Abstract—This study reviews technologies of new and renewable energy applicable to roads as part of the effort to reduce emissions of carbon dioxide which is causing global warming and to secure sources of alternative energy. It was found that solar light energy and small wind power energy are most appropriate for roads whose main functions focus on vehicle transport. The key for implementing solar light power generators and wind power generators are to secure maximum hours of sunlight and a consistent wind velocity throughout the year, respectively. The study estimated that solar light energy intensity is 578.2Wh/m²/d on an average daily basis and wind power intensity at 5.53kWh/d on an average daily basis for 1kW wind power generator by considering capability of energy generators for the two renewable energy types and the climate conditions of Korea.

Index Terms—Energy intensity, new and renewable energy, solar energy, wind power energy.
