saving energy should be good for both environment and money I know that. but lights of my school 's toilet automatically turned off every 10 seconds and toilet sheets are cold (Japanese ones are usually heated) . even hand dryers are switched off. if we cannot use it's better to not to install.
since beginning of this week we don't need to wear my necktie and no need my jacket either. supposed to save energy and environment. however we have to set the temperature of an air conditioner 28 Celsius. that hot.
