What Template

I think you mean theme, and I don’t know if you can base it on thematic, but I would search further, or maybe make your own theme.

how can i know what kind of plugins they used on that site myenergyprofile.com

Go back to the site and look at the source code in your browser -or- their plugin directory is quite browsable. You can see them all right from the directory.

//myenergyprofile.com/wp-content/plugins/
