Over the past ten years, the various benefits renewable energy (RE) technologies have increasingly captivated the interest of the international community. Understanding the availability and accessibility of renewable energy resources is crucial for the usage of the technologies that harness them. This course takes participants through different renewable energy resources (sun, wind, and water) and focuses on existing commercially viable renewable energy technologies. Their suitability for different situations and in different parts of the world is evaluated. With this course, learners are introduced to different measures for integrating RE electricity sources into the grid. For the first time this year, this course will incorporate an introduction to hydrogen session, focused on hydrogen as an emerging energy technology.
