Biodegradable ester oil for transformers?

A high-voltage transformer in the main grid may contain as much as 100 tonnes of mineral oil, which is used as an electrical insulator and cooling medium. The environmental risks associated with transformer oils are very unlikely to be realised, but it is still necessary to make contingencies for them.
