For the fourth day in a row, Earth has broken or equalled its hottest average temperature record

...and decreasing the utilisation of their coal fleet to the point where their coal consumption for electricity is flat and set to start decreasing next year.

And their renewable energy share is higher than the US (and most of the world) and increasing faster.

Stop whatabouting and fix your own shit.

Coal consumption is quadruple now, and oil and gas are both on the same scale. Easy to turn those centuries into decades by increasing emissions 6-fold.

Blaming population is also inaccurate. The new people are largely not wealthy (both country by country and within each country) and contribute less to the totall emissions than a quarter of the upper 10%.

Eating meat creates four times more greenhouse gases than being vegan, landmark study finds

Reply in thread

If the entire world turned vegan would it make a difference?

...yes. Plainly and obviously. Most land use would be gone overnight. Deforestation would stop immediately as would the second largest source of methane, one of the largest sources of NO2, and billions of tonnes of CO2 per year (about a quarter of all emissions). No other single initiative other than maybe ending urban driving would come close.

If you're in the global top 50% there is absolutely nothing stopping you from switching to a primarily plant based diet, and if you're in the bottom 50% you probably don't eat enough meat to be a major impact.

Scientists invent double-sided solar panel that generates vastly more electricity

Reply in thread

Bifaciality isn't new or limited to perovskite based PV. Ground reflection is also not the only source of indirect light.

This article is very bad, but bifacial panels are starting to dominate the industry for good reason. The backside gives a 5-20% boost in total annual yield (which is worth it on its own), but more importantly that boost is skewed towards times with low direct irradiance (such as cloudy days). This reduces the amount of storage required.

It also allows other orientations. Vertical installations have huge advantages including better compatibility with agrivoltaics, generation skewed towards times where low tilt panels don't produce (morning-evening for east-west and winter for north-south), better dual use, and lower racking cost. Glass-glass encapsulisation is also more durable and this alone pays for most of the added cost.

An inconvenient truth: you can’t sell the green revolution to people who can’t afford it | Gaby Hinsliff

This is just hostage shield politics.

If the author cared about the moped riders (they don't) then electric mopeds with a swappable battery pay back in a year of use.

If the author cared about the shift worker, then (e)bike lanes, all night bus routes, and electric busses are a solution instead of using them to block clean air zones (and continue killing theim with CVD from the pollution).

Subsidized mini splits for homeowners and electric heat as a condition of habitability for rentals are how to ease the burden there. Not saying "oh well, better subsidize oil furnaces".

Geometry hates cars

If the cars are moving at over 5m/s then there will be for minimum safe followong distance.

If they are moving under that, you don't have a transport system that is more capable than a brisk walk.

Why tires — not tailpipes — are spewing more pollution from your cars

Reply in thread

Sounds amazing and I hope one gets invented, but there is another solution as well:

You could make the wheels out of steel and run them on a narrow road also made of steel instead of oil byproducts, so they would wear out much slower, and any dust would be similar to naturally ocurring iron oxides (becoming relatively inert once it mixed with mud even if there was still some respiratory risk). It would be better suited to higher speeds and big loads and would compliment the other invention (maybe you could even put the small two wheeled car on the big steel wheeled car). Some kind of self-driving system would also be necessary to keep everyone safe
