Someone asked me yesterday if the discovery nuclear fusion will mean we won't need degrowth anymore.
On the contrary, I think it underlines why degrowth is so important.
These 4 graphs show why.

The short of it is, even if we invent a source of unlimited free energy, we are already crossing the boundaries of countless life support systems other than the carbon cycle.
In 2015, we had already crossed 3 planetary boundaries, including biodiversity.

Free energy won't solve that, we'll still need to transform and radically reduce our global material and energy use and destruction of ecosystems. In fact, it might speed it up.

You're about to hear a lot about #NuclearFusion. I've followed the field for years & can offer context. Top line:
- NIF's "breakeven" does not generate more power than it consumes
- NIF is not a model for a commercial fusion reactor
- This news is a big deal all the same. 1/n

Fusion researchers measure fusion output in "Q," the ratio of power produced to power needed to maintain the fusion plasma. NIF has exceeded Q=1.
Breakeven, right? Er, the accounting is not so simple, as Charles Seife explains. 2/n theatlantic.com/technology/arcā¦ #fusion #NIF

The power that goes into igniting a fusion pellet is much less than the total amount that NIF consumes. "Breakeven" comes nowhere close to covering all of that consumption! A useful fusion power plant would require anything from Q=5 to Q=100. 3/n

Get excited... press conference from @ENERGY on fusion results from the US National Ignition Facility @lasers_llnl on Tuesday with a potentially HUGE #nuclearfusion announcement: FT reporting that NIF has hit scientific net energy gain!

Rumours have been circulating that this is what happened but I understand no official confirmation as yetābut numbers might be as much as 120% of net energy gain.
If this is true, we are witnessing a moment of history: controlling the power source of the stars is the greatest..

technological challenge humanity has ever undertaken. Scientists have struggled to show that fusion can release more energy out than is put in since the 1950s, and the researchers at Lawrence Livermore seem to have finally and absolutely smashed this decades-old goal. This...
Nuclear fusion is much closer than you think!

First, what is nuclear fusion? It's a reaction that literally creates new atoms from old: lighter nuclei (say types of hydrogen) are smashed together to make heavier nucleiāand LOTS of energy. And the energy comes from an equation you already know! (Yes the one by Einstein)
You should care about fusion: apart from being the reaction that makes the Universe light up (powering stars) and the reaction that created most of the elements we're made of, fusion promises clean, safe, low radioactivity energy for everyoneāand wow do we need more clean energy

#BREAKING #fusion #news: The National Ignition Facility (@LLnL) has reported a *twenty-five times* increase in energy released as compared to their 2018 world record for laser fusion: 1.3 MJ out for 1.92 MJ in, a 67.7% gain in energy!! š¤Æ

This is MASSIVE. Itās so close to energy breakeven that itās now almost inevitable that NIF will make history and be the first to hit 100%, showing that #fusion is not just a power source for the stars, but that it *could* work on Earth too. Here I am touring the NIF with Bruno:
Iāve long rated the chances of NIF of getting there 1st, simply because they have a machine thatāin principleāhas the size and science to do it right now. (I give serious love & attention to this giant laser & the people behind it in #TheStarBuilders)

Wow-1g of deuterium-tritium produces, through #nuclearfusion, as much energy as the combustion of 8000 tonnes of oil!
Hear that, #Fridays4Future #Davos2020 !!

In 2003 the Tore Supra maintained a plasma pulse for 6min 30sec that produced 1billion Joules of energy-a world record among tokamaks that still stands today.
