Hot countries are more eco friendly than colder ones
As someone who grew up in the mediterranean, we have oil heating (ie the most expensive type) for winter and we have air con in summer when it's cold. We also have water shortages aplenty and we have to think of ingenious ways to get rid of rubbish generally, because if left out in the sun it stinks to high heaven.
What's different between hot and cold climes is that while we have central heating and aircon, we NEVER use it ALL the time. We only put aircon on if it's above 35 outside or during a heatwave, otherwise simply closing the shutters and keeping the house dark is a remarkably efficient way of keeping a house cool in summer. Opening the windows wide open is possibly the worst thing you can do to keep cool. Similarly in winter, we don't need the central heating on at all. Just a few short bursts (2 hours between 6 and 8pm for example) is plenty heat for the entire night. Needless to say if you have the aircon on while in bed, you're pretty stupid as you'll wake up with a chill, and if you have your heating on while asleep too, your duvet isn't good enough or, quite frankly, you're not heating yourself up making passionate love. Yes, sex is a pretty good way of keeping warm!
Rubbish in hot countries has to be picked up within a day before it gasses the street. Seriously perishable stuff is usually biodegradable anyway, and mincing it up and putting it down the drain is a better bet (provided your drains can handle it). Then what's left is plastics, glass, paper and aluminium, which surprisingly is all recyclable and doesn't stink.
Furthermore, when I explained to my (English) girlfriend that there was a water shortage one summer, she balked at the fact I left the bathwater in the bath and scooped it up and threw it down the toilet instead of using the normal flusher. Old soapy bathwater is perfectly good enough to flush away last night's curry (and the soap helps ward off the nasty niff emitting skid marks left in the old bowl).
Finally practically everyone over there knows that heating stuff up is the most expensive thing to do. So the amount of crap that resides on top of an oven (because everyone cooks real mediterranean food needing HOURS of cooking) is amazing - kettles, hot water bottles, coils for outside hosepipes linked to the outdoor shower and so forth. Last but not least the ubiquitous solar panels to heat up water is almost everywhere.
The point of it all, is just using PLAIN OLD COMMON SENSE and a little bit of LATERAL thinking pays a huge dividends - that's why my typical energy bills come in on average at on average, one sixth of mates' bills, and I wouldn't particularly call myself eco-conscious at all (I certainly don't bother unplugging my stuff, and I like my light!).
