From Japan:

"As of January 2008, 11 citizens' wind turbines were in operation in Japan. The first wind power plant built with citizen funding, known as Hamakaze-chan, or "beach wind," with a rated output of 990 kilowatts (kW), was installed in Hamatonbetsu in Hokkaido, northern Japan, in September 2001. Since then, citizen-funded wind turbines have become popular not only in Hokkaido but also in the prefectures of Aomori, Akita, Chiba, and Ibaraki. The total output of these 11 wind turbines has reached 15,790 kW, and their annual power generation is roughly 40 million kWh, enough to serve the equivalent of 10,700 households, and estimated to reduce carbon dioxide (CO2) emissions by about 24,000 tons.

Japan has developed some of the most cutting-edge solar power technology in the world. It is also ranked among the best in terms of photovoltaic panel production. At the same time, however, Germany and other countries have surpassed its installed capacity of solar power systems. Germany, for instance, has promoted solar power largely due to its feed-in tariff (FIT) systems, but Japan has not yet established a market for it because it hasn't prepared a similar system. Moreover, it abolished the subsidy for households. These are the main two reasons solar power systems have not become more common in Japan, even though Japan has the technology and production capacity.

In order to change society at the local level, the phenomenon of citizens jointly planning and funding power plants is expected to play more of a role in expanding renewable energy use by strengthening people's willingness to support such projects and contribute funds. Building a system to promote new energy resources should be actively pursued in order to realize a low-carbon society." (

"The main organization that helped with the installation of Hamakaze-chan was a nonprofit organization (NPO) called the Hokkaido Green Fund (HGF). Since 1999, the HGF has been working on the now-successful green electricity rates system, in which members pay an additional 5% of their monthly electricity bill to build a green fund. The green funds accumulated are then used to cover the installation cost of citizen-funded renewable energy power plants. In addition, the HGF established a system in which people other than NPO members and electricity customers of Hokkaido Electric Power Co. can donate money.

NGO Wins New Energy Award for Citizen-Funded Wind Power Plants

The total project cost of Hamakaze-chan was about 0.2 billion yen (about U.S.$1.9 million). About 80% of that was paid with funds invested by citizens, rather than donations. The HGF expanded the system by establishing a company called the Japan Green Fund Co., in February 2003, allowing citizens from any part of Japan to invest.

Japan Green Fund For Renewable Energy Established


The company is fully funded by an intermediate corporation, the Japan Green Fund. Two NPOs that were involved with establishing the corporation were the HGF and the Institute for Sustainable Energy Policies (ISEP), which provides resources and services to realize sustainable energy policies. The directors consist of representatives from citizen-funded renewable energy projects in different parts of Japan. The corporation built both a nationwide network and a system for monitoring the use of citizens' funds.

Institute for Sustainable Energy Policies


The most recently built wind power plant, Kanami-chan (1,650-kW), which means "wind wave," started operation in the city of Ishikari in Hokkaido in January 2008. A total of 470 shares were offered at 500,000 yen (about $4,762) per share, which amounted to 235 million yen ($2.24 million). As the total cost of the project came to 417 million yen ($3.97 million), the project was completed with a subsidy from the New Energy and Industrial Technology Development Organization (NEDO) for the promotion of local renewable energy in fiscal 2007.

Ohisama Energy Fund

An NPO named Minamishinshu Ohisama-Shinpo, or "Sun progress," has become a parent organization of the Ohisama Shinpo Energy Co., which was established in the city of Iida in Nagano Prefecture in December 2004 with the cooperation of ISEP. Ohisama Shinpo Energy aims to curb global warming and realize sustainable communities using local resources such as sunshine, heat, wind, forests, and other gifts from nature.

The company offered the Minamishinshu Ohisama Funds and received a full contribution of 201.5 million yen (about $1.92 million) from 460 people in May 2005. In addition to installing solar panels at 38 facilities, including kindergartens and community centers in the city of Iida, with a total generating capacity of 208 kW, the company promoted energy saving projects for public and private buildings. The total project cost of 360 million yen (about $3.43 million) was covered by the investments and a grant of 160 million yen (about $1.52 million) provided by the Ministry of the Environment, targeted for national projects that balance environmental protection and economic development. The company's dividend yield was just originally planned in June 2007.

One of the features of the fund is that it offers minimum investment amounts of as low as 100,000 yen (about $952) and 500,000 yen (about $4,762) per share. In November 2007, the Ohisama Energy Fund Co. was established, and it started soliciting for its investment fund, the Stop Global Warming Ohisama Fund, for a total investment of 462 million yen (about $4.4 million), and expanded the subjected area until the end of December 2008. As of November 7, it had already collected 337.8 million yen (about $3.22 million) in investments.

Citizen-Based Sustainable Energy Fund Launched to Stop Global Warming


The prefectures of Nagano and Okayama plan to introduce a total of 1,108 kW of solar power capacity in 110 places, and the combined area of solar panels in the two prefectures will be almost as large as a football field. They will also invest a total of about 1.73 billion yen (about $16.5 million) in energy saving projects, etc." (
