Use of Renewable Energy

Toshiba Group is continuously striving to use renewable energy for a wider range of its operations. In FY2010, the Group used 29,249 MWh's worth of renewable energy. Toshiba Television Central Europe switched to purchasing electricity supplied by hydroelectric power plants. Toshiba Corp. has used a green power system since January 2005 and has since been purchasing two million kWh of electricity under a green power certificate annually.

Toshiba Television Central Europe (Poland) reduced CO2 emissions by 1,850 tons annually by switching to electricity from hydroelectric power plants, a form of renewable energy, and optimizing power system operation.

Switching to renewable energy sources for all purchased electricity

Toshiba Television Central Europe, headquartered in Poland, is one of Toshiba Group's major production sites making LCD TVs for the European market.

1.Choosing renewable energy

The Polish government's energy policy aims to shift 15% of the country's energy to renewable sources by FY2020 and 20% by FY2030.
In January 2011, in accordance with this policy, Toshiba Television Central Europe switched its electricity purchasing from thermal power plants to hydroelectric power plants ahead of all other companies. Now, all of the electricity it purchases comes from renewable sources.
The Polish manufacturer purchases approximately three million kWh per hour annually, resulting in a reduction in CO2 emissions of approximately 1,850 tons per year. The company has cut back CO2 emissions by approximately 70% compared to FY2009, when its plants emitted a total of 2,712 tons, including gas.

2.Optimization of power system operation

In FY2010, Toshiba Television Central Europe controlled and optimized the operation of the power system at its plants more carefully than in the previous year, mainly by reviewing the operating hours of compressors and ventilation systems. By doing so, the company reduced power consumption by 7% and CO2 emissions by 168 tons annually.

Case Studies in FY2008

Case Study 1: Outside Advertisement and bulletin board powered by Solar Energy

As part of long-term efforts to mitigate climate change, the local subsidiary in Malaysia has started installing solar power generation equipment in its several facilities, focusing attention on the effective use of the same. The power demand for the external advertisement board and the environmental section bulletin board has been provided by this equipment.

Case Study 2: Installation of Photovoltaic and Wind-power Generation Systems

At Yokkaichi Operations of Toshiba Corp., photovoltaic and wind-power generation systems, when operating at full capacity, generate enough electricity for 100 fluorescent lamps. The panel shows how electricity is generated and data, such as the amount of electricity generated and the reduction in CO2 emissions, in order to highlight the advantages of renewable energy.
