1. National Policies
(1) Ministry of Economy, Trade and Industry
@Introduction of solar photo voltatic generation (PV) and electric cars (EV) reduces CO2 exhaustion. The government starts to establish a system. In this system the government considers the above reduction to be equivalent with the other CO2 reduction. The government gathers these accumulated CO2 reduction as allowed exhaustion (CAP) and it can be dealt with other CO2 sources like in its own factories. The to make new CO2 reduction system. The ministry demands 89 billion yen for subsidy to promote introduction@and it is by about 30% increase. If this budget is approved, about 170 thousands sets of solar photo-generation and about 30 thousands EV would be introduced. It was estimated that about 1 ton of CO2 is reduced annually at each home. If above total 2 million sets are fully operated annually, 200,000 ton or more exhaustion can be gathered. If the government can gather these allowances and buy it to energy industry, material industry etc., companies can buy this in the framework to achieve the target of Kyoto Protocol (to the UN Framework Convention on Climate Change). The price of the above reduction is dependent on market price. Recently it is 1,000 - 2,000 yen / ton. If the homes, which introduce solar photo-generation and EV, will use them for 10 years, total 4 billion yen could be sold to industries. This profit is paid to the government. The subsidy for average solar photo-generation system is 2 - 2.5 million yen / set and that of EV is 1,14 million yen / set and 3.8 million yen. Hot water suppliers of high efficiency are also objects of subsidy. Applications from homes are needed. [The Nihon Keizai Shimbun Sept.7, 2010]

@The above 3 companies, Toyota Motor Corp., Hitachi Corp. and Panasonic Electric Industry Co., Ltd. start demonstration of smart grid in Rokkasho village, Aomori prefecture in this week with a major wind generation company. Electric transmission lines, detached houses (2 houses by each company) etc. were newly built, and they are going to develop technology to use 100 % natural energy efficiently. The demonstration is going to be done by 2012, for about 2 years.
@The 3 companies, Toyota, Panasonic Denko and Japan Wind, completed 2 houses each in the village, and some devises are installed in thee "smart house". Engineers etc. lived in the houses and repeated charge and discharge into cars and batteries to find points to be improved. In Toyota houses PHEV, which can be really charged and discharged by home power sources. To operate batteries installed in cars as general use batteries, an energy system will work. In some of smart houses, solar cell panels and small wind mills are set. By using .multiple sources, tasks to use these multiple sources are examined. Hitachi will install in all houses "smart meters" to send information of generated power and consumed power to the control center. The information is used to study a devise to reduce the consumption. The power sources used are wind mills of Japan Wind in Rokkasho village and 100 kW solar panels built by Hitachi. The center controls the generating power, watching demand data. Using batteries attached generating devises, they would establish technology to control wind energy.
@The transmission lines used in this demonstration was wired by Japan Wind. Power failure can be happened artificially, so that tests, which are difficult in an experimental room,. can be done to get data for technological improvement of the other companies. The demonstration is carried out without governmental support but with funds by the participating companies. Companies hurry technology development in environment close to real life. For instance, Toyota joined this program in this viewpoint.
