In recent years, crowdsourcing, which involves recruiting members of the public to help collect data, has been tremendously helpful to provide researchers with unique and rich datasets, while also engaging the public in the process of scientific discovery. In a new study, an international team of researchers explored how crowdsourcing projects can make the most effective use of volunteer contributions.

Despite successes in reducing poverty globally in the last two decades, almost one billion people are still living without access to reliable and affordable electricity, which in turn negatively affects health and welfare, and impedes sustainable development.
