This research aimed to transfer technology about biogas digester construction and applying the biogas in household to teachers and students in Suksasongkhro Tak school. They were instructed and trained about biogas digester construction and applying the biogas produced from animal manure on cooking in household to reduce using LPG. The research operations were separated to 4 phases. The first was preparation and making understanding. The second was instruction and practical training. The third was monitoring and project evaluation. The last one was organizing the science project event. The number of participant teachers and students was 330. From the result of 5 scale questionnaire in project evaluation it was found that the evaluation about knowledge and understanding showed the maximum scale ( = 4.42 SD = 0.84). The second was about location duration and food ( = 4.36 SD = 0.75). The evaluation about the knowledge showed the lowest scale ( = 4.28 SD = 0.77). For the project evaluation of success it was found that every biogas digester done by participants could produce the biogas and it could be use to replace LPG and reduce expenditure about 1400 – 1500 baht/month. The total construction cost of biogas production system was 58000 baht. So the payback period was 3.22 years.

The objective of this paper was study guidelines for taxation to promote the use of energy efficient passenger cars. The passenger car taxation of 4 developed countries; namely Japan Germany United Kingdom (UK) and United States (US) were analyzed and compared with Thai taxation. And studied barriers for promote the use of energy efficient passenger cars in Thailand. This survey conducted by using the close-ended questionnaires collecting data from 400 people who used passenger cars in Bangkok. The results found that tax on acquisition in the developed countries were only subjected to sales tax while Thailand’s acquisition tax composed of customs duty excise duty municipal tax and value added tax. The ownership tax rates of passenger cars in Japan Germany and UK were based on different fuel consumption parameters such as cylinder capacity vehicle weight and CO2 emissions which can promote energy efficient cars. On the contrary the ownership tax rate of USA and Thailand reduces with the age of vehicle. Fuel tax was imposed to support the country energy policy. Opinion survey results of barriers for promoting energy efficient passenger cars in Thailand showed that the significant problems were the lack of incentives measures to promote the use of energy efficient cars.
