The document summarizes the first Quadrennial Technology Review (QTR) conducted by the US Department of Energy. The QTR aims to define a framework for energy technologies, explain DOE's roles in energy transformation, and establish priorities. It outlines six technology strategies to address challenges of energy security, environmental impacts, and competitiveness. The QTR conducted technology assessments and established a balanced portfolio across timescales, energy challenges, and strategies. Future QTRs will provide more detailed reports, and a future Quadrennial Energy Review may coordinate a federal energy policy.
