As many energy comparison customers are aware, the UK is in need of finding new sources of cheap energy.
Now scientists at the University of East Anglia may have hit upon a way to generate electricity from bacteria.
A study shows how bacterial cells can transfer electrical charges, meaning researchers could find ways to 'tether' bacteria to electrodes.
Dr Clarke of the university's School of Biological Sciences commented: "This is an exciting advance in our understanding of how some bacterial species move electrons from the inside to the outside of a cell."
He added: "Identifying the precise molecular structure of the key proteins involved in this process is a crucial step towards tapping into microbes as a viable future source of electricity."
Customers could switch to renewable energy tariffs if they want to become more eco-friendly.
