Ninja Logo

Renewables.ninja allows you to run simulations of the hourly power output from wind and solar power plants located anywhere in the world. We have built this tool to help make scientific-quality weather and energy data available to a wider community.

Team

The Renewables.ninja is a collaboration between Stefan Pfenninger and Iain Staffell, who both research the effects of integrating renewable technologies into our energy systems.

Stefan is the project lead, designing the solar power model and masterminding the web application. He is a postdoc at ETH Zürich.

Iain designed the wind power model and provides assistance in developing the web application. He is a lecturer in sustainable energy at Imperial College London.

Data sources

The ninja works by taking weather data from global reanalysis models and satellite observations. Our two data sources are:

Solar irradiance data is converted into power output using the GSEE model (Global Solar Energy Estimator) written by Stefan Pfenninger [1]. Wind speeds are converted into power output using the VWF model (Virtual Wind Farm) written by Iain Staffell [2].
