The first time you see a Nemoi wind turbine, you may not realize it’s a turbine at all. A white and silver metallic structure about the size of a garden shrub, Nemoi has three vertical blades that spin carousel-like around a central axis. The spinning is constant, but completely silent, and it doesn’t look fast enough to be generating much energy. But appearances can be deceiving. According to its creator, Semtive Energy CEO Ignacio Juarez, a Nemoi turbine can power a four-person household at wind speeds of just 10-13 miles per hour. It’s also made of 95 percent recyclable aluminum, can be quickly assembled by one person, and is locally manufactured. Nemoi was created by energy startup Semtive, and with great timing—the International Energy Agency’s 2016 medium-term forecast for renewables predicts that by 2021, 60 percent of the world’s energy will come from renewables, and between now and then, wind turbines will go up at a rate of 2.5 every hour. To really make renewables widespread, though, they need to be more accessible. This has already started to happen with solar, as evidenced by the panels you may see on your neighbors’ roofs. Wind is just as abundant as sunlight, but it’s been harder to adopt on a local scale, and that’s part of the problem Nemoi’s creators are trying to solve. During a visit to Semtive’s office in Mountain View, Juarez told me about his motivation for building Nemoi, and his vision of decentralized, user-generated clean energy.
