How are solar flares dangerous for astronauts?

It takes solar flares 8 minutes to travel from the sun to the earth.
So why do astronauts have to react instantly when they observe a flare?

How much energy goes into making af wind turbine?

Does anyone have a calculation on how much energy goes into producing a wind turbine (offshore or onshore). Including things such as: steel production, unit production, assembly, transportation, erection, maintenance, etc? Compared to the amount of energy the wind turbine can produce in its lifespan?

Thank you
