This might not be an issue if [[wind/hydrogen]] (as described above) is the main solution. Instead of power lines, the wind turbines would generate [[hydrogen gas]] which would be [[hydrogen gas/shipping|transported]] and used for [[energy]] elsewhere. | This might not be an issue if [[wind/hydrogen]] (as described above) is the main solution.
