Tesla and the Transformation of Electric Cars

Tesla garners as much media attention as do the Big Five of the digital economy—Apple, Alphabet, Microsoft, Amazon, and Facebook. Tesla’s valuation now exceeds those of major U.S. automakers, and is now positioned to compete in the highly contested category of mid-to-upper priced vehicles. But the resurgence of electric vehicles (EVs) is not just an American phenomenon. It is an even bigger story in a few other countries. Here are a few recent developments.
  • Tesla’s Model 3 were delivered in July to the first 30 customers, and the Fremont plant expects to produce 500,000 cars annually from next year
  • U.K. said it would ban the sale of new gas or diesel vehicles by 2040, and will phase out all cars with internal combustion engines by 2050
  • France said it would stop sales of diesel and gas vehicles by 2040
  • China, whose citizens purchase nearly half of the world’s electric vehicles, has mandated that EVs must make up 12 percent of each manufacturer's sales by 2020
  • Big cities like Athens, Paris, and Madrid have announced they will ban diesel cars by 2025
  • The European Union regulation on passenger cars[i] limits the continent’s average new-car CO2 emissions at 95 grams per kilometer. To avoid the Euro 95/g per car exceedance penalty, manufacturers have little choice but to expand their EV fleets.

Why Dow 20,000 Is So Boring?

The financial media cannot stop tweeting about the possibility of Dow Jones Index breaching the 20,000 mark. Rising stocks boost public confidence and sense of affluence. Yet, for the broad population, the rising market index doesn’t seem to generate widespread excitement. Why is that? A possible reason is: lower direct participation by the public in market activities, both in listed securities and new issues (IPOs).

(Source: Wall Street Journal)
An excellent write up last week in the Wall Street Journal (“America’s Roster of Public Companies Is Shrinking Before Our Eyes”) highlighted the declining pace of IPOs. Tech IPOs have been particularly lackluster. In 2016, technology companies raised only $4.3 billion from public markets, versus $19 billion from private equity investors. Overall, 111 companies went public on U.S. exchanges, raising $24.2 billion. That is the lowest dollar volume since 2003, according to Dealogic.

 On the other hand, Lise Buyer made the case in Fortune (“Why 2016 Was Actually a Pretty Good Year For Tech IPOs”) that an investor who bought all tech 2016 IPO stocks at debuting prices would have done well, netting over 35% returns. Though this was a volatile year, many of the IPO stocks ended in the black after the year-end market rally.

Ivanpah – A Sad Postscript

Sadly, my worst fears about the Ivanpah’s projects under-performance came true (see the blog “Operational Hiccups at Ivanpah”).  The project owners BrightSource, Google, and NRG have requested financial relief from the federal government.  After going live in February, the project has accumulated payment deficits of over $400M on its loan repayments.

According to various media reports, the 392MW project has generated only about a quarter of the energy it expected to produce.  Miscellaneous reasons have been offered for financial troubles – including delays in processing tax credits and low revenue due to cloudy skies.

It is ridiculous to blame the sun.  As my analysis in the previous blog bears out, the concentrated solar facility was underperforming on the very days when the PV energy output in surrounding region was high.  The sun is not the culprit – the project design and engineering is.

There is another twist in the tail here.  Not all of its energy comes from the sun – it also burns natural gas to supplement power generation.  Reportedly a higher portion of the power is coming from natural gas than originally designed.  In other words, the true conversion of solar energy to renewable power is even worse than the data suggests.

It remains a mystery – why do smart and committed people make bad decisions, ignore previous learnings from several failed CPV projects, and then try to hide the bad outcomes with ridiculous explanations?

Operational Hiccups at Ivanpah Solar Worry Me

The world’s largest solar thermal facility was brightly unveiled to the American Public in Ivanpah, CA by the U.S. Energy Secretary Ernest Moniz on February 13.  The project, designed and sponsored by BrightSource Energy and owned by BrightSource, NRG Energy, and Google, cost $2.2 billion and received $1.6 billion federal loan guarantees through the Department of Energy.

NRG Energy tweeted: “Thrilled to announce: Ivanpah is fully operational & delivering solar power to California!”  And Ernie Moniz exclaimed: “This is fantastic news! I'm hoping this is only the beginning of many to come. This is the type of energy we need.

But the operational data negate this optimism, and I’m worried that this concentrated solar project may not fare much better than several other projects that have not turned out well.  Generally, operational complexity and risk do not deter me.  But when a project utilizes public money and goodwill to absorb risks and generate private profits, even a partial failure could become a lightning rod for public criticism.

Energy Productivity is Key to Profits and Growth

“If energy efficiency improved by 2% a year, the entire global population at the turn of this century could live at the American standard of living with less energy than we use today.”  Dr. Richard Muller, speaking at WAVE event “GENIUS: Ideas and People that Move Us,” makes no apologies for being a capitalist, one who believes that “a solution which is not profitable is not sustainable.”  The key to profitable investing, he believes, is efficiency in the use of energy and resources.  Or, as he is more likely to say, energy and resource productivity.

At WAVE, we recently hosted Dr. Richard Muller, a Berkeley physicist and a leading authority on climate science.  An acclaimed author of ten books including “Energy for Future Presidents,” and a researcher whose projects have led to two Nobel Prizes, he initially earned (dis)repute for pointing out inconsistencies and inaccuracies in climate research.  Later, he designed and led the most comprehensive research on global warming, concluding that many solutions embraced by environmentalists, such as the electric cars and solar thermal energy, are futile.

Electric Cars – Are the Savings Real?

The government website contends that it costs about 3 times less to drive an electric vehicle.  An eGallon costs $1.22 versus $3.56 for a gallon of gas.

I’m not convinced.  I’d rather drive a hybrid car rather than an electric car.  Here is why.

Embedded in the computation for eGallon are assumptions that do not hold true for me.  It assumes a low cost of retail electricity, 12.3 cents/kWh versus my actual cost of about 19 cents/kWh.  It also assumes that a comparable gasoline car drives 28.2 miles per gallon.  Now, according to the government data (, a comparable hybrid car drives about 44 miles per gallon.  Adjusting for these two assumptions, an eGallon will cost $2.94 versus $3.80 for me in Massachusetts.

Technology is Not Enough - A Parable

Every day, I see hundreds of cars moving.  Why do the cars move?

A simple question like unlocks a series of esoteric thoughts to a physicist like me.  Generations of scientific discoveries help us understand and explain the car’s movement.  You have the laws of motion, Thermodynamics, energy conversion and conservation, friction, electromagnetism and electricity, quantum mechanics that allow us to design chips at nanoscale, and gravity and general relativity whose understanding is essential for accurate operation of the GPS.  Nearly all of our scientific knowledge of physical worlds is neatly encased in the movement of the car.
