Previous similar drops in emissions were due to periods of economic stagnation or recession--this is the first significant drop in emissions that has coincided with GDP growth.
The majority of this decline is due to changes in energy use and generation. Coal demand has dropped nearly to 1900s levels, while use of renewables grows significantly--for the first time renewables accounted for half of the energy generated in "advanced economies" included in this analysis.

In the first three months of this year a third of the country's electricity came from wind farms, research from Imperial College London has shown.
National Grid has also confirmed that April saw a record period of solar energy generation.
By 2035 the UK aims for all of its electricity to have net zero emissions.
"There are still many hurdles to reaching a completely fossil fuel-free grid, but wind out-supplying gas for the first time is a genuine milestone event," said Iain Staffell, energy researcher at Imperial College and lead author of the report.

Did you know Texas produces over 25% of the wind-powered electricity in the US, despite the largest wind farm being in California's Tehachapi Pass?

Solarpunk in the Desert
Tumblr media
Let me talk a bit more about Solarpunk this week. Especially about Solarpunk in different climates and areas. Because, let's face it: Most of Solarpunk art does depict either (sub)tropical foresty areas or at least temperate regions. It does not show any other climate extremes, which is kinda sad, because the world does not only exist in those lush green areas.
Of course, one of the big reasons is, that it kinda depicts the places it is from. For once South America had a big influence on Solarpunk, which is most oftenly associated with the lush rain forest of the amazonas. But also... White people kinda feel most at home in temperate regions.
But if either we woud establish a Solarpunk world - or you just wanted to write a Solarpunk stories... There would still be deserts.
And sure, we could talk about stopping desertification and such things. Something that is definitely important. But some desert should remain, because they are still a unique habitat. So, what does Solarpunk do with that - and how could people live in those areas?
Now, I have to underline again: Deserts are habitats for all sorts of flora and fauna. Animals live their, no matter how inhospitable to life they seem to be. Because of that they should be protected to some degree. Again: We should stop the spread of deserts into other habitats, but the desert in of itself is home to a lot of life, even if it might not seem that way.
As such it has also been a habitat to humans for a long while. No wonder. While humans did not originate in the deserts of Africa, those were darn close and of course some of the first humans went there and some managed to survive there. As such our species has actually a lot of experience when it comes to surviving in the desert.
Humans for the most part will not live in the middle of the desert, of course, but rather at the outskirts or maybe at an oasis of some sort. But of course even there people might need to deal with the elements. Like the heat, the sun, the cold nights (never forget: deserts are very cold at night), the generally dry climate.
Of course we could deal with the heat with ACs, but... ACs are not very good for the environment of course. But also: For most of human history, humans did not have ACs and humans have actually found a lot of ways to keep houses relatively cool through passive cooling system and by using building materials, that cool the insides and help the place well tempered.
But of course in modern times, we also could use heat pumps to move the temperate air around and keep the houses cool during the day and warm at night.
One big issue is the water. Of course, humans tend to go to places where there is water. Like an oasis or close to a lake or other body of water. But of course we do have an issue with the ground water declining for several reasons. So, what can we do?
Well, actually we have found intesting ways with harvesting the water from the air through all sorts of methods. For example by spanning wires, where the daw can collected during thr night. While it is not plentiful, it does work quite well.
But, of course, I cannot talk about solarpunk deserts without talking about photo voltaic and also wind energy.
There are those folks, who will propagade that it would be super practical to build like this giant, giant photo voltaic farm in the middle of the Sahara and then get all the energy from it. Which, technically... I mean, a lot would have to change, but yeah, there is a lot of energy there.
Even though... I am not a big fan of this idea. Because, again: Habitat. And animals cannot all live in those areas, where there is big, big photovoltaic. Still, some areas of the desert could be used as such to add to the general energy grids.
And, yes. There is also wind energy. Something a lot of people do not consider. But a lot of deserts have very windy areas, which could easily be used to generate energy. So... Yeah, that would be nice, wouldn't it?

I went to Camila to get two different Solarpunk pieces done! I thought to myself “we don’t really have much Solarpunk art of different biomes. I want to find someone who could help change that.” So I found Camila! The first art piece is supposed to be in North America, near where Canada and Alaska would be. It has mostly wind energy as the dark night can be months at a time, so there could be hardly any sun for solar panels. The second one is in a mountainous region in Asia. Since it’s so high up they can get good winds up there so they also use quite a bit of wind power.
Anyways, here’s Camila’s website if you want to go get a commission! https://camilasc.com/

“Experts are calling time on the fossil age as new analysis shows wind and solar power produced a record amount of the world’s electricity last year.The renewables generated 12 per cent of global electricity in 2022, up from 10 per cent the previous year, according to the report from clean energy think tank Ember.And while a small increase in coal burning pushed electricity emissions up to an all-time high, analysts predict this will be the peak of pollution.”

Well over a century after the Age of Sail gave way to coal- and oil-burning ships, climate change concerns are prompting a new look at an old technology that could once again harness wind to propel commercial cargo ships — this time with the goal of reducing greenhouse gas emissions. Imagine what looks like Boeing 747 wings with movable flaps, set vertically on a ship's deck. The vessel cruises under minimum power from its giant engine as computerized sensors adjust the fiberglass wings to take advantage of the wind's speed and direction. This wind-assisted propulsion saves a substantial amount of fuel and reduces the carbon belching from the ship's stack. Many experts think the idea has the potential to navigate the notoriously dirty shipping industry toward a greener future.
