This tailored technical assistance includes:

  • Establishing baseline energy use
  • Measuring available renewable resources
  • Assessing the viability of various energy technology solutions
  • Identifying opportunities to improve building and transportation energy efficiency
  • Evaluating potential sites for renewable energy projects.

Island Project Examples

NREL's comprehensive integrated deployment model has been applied in island projects such as Hawaii and the U.S. Virgin Islands (USVI).


The state of Hawai'i launched the Hawaii Clean Energy Initiative (HCEI) in 2008 to address extremely high energy costs resulting from its heavy dependence on imported fossil fuels. The HCEI goal is to meet 70% of Hawaii's energy needs with energy efficiency and renewable energy by 2030. In partnership with the state of Hawaii, the U.S. Department of Energy, and various government and private groups, NREL provides on-the-ground technical assistance and training aimed at increasing Hawaii's energy security and building a clean energy economy.

U.S. Virgin Islands

In support of the Energy Development in Island Nations initiative, NREL is helping the USVI government and utility develop and implement a road map for reducing the territory's dependence on fossil fuels 60% by 2025. The USVI is 100% dependent on imported fossil fuels to meet its energy needs, and its energy costs are more than four times the U.S. average. With technical assistance from NREL, the USVI is working to comprehensively address a variety of technical, policy, financial, and cultural challenges in order to achieve its clean energy goals.
