RECOGNISING OUTSTANDING ACHIEVEMENTS IN ENERGY

The Global Energy Prize annually honors outstanding achievements in energy research and technology from around the world that are helping address the world’s various and pressing energy challenges.

World Environmental Forum: Contributing to the Global Environment through Innovation in Technology

The Global Energy Prize laureate, Shuji Nakamura, participated in ASAHI World Environmental Forum-2015 that was held in Tokyo for the 8th time. He held a Special Talk “Contributing to the Global Environment through Innovation in Technology.”

Professor Nakamura, who has been awarded the Global Energy Prize for the invention, commercialization and development of energy-efficient white LED lighting technology, presented his vision on how innovation in technology can contribute to the efforts to address environmental issues.

As a reminder, the Global Energy Prize is awarded for outstanding scientific research and technological development in energy. The main prerequisite is that they must help increase the effectiveness and ecological security of the Earth's energy sources in the interests of humanity.

Shuji Nakamura’s invention (blue light emitting diode) has opened new approaches to obtaining pure white color and was a necessary precondition for the further invention of environmentally friendly light sources. This innovation has also lead to the ability to save energy and reduce carbon emissions. The efficiency of a white LED is 5 times the one of a fluorescent lamp and 20 times the one of a traditional incandescent bulb. According to DOE reports, transition to LED-based lighting will allow 300 TW•h savings and reduce annual CO2 emissions by 210 million metric tons only in the USA.

Speaking about his invention, Professor Nakamura underlines: “At the end of the day, it is important for me to know that I have in some way contributed to improving the lives of others. It is rewarding to see just how far the invention of the blue LED has gone to aid people in reducing their electrical energy consumption thereby indirectly reducing our contribution to climate change.”
