How will population growth affect energy?

Population's Link to Energy

So, are population and energy consumption related? Unfortunately, yes. Although wealthier countries are not growing at as fast a rate as developing nations, they’re still growing. And, as each human is added to the Earth, resources become more of a precious commodity -- especially nonrenewable ones like fossil fuels, which provide most of the world’s energy. Consider this: If the United States consumes 20 percent of the world’s energy now, how much energy will the country consume if it reaches the United Nations' projected population of 450 million by the year 2050?

Our insatiable appetite for energy across the globe contributes to deforestation, global warming and other environmental issues like pollution and acid rain. In the United States, 40 percent of our water resources are already so polluted, they're unsafe for fishing or cannot support aquatic life.
