On Tuesday morning, between midnight and 4am, Britain generated no electricity from coal.

This is believed to be the first time since the 19th century. It marks a major milestone in the decline of the polluting power source.

Experts say that they believe that this was the first time there had been no coal running since the era of central electricity began, with the construction of the UK's first coal plant in 1882.

As recently as 2013 coal was Britain's biggest power source. However as this is becoming increasingly unprofitable its status as Britain's biggest power source is declining. Especially as The UK Government has announced plans to phase out coal by 2025.

Increasing carbon tax, low gas prices (that favour burning gas) and the expansion of subsidised renewable sources like wind power. This shift certainly wouldn't have been seen a few years back where oil and gas prices were much higher.
