About this sector

Renewable energy funding covers solar, wind, hydropower, geothermal and bioenergy, from early research to grid-scale deployment. Public money tends to back demonstration, grid connection and access to energy in emerging markets, while procurement notices buy installation, operation and maintenance. Calls often ask for proof of resource assessment, permitting progress and local partners.
