Renewable energy is the largest sustainability sector by funding volume, most public-sector climate spend flows here, directly (CfD auctions, IRA tax credits, EU Innovation Fund) or indirectly (grid, storage, transmission). For founders, the non-dilutive opportunities cluster in earlier-stage tech (next-gen PV, floating offshore, enhanced geothermal, perovskites) and in deployment-support for harder-to-finance projects. Listed below are the open renewable energy grant calls in that landscape, taken from each funder's own notice and re-checked on every refresh.
Energy grants divide into two families that rarely share a form. Deployment pots such as the EU Innovation Fund, the US Department of Energy and the UK Net Zero Innovation Portfolio back kit that already works, usually at 30 to 50 per cent intervention rates against matched private capital. Earlier research calls, Horizon Europe and ARPA-E and Innovate UK among them, fund lower technology readiness at far smaller cheques. Applying to the wrong family is the most common reason a strong project scores badly.
This page lists open renewable energy grants currently tracked by Raise Lens — 1,206 of them right now, sorted with the soonest deadline first. Every listing has been classified against the sustainability taxonomy rather than matched on keywords, so what appears here is renewable energy work rather than anything whose description happens to mention it.
The funders publishing renewable energy grants here include Instituto para la Diversificación y Ahorro de la Energía (IDAE), Enova, Sustainable Energy Authority of Ireland (SEAI), among 2 others. Who is funding matters as much as what: eligibility, reporting burden and the realistic timeline to a decision vary far more between funders than between individual calls.
Geographic coverage on this page spans MENA, SE-ASIA, AFRICA, GLOBAL, GLOBAL-SOUTH. Eligibility is usually tied to where the work happens or where the applying organisation is registered, and the two are not always the same — worth checking before investing time in an application.
