The difference between one man and another is not mere ability - it is energy

The difference between one man and another is not mere ability . . . it is energy.

The man who can speak acceptably is usually given credit for an ability out of all proportion to what he really possesses.

An idea isn't worth much until a man is found who has the energy and ability to make it work.

Probably the most critical impact of higher energy prices is their ability to weaken consumer spending.

The pace of development is outstripping our ability to manage the environmental issue. Our unwritten energy policy is dig it up and sell it as fast as possible.
