A sea breeze or onshore breeze is a gentle wind that develops over bodies of water near land due to differences in air pressure created by their different heat capacity. It is a common occurrence along coasts during the morning as solar radiation heats the land more quickly than the water. A land breeze or offshore breeze is the reverse effect, caused by land cooling more quickly than water in the evening. The sea breeze dissipates and the wind flows from the land towards the sea. Both are important factors in coastal regions' prevailing winds.
Offshore wind refers more generally to any wind over open water. Offshore wind farms take advantage of the higher wind speeds available over the sea, but are usually placed near coasts to reduce costs and to take advantage of daily flows of sea and land breezes. Nearshore wind farms are those closest to land, while others are further out to sea.
The sea has a greater heat capacity than land, so the surface of the sea warms up more slowly than the land's surface. As the temperature of the surface of the land rises, the land heats the air above it by conduction. The warm air is less dense and so it expands, decreasing the pressure over the land near the coast. The air above the sea has a relatively higher pressure, causing air near the coast to flow towards the lower pressure over land. The strength of the sea breeze is directly proportional to the temperature difference between the land and the sea. If a strong offshore wind is present, that is, a wind greater than 8 knots (15km/h) and opposing the direction of a possible sea breeze, the sea breeze is not likely to develop.
Adding to the wind industry’s woes, its claims that offshore wind power is ‘free’ and getting cheaper all the time have been totally torched – again. Over the last two years, Andrew Montford has been keeping a close eye on the financial reports produced by the UK’s offshore wind power outfits ... New data on offshore wind costs.
an energy crisis that has gripped Europe and Asia... In Europe, the energy shortages were made worse by low wind speeds in the North Sea, which for a time drastically reduced the electricity produced by offshore wind turbines for Britain and Northern Europe ... Plastics are used in wind ...
Projects already underway to generate electricity from renewable energy sources include the participation in the Hollandse Kust Zuid wind farm with Vattenfall, as well as the wind farm planned with RWE in the GermanNorth Sea ... In addition, BASF has recently signed a first long-term PPA for the supply of offshore wind in Europe with Ørsted.
Cross-border connections improve the energy islands’ proposition and will bring more offshore wind to the European electricity system ... “Connecting offshore wind projects to more than one country will improve electricity flows across Europe,” commented Wind Europe chief executive Giles Dickson.
The fact is, 25% of Europe’s offshore wind blows around the shores of Scotland. That is why there is 4GW of offshore wind either operational or under construction, and another 6GW in the pipeline – and offshore wind is going to play a massive part in the development of Scotland’s hydrogen sector.
Offshore wind turbine manufacturer Vestas has become the latest victim of a cyberattack after its ... Vestas, which is in the process of testing the tallest and most powerful offshore wind turbine in the world, recently shut down three factories in Europe to cut down on costs.
“The project will utilise floating offshore wind technology to produce zero-carbon electricity and will greatly help Ireland progress towards a green energy future with domestically sourced sustainable electricity, ...ShellEuropeOffshoreWind general manager Hessel de Jong said.
Together with Scottish researchers, AkerOffshoreWind is leading a consortium that will implement the GBP-2-million three-year project ... Aker Offshore Wind supports the call by tade body WindEurope for a Europe-wide landfill ban on decommissioned wind turbine blades by 2025.
AkerOffshoreWind has pledged its support to trade body WindEurope’s call for a Europe-wide landfill ban on decommissioned wind turbine blades by 2025, and considers the project a ‘crucial step toward setting a new standard for the industry’. In a statement, Sian Lloyd-Rees, managing director of Aker Offshore Wind UK said.
All over Europe, developers are looking to build large offshore wind farms, and in the UK and Denmark, for example, they can currently offer a much more attractive legislative process, with lower risk ... They are now trying to create a unified planning procedure for offshore wind, ...
This is the second Irish offshore wind project on ... Hessel de Jong, offshore wind general manager Europe at Shell, said the acquisition is in line with the group’s ambition to achieve net-zero emissions by 2050 and its aim to provide more renewable power to consumers and businesses.
“Simply BlueGroup are committed to developing floating offshore wind projects in Ireland.” Second deal ... “Shell has a clear ambition to be a net-zero emissions energy business by 2050, in step with society,” said Shell’s offshore wind general manager in Europe, Hessel de Jong.
Offshore wind will play a prominent role. By 2030, RWE intends to triple its offshore wind capacity from 2.4 GW to 8 GW, focusing primarily on Europe, North America and Asia, where the company works together with partners.
By the end of the decade, the Essen-based energy major aims to triple its offshore wind capacity to 8 GW from 2.4 GW primarily in Europe, North America and Asia and reach 2 GW of electrolyser capacity for green hydrogen production.
