To demonstrate how significant energy efficiency is to better environmental performance, Figure 5 compares internal temperature and power consumption of two JVC video cameras (the current TK-C9200UA and an older TK-C920U) at an ambient temperature of 35°C. The graph expresses this information in terms of product longevity and CO2 emissions.
