The alternative energy format, An appropriate format
The purpose of this study is to survey these natural energy resources such as Water Energy, Wind Energy and Solar Energy in each area of Chiang Rai and to find the suitable format of manufacturing electric current from natural energy area in Chiang Rai. The survey consists of acquiring natural energy in each area of Chiang Rai using a surveying tool as Flow water Meter, a Digital Anemometer, and Digital Light Meter. Wind energy uses 5 times measurement among 4 directions, north, south, east and west direction which 6 time ranges are verified from 08.00 a.m., 10.00 a.m., 12.00 a.m., 2.00 p.m., 4.00 p.m., and 6.00 p.m. after that the maximum value /day, minimum value / day, and total average values are calculated. Water energy with 5 times measurement are verified from 08.00 a.m. , 10.00 a.m. , 12.00 a.m. , 2.00 p.m. , 4.00 p.m. , and 6.00 p.m. after that the maximum value /day, minimum value / day, total average values and using surveyed depth of water. Solar energy as well as ranging 5 times measurement during 08.00 a.m. , 10.00 a.m. , 12.00 a.m. , 2.00 p.m. , 4.00 p.m. , 6.00 p.m. then the maximum value /day, minimum value / day, and total average value are calculated. Result of surveying the natural energy resources in Chiang Rai during August - October 2008 was Test Value of Wind Energy = 5 m/s,[11]for electric current can be generated in 6 sub districts in Tung Kor, Wiang Chiang Saen, Wiang Nuea, Ban Du Sub District Municipality, Pong Noi, and Mae Suai Sub District Municipality. Test Value of Solar Energy = 50,000 LUX,[11]for electric current can be generated in 13 sub districts, Chok Chai, Tung Kor, Nang Lae, Pa Ngae, Pa Tan, Pong Pa, Mae Kham, Wiang Nuea, Pong Noi, Mae Sai Sub District Municipality Wiang Ka Long Sub District Municipality, Muang Phan Sub District Municipality and Mae Suai Sub District Municipality. Test Value of Water Energy = 13 m/s,[11]for electric current can be generated in 2 Sub Districts, Wiang Chiang Saen and Chok Chai. Result of surveying the format for natural energy resources, Wind energy, Solar energy and Water energy within 18 area in Chiang Rai indicated an appropriate value of Wind energy with Test Value = 5 m/s for electric current generator for 6 sub districts could be generated but 12 areas could not be generated. Solar energy for electric current generator in 13 Sub Districts could be generated with available Test Value = 50,000 LUX but 5 Sub Districts could not be generated. Water energy for electric current generator 2 Sub Districts could be generated but 16 Sub Districts could not be generated with available Test Value = 13 m/s.
