Severn Trent, the UK water company, has revealed plans to invest some £190 million ($250 million) in on-site renewable energy generation over the next five years, in particular focusing on solar and anaerobic digestion.

The company says it expects to meet around half of its energy demand with renewable sources under the programme, from the 28% currently.

‘This will provide efficient green energy and a long-term hedge against volatile market prices,’ the company said in a statement.
