You can have an impact on power consumption at a range of levels. From choosing appropriate algorithms, to switching to different data types, to changing compiler flags. Add together a few of these 'easy' 5-10% energy savings and you've just reduced your application's energy consumption by a third (OK, it's not quite that simple, but the principle stands).
