Reliability tends to be in opposition to efficiency for mechanical stuff. Yeah, it sucks more energy which is bad, but if you use 50% less stuff for an efficient unit but end up replacing it 4 times while the old one still runs you end up using more materials.
We need a happy medium between as efficient as possible but only last for a few years and reliable but very inefficient.
Although hugely inefficient in both materials and energy.
