       The well-known drawbacks  imposed by lock-based synchronization
       have  forced   researchers  to  devise   new  alternatives  for
       concurrent  execution,  of  which  transactional  memory  is  a
       promising  one.  Extensive research  has  been  carried out  on
       Software Transaction Memory (STM),  most of all concentrated on
       program performance, leaving  unattended other metrics of great
       importance  like  energy consumption.   This  paper presents  a
       systematic  methodology to  characterize a  class of  STMs that
       implement a  common set of  API calls.  We  thoroughly evaluate
       the impact on energy consumption  due to STM by quantifying the
       energy  costs  of  the  primitives involved  in  an  optimistic
       time-based  STM implementation.   This  work is  a first  study
       towards  a  better  understanding  of  the  energy  consumption
       behavior  of STM  systems, and  could prompt  STM  designers to
       research new optimizations in this  area, paving the way for an
       energy-aware transactional memory.
