First of all, @Mike_Page is right that electric motors are actually more efficient at turning calories into motion than humans. So if we would replace heavy electric trucks with an army of cyclists, this would indeed not be good for the climate and require too much food.
Second of all, I think it's probably true when you compare an electric bike to a car but the 30g/km for a vegan like me is clearly less than for an electric car (~50g/km for manufacturing plus ~40g/km for driving in the EU) and you have to add my CO2 emissions as car driver.
Finally I'm pretty sure the avoided healthcare costs and other societal costs that result from switching from car to bike outweigh the CO2 emissions from biking, both in terms of costs and CO2.
The only thing you could say is that biking is healthy and if that means you live longer, your total CO2 emissions rise. But if you say a person should not bike for that reason I consider you to be 'off the reservation' as they say.

GEOTHERMAL
Just saw a fascinating webinar and you should too if geothermal interests you.
It explains how techniques from fracking are creating a game-changer in the last few years that can reduce the cost of energy systems without fossil fuels.
🧵
The webinar by prof. Roland Horne from @Stanford is about Enhanced Geothermal Systems or EGS that he defines as using fracking to make the area between the infusion and extraction well permeable for water.
He focuses on @fervoenergy, a company founded by two @Stanford alumni (one from his program) that has for the first time in history used the horizontal boring technique from fracking in geothermal.
This eviscerates the last credibility of @Toyota regarding EVs.
They (esp. Gill Pratt) have been pushing the story we should buy their hybrids instead of full EVs because lithium batteries are and will stay the bottleneck
Grid congestion is THE bottleneck for economic growth and sustainability in the Netherlands.
But it doesn't have to be!
When we combine Dynamic Line Rating with Peak Shaving we could move three times more electricity with the current grid!
🧵
What is Peak Shaving?
Peak shaving means that you take measures to lower the peaks in electricity usage. Peaks are what limits use of a power line. In the example graph below you can see the demand is too high a few yours per week. But there is more than enough capacity overall
Adjusting only the 2.5% of electricity demand that causes the biggest peaks adds 25% of capacity.
Removing 17% of energy from the peaks (e.g. with dynamic pricing, batteries, smart charging, etc. etc.) provides 50% more capacity.
