# McKibben TED Talk: Our Last, Best Chance

{{< youtube 9LTGzEzDat0 >}}


Solar isn't the backup plan anymore. It's the cheap option.

## Solar Didn't Get Invented. It Got Cheap.

We used to call it "_alternative energy._" That word did a lot of quiet damage — it filed solar and wind under nice-if-you-can-afford-it, right next to organic groceries and bamboo toothbrushes. McKibben's point is that the word never got updated after reality moved. Ninety percent of new electricity built worldwide last year was solar or wind, because it's now cheaper to point glass at the sun than to burn coal. Not greener. Cheaper.

Some of the proof is almost funny, except one bit isn't actually news to me. McKibben points to Australians about to get three free hours of electricity a day as evidence of how abundant solar's gotten. Fair; except I've had [two free hours of EV charging on Powershop's plan](/posts/ev-charging-in-australian-public-networks-vs-home-charging/) for a few years now. The three-hour version isn't a new phenomenon, it's the rest of the market catching up to a deal some of us already had. 

California runs on over 100% renewables most days and just banks the extra in batteries for after dark. And in Pakistan, farmers who couldn't afford steel racks just lay Chinese panels flat on the ground and wire them up themselves, YouTube tutorial style; diesel use down 30% in two years, no subsidy program in sight.

That last one is the tell. This isn't a story about rich countries feeling virtuous. It's cheap hardware winning on price where nobody has money to waste on principle.

I went in expecting the usual TED-talk climate math — degrees, deadlines, guilt. McKibben does the math (every tenth of a degree of warming pushes about 100 million people out of a safe climate zone), but the more interesting argument is geopolitical. Oil and gas sit in a handful of places, which is why we fight wars over them. Sunlight doesn't sit anywhere in particular. Ninety-three million miles, same distance to everywhere, and none of it runs through the Strait of Hormuz.

The part that'll annoy people: solar isn't losing because it's expensive. It's losing time because it's being deliberately slowed down. McKibben names it — Trump killed offshore wind and solar permits, the Energy Secretary is on record saying there's no transition happening, subsidies went to coal instead. And still, even in Texas, most new power built last year was sun and wind. The obstruction isn't winning the argument. It's just costing years we don't have.

(_I'll admit I assumed this was going to be another if-only-politicians-got-out-of-the-way talk. It mostly is. But the fix he proposes is boring in a good way — not a moonshot, just permitting. Americans pay three times what Australians pay for solar, mostly paperwork. Utah legalized small plug-in balcony solar last year. Maine and Virginia followed last week._)

McKibben closes on Stonehenge and seasonal depression, which is a bigger swing than the talk needed. But the line under it holds up: we've been burning things since fire, and burning things has finally gotten too expensive to keep doing. The alternative isn't a sacrifice anymore. It's just cheaper.

Solar didn't get invented this decade. It got cheap. That's the whole talk.
