"Warren Buffet-owned Berkshire Hathaway on list of top 25 companies with least efficient and oldest ‘sub-critical’ coal power plants "

"The 100 global power companies most at risk from growing pressure to shut highly polluting coal plants have been revealed in a new report from Oxford University.

Chinese companies dominate the top of the ranking but US companies, including Warren Buffett’s Berkshire Hathaway, occupy 10 of the top 25 places.
