The regulatory picture, very rarely in perfect focus, has been especially fuzzy in recent years and looks likely to remain that way a bit longer. We lead off this newsletter with word of a legal challenge to the Trump administration's recent rollback of greenhouse gas regulations. From there, we head offshore, hear from a prominent CEO on the big picture, and update you on developments in battery technology. As always, we're focused on bringing you a wide range of energy news.
