Tesla Plans To Power Its Gigafactory With Renewables Alone

AmiMoJo writes In his press conference, Elon Musk stated that the factory will produce all of its own energy using a combination of solar, wind, and geothermal. Engineering.com looks at the feasibility of the plans. Spoiler alert: it looks possible, though some storage will be required. Fortunately, if there is one thing the Gigafactory won't be short of it's batteries. From the article: "The numbers don’t lie. The site could realistically produce more than 2900 MWh of renewable electricity each day ... 20% more than it needs. These are conservative estimates on production and worst-case estimates on consumption, and it’s clear that there’s enough renewable energy to run the plant with some to spare."

      Tesla is going to produce, on average, enough energy to run the gigafactory without getting any externally-created electricity. In reality, sometimes Tesla will not create enough energy, so it will draw from the grid. On the other hand, sometimes it will produce too much, and that goes back to the grid, where it is used elsewhere. The energy used elsewhere is used instead of fossil fuel-produced energy. Therefore, effectively, carbon emissions from energy production will be zero (though, as you say, their equipment will produce produce greenhouse gases).
