Increasing the energy efficiency is not exactly a lavish gift. Maybe some materialls that went into the project were even manufactured/provided by "you". Somehow you see your neighbour a "foreigner" that eats your dinner and steals your money! You are not a nice guy. Without cooperation you can't acomplish much as an individal human being nor as an individual country(bigger or smaller). Maybe your neighbour is already helping you with cheaper food or whatever he is producing since his energy bill is now lower.
