The Sierra Club Vision for Texas Energy

 

Matthew Johnson is the deputy director of the Lone Star Chapter of the Sierra Club.  Last week on Valentine's Day, the Austin American-Statesman published in its opinion section Mr. Johnson's thoughts about the state of the Texas energy situation.  If his piece was a valentine to the state's energy interests, it was one that had a lot more thorns than roses.

 

As the disastrous power-grid failure during the February 2021 freeze demonstrated, all was not well with the Texas energy infrastructure, and Mr. Johnson notes that in 2023, Texas voters approved spending $5 billion on grid improvements.  But in his view, the trusting voters of Texas, who simply wanted more reliable electricity at lower costs, were betrayed by "greedy industrial corporations," who directed the money into "risky, polluting, and unnecessary gas-fired power plants."  According to Mr. Johnson, this was a betrayal of public trust.  Instead, during the current session the legislature is once more considering funding both fossil-fuel and nuclear plants.  Mr. Johnson thinks nuclear plants are a bad idea, because they have suffered delays and severe cost overruns in the past.

 

What should have been done, and what he hopes the legislature will do instead, is to put our money into energy-efficiency measures and renewable energy such as more wind and solar power.  He favors a regulation that would require electric utilities, "while they don't generate electricity," to "produce energy efficiency savings that offset 1% of the energy they sell."  And he mentions practical consumer measures such as improved insulation, smart thermostats, and retrofitted water heaters.  He concludes with this rhetorical flourish: "Together we have the power to forge a sustainable path forward that benefits all Texans—not just a select few."

 

I agree with Mr. Johnson on some of his points.  Energy conservation is a good thing.  In fact, without any special regulatory incentives such as the one he promotes, the energy consumption per capita in Texas actually went down by more than 6% from 2019 to 2022.  This is part of a long-term national trend that results from a number of factors, including more efficient industrial processes, the changing nature of energy-intensive industries, and replacement of old housing units by newer and better-insulated ones.  Unfortunately for Mr. Johnson's hopes that even more energy savings will occur, the fastest way to make people and corporations save energy is to make it cost more.  And that directly conflicts with one of Mr. Johnson's other hopes:  that energy would cost less.

 

If Mr. Johnson wants our Texas grid to be more reliable, let's consider the one thing that those desperate power dispatchers wished they had on that cold February night in 2021:  rapidly dispatchable emergency generators, robustly insulated for cold weather.  The type of generator that starts up the fastest—in a matter of minutes—is exactly the kind that Mr. Johnson deplores:  gas-fired turbine plants.  Why Mr. Johnson calls them "risky," I'm not sure.  While any process involving flammable gas can go awry, I'm not aware of any special hazards associated with them.  The only significant pollution they produce is carbon dioxide, but they make less CO₂ per kilowatt than coal or oil-fired plants. In fact, a big reason that CO₂ emissions are not higher than they are is the replacement of coal and oil by natural gas. 

 

Reading between the lines, I think Mr. Johnson's vision for our energy future would be as close to a 100% renewable grid as we can get, and the shuttering of all fossil-fuel plants, and no new nuclear plants.  If we could wave a magic wand and turn his vision into reality today, I would currently be typing in the dark until my laptop battery ran down.  It is nighttime in Texas, and the wind is not blowing much, at least in San Marcos.  While for brief moments, the abundant wind generation capacity of Texas has supplied a third or more of total Texas electricity consumption, the average is much less, and the same is true of solar power.  An all-renewable grid would require storage of power that could keep us running for days with little or no wind and long, cold nights. 

 

A surprising amount of battery-based energy storage has already been connected to the Texas grid.  As of 2024, there was almost 10 GW of storage available.  That's nice, until you realize that Texas' electricity consumption has peaked historically in the range of 80 GW.  And those batteries could supply 10 GW for only a short time—a few hours, perhaps.  So even if we had enough renewables to theoretically supply all our needs, we would need about an equal amount of battery storage to keep us going, at an expense that would lead to a lot of energy conservation, no doubt—but there goes Mr. Johnson's hopes of low electric bills again. 

 

And that's the fault of those "greedy industrial corporations," no doubt.  But by its nature, a modern energy grid is a large-scale industrial project, and the best institution we have found so far for organizing and developing such things is the corporation.  As for "greedy," I doubt that energy companies, or solar-power and wind-turbine companies, for that matter, are any greedier than other industrial sectors.  They have to make a profit of some kind to stay in business.  And while I'm sure that the details of how the Texas legislature interacts with energy companies might not bear public scrutiny too well, in my view spending $5 billion on gas-fired turbine generators was about the best way it could be spent.

 

By the way, some electric utilities do generate their own electricity, contrary to what Mr. Johnson says.  Some buy power from companies that only generate, some both generate and sell, and about the only part of the grid that nobody wants is the most essential one:  the transmission lines themselves.  But even that problem is being addressed with so-called "smart grid" developments, which promise to deliver some of the energy conservation that Mr. Johnson wants.

 

Opinion pages are for expressing opinions, and we are all now more enlightened than we were concerning the opinion of a Sierra Club spokesperson about the Texas energy grid.  All I can say is, I'm glad Mr. Johnson isn't in charge of it.

