China NDRC's Top 1000 Enterprises' Energy Consumption by Sector in 2006

China's National Development and Reform Commission’s “Top 1,000 Enterprises Program” is central to its efforts to reduce national energy intensity by 20 percent. Established in its current form in 2006, this program imposes a significant portion of the overall 20 percent energy intensity target directly on China’s 1,000 largest state-owned enterprises, most of which are in heavy industry (see figure). In 2005 the enterprises in the program accounted for at least 33 percent of total primary energy demand and 47 percent of industrial energy demand.

Top Ten Coal Consuming Countries in 2008

Currently, about 83% of China’s electricity is produced by burning coal, and coal is expected to become an even more important source of electricity in the near future. In 2008, China burned more than double the amount of coal used in the United States, the world’s second largest consumer. China’s coal consumption is expected to grow as it moves to meet surging demand for electricity from industry and consumers.

Growth in Total Wind Capacity in China and the United States, 1998-2008

China is spending heavily to develop climate friendlier alternatives to coal, including nuclear, hydroelectric, solar and wind power. In the last few years alone, for instance, China has doubled its construction of wind turbines, and now has 10% of the world’s total.

Status of Building Energy Codes in the Southeast United States, February 2009

Several Southeast states have been leaders in adopting updated building energy codes, both for residential and commercial buildings. Other states are using outdated codes. Some have no codes at all. Even with building energy codes, a lack of enforcement and training can still prevent states from achieving actual savings. States can leverage federal funds to support programs that create advanced energy codes and ensure that buildings are meeting performance requirements.

Trends in U.S. Southeast and United States Energy Consumption, Population, Gross Domestic Product, and Related Indicators, 1997-2006

Between 1997 and 2006, total energy consumption in the Southeast (Alabama, Florida, Georgia, Mississippi, North Carolina, South Carolina, Tennessee, Virginia) increased 13 percent, more than double the national rate of 5 percent over this time period. Growth in energy consumption is largely attributable to increases in population and economic activity, specifically growth in personal income or GDP per capita (populous, industrialized regions typically have greater energy demands).

U.S. Southeast Ranks Among Top Global Energy Consumers in 2006

The U.S. Southeast--defined here as Alabama, Florida, Georgia, Mississippi, North Carolina, South Carolina, Tennessee, and Virginia--constitutes approximately one-fifth of the U.S. population and economy, and consequently, ranks among the largest energy consumers in the world (if the Southeast were a country, it would be the fifth largest energy consumer in the world). On a per capita basis, energy consumption is approximately equal to the national average, which is twice that of many European countries and nearly six times greater than that of developing countries such as China.

U.S. Southeast Fossil Fuel Consumption by Sector, 2006

In the U.S. Southeast (Alabama, Florida, Georgia, Mississippi, North Carolina, South Carolina, Tennessee, Virginia), coal is consumed mostly for electricity generation, petroleum for transportation, and natural gas for electricity generation and industry.

U.S. Southeast Energy Consumption by Fuel, 2006

As of 2006, the U.S. Southeast (Alabama, Florida, Georgia, Mississippi, North Carolina, South Carolina, Tennessee, Virginia) relied on fossil fuel sources for approximately 80 percent of its total energy consumption, a total that is similar to, but slightly below, the national average of 85 percent (the regional fuel mix is comprised of larger contributions from coal and nuclear sources and a smaller percentage of natural gas than the national average).

U.S. Southeast Electricity Generation by Source, 1997 and 2006

In the U.S. Southeast (defined here as Alabama, Florida, Georgia, Mississippi, North Carolina, South Carolina, Tennessee, and Virginia) from 1997 to 2006, total fossil fuel consumption increased approximately 14 percent, outpacing the national average rate of 5 percent growth. Southeast consumption of fossil fuels also exceeded the less than 1 percent growth in regional non-fossil energy sources (nuclear, hydroelectric, wood/waste, solar, wind, and geothermal sources).

Typical Range of Water Withdrawals and Consumption for Thermoelectric Power Plants

Some thermoelectric power plants employ “once-through” systems that draw water for cooling purposes and then treat and discharge the water. These require more withdrawals, but result in less total consumption. The opposite is often true for power plants that utilize ponds or cooling towers to reuse water through “closed-loop” systems. These require relatively less water in terms of withdrawals, but can ultimately consume more water through evaporation in the cooling process. Some newer plants (mostly natural gas-fired) use hybrid or dry cooling systems that consume little to no water.
