Transparent Cost Database


The Transparent Cost Database collects program cost and performance estimates for energy efficiency and renewable energy technologies in a public forum where they can be viewed and compared to other published estimates.

For emerging energy technologies, a variety of cost and performance numbers are cited in presentations and reports for present-day characteristics and potential improvements. Amid a variety of sources and methods for these data, the US Department of Energy, Office of Energy Efficiency and Renewable Energy’s technology development programs determine estimates for use in program planning.

The database includes literature on technology cost and performance estimates (both current and future projections) for:

  • vehicles
  • biofuels
  • electricity generation

All data are downloadable for full transparency. Levelized cost calculation parameters for all three areas can be adjusted and the dynamic results can be downloaded in CSV or as a formatted spreadsheet.
