Aiming to Promote Renewable Energy

Promoting and expanding the use of renewable energy

The SoftBank Group

The devastation caused by the Great East Japan Earthquake and the incident at Tokyo Electric Power's Fukushima Daiichi Nuclear Power Plant has stimulated interest in energy demand and power-saving programs in Japan and has had a profound effect on the lives of people, not only in East Japan, but throughout the entire country. The SoftBank Group recognizes the energy issue as a challenge that concerns the whole of Japan and believes that the promotion and expansion of safe and renewable energy is one of the solutions.

In July 2011, the SoftBank Group, together with local governments, established the Renewable Energy Governors' Alliance at the prefecture level and the Renewable Energy Governors' Alliance for Designated Cities at the urban level and began serving as secretariat for these two alliances. Through the alliances, together with 36 prefectures throughout Japan and the local governments of 18 cities, the SoftBank Group shares policy recommendations and information to promote the spread of renewable energy.

Construction of mega solar power plants and wind farms throughout Japan

SB Energy Corp.

SB Energy aims to promote and drive the adoption of renewable energy, such as large-scale solar power generation (mega solar) and wind power generation, by using land owned by public bodies and private owners throughout Japan to build and operate renewable energy power plants.

Starting with the mega solar power plants in Kyoto and Shinto, Gunma Prefecture, which went online on July 1, 2012, SB Energy operates mega solar power plants in 16 locations throughout Japan (19 power plants) as of July 3, 2015, and is taking steps to start up more. Moreover, the company has installed 29 wind turbines at its first wind farm, Wind Farm Hamada, which is scheduled to go online during fiscal 2015. When operational, the facility is expected to have an output of around 48.0 MW and generate around 85 million kWh annually. SB Energy will continue to promote the construction of mega solar power plants and wind farms throughout Japan.

Weed Removal Trials with Sheep and Goats

At SoftBank Tottori Yonago Solar Park, we carried out a trial using sheep and goats to remove weeds as part of our activities that show consideration for the environment. The trial took place in autumn of 2014, and proved effective in removing weeds and attracting visitors. There was also a therapeutic effect for local residents and people working at the site. In 2015, we started a second trial from April, when the weeds began to grow. Throughout the growing period, we will compare against mechanical weed removal in terms of efficacy, quality and safety of the weed removal on target areas, as well as the therapeutic effect and other factors.

Future × Energy Project: an experience-based program designed to teach elementary-school children about the environment

SB Energy Corp., EDUAS Corp.

In the future, as we promote the wider use of renewable energy, it will be important to continually raise the level of awareness of energy issues among all Japanese people. As one way to achieve this, SB Energy, together with EDUAS, Kyoiku K.K. and Tankyusha K.K., are running the “Future × Energy Project”, an experience-based program for elementary-school children. The objective of the program is to give children the opportunity to think about the environment in a proactive and creative manner.

In the program, children use iPads and other devices. Through a series of workbooks, video content, and other educational materials, as well as group projects, they learn and experience the existence of energy in the world around them, how to use energy in everyday life, and how to use sources of energy found in the natural world. The program has received accolades for how it provides learning that brings out the children's motivation and creativity. In February 2013, the program won the Incentive Award in the Companies Collaborating with Local Communities Education Category at the 3rd Annual Career Education Awards sponsored by Japan's Ministry of Economy, Trade and Industry.
