Cogeneration projects generate heat and electricity simultaneously from the efficient use of fossil or biomass fuel. In some cases, waste heat is used to generate cooling via a vapor absorption chiller (trigeneration).

Bioenergy projects create electricity from growing and combusting biological materials. This replaces fossil fuels, such as coal and fuel oil, and prevents carbon dioxide emissions.

Microcredit projects create partnerships with microfinance institutions to finance and distribute household clean energy products. These products prevent use of wood, coal, and fuel oil.

Waste gas recovery projects flare or vent into the atmosphere low quality natural gas extracted with oil in order to reduce its harmful methane content. Such gas streams can instead be recovered and, after proper conditioning, utilized in generators to produce heat and/or electricity.
