In conjunction with the release of the annual Wind Technologies Market Report, prepared for the US Department of Energy, Berkeley Lab has produced a series of interactive data tools that allow users to explore the data from the report.
To prepare the report, Berkeley Lab researchers compile the most comprehensive set of data on performance, cost and prices, market growth, and technology trends for wind projects, at both the project and state level.
The interactive visualizations provide access to the data, allowing the user to easily focus on specific geographic areas, time periods, or attributes of wind energy deployment in the United States. Users can apply filters to show subsets of data, zoom in on regions, and see project level information by mousing-over a point. No programming or spreadsheet skills are required.
The visualizations cover:
A set of maps that show the growth of wind power by state over time, showing the annual and cumulative capacity installed, plus the percent of in-state generation.
Maps that show the 2017 capacity factors for 825 projects built between 1998 and 2016, by project and by state averages. Project locations are overlaid on a map of wind resources from the National Renewable Energy Lab.
A bubble chart that shows power purchase agreement (PPA) prices since 1996 for over 430 projects, color-coded by region.
Maps that show how generator size, hub height, rotor diameter, and specific power vary by location and over time.
A dashboard that explains the importance of specific power, which is the relationship between the output of the generator and the size of the rotor.
The visualizations are posted here, along with the full report, a presentation slide deck that summarizes the report, and an Excel workbook that contains data from the report. The visualizations are public domain, and can be embedded in articles and blog posts.
Additional visualizations are available for the 2016 Utility-Scale Solar report, which tracks progress for solar power projects greater than one megawatt in size. They will be updated in September 2018, when the 2017 edition of the report is released.
Berkeley Lab’s contributions to the report were funded by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy.
