a. a failure to turn off lights.
b. technological inefficiency.
c. the fact that more efficient energy conversion is not possible.
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.

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.
