E-ON, a company in the United Kingdom company, hosts five simple games to help people learn about energy.  The main page is called Energy Home.  You can access all five activities from there.

I have separate links to each of the five games on my English For Beginners page at the bottom of the Non-Fiction category.

They have text, audio support, and good visuals and are accessible to High Beginning English Language Learners.

I learned about this site from Teachers First, which has a nice collection of learning resources.
