The National Association of Energy Service Companies (NAESCO) celebrates 32 years of advancing the energy efficiency industry. NAESCO is the leading national trade organization representing and promoting the energy efficiency industry in the energy marketplace, the media, and the government both at the state and federal level. NAESCO's active membership consists of key energy efficiency industry leaders representing ESCOs, energy efficiency and energy equipment manufacturers, suppliers, and subcontractors. NAESCO also welcomes as members engineers, consultants, financial/legal/insurance providers, government agencies, and thought leaders from the energy NGO and academic communities.

Energy Service Companies contract with private and public sector energy users to provide cost-effective energy efficiency retrofits across a wide spectrum of client facilities, from college campuses to water treatment plants. Effectively utilizing a performance-based contract business model, ESCOs have implemented significant comprehensive energy efficiency retrofit projects over the last three decades. The latest Lawrence Berkeley National Laboratory report estimates that ESCO investment in energy efficiency retrofit projects currently runs about $5 billion a year. Since 1990, ESCOs have delivered:

$45B in projects
$50B savings – guaranteed and verified
425,000 person-years of direct employment
$30 billion of infrastructure improvements
470 million tons of CO2 savings at no additional cost
