This tool provides very detailed cost estimates for a variety of clean energy technologies in the United States. It covers generation, fuel, and vehicle technologies. Estimates presented include capital costs, feedstock costs, levelized cost of energy, and levelized cost of fuel. The tool also presents cost projections to 2050 for power generation and vehicles. Policymakers can use this model as a template for developing baseline cost analyses in their country, or, if such data exists in their country, for purposes of comparison.
