Energy Sources - Simple EFL / ESL reading comprehension

This is a short text that includes 3 types of renewable and non renewable energy sources, briefly stating their main characteristics. It also includes a set of comprehension questions in the back. It was originally designed to be implemented during a RUNNING READING activity, where students work in pairs: one goes to the text (posted somewhere around the room) and reads it, and later runs back to their partner to complete the comprehension questions.
