This week’s Question: The Department of Energy (DOE) has set a goal of building a battery that stores energy for less than $100 per kilowatt-hour, making stored wind and solar energy competitive with energy produced from traditional power plants. Today’s lead INSIDER story featured a new flow battery that offers the potential to significantly decrease the costs of production. "If you can get anywhere near this cost target then you change the world," said researcher Michael Aziz. "It becomes cost effective to put batteries in so many places. This research puts us one step closer to reaching that target." What do you think? Will "$100-per-killowatt-hours" batteries boost wind and solar energy efforts?
