A sampling of these project models include: energy efficiency (from large industrial facilities to individual houses), heating and cooling (e.g., biomass, heat pumps, and solar air/water heating), power (including renewables like solar, wind, wave, hydro, geothermal, etc. but also conventional technologies such as gas/steam turbines and reciprocating engines), and combined heat and power (or cogeneration).
Sampuli ya modeli za mradi inajumuisha: ufanisi nguvu (kutoka vifaa vikubwahadi nyumba za watu binafsi), kupasha joto na kupoza, (kwa mfano,mkusanyiko wa viumbe hai, pampu za joto, na upashaji joto kwa kutumia mionzi ya jua/upashaji maji) nguvu (ikijumuisha vifaa vya kufanywa upya, upepo, mawimbi, haidrona n.k. lakini vile vile teknolojia za kawaida kama vile tabo za gesi/mvuke na injini zinazo rudishiana), najoto na nguvu zinazotumika pamoja (au uzalishaji nguvu pamoja)
