Study Debunks Six Myths About Electricity in the South
Research Suggests Clean Energy Can Help Meet Growing Demand
Posted December 1, 2011 | Atlanta, GA
Clean energy can help meet growing electricity demand and minimize pollution in the southern United States, but progress to adopt renewable energy strategies has been hindered by a number of myths, according to a new study by Georgia Tech and Duke University researchers.
The study, published in the journal Energy Policy, debunks popular myths about clean energy that have been promulgated by policymakers, business leaders and advocacy groups in the South. Those myths – encompassing both sides of the clean energy debate – may affect how the South responds to what is expected to be a 28 percent rise in population within the next 20 years.
“The South has an abundance of sustainable energy technologies and resources, but misperceptions about their availability and readiness result in support for conventional energy systems,” said Marilyn Brown, co-author and professor in Georgia Tech’s School of Public Policy. “Our research is motivated by the hope that promoting fact-informed dialogue can tackle such barriers and clear the way for a more sustainable energy future.”
Using an energy-economic modeling tool, researchers analyzed the following six myths, identified through their earlier research on energy in the South:
- Energy efficiency and renewable energy by themselves cannot meet the South’s growing electricity demand;
- The South does not have sufficient renewable energy resources to meet a Federal Renewable Energy Standard;
- Renewable energy cannot be promoted without escalating electricity rates;
- Energy efficiency and renewable energy policies are not compatible;
- Cost-effective energy efficiency and renewable energy policies are sufficient to retire existing coal plants and reduce air pollution;
- Power resource decisions have little impact on water resources.
The researchers found that energy efficiency and renewable energy can work together to meet projected growth without escalating electricity rates. The study also indicates that implementing renewable electricity standards and other complementary policies could stabilize greenhouse gas emissions. Coupling these policies with stronger regulations, such as a $15 per ton carbon tax, could help retire coal-fired power plants and reduce emissions by 23 percent compared to today’s levels. The researchers also found that while energy impact on water usage is largely ignored, renewable and efficient options could hold water-saving benefits—up to one trillion liters in 2030—for this drought-prone region.
“Myths about clean electricity shape perceptions and have delayed progress in the South,” said Etan Gumerman, the study’s co-author and senior policy analyst at Duke’s Nicholas Institute for Environmental Policy Solutions. “We hope that by casting doubt on these myths, we can begin a productive discussion about affordable clean electricity and how it could shape public policies.”
