You don't use os.Getenv to set a variable but to get a value of the variable. Use os.Setenv to set a variable like that:

package main
import (
        "fmt"
        "os"
)
func main() {
        os.Setenv("VAR", "10")
        fmt.Println("value of VAR:", os.Getenv("VAR"))
}

Also notice that retrieving value of an environment variable that has been set in the same program doesn't make sense - they are usually used to pass environment to child processes.
