The world's climate goes down the drain and nobody is doing anything against it?

Well... not quite. There is more to be done, that's for sure, every °C counts. But there has been quite some progress in the last years, and Simon Clark was so nice to make a video about it.

ENG: scroll down to The New Yorker article on renewable energies reshaping the world, whether autocrats like it or not.

ESP: "El año pasado, el noventa y seis por ciento de la demanda mundial de nueva electricidad se cubrió con energías renovables, y en Estados Unidos el noventa y tres por ciento de la nueva capacidad de generación procedió de la energía solar, eólica y de una variedad cada vez mayor de baterías para almacenar esa energía.

En marzo, por primera vez, los combustibles fósiles generaron menos de la mitad de la electricidad en Estados Unidos. En California, en un momento dado, el 25 de mayo, las energías renovables produjeron la cifra récord del ciento cincuenta y ocho por ciento de la demanda eléctrica del estado. A lo largo de todo el día, produjeron el ochenta y dos por ciento de la electricidad de California, que esta primavera superó a Japón y se convirtió en la cuarta economía del mundo. (... muchos más ejemplos en el artículo )

Esto sugiere que existe la posibilidad de una profunda reordenación de los sistemas de poder de la tierra, en todos los sentidos de la palabra "poder", ofreciendo un freno plausible no sólo a la crisis climática sino también a la autocracia. En lugar de depender de depósitos dispersos de combustibles fósiles -cuyo control ha definido en gran medida la geopolítica durante más de un siglo-, estamos avanzando rápidamente hacia una dependencia de fuentes de suministro difusas pero ubicuas."

Interesante, no solo lo dicho, sino que sea El New Yorker quien lo diga...

Sodium ion tech is a game changer. You can completely fill them and drain them without damaging them, so their practical capacity is higher than lithium ion, for the same theoretical capacity. Plus they're a fraction of the price, so you can buy much more capacity for the same price, or buy more panels with that surplus.

As a bonus, no risk of catching fire, and in theory we could make them in Aotearoa from local materials.

Thinking about the threads I posted about energy the other day. I knew that electric engines were far more efficient than even the latest combustion engines. But until I read Thorn's article on rewired.nz, I'd never joined the dots that this means we don't need the same number of calories of renewable energy to replace fossil fuel energy.

Most of the energy used in commercial flights is just to get the plane up to cruising height. What if an electric drone could help lift an electric passenger planes to cruising height, then detach and return to the airport to recharge.

The plane itself would only need to carry enough energy to maintain cruising height until it's time to land. Plus redundancy in case of delays. But it would still need to carry way less energy than existing planes.

"So, if we want to transition away from fossil fuels to renewable energy, it's going to require our manufacturing an enormous number of PV panels and wind turbines. We're going to have to make that transition something like 10 times the current rate at which we're introducing renewable energy infrastructure."

"Using some mapping we found that the rooftops of 14 of Auckland's largest buildings would have the same land area as the largest solar farm under construction [in Aotearoa]. So we could potentially be distributing those solar panels in our city ..."

Humanity needs to stop wasting public money on nuclear investment, and invest it in renewables. Especially decarbonizing proven renewable tech. Figuring out how to build and maintain renewable generation without energy and byproducts (plastics, etc) from fossil fuels is an important area of experimentation in itself.

"Scientists have used solar power to heat an object to 1,800 degrees Fahrenheit (1,000 degrees Celsius) — hot enough to power a steel furnace. The proof-of-concept study, published May 15 in the journal Device, demonstrates how solar energy could replace fossil fuels in high-temperature manufacturing processes, such as smelting steel."
