There are many kinds of climate change denial.  A minority of people deny that climate change is occurring or serious.  This is classic denial.  But a much more common and insidious form is all around us: accepting that the problem is real, but pretending that solutions are at hand, underway, or not very difficult.  By pretending that Elon Musk’s solar shingles or whiz-bang batteries can provide easy solutions, these people essentially deny the need for rapid, aggressive action.  They are wrong.  We are not solving the climate change problem.  At worst, record high rates of fossil fuel use are locking us into civilization-threatening levels of warming.  At best, we are proceeding toward solutions, but far too slowly.   What we must stop denying is the need for rapid, aggressive, transformative action.

Each year British Petroleum (BP) releases a report and dataset detailing global energy supply and demand.  The data includes each nation’s production and consumption of coal, oil, natural gas, hydroelectricity, and other energy sources.  Some data extends back to 1965.  BP provides one of the most important sources of energy information.  The company’s newest dataset—updated to include 2016—was released June 13th.  BP’s data shows that 2016 was another record-setting year for fossil fuel use: 11.4 billion tonnes of oil equivalent.  See graph above.  That same data shows that the rate of solar panel installation is slowing in nearly every nation.

The three graphs below are also produced from recently-updated BP data.  They show the amount of annual increase in the production and use of solar PV electricity in various countries.  This is approximately equal to the annual amount of new capacity added, but it further takes into account how much of any new capacity is actually being utilized.  The North American, Asian, and European nations featured in the graphs together host 92 percent of the world’s installed solar generation capacity.

The first of the three graphs shows how much solar PV production/ consumption increased each year in selected EU countries over the past 17 years.  It’s bad news: the rate of additions to solar power consumption peaked in 2012 and has fallen dramatically since then.  The graph shows that the rate at which EU countries are installing solar panel arrays has collapsed since 2012.  Progress toward renewables is decelerating.

Annual PV production and consumption additions, 2000 to 2013, EU countries

Further, note how each individual country accelerated its installation then slowed.  Spain, represented by the green bars, ramped up installation of solar panel arrays in 2008 and ’09.  After that, solar PV additions to Spain’s grid fell sharply, and rallied in only one year: 2012.  Germany’s solar installations followed a similar trajectory.  In that country, annual increases in solar power production and consumption grew until 2011, then began falling.  Additions to solar power production and consumption in Italy peaked in 2011 and have been falling ever since.  Nearly every EU nation is slowing the rate at which they add solar power.

The next graph shows production/consumption additions in the US and Canada.  The rates of new additions in those countries also appears to be sputtering.


The final graph shows the rate of production/consumption increases in China, India, Japan, and South Korea.  Clearly, capacity and consumption are rising rapidly in Asia.  But note that rates of installation are increasing only in China and perhaps in India.  One EU-based analyst told me that in recent years China ramped up solar-panel production to serve markets in the EU and elsewhere.  But when demand in those markets contracted, faced with a glut of panels coming out of Chinese factories, the government there pushed to install those panels in China.  Perhaps that isn’t the entire story.  It may be that China’s world-leading solar install rates are partly caused by a visionary concern for the environment and the climate, and partly by the need to absorb the output of Chinese PV panel factories left with surpluses after other nations failed to maintain installation rates.


Together, these four graphs tell a disturbing story.  Instead of accelerating rates of solar panel installations, we see stagnation or decline in nearly every nation other than China.  This comes along-side record-high fossil fuel use and record-setting CO2 emissions.  We’re failing to act aggressively enough to decarbonize global electricity systems and we are largely ignoring the project of decarbonizing our overall energy systems.  Rather, we’re increasing carbon emissions.  And as we do so, we risk slamming shut any window we may have had to keep global temperature increases under 2 degrees C.

Happy motoring: Global automobile production 1900 to 2016

Graph of global automobile production numbers, various nations, historic, 1900 to 2016
Global automobile production (cars, trucks, and buses), 1900-2016

This week’s graph shows global automobile production over the past 116 years—since the industry’s inception.  The numbers include car, trucks, and buses.  The graph speaks for itself.  Nonetheless, a few observations may clarify our situation.

