same year, 25% was from renewable sources, up from 22% in 2017. Electricity generation encompasses a broad mix of technologies including Coal (e.g. Aberthaw), Gas (e.g. Baglan Bay), Wind (Cefn Croes), hydro-electricity (Dinorwig), solar thermal/PV and biomass electricity. In 2017, the Welsh Government announced a target of meeting 70% of Wales’ electricity demand from Welsh renewable electricity sources by 2030. By 2018, Wales generated over 3,864 MW renewable energy from 68,728 projects. In June 2018 the Welsh Government backed the Tidal Lagoon Swansea Bay project with an offer to invest £200 million; the project would see the world's largest tidal hydro-electricity plant. However, in June 2018, the UK Government refused to back the plan due to it being shown to be not viable by an indepentent report. In 2021, the Welsh government said that more than half the country's energy needs were being met by renewable sources, 2 percent of which was from 363 hydropower projects. Food and drink The food and drink sector is classed as a priority economic sector in Wales. It involves 170,000 people that contribute to gross sales of £17.3 billion. The largest private sector employer is the Cardiff brewer and pub owner Brains Brewery, which employs nearly 1,800 people. Forestry Forest and woodland makes up 14% of the land area of Wales and there are 4,000 jobs and in forest-based industries. Healthcare Healthcare in Wales is mainly provided by the Welsh public health service, NHS Wales. NHS Wales provides healthcare to all permanent residents that is free at the point of need and paid for from general taxation. Health is a matter that is devolved, and considerable differences are now developing between the public healthcare systems in the different countries of the United Kingdom, collectively the National Health Service (NHS). Though the public system dominates healthcare provision, private health care and a wide variety of alternative and complementary treatments are available for those willing to pay.
