The Maryland Energy Administration (MEA) provides rebates for the installation of residential and non-residential wind energy systems through the Windswept program, which is part of the Clean Energy Grant Program. Systems of up to 750 kilowatts (kW) are eligible for the program. The incentive level is set at $3,000 per kW of normalized generating capacity at a reference wind speed of 11 meters per second (m/s). Incentives are allocated on a per property basis, meaning that incentives will not be awarded for multiple turbines on the same property.

This statute exempts from the state sales tax all wood or "refuse-derived" fuel used for heating purposes. The law does not make any distinctions about whether the qualified fuels are used for residential or commercial heating so both purposes should qualify. As of October 2012 the Maryland sales tax rate is 6%.

The state of Maryland permits local governments (Md Code: Property Tax § 9-242) to offer property tax credits for high performance buildings if they choose to do so. In October 2010 Anne Arundel exercised this option by enacting legislation (County Bill 78-10) providing a property tax credit for high performance dwellings built on or after July 1, 2010 that meet or exceed USGBC LEED Silver standards. The credit was amended in 2012 (County Bill 03-12) to add the National Green Building Standard (NGBS) as an eligible green building certification system for the tax credit.

Anne Arundel County offers a one-time credit from county property taxes on residential dwellings that use solar and geothermal energy equipment for heating and cooling, and solar energy equipment for water heating and electricity generation. Photovoltaic (PV) systems and geothermal systems were initially not eligible for the tax credit, but PV systems were added by legislation enacted in January 2009 (County Bill 81-08) and geothermal heating and cooling systems were added in April 2010 (County Bill 17-10).

'' Note: The federal government has imposed and updated appliance efficiency standards through several legislative acts,* and now has standards in place or under development for 30 classes of products. In general, states which had set standards prior to federal action may enforce their own standards until the federal standards take effect. States that had not set standards prior to federal action must use the federal standards.

The state of Maryland permits local governments (Md Code: Property Tax § 9-242) to offer property tax credits for high performance buildings if they choose to do so. Baltimore County exercised this option in 2006 by creating property tax credits for new and existing multi-family residential (50+ units) and commercial buildings that meet certain high performance building standards.

The total volume of credits awarded through this program has exceeded the budgeted dollar amount. There is now a wait list for new credits. The wait for applications not yet received is expected to last until at least July 2015.

Baltimore Gas and Electric (BGE) provides incentives for technical assistance, retrofitting inefficient equipment, starting a new construction project, launching a major renovation, purchasing new equipment, or replacing equipment at the end of its lifespan. Incentives typically cover up to 50% of the total cost for retrofit projects and up to 75% of the incremental cost for new construction projects. The customer chooses their own contractor or service provider.
