Some may carry five modern wind turbines and lift 700 tonnes 125 metres (410 ft) above deck. [5] [6] A vessel can cost [7] $335 million, or $220,000 per day. [8] A 3-year leasing may cost €90 million. [9] The fleet of 16 vessels are scheduled to expand to 23 vessels by 2023, of which seven can handle the largest turbines.
In addition, there is currently no competitive market for wind energy (though there may be in the future), because wind is a freely available natural resource, most of which is untapped. [115] The main cost of small wind turbines is the purchase and installation process, which averages between $48,000 and $65,000 per installation.
Wind power is considered a sustainable, renewable energy source, and has a much smaller impact on the environment compared to burning fossil fuels. Wind power is variable, so it needs energy storage or other dispatchable generation energy sources to attain a reliable supply of electricity. Land-based (onshore) wind farms have a greater visual ...
As a result, a number of offshore wind port facilities have been built in areas with a high concentration of offshore wind developments. [1] For large offshore wind farm projects, some offshore wind ports have become strategic hubs of the industry's supply chain. [2] The Port of Esbjerg in Denmark is considered the world's largest offshore wind ...
The energy consumed to manufacture and transport the materials used to build a wind power plant is equal to the new energy produced by the plant within a few months. [ 119 ] Onshore (on-land) wind farms can have a significant visual impact and impact on the landscape. [ 120 ]

Romania has a wind-power potential of around 14,000 MW, and an energy-generating capacity of 23 terawatt-hours. The country's wind power capacity that can be assimilated by the national transport grid is between 3,000 MW and 9,000 MW, while only in the last two years the total power of the requests for connecting to it was about 22.800 MW.
