The amount of energy wasted depends on how high the block reward and the transaction fees are. The block reward is going down over time and transaction fees are unlikely to grow beyond a practical maximum.

Transaction fees will have to go up to compensate, else Bitcoin will become insecure as its resistance to 51% attacks falls below critical levels. See discussion at [1].
