On May 9, the Americans for a Clean Energy Grid released its report The Net Benefits of Increased Wind Power in PJM. The report found that doubling wind energy production in the North American grid could result in $6.9 billion in annual savings by 2026 as well as a reduction of carbon dioxide emissions from the baseline by 14 percent. The report, which was prepared by Synapse Energy Economics, analyzed work by PJM Interconnection. It found that every dollar of investment in the grid in the Mid-Atlantic region resulted in $2 of savings.
