Through the Energy Transition Initiative (ETI), the U.S. Department of Energy and its partners work with government entities and other stakeholders to establish a long-term energy vision and successfully implement energy efficiency and renewable energy solutions. ETI provides a proven framework and technical resources and tools to help islands, states, and cities transition to a clean energy economy and achieve their clean energy goals.

In 2008, the U.S. Department of Energy (DOE) partnered with the State of Hawaii to launch the Hawaii Clean Energy Initiative (HCEI). With its leading-edge vision to transition to a Hawaii-powered clean energy economy within a single generation, HCEI established the most aggressive clean energy goal in the nation. A decade after its launch, HCEI has significantly outdistanced its original goal of meeting 70% of Hawaii's energy needs through energy efficiency and renewable energy by 2030.

Through ongoing technical assistance, DOE, the National Renewable Energy Laboratory, and other key partners are sharing analytical and technical expertise in areas such as grid modernization and data visualization to inform Hawaii's path forward as it looks ahead to a new growth phase of integrating more advanced energy technologies and increasing the levels of variable renewable energy generation on its grid network. As Hawaii charts a new course toward a clean energy future, the lessons learned from its data-driven approach will help guide and inform other communities in advancing their energy transition initiatives. Read more about 10 years of progress toward advancing Hawaii’s clean energy goals in the Hawaii Clean Energy Initiative 2008–2018 brochure.

This action-oriented guide provides a readily available framework that any community can use to help successfully initiate, plan, and complete a transition to a clean energy system. Read lessons learned featured in the Playbook from island communities that have reached their goals by implementing renewable energy and energy efficiency technologies.

Get energy information about islands in the Caribbean, the Pacific, and the surrounding area, such as current electricity sector data, policies, and opportunities to reduce dependence on imported fossil fuels through energy efficiency and renewable energy.

Learn more about tools and tailored trainings that can help islands identify pathways and make decisions about their clean energy goals and projects. 

The ETI Energy Scenario Tool helps communities analyze different pathways to meet a given energy transition goal by modeling the levelized cost of electricity for custom, user-defined scenarios of supply and demand. Download the tool and user guide. For step-by-step instructions on how to use the tool, watch the video.

State and local governments can use this tool to get basic energy market information needed to plan and implement clean energy projects. Watch the video.
