what to do about the U.S. electric grid

Leave a reply

Actually, it’s pretty simple. To deal with climate change, we need to electrify everything, bring lots and lots of renewable energy sources online, and have a grid that can handle them. Renewables are intermittent and unreliable locally, the cynics tell us, but in a big country they are always online somewhere. Our 50-year-old duct-taped together grid isn’t up to the task of getting enough electricity from where it is generated to where it is needed. Permitting, NIMBYism, and our antiquated system of semi-sovereign states are all part of the problem. But also, we just need to throw tons of money at this. The current administration and dysfunctional legislature are maybe considering a small “downpayment” that is the most they consider politically possible. Meanwhile, Asia is running rings around us, not that it is a competition.

Blah blah blah the statistics continue to tell a clear story of U.S. decline. I’m not sure how long I can keep this up – the problem is diagnosed, solutions exist and it is time to take action.

Other countries are zipping ahead in this area. China has emerged as the world’s clear leader in high-voltage transmission, building tens of thousands of miles of these lines to connect its power plants with cities across the vast nation. But while China developed 260 gigawatts of transmission capacity between 2014 and 2021, all of North America added just seven, according to a survey conducted by Iowa State University.

MIT Technology Review

This seems slightly unfair – we had a significant head start on China I would assume, so we might not need to build as much new infrastructure as they do. But this head starter is a driver of our complacency – we have been coasting on past investments for a long time, and we are running out of gas…er, juice. (This reminds me of a Chinese friend asking me once why Americans refer to electricity as “juice”, and I didn’t and still don’t have a good answer.)

the U.S. health care system is not just below average, it is the worst

Leave a reply

This is getting tiresome. Do we need any more evidence that the U.S. has slipped below average and is now bringing up the rear in many categories among developed countries? This is the 2021 Mirror, Mirror report from The Commonwealth Fund, a non-profit generally considered to be competent and non-partisan.

The U.S. ranks last out of the 11 countries included. But the ranking understates the case, because the other countries are somewhat clustered in terms of cost and outcomes, and then the U.S. is a point far away from the cloud with much higher cost and much worse outcomes. It’s not an Anglo-American failure, because the UK, Australia, and New Zealand all do well. Canada is ranked second worst, but again it is on the lower right edge of the cloud and the U.S. is way out on its own.

I do think they picked a group of very high performing countries here. There have to be other developed countries, particularly in Asia, that could have been included. But somehow, I doubt including Japan, Taiwan, etc. would make the U.S. look any better.

I wonder though what would happen if they tried to compare just the over-65 U.S. population served by Medicare to the over-65 population in the other countries. If Medicare does much better than the U.S. health care “system” (i.e., cluster-you-know-what) as a whole, it would be an even stronger argument for Medicare for All. Should the U.S. maybe try to establish a health care system before the next pandemic arrives?

early warning of Gulf Stream collapse?

Leave a reply

There has been plenty of hypothesizing that global warming could cause destabilization of key ocean currents that have determined the character of the world’s regional climates over the last few millennia or so, i.e. human history. This new paper is the first I am aware of (but I am not even close to an expert on this subject or oceanography more generally) to find empirical evidence that the the AMOC current (which I believe includes the Gulf Stream) could be nearing a tipping point.

Observation-based early-warning signals for a collapse of the Atlantic Meridional Overturning Circulation

The Atlantic Meridional Overturning Circulation (AMOC), a major ocean current system transporting warm surface waters toward the northern Atlantic, has been suggested to exhibit two distinct modes of operation. A collapse from the currently attained strong to the weak mode would have severe impacts on the global climate system and further multi-stable Earth system components. Observations and recently suggested fingerprints of AMOC variability indicate a gradual weakening during the last decades, but estimates of the critical transition point remain uncertain. Here, a robust and general early-warning indicator for forthcoming critical transitions is introduced. Significant early-warning signals are found in eight independent AMOC indices, based on observational sea-surface temperature and salinity data from across the Atlantic Ocean basin. These results reveal spatially consistent empirical evidence that, in the course of the last century, the AMOC may have evolved from relatively stable conditions to a point close to a critical transition.

Nature Climate Change

This would seem to have major consequences to (1) where and how much food we can grow in the world, and (2) the location of our actual physical coastlines and the coastal cities that house much of the world’s human population. Adjusting to gradual long-term changes in these things will be a challenge. A sudden, major shift might be something our civilization can’t adjust to. The consequences are unimaginably dire. The risk is unknown but this study suggests it is real. Logic and risk management principles suggest that we need to be cautious here and actually do what we can to avoid this. Let’s hope “a point close to a critical transition” is not really all that close in human terms, and we have time for our civilization, with its flawed geopolitical and economic systems, to come to its senses.

mushrooms in space

Leave a reply

I learned a few things from this Scientific American article. First, fungi can be very useful in space because they break down hydrocarbons, which are abundant but not hospitable to life, and turn them into sugars, which are not abundant in space and do support life. Second, they create hard carbonaceous materials which can provide protection, insulation, and even conduct electricity. Third, at least some scientists think fungi will be discovered in space. Fourth, the character Paul Stamets on Star Trek Discovery is named after a real scientist named Paul Stamets, who wrote the book Mycelium Running, which I have heard of an haven’t read. And finally, something I knew but for the record have no personal experience with to date, psychoactive mushrooms can treat depression, loneliness, and post-traumatic stress disorder, all of which are going to occur anywhere in our universe humans choose to go.

