while ok for classical physics, you might want to hedge your bets a tad on this one when it comes to general relativity and cosmology. no one has yet been able to formulate a totally agreeable/proper "book-keeping" procedure for conservation of *total* energy. there are papers written on this going back decades, but you won't find it mentioned in the public press.
