UK power generation shifting away from coal

Many thanks to my student Ollie for spotting the news that the UK has just managed 55 hours without using coal for power generation, for the first time ever. Bloomberg reported on data compiled by the National Grid, which shows that went for a record 55 hours without its any of its power plants producing electricity by burning coal. Over the same period (Monday to Thursday this week), wind turbines produced more power.

The UK has massive investment in wind power; this is an aspect of government economic policy as the government aims to switch off all coal plants by 2025 and has given renewables priority access to the grid. With the comparative advantage of a long coastline, we have more offshore wind turbines installed than any other country, as well as fields of solar panels. This is successfully squeezing out the negative externalities of emissions from coal. 

On the other hand, there are many who protest against the negative externalities of wind and solar power and it's effect on sustaining the environment. Discuss!
