Bacteria that live off of Electrons

Unlike any other living thing on Earth, electric bacteria use energy in its purest form – naked electricity in the shape of electrons harvested from rocks and metals. We already knew about two types, Shewanella and Geobacter. Now, biologists are showing that they can entice many more out of rocks and marine mud by tempting them with a bit of electrical juice. Experiments growing bacteria on battery electrodes demonstrate that these novel, mind-boggling forms of life are essentially eating and excreting electricity.

Portugal Just Went 4 Straight Days Running Completely On Renewable Energy | Collective-Evolution

According to recent numbers released by Portugal’s ZERO System Sustainable Land Association in collaboration with the Portuguese Renewable Energy Association (APREN), the country ran solely on renewable energy for a total of four days this month. This 107-hour run began Saturday morning, May 7, and ended early Wednesday evening, May 11. Solar, wind, and hydro electricity were the renewable sources used during this record-setting event.
