The crucial number in this context is the electricity consumption of electric cars under street conditions.
The biogas produced 880 electric mWh, the annual electricity consumption of 250 houses, and a heat production of 847 thermal mWh.
How does this compare with the electricity consumption of others?
Some sources of farm emissions, such as the electricity consumption of a milking shed, can be measured directly.
For example, the school has what it calls the 100 Club Challenge, where everyone attempts to keep the electricity consumption of the school below 100 kWh a day.
(Cox writes that, by 2014, the U.S. computer network alone will each year require an amount of energy equivalent to the total electricity consumption of Australia).
It takes approximately 6.34 GW hours of energy to treat this volume of sewage, almost 1% of the average daily electricity consumption of England and Wales".
But the increase alone in China's power demand over the past two years has approximated the total electricity consumption of Brazil.
The US engineering firm Parsons Brinckerhoff (PB) has been hired by the Department of Energy and Climate Change (Decc) to assess technologies that could meet, from the Severn estuary, up to 7% of the electricity consumption of England and Wales.
More than 23,000 solar panels will be floated by developer Lightsource Renewable Energy at the reservoir near Walton-on-Thames, representing 6.3MW of capacity, or enough to generate the equivalent electricity consumption of about 1,800 homes.
The upgrade to the liquefaction plant will result in an increase to hourly liquid litre production of 70%, reducing the electricity consumption of the plant substantially, and therefore reducing plant running hours by a third.
