This　paper　reviews　the　history　of　renewable　energy　development　in　the　BRICS　countries.　The　financing　models　for　renewable　energy　development　of　BRICS　countries　include　bank　financing,　institutional　loans,　industry　funds,　and　international　financing.　This　paper　identified　several　problems　with　financing　in　BRICS　countries,　including　a　lack　of　financing　channels,　investment　shortage　for　small　and　medium-sized　enterprises　and　imperfect　government　policies.　The　solutions　to　these　problems　include　expanded　capital　markets,　the　financing　of　leasing　services,　and　build-operate-transfer　and　build-own-operate　projects;　further,　a　financial　citizen　participation　model　should　be　employed　similar　to　that　as　Germany　and　European　Union　emissions　trading　system　(EU　ETS).　A　financial　citizen　participation　model　means　that　legal　entities,　private　individuals,　and　agricultural　enterprises　invest　in　renewable　energy　infrastructure　through　equity.　A　regional　reserve　ratio　monetary　policy　is　suggested　to　allow　regions　to　develop　renewable　energy.
