With the passage of The American Recovery and Reinvestment Tax Act of 2009, Congress modified and expanded the scope of many of the energy efficiency and renewable energy tax incentives. The legislation includes several provisions relating to these incentives, most notably extending the consumer incentives through 2010 and increasing the cap on efficiency incentives from $500 to $1,500 per household. Additionally, there are several new incentives for plug-in electric vehicles. An overview of the legislative changes and details on the individual measures can be found on the Tax Incentives Assistance Project (TIAP) Web site.
