A current guide to REP eligibility, approved training, the 4-hour open-book exam, weighted renewable-energy topics, and calculator rules.
The REP credential is for professionals who specify, assess, justify, and manage renewable and alternative energy projects. Use this guide to align your application, training, study plan, and exam-day logistics with AEE requirements.
Use these points to prepare from the official REP exam structure instead of relying on broad renewable-energy review alone.
REP recognizes expertise in renewable and alternative energy technologies, project assessment, low-carbon goals, and sustainability strategy.
AEE lists routes through related degree plus experience, associate degree plus experience, ten years without a degree, or current CEM status.
International candidates who do not meet full eligibility may pursue REP-IT after approved training, application, and passing the REP exam.
The REP exam is a four-hour open-book exam based on 14 mandatory body-of-knowledge sections.
AEE says candidates must bring a hand-held calculator and may not use computers, tablets, or cell phones during the test.
Solar, wind, environmental impacts, hydropower, geothermal, financing, storage, building strategies, and biomass carry major weight.
REP candidates need more than technology definitions; they must assess feasibility, application fit, costs, incentives, storage, and sustainability goals.
Solar and wind are prominent, but hydropower, geothermal, environmental impacts, financing, storage, buildings, and biomass also need deliberate study time.
Open-book does not mean easy; organize formulas, technology comparisons, economic concepts, and key definitions so lookup time does not consume the exam.
Before scheduling, confirm training completion, application status, remote or in-person instructions, calculator rules, and any local partner requirements.

AEE's Certified Renewable Energy Professional credential recognizes professionals involved in specifying and applying renewable and alternative energy technologies, assessing renewable energy projects, and developing achievable low-carbon and sustainability goals. Eligibility routes include a related four-year degree, PE, or RA with two or more years of related experience; a two-year associate degree with five or more years; no degree with ten or more years; or current Certified Energy Manager status. International candidates who do not yet meet full eligibility may use the REP-IT route after training, application, and passing the REP exam.
The REP exam is a four-hour open-book exam with 14 mandatory body-of-knowledge sections. AEE's REP body of knowledge weights the largest areas around solar energy, wind energy, renewable energy and environmental impacts, hydropower, geothermal, financing and incentives, energy storage, building strategies, biomass, hybrid systems, waste-to-energy, hydrogen applications, transportation systems, and microgrid applications. Candidates must bring a hand-held calculator; AEE's study guide states that computers, tablets, and cell phones are not allowed during the test.
AEE describes the REP certification exam as a four-hour open-book exam.
The 14 sections include environmental impacts, solar, wind, hydropower, geothermal, biomass, waste-to-energy, hydrogen, hybrid systems, storage, building strategies, transportation, financing and incentives, and microgrid applications.
No. AEE states that candidates must bring a hand-held calculator and that computers, tablets, and cell phones are not allowed during the test.
REP is for professionals involved in renewable and alternative energy technologies, project assessment, system upgrades, energy storage, and low-carbon or sustainability goals.
AEE lists REP-IT for international candidates who do not yet meet full eligibility, after REP training, application, and passing the REP exam.
Match your degree, CEM status, and renewable-energy experience to AEE REP routes, or verify REP-IT if you are an international candidate.
Build a study matrix for environmental impacts, solar, wind, hydro, geothermal, biomass, waste-to-energy, hydrogen, hybrid systems, storage, buildings, transportation, financing, and microgrids.
Work cases that require selecting technologies, comparing resource fit, estimating economics, explaining incentives, and justifying renewable-energy investments.
Prepare an open-book reference system, verify hand-held calculator requirements, and remove any prohibited computer, tablet, or phone dependence.
Use the guide to self-serve, or talk to a coordinator if you need help mapping timelines, official requirements, or troubleshooting day-of logistics.
