Turkey is the one of the countries in the world which has potential of renewable energy resource because of its geographical position. However, being usage of renewable energy resources and applications (RERAs) is low, it shows that awareness and consciousness of RERAs is very low too. Education must play a key role in growing out of an energy culture at a nationwide scale, which means developing an energy awareness of environmental, scientifically and economical respects. Energy awareness is a concept that includes multiple aspects and this situation closely related to sustainable development. In this study high school students' awareness of RERAs has been investigated and data was obtained from interview forms of 127 students who have been attending different high school in Isparta city. As the results of this study it has been found out that high school students' awareness of RERAs is very low, they have lots of misconceptions about RERAs, they mostly wouldn't have a career plan about RERAs and they mostly are not aware of research centre about RERAs at the university, which is in the city they live. High school students being keen on arranging field trip to research centre related to RERAs at the university give us signs about renewable energy education.
