Repository of problems worth solving
World Solve is a public institutional repository for identifying real unresolved problems across science, society, health, governance, economics, and local systems. Each entry is intended to be citable, inspectable, and actionable.
Publicly citable
Every problem has a stable citation code for reference and discussion.
Filtered by relevance
Search by category, geography, status, and keywords.
Builder-oriented
Use the repository to find startup ideas, policy leads, and research agendas.

Training today's largest AI models can consume as much electricity as thousands of homes use in a year. Without more efficient methods, AI's environmental cost will keep climbing alongside its capabilities.

Fusion promises nearly limitless clean energy, but every experiment so far has needed more power to run than it generates. Cracking this would end the global energy crisis outright.

Achieving biotechnologies for engineering crops that require substantially less water and fertilizer at meaningful scale demands simultaneous progress in fundamental research, engineering integration and socio-technical systems that work for low- and middle-income settings. Existing efforts remain fragmented relative to the magnitude of the challenge.

Despite recognition of its importance, reliable methods for architectural and planning approaches that make cities more walkable and less car-dependent are still lacking. Progress is hindered by incomplete mechanistic knowledge, high capital and operational barriers, and the absence of deployment models suited to the contexts of greatest need.
