The cost of burying cables makes it prohibitive, even without the ease of maintenance provided by suspended high voltage lines.
Put in concentrated solar parks and ship the green electricity via high-voltage lines to the rest of Europe.
Transmission, especially long high-voltage lines that cross states, is extraordinarily hard to get approved, sited, permitted and paid for.

Main.net's system skips the high-voltage lines, injecting data into the grid further downstream, on medium-voltage (4, 000 to 25, 000 volts) lines.
Fort Knox began talking about solutions with Nolin Rural Electric Cooperative, which maintains the high-voltage lines bringing power to the base.
That is the reason why the current emphasis in China is on the construction of 500kv extra-high-voltage lines and long-distance power transmission.
By helping the base use existing juice supply more efficiently, the co-op can hold off on costly and more complicated investments in new high-voltage lines.
It also wants any new high voltage transmission lines to avoid areas of outstanding natural beauty, national parks, world heritage sites and green belt land.
Midwest ISO, which supervises 94, 000 miles of high-voltage lines, is considering ways to spread the costs of new transmission beyond local ratepayers and taking part in preparing a broad plan for the eastern interconnection.
The authorities blame unexpected storms, tree branches falling on high-voltage power lines (as in the Italian example) and other acts of nature.
Outages that used to last a few hours now can drag on for the better part of a week as repair crews contend with flooding, downed trees and snapped high-voltage power lines across vast regions.
Now there is growing concern that a really big storm might collapse much of the global electric grid, particularly in places with long high-voltage transmission lines such as Australia, Canada, China and the United States.
FORBES: Intelligence Community Warns Solar Storms Could Collapse Electric Grid
The network of high-voltage "transmission" lines in the U.S. is rapidly aging and no longer can adequately support the country's growing demand for electricity.
Infineon also provides the thyristor chips that allow transformers to handle high-voltage direct-current power lines.
