Conserving energy and using it more efficiently can significantly reduce greenhouse gas emissions. The U.S. is currently the world's largest consumer of energy. Conservation within the transportation, residential, commercial, and industrial sectors would have a tremendous impact on national and global emissions. For more information, visit the United States Energy Information Administration's website. For information on energy efficiency programs in New York State visit the NYSERDA website.
- Transportation: Since 1999, the transportation sector has led all U.S. sectors in emissions of CO2. Transportation sector emissions have increased approximately 26% since 1990.
- Residential: CO2 emissions from the residential sector include direct fuel consumption, such as the use of oil for heating and natural gas for cooking, as well as the use of electricity for cooling, lighting, and household electronic devices. Between 1990 and 2006, residential CO2 emissions grew by an average of 1.4% per year.
- Commercial: Commercial sector emissions include those due to energy use for lighting, space heating, and space cooling. Commercial sector emissions grew at an annual rate of 1.8% per year between 1990 and 2006.
- Industrial: Unlike the other sectors, industrial sector CO2 emissions have decreased in the U.S., largely due to downsizing of the older, coal-intensive industrial base. Between 1990 and 2006, total industrial coal use decreased by more than 27%.
- Agricultural: Best management practice (e.g., no-till) are effective ways to reduce greenhouse gas emissions.
