From a German perspective it sounds a bit weird, I mean, can there be any good argument against greater energy efficiency? Even if there was no climate change, why waste energy?
Several notes, with me agreeing that energy shouldn't be needlessly wasted.
1. Most people don't want to spend money on any energy they don't need. Companies lose profits, people lose their hard earned paychecks. It is in everyones best interest to use energy wisely.
2. Future tech being more efficient does not mean we are being intentionally wasteful now.
3. The real issue here is people having to pay extra for sped up tech research on technologies that may or may not be ready yet (or the infrastructure is not there yet, see what happened to T Boone Pickuns), paying extra for carbon credits which are just profit centers for a few smaller companies (and the consumer ends up paying for), etc.
4. Seeing as the world is out of control with debt now, people using their pickups for 2 years to save up for a new car is far better than everyone going into debt on buying new cars. That is good fiscal responsibility.
5. The climate change issue puts everyone in panic mode, so more money is wasted on rushed ideas and research, with no proper testing and oversight. That's fiscal waste, and possibly bad for the environment as well. Stepping back to re-assess is a good thing.
