Electric food, the new scifi diet that could save our planet – George Monbiot.

The most important environmental action we can take is to reduce the area of land and sea used by farming and fishing. This means, above all, switching to a plant-based diet: research published in the journal Science shows that cutting out animal products would reduce the global requirement for farmland by 76%. It would also give us a fair chance of feeding the world. Grass-fed meat, contrary to popular belief, is no alternative: it is an astonishingly wasteful use of vast tracts of land that would otherwise support wildlife and wild ecosystems.

Could we go beyond even a plant-based diet? Could we go beyond agriculture itself? What if, instead of producing food from soil, we were to produce it from air? What if, instead of basing our nutrition on photosynthesis, we were to use electricity to fuel a process whose conversion of sunlight into food is 10 times more efficient?

This sounds like science fiction, but it is already approaching commercialisation. For the past year, a group of Finnish researchers has been producing food without either animals or plants. Their only ingredients are hydrogen-oxidising bacteria, electricity from solar panels, a small amount of water, carbon dioxide drawn from the air, nitrogen and trace quantities of minerals such as calcium, sodium, potassium and zinc. The food they have produced is 50% to 60% protein; the rest is carbohydrate and fat. They have started a company (Solar Foods) that seeks to open its first factory in 2021. This week it was selected as an incubation project by the European Space Agency.