India's Energy Future and Climate Change

In an article that appeared in May's Scientific American, Council on Foreign Relations Fellow Varun Sivaram shows that India's path of energy development could have a large impact on future greenhouse-gas emissions.  Unlike China, which currently pumps out about twice as much carbon into the air as the U. S., India's infrastructure is largely yet to be built.  And in that fact lies both a challenge and an opportunity.

It will help to get things in proportion if we compare greenhouse emissions and populations for China, the U. S., and India.  According to the U. S. Environmental Protection Agency, in 2014 the world leader of global carbon dioxide emissions was China, contributing about 30% of the total.  Next in line was the U. S., with 15%, and third was India, with 7%.  The much-ballyhooed Paris accords of 2015 committed India to an apparently almost meaningless limit, because Sivaram says "its overall commitment to curb emissions was underwhelming.  If the government just sat on its hands, emissions would rise rapidly yet stay within the sky-high limits the country set for itself in Paris."

By many measures, most citizens of India are still living in the same energy environment their ancestors occupied:  using dried cow dung, straw, charcoal, and firewood for domestic heating and cooking.  The lucky third or so who have access to more advanced fuel sources use either coal or oil.  The nation's electric grid is somewhat of a joke by Western standards, reaching less than a fourth of the population.  And those who get electricity can't count on it:  outages (both planned and accidental) are common, and government-inspired policies to keep rates low has resulted in chronic underinvestment that has further contributed to the grid's rickety status.

Unlike China, India has something approaching a democratic government, although with a heavy dose of socialist-style traditions left over from the Nehru years of the 1950s and 60s.  While the economy has improved greatly under more recent governments since the 1990s that have favored private enterprise and privatization of formerly government-owned enterprises, Sivaram points out that investment money is hard to come by.

Examining the two extremes of how things go from here, suppose that India follows the easier path trod already by China, exploiting readily-accessible fossil fuels and building coal-fired power plants to supply its increasing population of about 1.4 billion, which is due to outstrip China's population in a few years.  If that happens, the U. S. will no longer be the world's No. 2 carbon-dioxide emitter—India will be, and might even surpass China to become No. 1. 

Of course, this is a competition that no government wants to win.  But zooming down to the micro view of individual citizens, the meaning of drastic global-warming restrictions on future fossil-fuel use becomes more problematic.  Most Indian citizens do not drive cars, and the vast majority of motorized vehicles sold even today are motorbikes or three-wheel jitneys.  Mobility is something everyone wants, and as more Indians get better jobs and are able to save money to buy larger items, the market for automobiles could grow tremendously.  But that development would only exacerbate carbon-dioxide emissions.  The same people who want to drive would like to have plentiful, reliable electricity both for domestic uses and for things like agriculture and manufacturing.  But if power is generated with coal or oil, there goes more CO2.

In his article, Sivaram holds out an alternative energy future that could become reality, given enough willingness on the part of national and state governments and citizens generally.  Solar energy is abundant in the countryside, and the government is already deploying solar panels to power irrigation pumps, but on a small scale.  Given enough investment, the desperately-needed expansion of the electric grid could include the latest smart-grid technologies that would enable it to take advantage of wind and solar power, which otherwise would not fit easily into an old-fashioned grid designed for 24-hour-a day power sources.  And the nice thing is that little retrofitting will be required, because most of the needed grid does not yet exist today.

While coal and oil will be a large part of India's energy mix in the near future, another hope Sivaram has is that conservation measures will limit the increase in demand to less than it would be otherwise.  Rapid deployment of electric vehicles powered by renewable energy sources could help here, as well as an emphasis on energy-efficient appliances and buildings. 

The fly in this sweet-smelling ointment of the future, Sivaram admits, is the crying need for investment money.  And here is where things get murky.  In common with many other countries in Asia, India's regulatory environment is marred by complexity, delays, and corruption.  Even major infrastructure projects such as hydroelectric dams and grid improvements have been torpedoed by high interest rates, permit delays, and poor fiscal planning, resulting in abandoned projects and even bankruptcies.  These are not engineering problems.  These are social and government-policy problems, and it will take political courage and intelligence to make much progress in these areas.

With India halfway around the world, it's easy to ignore internal problems like these, but this academic semester just ending, I taught a graduate class for the first time in many years, and most of the students in it were from the Indian subcontinent.  Thirty years ago, most of them would have been from China, but there are plenty of Chinese universities that are as good or better than your average state school in the U. S. now, and so the new-graduate-student pool for middle-ranked U. S. universities has shifted south over the years.

If these students are like most foreign grad students, many of them will try to stay in the U. S.  But some will return to their native lands.  I hope that what they learn here about the social and political structure of the U. S. will help them realize that in many ways, India has a chance to avoid mistakes others have made before them.  Whatever your views on global warming, I think we can agree that it's a hard problem both to allow millions of people in India to enjoy some of the benefits of advanced technology that we in the U. S. have enjoyed for three generations, while avoiding preventable harm to the planet we all live on.  I hope the citizens of India can take advantage of their opportunities to work out this problem in the best way possible.
