Energy Efficiency grants — page 6

Programmes for industrial efficiency, building retrofits, heat recovery and demand reduction. Typical funders are UK DESNZ and the Industrial Energy Transformation Fund, the US DOE, EU LIFE and Horizon, and utility efficiency-obligation schemes. Listed below are the open energy efficiency 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 energy efficiency grants currently tracked by Raise Lens — 629 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 energy efficiency work rather than anything whose description happens to mention it.
The funders publishing energy efficiency grants here include SUSI Partners AG, Ghana Climate Innovation Center, Joules Accelerator, 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 SE-ASIA, EUROPE, GLOBAL, AFRICA, MENA. 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.
