I would definitely not use Economic Explained as an intro to economics, EE in reality is on the lower end of quality for pop-economics related content.

A better alternative is something like Marginal Revolution University which create videos on Economic theory, applications, etc. These videos are created by actual professional economists who are active in publishing. Plus, it delves in to the actual theory itself, which EE doesn't really do.
I especially recommend MRU's Mastering Econometrics series which feature Joshua Angrist (Nobel Prize Winning Economist) explaining Econometrics (a challenging field) in a fun and comprehensive way that most can just pick up and understand.

Alternatively, picking up an introductory Microeconomics or Macroeconomics textbook is reliable too, even if less engaging.
