The Capitalism Strain

 


Researchers with the Massachusetts Institute of Technology (MIT) and the Pontifical Catholic University of Chile have developed an insulating material which allows a device to achieve a cooling differential of up to 23 degrees Fahrenheit using no electricity and no moving parts. 23 degrees cooling may not be sufficient on its own in all applications, but it will certainly increase the efficiency of existing devices by assisting them in not working as hard and thereby using less electricity. The useful attributes of the new insulator will help mitigate the climate warming effects of increased use of air conditioning and refrigeration, which in turn can lead to increased climate warming, and on and on.

 


Heating and cooling of indoor spaces accounts for between 40 and 60 percent of energy use worldwide, depending on location and also on who is doing the studies and how. It’s enough to know that indoor climate control is the single biggest factor in energy use around the world. Heating is the larger portion of the 40 to 60 percent of energy use, but that could flip by mid-century as the warming climate increases demand for cooling and lessens demand for heating. Be that as it may, it helps to understand that overall energy use will continue climbing, as it has throughout human history, though perhaps at a lesser rate due to improvements in the efficiency of devices and systems.

The achievements of researchers and engineers who develop improvements in using energy more efficiently are necessary and helpful in the fight against global warming, and they are to be lauded. It is government and business leaders and ourselves, the users of energy, who deserve condemnation as improvements in energy efficiency come without changes in the overall demand for energy and reduction of its deleterious effects on the climate. Embracing improvements in efficiency without simultaneously reducing our demand for more of a currently harmful thing is like rearranging the deck chairs on the Titanic.

Eliminating the burning of fossil fuels for energy will make the single greatest reduction in the pollutants causing global warming. That seems obvious, and it’s a simple statement to make, but it conflicts with powerful corporate, capitalist interests. Switching energy production entirely to renewable sources like wind, solar, and hydroelectric will greatly reduce pollutants, though not eliminate them. That also seems obvious. Ignoring for the moment the fraction of the population who blindly refuse to acknowledge responsibility for what is happening all around them, there is a greater obstructive force standing in the way of reducing carbon emissions enough in the next 10 years to slow – or even halt – climate change, and it is called capitalism.

The Trio of Emmylou Harris, Dolly Parton, and Linda Ronstadt sing “After the Gold Rush” on Late Show with David Letterman on March 24, 1999. Neil Young wrote the song for his 1970 solo album, and the lyrics of the final verse dreaming about escape from this planet to a new home are bound to remain a dream for the foreseeable future, despite the efforts of technology capitalist Elon Musk.

At the climax of Michael Crichton’s 1969 novel The Andromeda Strain, the team of scientists studying an alien microbe they have dubbed “Andromeda” discover in the nick of time that the destructive microbe would grow out of control if given a nearly limitless source of energy, in this case the detonation of a nuclear device meant to contain it by destroying it. They discover the opposite would happen, that the Andromeda strain would feed greedily on the energy supplied by nuclear fission and would quickly overtake the planet, and in a tense scene during the countdown to detonation, they manage to disarm the research facility’s nuclear device. Capitalism is similarly greedy and destructive. It is a system that needs close watching and regulation, not the rampant deregulation of the past 40 years. Like the unregulated sex urge which has led to global overpopulation and the consequent strain on the earth’s resources, greed is also an innate urge in humans, an urge that has found its closest reflection in capitalism, and unregulated it plunders and eventually destroys the earth’s resources, including its many peoples, rich and poor alike.

The Conspiracy Line

 

By the 1960s, of the hundreds of streetcar lines that had once been a primary mode of transportation in cities and suburbs across the United States in the first half of the 20th century, only a small fraction still operated, and usually only in city centers. Competition from automobiles and buses was one cause for declining ridership of streetcars, and supposedly the costs of installing and maintaining lines was higher than costs associated with infrastructure for cars and buses. The history of what happened in the major mid-century makeover of American urban mass transit is muddled, and one explanation for it that keeps popping up has to do with the machinations of the automobile manufacturers, chiefly General Motors (GM).

 

The idea springs from how GM bought out streetcar lines around the country, and then dismantled the lines, junked the streetcars, and signed city governments to contracts for purchase and ongoing use of the buses GM manufactured. GM also sold cars to urban and suburban commuters who found themselves with fewer alternatives than they had before the 1920s, when the streetcar lines were still thriving. That’s a neat story, and it certainly fits in with the behavior we have come to expect of large corporations and the executives who run them, but in this case it turns out to be a little too neat and only partially true.

Market forces generated by consumer preferences played the greatest part in the decline of ridership on streetcar lines starting in the 1920s and accelerating through the next quarter century. The streetcar lines were privately owned and the companies bore the costs of maintaining the tracks they operated on and other infrastructure costs, even though they used the same publicly maintained roads as buses and cars. The streetcar lines were more and more at a competitive disadvantage as public money benefited those other modes of transportation and as consumers came to prefer the relative freedom of driving their own cars or taking buses that weren’t restricted to tracks.

