A dairy farm in California said yesterday that it had found a new way to generate electricity for households — using a vat of liquid cow manure.

Scientists say that controlling methane emissions from animals such as cows will be hugely important in preventing climate change.
Methane can also be captured and treated to produce renewable gas, which can be used instead of coal to run electricity-generating plants.
