The data are mostly taken from the Santa-Fe Performance Curve DataBase. The database has been constructed from personal communications and from Colpier and Cornland (2002), Goldemberg et al. (2004), Lieberman (1984), Lipman and Sperling (1999), Zhao (1999), McDonald and Schrattenholzer (2001), Neij et al. (2003), Moore (2006), Nemet (2006), Schilling and Esmundo (2009). The data on photovoltaic prices has been collected from public releases of Strategies Unlimited, Navigant and SPV Market Research. The data on nuclear energy is from Koomey and Hultman (2007) and Cooper (2009). The DNA sequencing data is from Wetterstrand (2015) (cost per human-size genome), and for each year the last available month (September for 2001-2002 and October afterwards) was taken and corrected for inflation using the US GDP deflator.

How we process data at Our World in Data

All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.

At the link below you can find a detailed description of the structure of our data pipeline, including links to all the code used to prepare data across Our World in Data.

Notes on our processing step for this indicator
  • Photovoltaic cost and capacity data between 1975 and 2003 has been taken from Nemet (2009). Prices from Nemet (2009) have been converted to 2022 US$ using: https://www.usinflationcalculator.com/
  • Photovoltaic cost data between 2004 and 2009 has been taken from Farmer & Lafond (2016). Prices from Farmer & Lafond (2016) have been converted to 2022 US$ using: https://www.usinflationcalculator.com/
  • Photovoltaic capacity data between 2004 and 2022 has been taken from IRENA.
  • Photovoltaic cost data between 2010 and 2022 has been taken from IRENA.
