"King Coal is, almost overnight, being banished from Britain. When Drax opened for business in 1974, Britain got 80 percent of its electricity from burning coal. As recently as five years ago, the figure was 40 percent. But last year, it was 9 percent, and this summer coal supplied less than 2 percent of Britain’s electricity. On April 21, 2017, for the first time since its inception, the British power grid went 24 hours without coal. The zing in the power lines now comes almost entirely from natural gas, nuclear, and growing networks of giant wind turbines and solar farms. The government says all of the U.K.’s remaining coal plants will be shut by 2025 – maybe sooner. Drax will live on, but only by burning biomass – mostly wood chips imported from the southern United States... But it is the speed of King Coal’s demise in Britain – its first and most important stronghold – that is breathtaking, says Michael Grubb, energy analyst at University College London. It shows what can be done, even in an essentially market-based energy system such as operates in the U.K. Coal was the foundation of Britain’s rise as the dominant global power in the 18th and 19th centuries. It became the engine of the modern industrialized and urbanized world." e360.yale.edu/features/in-a-stunning-turnaround-britain-moves-to-end-the-burning-of-coalAmazing turnaround.

You might like the linked article about Britain's "greenest" summer "The Grid has launched software that forecasts the carbon intensity of electricity up to two days ahead. It hopes this will help people to understand and control energy use. Shifting the timing of activities such as running a dishwasher or charging electric vehicles could help relieve pressure on the energy system, reduce the need to use back-up fossil fuel plants, and potentially reduce bills for households. The software combines National Grid's knowledge of the energy system with weather data from the Met Office to forecast the share of renewable and non-renewable energy on the grid over the next 48 hours and the resulting carbon emissions. It is hoped that technology companies will then develop apps and software that could help people control when and what type of energy they use." www.bbc.co.uk/news/business-41397133

As long as they keep similar and diminishing %'s of generation from pellets as from coal, they will be on the right track. Once storage is cracked, it will be a non-issue. We've already beaten EIA estimates for where storage costs would be for 2017. EIA said $550/kwh and we're at about $250. As to pellets it depends on whether it's waste wood or new harvest. If it is waste wood, the deforestation concern is moot as the harvesting has already happened for other lumber purposes.
