Matlådemåndag
As
forecast, this Monday brought rain and grey skies – in other words, perfect
weather for returning to work after the holidays. By lunchtime, I had already
scheduled dozens of meetings, prepared one more lecture, and realized just how
much of a crunch the coming autumn will be.
Meanwhile,
Roger Pielke published a fascinating new dashboard that allows you to calculate
the magnitude of the decarbonization challenge for different countries.
Extrapolating into the future, it becomes clear just how important assumptions
about future energy use are. On the one hand, there is spontaneous
decarbonization and continued improvements in energy efficiency; on the other,
there are new uses for electricity, like AI, and potentially a growing need for
things like air conditioning in a climate-changed world. Running the numbers
for Sweden and assuming that these opposing trends cancel each other out,
replacing all fossil primary energy would require the construction of eighteen new 1 GW
nuclear power plants (or a whopping 15,748 3 MW wind turbines). To achieve this
by 2050, emissions would have to fall by almost 17% per year, more than twice
the highest observed rate of reduction during the nuclear build-out of the
1980s.
To help
with the carbon math, I at least brought my own vegetarian lunch to work today:
a recipe from Tuvessonskan for mushroom ragù with white wine, thyme, and lemon
zest that I will definitely make again soon.
