From New Scientist:
More energy is wasted in the perfectly edible food discarded by people in the US each yearÂ than is extracted annually from the oil and gas reserves off the nation’s coastlines.
Recent estimates suggest that 16 per cent of the energy consumed in the US is used to produce food. Yet at least 25 per cent of food is wasted each year. Michael Webber and Amanda Cuellar at theÂ Center for International Energy and Environmental Policy at the University of Texas at Austin calculate that this is the equivalent of about 2150 trillion kilojoules lost each year.
That’s more than could be gained from many popular strategies to improve energy efficiency. It is also more than projections for how much energy the US could produce by making ethanol biofuel from grains.
