A complete review of market drivers, trends and competitor types in the energy efficiency and green buildings segments of the climate change industry. CCBJ's $56 billion U.S. energy efficiency market in 2013 includes $47.5 billion in equipment, devices, appliances and systems and $8.8 billion in specialty services for EE, smart grid and demand response. Recent annual growth in these EE&DR segments has been relatively modest, and aggregate annual growth of about 4% is forecast. CCBJ estimates the green buildings market at $76 billion in 2013, so together the two segments made up $124 billion or 43% of the $287 billion U.S. climate change industry in 2012. Pursuing these markets-and the larger opportunities worldwide-is a diffuse collection of manufacturers, service providers, engineers, consultants, financial institutions, system integrators, contractors and other solutions providers profiled and interviewed in this special edition of CCBJ.
