The so-called breakdown of Dennard Scaling happened a little over 10 years ago. Since that time, CPUs have been forced to keep portions of the die powered off at any specific point in time - to prevent melting themselves. Each new generation requires a larger and larger area to be shut off.
Responsible use of energy directly leads to higher performance. You can also restate this: software is a performance bottleneck in a modern CPU.
