Sony reduces the power consumption of individual products by setting specific annual targets for each product category. Regulations governing the energy efficiency of products are being enforced in countries all over the world. For example, from 2010, the subsequent enforcement of various product categories began in the European Union through the Energy-related Products Directive (ErP), legislation which, in addition to electrical products, covers windows, insulation materials and other energy-related products, demanding compliance with environmental legislation across a broad range of products. Electrical products, in particular, must comply with strict energy-reduction standards. Sony products comply with energy efficiency regulations in every country where they are enforced. In countries where no regulations exist, Sony has established product-specific energy reduction targets and is active in achieving these targets.

The BRAVIA™ HX750 Series of LCD televisions, launched in 2012, realize low energy consumption and sharp contrast with deep blacks by precise control of the LED backlight and panel. While achieving superb picture quality such as 4-times speed play, it delivers high energy efficiency. In particular, KDL-55HX750 achieves the lowest energy consumption of 132 kWh/year (based on Japan's Law Concerning the Rational Use of Energy) the highest achievement made by any Sony televisions with the screen sizes of 55V and 52V to date. The KDL-55HX750 also qualified for European Union energy efficiency class A+ rating and satisfied the International ENERGY STAR® program's requirements for televisions (Version 5.3), earning it the ENERGY STAR Most Efficient 2012 designation.

The most appropriate picture quality depends on what you are watching, whether it is sports, musical performances, or other programming. The ideal level of backlighting also varies. That is why the BRAVIA™ HX750/850 series of LCD televisions, launched in 2012, automatically switch to the optimal level of backlighting to suit the type of program being watched. This careful control of backlighting per program can reduce power consumption by up to 30%*1 while ensuring maximum picture quality.

For televisions marketed in North America, Sony is actively promoting to meet the requirements of the International ENERGY STAR® program. 20 models (approx. 77%) models launched in the United States and Canada in 2012 *2 complied with the International ENERGY STAR® program requirements (Version 5.3), while 100% of models achieved the program's sleep mode power consumption requirements by a margin of 50% or more.

Sony is working to reduce the amount of energy consumed by the Blu-ray Disc™ players it markets around the world. The BDP-S185 Blu-ray Disc™/DVD player, launched in the European and North American markets in summer 2011, was designed from the ground up with the aim of realizing a Blu-ray Disc™/DVD capable of delivering a video, audio and environmental performance overwhelmingly superior to that of units offered by Sony's competitors. At the heart of the player is newly developed integrated circuitry. Two microcontrollers, considered standard, were consolidated into one; components were integrated on a single board; and the number of memory chips was reduced from four to two. These technologies have combined to substantially reduce overall energy requirements. The BDP-S185 consumes a mere 10 W when in operation, approximately 55% less than its immediate predecessor, the BDP-S370, for example, and is approximately 30% smaller, which contributes to the reduction of CO2 emissions during transport.

Discovered by NASA, magnetic fluid is a liquid that can be attracted by a magnetic field. With the aim of achieving a significant improvement in speaker efficiency, Sony has promoted R&D with the aim of realizing a magnetic fluid suspension suitable as an alternative to conventional damper suspensions. Sony conducted extensive tests to determine the optimal magnetic strength and viscosity for passively damping the high-speed vibration of the voice coil, and in 2012, it succeeded in developing a speaker with a magnetic fluid suspension for mass production. Thanks to the absence of dampers, which generate secondary sound pressure causing sound distortion, this speaker consumes approximately 35% less power at +2dB noise level than conventional speakers,* producing crystal-clear sound quality. Sony's magnetic fluid speakers are used in the CMT-V70B Walkman® component stereo, sold primarily in Japan, as well as in the BDV-N790W 3D Blu-ray Home Theater System for overseas markets.

The VAIO® Z Series, launched in 2012, realizes both low power consumption and high performance by fully leveraging the latest technologies.

For example, VAIO® Z Series computers feature low-power dual-channel solid state drives, making them perfect for long use without plugging in, such as during long meetings or travelling. Power consumption is reduced at all times, including when booted. These computers also sense the level of ambient light and automatically adjust the brightness of the LCD display accordingly, further reducing energy consumption.

Sony is actively promoting to meet the requirements of the International ENERGY STAR® program for personal computers, with 100% of new models (14 series) launched in fiscal year 2011 complying with the program's Version 5.2 requirements, which came into effect in July 2009. As a result, 100% of new models released after July 2009 are Version 5.2 compliant. Of those models, 6 series (approximately 42%) exceeded the Version 5.2 requirements by a margin of 50% or more in TEC (Total Energy Consumption) value.

In addition, all new AC adapters sold from fiscal year 2009 have achieved Level V rating described in International Efficiency Marking Protocol for External Power Supplies.

Environmental information, including power consumption and ENERGY STAR®-qualified products, is available for each model on the VAIO® websites for Europe and Japan.
