The US is never going to take a substantial action against climate change until there's a huge change in attitude. On one side, conservatives are in denial. On the other side, liberals want companies or the government to pay for change and magically shield the cost away from the people. A carbon tax would be much more straightforward and effective than a "Green New Deal," but you don't get elected for promising to raise taxes. Instead, we get feel good programs like Cash for Clunkers and solar panel rebates that mostly just help the wealthy.

I'm curious about that too.

I think Solyndra by itself is not strong evidence of anything. Any big loan program will have big failures. The real question of efficacy is not "were there zero losers" but "were there enough winners in the portfolio to make up for the losers".

Furthermore, I think the case could be made that governments are partly responsible for solar's historic price decline. The manufacturers needed economies of scale and learning, and demand subsidized go by governments (Germany, USA, China, Spain, etc.) really helped accelerate those private sector advancements. I'm not really sure how to evaluate this narrative, but I wouldn't be surprised if there were some academic economists who have looked at it.

I think the Manhattan Project is the exclamation point of what really decided the ultimate victors of WWII:

Industrial capacity and efficiency.

What’s interesting is that German industrial capacity, despite being bombed 24/7(US daylight and British nighttime raids often in excess of 1,000 bombers) were able to continue producing warfighting equipment in increasing record numbers often with the use of slave labour.

Despite increased German industrial production of warfighting equipment despite being bombed, the US strategic industrial depth ensured ultimate victory rather than tactical prowess.

What’s interesting in Stan McChrystal’s recent book “Team of Teams” is his mention that while 20th century conventional conflicts were about industrial capacity and efficiency, the 21st century will likely be about adaptability.

What was the downside? It was part of a loan program that made money -- and while Solyndra didn't survive, it's because solar prices plummeted in a way that's good for consumers and good for the environment.
I'm not making an argument from semantics- whether or not you approve of the above explanations, they are the reason nuclear power is commonly said to be incapable of load-following. If you want a detailed and reputable investigation, the OECD has one[1].

The inability to load-follow is not a design flaw; any reactor built in the last ~40 years can ramp an order of magnitude faster than coal or gas-steam, and will run very happily at anywhere from 50-100% power, ramping up and down multiple times per day. Many can ramp at hundreds of megawatts per minutes. In fact all of them can ramp from 100%-10% output in about a minute, since that's legally required for reactor SCRAM.

That's as fast as an average gas turbine[2] and at the high end it's faster than the fastest gas turbine. Nuclear plants are the most agile nonrenewable plants on the grid but the fact is that a nuclear plant operating <80% output does not generate a return.

> Throttling the plant doesn't reduce it's profitability, since the power it would product at that point has no value - that's why you need to throttle it.

I get what you're saying, but it's wrong. The grid is not a free market and excess generation is not legal. Electricity markets are based around contracts and producing too much is just as heavily penalized as producing too little. If you generate so much excess that you bring grid frequency or voltage out of spec, people start going to jail.

To rephrase: If a nuclear plant throttles, its costs are constant and its revenue is lower. If it doesn't throttle, its costs are higher and its revenue is lower. Nuclear sees rising revenue/kWh by throttling, but not enough. Because of all that nuclear is not profitable in short term contracts. Generally they aren't used for ancillary services either, but that's more due to conventions- for instance they are used for frequency control in France.

> Everyone wants to protect the environment. But I watch out for two important costs: economic, and centralization of power...
I prefer a decentralized approach. People nearly always underestimate the rate of technological change. Solar panels, battery tech, and electric cars are a winning combination...

You do realize that these technologies you tout have all benefitted from serious, centralized subsidy and incentive programs from major economies like EU, China, and the USA, right?

Similarly oil, coal, cars, etc benefitted from those same subsidies in their turn.

Even though millions of people making local choices is the way to make macro changes, those choices are sensibly based on local, short-term criteria. If you think there's an externality not overt at the point of use, you need a large centealized solution to change it.

