February 2021, information on the Promote Shetland Web site indicated that "Shetland is less reliant on tourism than many Scottish islands" and that oil was an important sector of the economy. The "process of gradually transitioning from oil to clean renewable energy ... production of clean hydrogen" was also emphasized. Fishing remained the primary sector and was expected to grow. Fishing Fishing is central to the islands' economy today, with the total catch being in 2009, valued at over £73.2 million. Atlantic mackerel makes up more than half of the catch in Shetland by weight and value, and there are significant landings of haddock, cod, herring, whiting, monkfish and shellfish. A report published in October 2020 was optimistic about the future of this sector in: "With new fish markets in Lerwick and Scalloway, and plans to expand its aquaculture offerings in Yell, Shetland is preparing for more growth in its biggest industry". As of February 2021, the Promote Shetland Web site stated that "more fish is landed in Shetland than in England, Wales and Northern Ireland combined', that "Shetland harvests 40,000 tonnes of salmon a year, worth £180 million" and that "6,500 tonnes of mussels are grown in Shetland, more than 80 per cent of the total Scottish production". Energy and fossil fuels Oil and gas were first landed in 1978 at Sullom Voe, which has subsequently become one of the largest terminals in Europe. Taxes from the oil have increased public sector spending on social welfare, art, sport, environmental measures and financial development. Three quarters of the islands' workforce is employed in the service sector, and the Shetland Islands Council alone accounted for 27.9% of output in 2003. Shetland's access to oil revenues has funded the Shetland Charitable Trust, which in turn funds a wide variety of local programmes. The balance of the fund in 2011 was £217 million, i.e., about £9,500 per head. In January 2007, the Shetland Islands Council signed a partnership agreement with Scottish and Southern Energy for the Viking Wind Farm, a 200-turbine wind farm and subsea cable. This renewable energy project would produce about 600 megawatts and contribute about £20 million to the Shetland economy per year. The plan met with significant opposition within the islands, primarily resulting from the anticipated visual impact of the development. The PURE project in Unst is a research centre which uses a combination of wind power and fuel
