Please don't ask your people not to use airconditioning during summer. This is not a good idea because Taiwan is at the altitude that hot can kill people. Ask people to use energy saving LED lightbulb is okay. Ask them to use energy saving appliances like airconditioning units that save energy is okay. But don't ever tell people not to use airconditioning because once if anyone die of overheat, they will blame you.
In fact, you should subsidize poor people some energy discount programs. It is part of social justice.
