How do you get to the top of a wind turbine? | RWE | 10 comments
How do you get to the top of a wind turbine? The door at the base is roughly the size of a wardrobe. What's behind it is 120 metres of vertical climb. Inside the tower, a fixed ladder runs the full h...

There is no shortage of ambition around wind energy, and the direction of travel isn’t the problem. The harder question is whether the assumptions used to turn that ambition into investment decisions are good enough for the 25 years that follow? teemuvekkeli.substack.com/p/wind-energ...

Wind Energy, Unfiltered #8: Beyond policy and ambition. What happens when assumptions meet reality?

After 20 years of operation, a wind turbine can still have years of useful life left, and yet become increasingly difficult and expensive to operate. Wind Energy, Unfiltered #6 is now available on Substack! teemuvekkeli.substack.com/p/wind-energ...
teemuvekkeli.substack.com
Wind Energy, Unfiltered #6: When does a wind turbine become obsolete? And what are the alternatives?
Does an asset become obsolete because it can no longer create value, or because it can no longer operate?

Wind Energy, Unfiltered #5 is available on Substack. Wind energy in 2026 is a different industry from the one I entered 20 years ago. What’s changed and what could be done differently? teemuvekkeli.substack.com/p/wind-energ...

Wind Energy, Unfiltered #5: What happened to wind energy? And are we still building for the long term?
The industry has grown up. But has it become more mature?

Wind Energy, Unfiltered #4 is now available on Substack. When the wind turbine isn’t working, the blades aren’t turning. Sounds straightforward, but for the people operating, financing and managing the wind farm, they can have very different consequences. teemuvekkeli.substack.com/p/wind-energ...
teemuvekkeli.substack.com
Wind Energy, Unfiltered #4: Is the wind turbine actually working? And whose problem is it anyway?
A 97% availability sounds precise. Until you ask what counts as unavailable.

Wind Energy, Unfiltered #3 is out now. How certain are we about how much energy a wind farm can actually produce? teemuvekkeli.substack.com/p/wind-energ...
teemuvekkeli.substack.com
Wind Energy, Unfiltered #3: Is there enough wind? And how would you know?
The real question isn't how windy a wind farm site is. It's how wrong your assumptions can afford to be.
