I guess 140m high trees must be redwoods?

"The proposed wind farm
The wind farm would comprise 234 turbines, each 140 m tall. In addition, the developers are seeking permission to build 167 km of roads, nine electrical substations and a control building. Some 210 pylons would be needed to support the 56 km of overhead cable that would transport the electricity produced by the turbines. This network of turbines, roads and pylons would stretch from Stornoway to Ness (approx 40 km).

Each turbine would need a concrete foundation of approximately 1,800 m2 and next to it an area of 'hardstanding' for the installation cranes to use. Rock needed to construct roads, hardstandings and foundations will require the creation of at least five quarries or 'borrow-pits'."
