what a fucking catch <| sep |> Battery packs will be extremely useful in Nordic regions because of their use of wind generation . Having a grid that can store large amounts of energy for use during periods where the wind generation isn ' t as great will help them continue using green energy sources as the main supply . Probably the biggest detriment to solar and wind and some hydro was that the power generation wasn ' t consistent enough to power the grid continuously , but the battery packs are a great solution to that ! Other options considered have been thermal storage and potential storage , but those are more complicated and would require secondary methods of power generation onsite , while a battery can just charge and discharge . I love where this is going ! I ' m really excited about the future as long as the US government doesn ' t succeed in fucking things up over the next 4 years .
