But none of that is enough, practically speaking, because of one enormous hitch: The world is still using more energy each year, our consumption ticking ever upward, swallowing any gains made by renewable energy. Emissions are still rising—more slowly than they used to but, nonetheless, rising. Instead of getting pushed down, that needle is fitfully jiggling above zero, clawing into the positive digits when it needs to be deeply pitched into the negative. We are, in other words, simply not making a dent.
