This is a very poor analysis, since it doesn’t account for the capital costs. Even if hydrogen is inefficient compared to batteries, it could win if the upfront investment was low enough to offset the additional fuel cost. This is quite o

Both of the charts I posted have GDP as the denominator (although I incorrectly said the first was “share of budget”). I think it’s very important to use GDP as a denominator, because otherwise you’ll be stuck crying wolf, saying “debt alwa

I was mistaken to say “share of budget”, because the chart I linked to is actually share of GDP, which hopefully isn’t affected by the problem you pointed out.

If you compare government budget as share of GDP, you can see that is hasn’t “exploded”, outside of crisis periods. Current spending rate is elevated about 25% over the 1990s period of restraint, but quite close to the 1980s. https:/

Was the 1990s austerity “severe”? I remember a lot of complaining at the time, but it doesn’t seem too bad in hindsight.

Rather than reading this opinion piece, you can learn more about the “debt crisis” by just studying this chart which shows what percentage of the federal budget goes toward paying off the debt: https://fred.stlouisfed.org/se

The diminishing return happens when you have so many solar panels that on a sunny day you generate more than 100% of the electricity you can use. Maybe that situation is great if you want to subsidize solar panel factories, but you get les

That just means that China started later. Europe is already past 50% and are on the top half of the S-curve where adding additional renewables has diminishing returns.

It’s just a mindless comment by someone who doesn’t keep up with the latest developments. Perovskites already entered small scale commercial production last year and are being deployed in the field to validate how well they hold up in real

In the TV show Silicon Valley, there’s a joke that Nelson “Big Head” Bighetti, the perennial underperformer, did his undergrad at ASU. But I guess that’s one thing the show got wrong, because Arizona State University finished among the top

Hydrogen-ready power plants are already being built, so that’s actually the least difficult part of the problem. The current bottleneck is actually producing the hydrogen, and next will be building the transport infrastructure. https:&#x