Even the markets for purely consumer products like, say, the VCR were unlocked by crucial central policies like refusing to kowtow to music/Hollywood in the 1970s and 80s. Mobile phones boomed in the 1990s...except in the US where the government was uninterested in making the policies that unlocked those markets. Credit card infrastructure in the US is primitive because the clearing cartels aren't interested in fixing things....while their entire business would not exit had the government not mandated certain rules on card acceptance, cash discounts, and locus liability back in the 1960s.

> Heavy handed government mandate just doesn't work due to inefficiency and bureaucratic mismanagement.

And the free market has shown that it is not capable of dealing with certain types of externalities. Consider the following example: suppose that it were guaranteed to be true that burning fossil fuels now at our current rate would cause a 5 degree C rise in temperature in 200 years. Now, of course I understand this may not be the actual case, and there is some actual amount of uncertainty, but my point is that even if it were guaranteed to be true, would free market forces cause a change in behavior? I certainly don't see how they would: there is money to be made now, while global devastation is someone else's problem.

I wish folks would get away from the "government vs free market" tribalism and come to the more rational conclusion that there are some things the free market is excellent at, but dealing with far off consequences in the face of short term gain is definitely not one of them.
Here’s another:
Black females and asian males are less likely to be in interracial marriages [1]. Under the heading “For blacks and Asians, big gender gaps in intermarriage”

Of course this only paints part of the picture, since it sliced and diced the data differently. Ideally you’d have much more comprehensive statistics about people in relationships, and the statistics wouldn’t just be % of intermarriage, but all marriages. However you should be able to extrapolate, since all marriages = interracial + interracial marriages. So if asian females have higher rates of intermarriage and males don’t, then there presumably are a surplus of unmarried asian males (and black females for that matter).

My big problem with nuclear (fission) is that while on paper it looks like a great solution, in practice our civilizational apparatus does not appear to be up to the task of long-term responsible implementation. Fission power looks like a long game of hot potato, where everyone hopes they won't be the ones on the hook when the eventual equipment failure, natural disaster, or time to decommission eventually arrives. (And, as an observer outside the industry, building a plant while taking all those into account in advance seems to be something we are either unable or unwilling to do.)
A worthwhile argument, though it would benefit from having some actual magnitude numbers for comparison.
Apropos the US body market: there's a cartel that controls who gets body parts for research; life science startups find it tough to get human tissue for physiological research as the big companies and big research institutes end up with priority access.

Few people are putting 85kwh into their car everyday. Their daily driving requires just a fraction of that, more like 10-15kwh. In the summer my solar panels generate 2-3x that amount easily.

You are correct that there's still a need for a grid. But that grid can be cleaner and more efficient with renewables and energy storage that gives everyone similar benefits to solar panels on their roof.

I agree. Technology always makes progress, so it is inevitable that clean energy will be dominant in the future. The question is whether that will be too little too late.

> gasoline cars will be worthless scrap heaps over night

This is true if the market is allowed to operate freely — “free” should not be confused with “unregulated.” Unfortunately, when it comes to energy in the US, the market is cleverly controlled to push the inevitable rise of clean energy back several decades. It has been this way for a while now. The regulation here might seem heavy handed, but that’s the kind of push that clean energy needs to win the uphill battle it’s fighting. If we hadn’t rigged the market for so long, then the natural progress of technology would have addressed climate change in time. But now we’ve waited to long, and we need hard hitting policies to peddle back the pace of the damage.

> It feels like a fight and will disrupt many lives, and it doesn’t need to be that way.

This is where you won me back over. The truth is that it is a fight. But it is important to note for those of us who want to address climate change that how we fight is important. Unlike some other markets, we haven’t really had the opportunity as a country to see what a regulated, climate-focused market looks like. So, if we push some policies that take away jobs from people who have been working in coal mines their entire lives, then that’s going to be the headline. Everyone for so long has been saying that clean energy is too radical, and it will kill the economy. We have the opportunity to implement a comprehensive plan for a gradual transition. Bring clean technology to the forefront while helping those that will suffer to slowly transition into retirement. If we can address climate change, create a new sector of jobs, and let an old market die gracefully, then the naysayers will have nothing of substance to complain about.