1.  Global automobile production is at a record high, increasing rapidly, and almost certain to rise far higher.

2. Annual production has nearly doubled since 1997—the year the world’s governments signed the Kyoto climate change agreement.

3. China is now the world’s largest automobile producer.  In terms of units made, Chinese production is double that of the United States.  This graph tells us something about the ascendancy of China.

4.  Most of the growth in the auto manufacturing sector is in Asia, especially Thailand, India, and China.  In 2000, those three nations together manufactured 3 million cars.  Last year their output totaled 34 million.  After 67 years of production, Australia is about to shut down its last automobile plant.  Most of its cars will be imported from Thailand, and perhaps a growing number  from China.

5. Auto production in “high-wage countries” is declining.  As noted, the Australian industry has been shuttered.  US production is down 5 percent since 2000, and Canadian production is down 20 percent.  Over that same period, production fell in France, Italy, and Japan, though not in Germany.  Since 2000, auto production increases in Mexico (+1.7 million) are roughly equal to decreases in Canada and the US (-1.2 million).

6. There are some surprises in the data:  Turkey, Slovakia, and Iran all make the  top-20 in terms of production numbers.

Electric cars are coming…  Fast!

Graph of the number of electric vehicles worldwide and selected nations
Increase in the stock of electric vehicles: global and selected nations

When- and wherever it occurs, exponential growth is transformative.  After a long period of stagnation or slow increase, some important quantity begins doubling and redoubling.  The exponential growth in cloth, coal, and iron production transformed the world during the Industrial Revolution.  The exponential growth in the power and production volumes of transistors (see previous blog post)—a phenomenon codified as “Moore’s Law”—made possible the information revolution, the internet, and smartphones.  Electric cars and their battery systems have now entered a phase of exponential growth.

There are two categories of electric vehicles (EVs).  The first is plug-in hybrid electric vehicles (PHEVs).  These cars have batteries and can be driven a limited distance (usually tens of kilometres) using electrical power only, after which a conventional piston engine engages to charge the batteries or assist in propulsion.  Well-known PHEVs include the Chevrolet Volt and the Toyota Prius Plug-in.

The second category is the battery electric vehicle (BEV).  Compared to PHEVs, BEVs have larger batteries, longer all-electric range (150 to 400 kms), and no internal combustion engines.  Well-known BEVs include the Nissan Leaf, Chevrolet Bolt, and several models from Tesla.  The term electric vehicle (EV) encompasses both PHEVs and BEVs.

The graph above is reproduced from a very recent report from the International Energy Agency (IEA) entitled Global EV Outlook 2017.  It shows that the total number of electric vehicles in the world is increasing exponentially—doubling and redoubling every year or two.  In 2012, there we nearly a quarter-million EVs on streets and roads worldwide.  A year or two later, there were half-a-million.  By 2015 the number had surpassed one million.  And it is now well over two million.  Annual production of EVs is similarly increasing exponentially.  This kind of exponential growth promises to transform the global vehicle fleet.

But if it was just vehicle numbers and production volumes that were increasing exponentially this trend would not be very interesting or, in the end, very powerful.  More important, quantitative measures of EV technology and capacity are doubling and redoubling.  This second graph, below, taken from the same IEA report, shows the dramatic decrease in the cost of a unit of battery storage (the downward trending line) and the dramatic increase in the energy storage density of EV batteries (upward trending line).  If we compare 2016 to 2009, we find that today an EV battery of a given capacity costs one-third as much and is potentially one-quarter the size.  Stated another way, for about the same money, and packaged into about the same space, a current battery can drive an electric car three or four times as far.

Graph of electric vehicle battery cost and power density 2009 to 2016

Looking to the future, GM, Tesla, and the US Department of Energy all project that battery costs will decrease by half in the coming five years.  Though these energy density increases and cost decreases will undoubtedly plateau in coming decades, improvements underway now are rapidly moving EVs from the periphery to the mainstream.  EVs may soon eclipse internal-combustion-engine cars in all measures: emissions, purchase affordability, operating costs, performance, comfort, and even sales.
