Wind turbine lifetimes are 20 to 25 years at the best.
I agree for solar panels, they don't need lots of concrete and only loose efficiency over time. But you would need lots of them + a complete power storage system behind. So the cost and material used to have a similar power output is still order of magnitude higher.
> Modern wind energy systems, with good wind conditions, take 460 metric tons of steel and 870 cubic meters of concrete per megawatt.
