"Energy consumption is loosely correlated with gross national product and climate, but there is a large difference even between the most highly developed countries, such as Japan and Germany with an energy consumption rate of 6 kW per person and the United States with an energy consumption rate of 11.4 kW per person. In developing countries, particularly those that are sub-tropical or tropical such as India, the per person energy use rate is closer to 0.7 kW. Bangladesh has the lowest consumption rate with 0.2 kW per person.

The US consumes 25% of the world's energy with a share of global GDP at 22% and a share of the world population at 4.59%.The most significant growth of energy consumption is currently taking place in China, which has been growing at 5.5% per year over the last 25 years. Its population of 1.3 billion people (19.6% of the world population) is consuming energy at a rate of 1.6 kW per person. [wiki]

Plenty of towns and cities in the countries mentioned here have hot and humid climates. But the US consumes 11.4kW per capita, while China, oft quoted as the major threat in global warming, consumes seven times less per capita. The US consumes twice as much almost per capita as even the biggest industrial nation in Europe, Germany. The US consumes 25% of the world's energy and has less than 5% of the population. Pretending that you're doing lots of environmentally-friendly things simply doesn't wash. Over four-fifths of your energy consumption comes from fossil fuels. The world has a big problem, and the US is a disproportionately large part of that problem. "
