If it woes, it leads

We’re backing into the climate future/present with woes leading the way. It’s the perfect media framing and supports the status quo – yes everything is awful. We’ve tried nothing and we’re all out of ideas, let’s see how we can keep cheap gas going a little bit longer. It’s this way, in part, because ALL of the progress is boring. For instance, wide bandgap:

Silicon and silicon carbide are useful in electronics because they are semiconductors: They can switch between being electrical conductors, as metals are, and insulators, as most plastics are. This ability makes semiconductors the key materials in transistors — the fundamental building blocks of modern electronics.

Silicon carbide differs from silicon in that it has a wide bandgap, meaning that it requires more energy to switch between the two states. Wide bandgap, or WBG, semiconductors are advantageous in power electronics because they can move more power more efficiently.

Silicon carbide is the senior citizen of WBGs, having been under development as a transistor material for decades. In that time, engineers have started using younger upstart WBG materials, like gallium nitride, or GaN. In the 1980s, researchers used gallium nitride to create the world’s first bright blue LEDs. Blue light comprises high-energy photons; gallium nitride, with its wide bandgap, was the first semiconductor that could practically produce photons with the sufficient energy. In 2014, three scientists were awarded the Nobel Prize in Physics for that innovation, which became ubiquitous in devices like TV screens and light bulbs.

Lately, researchers have started using gallium nitride to improve power electronics. The material reached commercial fruition over the past few years in adapters for charging phones and computers. These adapters are smaller, lighter, faster-charging and more efficient than traditional ones that use silicon transistors.

“A typical charger that you buy for your computer is 90 percent efficient,” said Jim Witham, chief executive of GaN Systems, a Canadian company that supplied the transistors in Apple’s gallium-nitride laptop chargers, which were released last fall. “Gallium nitride is 98 percent efficient. You can cut power losses by four times.”

Keep going, science.

When at all costs

Quite likely, that the news of Oil’s decline will arrive long after it has actually begun to happen. That’s mostly the way most things work – just ask all the Hillbillies people Elegying worried that the demographics of the U.S. are changing!

Even so, BNP Paribas has startlingly concluded that the economics of oil “are now in relentless and irreversible decline”:

The report is good news for humanity because it means peak oil demand may be less than a decade away, which in turn means ambitious climate goals will be more affordable than previously thought.

But the bank’s analysis, “Wells, Wires and Wheels,” is devastating for Big Oil. It concludes that “the oil industry has never before in its history faced the kind of threat that renewable electricity in tandem with EVs poses to its business model.”

But one of the most startling findings is that because the cost of running EVs on solar or wind power is dropping so rapidly, the only way gasoline cars can compete with these renewable energy-powered EVs in the 2020s is if the price of oil were to drop to $11 to $12 per barrel. The current price of oil is over $50.

Even worse for oil, this economic analysis doesn’t even factor in many of the other benefits of running cars on renewable power rather than oil. These include the vast public health benefits of not breathing air pollution from burning oil, along with the benefits of not having huge oil spills and of not destroying a livable climate.

Couldn’t happen to a nicer, more thoughtful and civic-minded group. It would honestly have been much better had we just thanked them around 1967 and made the direct move to the obvious as it had already by then been long-imagined. But no. There were markets to dominate and profits to lose and wars to fund, thus the long drawn out halftime show that just embarrasses everybody with the need for enormous flags, jet flyovers and pale people in native costumes. Can’t enjoy this show and take no pleasure in their decades-late demise.


Just a note about the button there on the right. I won’t pretend not to have added it to the site if you won’t pretend you didn’t notice it.

Seriously, though, a little time line: whatdoesgreenmean.wordpress (free!) launched in April 2008; moved to whatdoesgreenmean.net (not free!) in the fall of 2008, basically in its present form. It may be time for 3.0, as I seek to keep you, and me, interested and engaged.

So, I’m considering a re-design for the site – nothing crazy, just a move to a content management system that takes advantage of the talents of the guy who does our hosting. Plus it would have a slightly different appearance. And though these elements would be good for the site, it’s not something I can contemplate underwriting myself at this point. So I thought I would solicit (your) help. Nothing more.  Whether you decide to help or not, I already appreciate your support of the site and its steady growth. 

Thanks and let me know what you think.
