Good. That means more people now have access to it and it is a good thing.
Another example is clean water. If clean water is abundant, people will use it for more drinking and cooking and bathing. That is a good thing.
However, I should have been more specific when I said making air conditioning more efficient is counterproductive. I solely meant counterproductive towards the assumed goal of decarbonization in response to the prior comment's claim that "finding efficient ways to use our energy" is a viable strategy to address climate change.
Without pairing that efficiency with real solutions like putting a price on negative externalities, increasing efficiency is significantly more likely to increase overall energy consumption than to decrease it.
