For some building to upgrade them i need energy but how i do get it D:?

Do you mean electricity? If so then you can build power plants from the "road" icon in your build menu. It should be in the bottom left corner of the "road" build options. Also, if u need don't need more electricity and just mo electricity coverage, just build a electric substation, which is right next to the power plant building option.
