United States Solar Radiation Map

Solar photovoltaic systems generate electricity using technologies that capture the energy in sunlight. Many parts of the United States—especially the Southwest—have abundant solar resources (see Figure 5, which shows estimates of the average daily total radiation for flat plate solar collectors). Before investing, however, firms should commission a thorough professional study of a specific site’s solar resources. Even if it reveals lower or moderate resources, solar power could still be financially attractive, depending on financial incentives and regulatory context.

United States Wind Resource Map

Wind energy systems generate electricity by using turbines to capture the wind’s energy. Many locations in the United States have good wind resources. Evaluating the quality of the wind resource at a specific site is critical to determining if it is suitable. Before making any investment decision, companies should commission a professional wind study, which evaluates the quality and consistency of a site’s wind resource potential.

Net Emission Reductions Under Cap-and-Trade Proposals in the 111th Congress, 2005-2050

This chart shows total net GHG reductions achieved by H.R.2454, S. 1733 and S. 2877 relative to U.S. historic and projected emissions as of December 17, 2009. For more information, see http://www.wri.org/publication/usclimatetargets.

New Supercritical and Ultra-Supercritical Coal-Fired Power Plants Installed Annually by Capacity from 1959 to 2007

In 2008, China's National Development and Reform Commission adopted a standard requiring all new coal-fired power plants to be state-of-the-art commercially available or better technology. As a result, today most of the world’s most efficient (supercritical and ultra-supercritical) coal-fired power plants are being built in China.

Comparison of Chinese and U.S. Energy Statistics

Today, each Chinese citizen produces only one-fifth the GHG emissions of an average American consumer, and China still has many unmet energy needs. Most Chinese have a much lower standard of living than the average American. Half the Chinese population has no access to winter heating, and most have limited access to motorized transportation. Therefore, the challenge for China in the short term is to reduce the rate of growth of its GHG emissions as it strives to meet the growing energy demands of its people.

Average Coal-Fired Power Plant Fleet Efficiency in China and the United States, 1949 to 2006

Improving energy efficiency and reducing carbon intensity in the power sector have been major goals for the Chinese government. This trend contrasts with the United States, where new coal-fired power plants built in the 1980s and 1990s were actually less efficient than those built in the 1970s. While China is still increasing its overall electricity output at a rapid rate - slightly more than one power plant per week - new power plants both add to capacity and replace less efficient, smaller power plants and direct (and very dirty) coal-burning at industrial sites.

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.

U.S. Energy Intensity by Industry

American manufacturers fear that the imbalances created by aggressive climate policy in the United States could contribute significantly to the “offshore-ing” of jobs and relocation of industry to countries with lower standards and production costs.

U.S. Southeast State GHG Emissions, 2005

The U.S. Southeast is a major contributor to global warming--if the Southeast were its own country, it would be the sixth largest emitter of greenhouse gases (GHGs) in the world. The most recent estimates for total GHG emissions for select Southeast states are presented in this table.

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.
