Common Theme: Rapid Decline in Costs https://www.greentechmedia.com/articles/read/everyone-is-revising-electric-vehicle-forecasts-upward So why exactly is the forecast changing so drastically? Battery costs are coming down fast. We're already ahead of lithium-ion battery costs projected For 2030. And with 10 battery gigafactories under development around the world, battery costs and prices are expected to further outpace projections. Wood Mackenzie predicted that the cost of battery storage would decline to $200/KWh by 2030. As you can see in the graph, Tesla, with GM and Nissan closely behind, has surpassed that mark.
