To achieve the desired quality of life, people need about 3,000 kW hrs/yr

Two Truths:1) World population is rapidly increasing2) As the standards of living rise, global electricity usage per capita will also increase

The Result:Large increase in demand for electrical energy at the same time we must address climate change
