Plans for coal-fired power plants drop by almost half in 2016

The authors of a new study say there was a 48% fall in planned coal units, with a 62% drop in construction starts. The report, from several green campaign groups, claims changing policies and economic conditions in China and India were behind the decline. However, the coal industry argues the fuel will remain essential to economic growth in Asia for decades to come.

Between 2006 and 2016, India and China together accounted for 85% of the coal plants built around the world. But according to the Boom and Bust 2017 report, put together by Greenpeace, the Sierra Club and CoalSwarm, there has been a huge swing away from coal in these two countries in just 12 months.

"Amidst political tensions, an estimated 18 million people across DPRK [North Korea] continue to suffer from food insecurity and undernutrition, as well as a lack of access to basic services," the UN report said.

Scotland sets 50% renewable energy target

The draft Scottish Energy Strategy sets out a vision for the transition away from oil and gas dependency and towards a low-carbon economy by 2050. Only 13% of Scotland's total final energy consumption came from renewable sources in 2013. Environmental groups had been campaigning for the 50% target. A public consultation on the proposals will run until the end of May. 'Fuel poverty' Last week, the Scottish government set a new target of reducing greenhouse gas emissions by 66% by 2032. Its energy strategy, which was unveiled by Energy Minister Paul Wheelhouse at Holyrood, includes exploring the "re-powering" of existing power stations, which could see Longannet reopen as a coal-fired station with Carbon Capture and Storage (CCS).

Census shows agricultural workforce falls to record low. Image copyright PA Scotland's agricultural workforce has fallen to its lowest level on record, according to official figures.

Census shows agricultural workforce falls to record low

The June 2016 farming census found 63,400 people were employed on agricultural holdings. That was 1,900, or 3%, fewer than the previous year and the lowest figure since current records began in 1982. Scotland's chief statistician largely attributed the fall to a drop in the number of working occupiers, which fell by 1,200, or 3.3%. Working occupiers made up 58% of total workers, with regular staff accounting for 32%.
