“Ameresco achieved strong second quarter results as we continued to execute our strategic plans,” stated George P.

With today’s economic climate, higher energy costs and budgetary constraints, as well as aging infrastructure requiring non-discretionary upgrades, Ameresco’s comprehensive energy efficiency and renewable energy solutions offer budget-neutral, environmentally-friendly, bottom-line results for customers.”