Comforting as it might be to blame the automobile and gasoline industries for ripping up streetcar tracks around the nation, depriving commuters of a useful commuting option, the truth in this case is that the public shoulders the greater responsibility. Individual consumers operating in their own self-interest took advantage of cheap gasoline and publicly financed road building, such as the interstate highway system started in the 1950s, to buy at least one car for every household. In most cities, taxpayers balked at public ownership of the streetcar lines, a move which would have saved many of the lines from the corporate scavenging that ultimately killed them off. In other words, GM and other auto and gas corporate interests didn’t precipitate the demise of the streetcar lines, but neither did they mourn their loss, and ultimately, of course, GM and the others profited greatly from the makeover of the American transportation system.

By the time of the 1959 release of Alfred Hitchcock’s North by Northwest, the streets of Manhattan were dominated by vehicular traffic, and mass transit options for New Yorkers were limited to subways and buses. Bernard Herrmann composed the music for the film, and Saul Bass designed the titles. The director makes his cameo appearance at the end of the title sequence.

More than a half century after streetcars were all but wiped off the map in America, they are coming back in spots like Brooklyn, driven by the desire of some people to get around town without the hassles of car ownership, the pollution of cars and buses, the blight of enormous parking lots, and the swallowing up of green spaces for more roads to alleviate the congestion on existing roads, only to have the new roads fill up as well. Streetcars powered by electricity generate pollution at a remove, to be sure, but as more power plants use renewable energy sources, that problem should lessen. Meanwhile, building out more mass transit infrastructure should take off the road some of the oversized vehicles too many Americans appear to love, and which the automobile makers and the fossil fuel industry love turning out for them since they are highly profitable. It has taken a century for Americans to learn anew the value of mass transit options like streetcars, and perhaps soon, before we reach the end of the line, gridlock on the roads will clear, and so will the air everywhere.

Saving Up for a Rainy Day

 

Battery storage has long presented a conundrum to renewable energy enthusiasts who tout the relatively benign environmental footprints of wind and solar power. The batteries can contain toxic metals and chemicals which cause environmental damage in mining and formulation, and then again when they have exhausted their usefulness and users need to somehow safely recycle or dispose of them.

For a time, it seemed the answer for homeowners using a solar array was to sell excess power produced during the day to the power company and then draw on grid power at night and on cloudy days. These grid-tied systems effectively used the power company as storage, mostly dispensing with the need for a bank of batteries at home. Unfortunately for homeowners with grid-tied systems, it appears power companies are backing away from those setups in order to protect their equipment and to maintain tighter control over power generation.

Power companies have been investing in their own renewable energy production as costs go down. Since there is no external backup for the electricity generated by the power company, the power companies need to employ huge amounts of batteries. Batteries have improved in the past generation both in toxicity and length of usable life from the days of lead acid batteries. Improvement does not mean they are exactly environmentally friendly. The problem comes down to relative harm, such as whether it is less harmful to the environment to drive an electric car when the source for its electricity is a coal burning power plant.

An illustration of the relationship of renewable energy to energy storage from the German cartoonist Gerhard Mester (1956-). Panel 1: “More solar energy!!” Panel 2: “More wind energy!” And in the last panel: “More energy storage!” Incidentally, Germany is a world leader in solar energy production despite receiving less sunlight than many other industrialized nations.

Nothing people do technologically has zero impact on the environment, and arguments from the extremes of both sides of the tug of war between those in favor of continued use of fossil fuels and those who want greater reliance on renewable energy are neither accurate nor helpful. Continuing the status quo of burning fossil fuels for most energy production is clearly a path to environmental catastrophe, while renewable energy production does not have quite as low an impact on the environment as some enthusiasts suggest. It is in the batteries especially that renewable energy has an unfavorable impact.

Nevertheless, in countries with higher renewable energy production than the global average the air is cleaner and greenhouse gas emissions are lower. Because the sun doesn’t always shine and the wind doesn’t always blow, the key to minimizing reliance on batteries, the most toxic element in renewable energy use, is diversification of power sources supplying the grid, from geothermal to hydroelectric. None of these methods of supplying the power necessary for humanity’s modern lifestyle are perfect, but they are all better than the alternative of continuing down the path of polluting the air and warming the planet. The two biggest obstacles to switching the United States to 100 percent renewable energy are the fossil fuel industry interests entrenched in national politics, and battery technology. Of the two, the latter will be more easily overcome by a concerted effort, and with time the new technology will push out the former technology and its moneyed adherents as obsolete and destructive. But will it be soon enough?
