Why Renewable Energy

Biomass, or renewable energy from waste such as forest debris, agricultural waste and scrap lumber, is quickly gaining popularity as an addition to many renewable portfolio standards (RPS) across the United States. Ameresco helps customers and communities harness the potential of biomass energy by building power and cogeneration facilities that cleanly burn renewable waste to fuel specialized engines that generate power and heat.

Solar energy is the technology used to harness the sun's energy and make it useable. As of 2011, the technology produces less than one tenth of one percent of global energy demand. However Solar energy is the cleanest and most abundant renewable energy source available. Solar technologies can harness this energy for a variety of uses, including generating electricity, providing light or a comfortable interior environment, and heating water for domestic, commercial, or industrial use.

In recent years, the proliferation of wind power has been driven by national and international legislation, technological advancements and the continuing push for a clean energy economy. Wind is a clean source of renewable energy that produces no air or water pollution, and many governments offer tax incentives to spur wind-energy development.

Hydroelectric power, electricity produced from generators driven by turbines that convert the potential energy of falling or fast-flowing water into mechanical energy.
