Submission + - Could a Power Efficient Console Make a Real Difference to Energy Use? (arstechnica.com)
Fluffeh writes: "Environmental groups often push for efficiency improvements in big energy hogs like cars and appliances. It's viewed as a major way to reduce our collective energy use and carbon footprint. But a recent study argues a simple firmware update for current high definition video game consoles could provide a much easier way to chop off a small but significant portion of US residential energy usage. The study, published by a team of Carnegie Mellon researchers in the latest issue of the journal Energy Efficiency, estimates that 100 million video game consoles sucked up nearly 16 terawatt-hours (TWh) of energy a year in the US in 2010. That's roughly one percent of the total household energy consumption for the entire country, and nearly twice as much as all the electricity used by all homes in the state of Rhode Island."
