How can power lines be protected against strong winds?

And rubber power lines so they bend when the trees fall on them ;-)

It sure does!

Don't wind mills have to be turned off during wind storms? IIRC some Irish windmills were damaged and some knocked over during Storm Eowyn. As for Solar, how does solar power help anything during dark winter times - let alone during a hurricane?

Since the late 90's there have been grants to plant trees in Ireland, that still continue to this day.
It ended up increasing forrest cover from about 1% to around 11/12% and is estimated to get to around 20% in a few decades time.

The orginal thinking was that these would act as Carbon syncs and also provide wood.
The also would be ecologically better than farm land.

But like everything else in Ireland, there's a stack of problems/gotchas/no joined up thinking or planning.
1: It turns out carbon syncs don't work nearly as well as it was orginally thought. (Some argue they don't work at all)
2: The same type of tree is used for nearly all forrests, hence it's not ecologically diverse.
3: The trees are planted to close together. The trees at the edge of the forrest are strong, but the inner trees are very weak.
4: The over planting of trees has made the ground very acidic and nothing else grows.
5: The forrests are often planted in areas with lots of power lines, when the weak trees fall they take em out.

These forrests are approaching harvest having been growing for 30 years, the Trees are tall, straight, weak and in many cases are close to powerlines... accident waiting to happen.

These are commercial forrests designed to produce wood as fast as possible 20/30 year investment.
It may as well be farming.

You tell a farmer that they can't plant trees within 100ft of a powerline and see how far ya go.
