Contribute to better environment, reliable energy supplies as “A Corporate Citizen of Planet Earth” We aim to support safe, secure, richer lifestyles for people worldwide

Toshiba will promote the following measures in energy production.

Measures ofToshiba energyvision Promote nuclear power and establish FBR & the nuclear fuel cycle.

Zero CO2 emissions by performance improvements in thermal power systems, e.g. CCS* *Carbon Capture & Storage Zero power loss by superconductivity transmission & stable dispersed energy supply by microgrid

Promote commercialization of dispersed power and renewable energy systems

Reduce CO2 emissions by promoting Converve uranium resources by reprocessing high reliability LWR nuclear fuel Light Water Reactor (LWR) FBR Volume of CO2 reduction per unit: 6.7m tons/year & hydropower

Thermal Reduce CO2 emissions by improving Achieve zero CO2 emissions by combining performance of thermal power plants Carbon Capture & Storage and advanced Advanced Combined Cycle Ultra Supercritical (USC) ultra supercritical turbines Advanced Ultra Super Critical (A-USC) Volume of CO2 reduction Volume of CO2 reduction per unit: 0.13m tons/year per unit: 0.32m tons/year Volume of CO2 reduction per unit: 5m tons/year Transmission & distribution

Reduce CO2 emissions by reducing loss in Microgrid, new concept power supply; electric transmission at ultra high voltage Reduce environmental loads by Ultra High Voltage (UHV) superconductive transmission Volume of CO2 reduction per unit: 7 tons/year Micro-grid New energy Reduce CO2 emissions with renewable Reduce CO2 emission by residential fuel cell geothermal and wind power generation co-generation Geothermal power Wind power Residential fuel cells
