Rosie Barnes on Off-shore wind

Yes – it’s twice as expensive as on-shore wind.

But it can be less visible (so less complaints and less environmentally destructive than on-shore wind. It also can be much larger, mainly because transporting the super-sized structures is easier by boat than by road. The ocean has stronger more stable winds – and so off-shore wind has a higher capacity factor works longer hours more reliably) than onshore wind. sometimes runs after dark when solar and much on-sh- which means it works longer hours more reliably. It often works after dark when solar and even some on-shore wind have stalled. Depending on location – it can be a great piece in the puzzle for a more reliable all-renewable grid.

Nice short piece by PBS on the population crash later this century

Kurzgesagt covers Nuclear Winter

It seems like some of the biggest Youtube channels have decided this really needs covering.

A truly horrifying subject!

(Um, Americans – vote Biden. He’s old – but at least he listens to input from his team! The “Narcissist in Chief” only listens to his own megalomania – and also seems to be showing some serious cognitive decline!)

Your part of a wind turbine blade is less than a bicycle!

Worried about recycling wind turbine blades? Today’s wind turbines are SO MASSIVE and generate so much power that the per-person amount of composite material used is less than a carbon fibre bicycle!

And they tend to last 25 to 30 years.

And they’re working on new recycling systems – even for this fibreglass.
