1 Includes total capacity whose primary energy source is MSW. 
2 Agriculture byproducts/crops, sludge waste and other biomass solids, liquids and gases.  Does not include tires. 
3 Black liquor, and wood/woodwaste solids and liquids. 
MSW = Municipal Solid Waste.
PV = Photovoltaic.
Notes: Totals may not equal sum of components due to independent rounding. Data revisions are discussed in the Highlights section. Revisions to biomass capacity removed tires from renewable waste energy.
