In an article in the Lanark Gazette recently, Tory MP David Mundell says that he does see "the odd windfarm" as part of a "mixed energy solution", but is against Scotland realizing the full potential of renewables. There are concerns that his "mixed energy solution" might include gas from unconventional sources such as shale gas, coalbed methane and coal gasification, but so Mr Mundell has not elaborated. These concerns seem well founded as recent reports in the national press show that his party has received a donation of £550,000 from a Mr Ian Taylor who is CEO of Vitol, a company which is a major shareholder in Dart Energy. Dart is the company which has applied to extract unconventional gas in Scotland, including at the test site at Canonbie in David Mundell's constituency where methane leaks are currently being investigated by SEPA. It's about time Mr Mundell told his constituents what he thinks a "mixed energy solution" should be.