Limits to Growth Re-revisited

Leave a reply

Someone revisits Limits to Growth every now and then. This author says the world is tracking the most pessimistic scenarios examined in the original model, and that stagnation or collapse in the next decade is a real possibility. The attempt at a silver lining – there is a chance that it might not be too late to do something.

but we’re ready to fight a war, right?

Leave a reply

Yesterday I concluded the U.S. is not ready for a significant disaster. But one thing we commit plenty of resources to and are good at is fighting wars, right? In fact, we are so good nobody will even mess with us, right? Not so fast. There is buzz at the moment over a war game that supposedly showed the U.S. catastrophically losing a conflict over Taiwan. Communications were disrupted immediately by missiles, drones, and attacks on infrastructure like undersea cables, and without communications the U.S. forces couldn’t fight effectively.

I’m a little skeptical. Why would the U.S. military intentionally publicize something like this? I suppose scaring a domestic audience into committing even more resources is always one reason. A cold war with China is a good reason for our military-industrial complex to keep sucking up 5% or so of our economy, and Taiwan is the most obvious flashpoint that could go from cold to hot. If brinksmanship or bluffing to sustain military funding is the game here, the risks are too great to play the game. Seriously, let’s not let this happen.

U.S. not prepared for megadisasters

Leave a reply

The description for this 2006 book Americans at Risk: Why We Are Not Prepared for Megadisasters and What We Can Do is eerily prophetic. Then again, I can’t rule out the possibility that it was updated in the last year or so to appear eerily prophetic in hindsight.

Five years after 9/11 and one year after Hurricane Katrina, it is painfully clear that the government’s emergency response capacity is plagued by incompetence and a paralyzing bureaucracy. Irwin Redlener, who founded and directs the National Center for Disaster Preparedness, brings his years of experience with disasters and health care crises, national and international, to an incisive analysis of why our health care system, our infrastructure, and our overall approach to disaster readiness have left the nation vulnerable, virtually unable to respond effectively to catastrophic events…

As a doctor, Redlener is especially concerned about America’s increasingly dysfunctional and expensive health care system, incapable of handling a large-scale public health emergency, such as pandemic flu or widespread bioterrorism. And he also looks at the serious problem of a disengaged, uninformed citizenry—one of the most important obstacles to assuring optimal readiness for any major crisis.

I thought we responded okay to 9/11 in terms of the actual local area where it happened. Obviously we didn’t prevent it or prepare for it, and starting two wars with countries that were mostly uninvolved can’t really be considered a response at all. Katrina is another story. When I look back, that failure on a regional scale was a harbinger of our coronavirus failure on a national scale. And coronavirus, awful as it has been, is marginal in terms of what a megadisaster could really unleash – think a disease that kills 99% instead or 1% of people infected, even a limited nuclear war, an earthquake or volcano large enough to devastate an entire densely populated region, sudden ice sheet collapse, or a catastrophic collapse of the food and/or energy systems.

It seems to me that surviving the medium-term future as a nation and civilization requires us to address both the slow and steady long-term trends like global warming, and to be prepared for the sudden catastrophic events we are going to have to deal with. The two are clearly related – dealing with the long term trends can lessen the frequency and severity of some of the short-term events, but not eliminate them.

the Nordic welfare model

Leave a reply

This article explains that the Nordic welfare model succeeds by targeting the middle class, not just the poor. They provide services of high enough quality (child care, health care, education, unemployment, disability, retirement) that the private sector can’t compete. Then the middle class voters support the politicians who support the policies, and are willing to pay the taxes necessary to receive the benefits.

Seems simple, but it’s easy for anti-tax corporate and wealthy interests in the United States to prevent this feedback loop from getting established. They just spew propaganda and buy off politicians who are anti-tax and anti-deficit spending, so the government only has resources for limited programs targeting the poor, the middle class resents paying taxes and receiving little in return while having to pay for sub-par private benefits at the same time, and they continue to vote against policies to expand benefits. Breaking this loop would require a gamble on massive deficit spending (kinda sorta being tried now, legitimately during a crisis in my view) and/or constitutional changes/reinterpretation that stop the legalized propaganda and bribery (which would have to be enacted by the politicians who are being bribed, unless judges were to take the lead which seems unlikely).

Tesla on the water

Leave a reply

Some (all?) Tesla 3’s, apparently, are designed to effectively navigate flood waters in a sort of boat mode. Don’t try this at home, i.e. on the road near your home. First of all, you don’t know if your Tesla 3 has this feature. Second of all, even if you know you have this feature, you might take more risk, enter flood waters you wouldn’t otherwise enter, and end up equally dead.
