Higher Interest Rates?

But much higher interest rates could upset the apple cart. While there are many reasons for lower potential growth and inflation — such as the aging of society — what if the conventional wisdom is wrong and higher growth and inflation cause a substantial increase in interest rates?

As the above chart shows, interest rates don’t generally have a negative effect on stocks until the ten year Treasury is above 5%. While it’s not impossible for rates to go higher than 5%, I see no reason for it to happen any time soon without much higher growth and/or inflation rates. And demographics and global trade would seem to keep a lid on both.

Runaway Inflation Seems Rather Unlikely

There are a lot of smart people who seem to think a normalized 4%-5% ten year Treasury yield is a reasonable planning assumption. For instance, Morningstar has a 4-5% ten year Treasury baked into its discounted cash flow (DCF) models to come up with their fair value estimates on stocks.

There is a lot of room between the current 2.24% on the ten year Treasury and a potential 5 handle. But with gradual Fed balance sheet reduction and possible higher growth from a tax cut or infrastructure package, the 10 year Treasury could easily reach 3%-3.5% over the next year or so — maybe even 4%. But that would require the Keystone Cops in Washington to get their acts together. And don’t forget the Fed is pushing in the other direction with higher short term interest rates because their outdated Philips Curve Model suggests inflation should be on its way any day now.

While commodities prices are mixed (weak ag prices/strong industrial metals), global trade should ease pressures on inflation. The official unemployment rate looks low, but there still seems to be some slack in the labor market with the low participation rate and wage growth below par. And to the extent wage pressures exist, companies will likely invest more in automation.

Maybe A Lot More Long Term Upside?

The good folks at Bespoke show that trailing 10 and 20 year stock market returns are still pretty lousy, which hardly seems an indication of a bubble ready to be popped.

And as this chart shows, we may well have entered a new secular bull market in 2013, which could bring huge gains over the next decade plus.

Can The Fed Control Its Urge to Cause a Recession?

So even though we’ve had a great 8 year run since the bottom in March of 2009, it seems we have room to the upside if the economy continues to do well. Unless we have a big geopolitical shock or the Fed hikes us into a recession. If we get a recession, we get a bear market. This is as close to a certainty as you will find in the markets.

While it seems everyone is looking for signs of the bottom falling out of the stock market, the data shows no bubble that I can see. Well, Tesla and Nvidia look rather bubbly but M&A and the IPO market are certainly not red hot. Big Cap Tech has had a great run, but they have real earnings and cash flows, and valuations are much more reasonable than during the bubble era. This is not about metrics like eyeballs and page views like 1999-2000. There is no sock puppet bullshit this time; by and large, they are real, substantial businesses.

It seems to me there is no need for a recession unless the Fed decides it wants to cause one by raising rates too much — so they can get the dry powder to lower rates in case of a recession, which they will likely cause by raising rates…

How To Plan For An Uncertain Future

If you are worried about a bear market, you should reduce your risk while times are good. Make sure you have enough liquidity so you won’t stop buying during a bear market if you are young and in the accumulation phase. And don’t sell into a decline!

Planning for your liquidity needs is even more important if you are in or near retirement. If you are worried about a coming bear market, you should sell down to the sleeping point now, when times are good. Don’t put yourself in a position to be a forced seller into a big decline. That only makes you fail to meet your long term goals while lining the pockets of guys like Warren Buffett and Seth Klarman.

I try to stay hunkered down all the time, and I plan for my liquidity needs as if a bear market will begin tomorrow. This is more sensible than to assume you will have some magical insight nobody else has that will enable you to sidestep the worst of a bear market.
