d. overwhelming public ignorance of conservation issues.
e. the fact that energy conservation techniques are quite expensive.

Technological inefficiency.

Explanation:

The energy in North America is wasted based on the facts that the efficiency of the technology is not upto the mark. In this case the waste generation of energy takes place.

This is because the total energy that is generated cannot be stored in such a way that it can be used in future.

The wastes generation is more rather than the consumption as there is so much of the technological  inefficiency there in North America.
