With more than 200 sources of hot water at temperatures of 40-100 degrees centigrade, Vietnam has the potential to develop a strong geothermal energy system. At medium temperatures, geothermal energy can be used to dry products, as holistic care for the medical sector and similarly for tourism. However, geothermal energy development in Vietnam has remained largely untapped. Great potential Dr. Doan Van Tuyen from the Institute of Geological Sciences of the Vietnamese Academy of Science and Technology commented, "Compared with the rest of the world, Vietnam has medium potential for geothermal energy development. However, geothermal energy resources are available not just in one place, but throughout the country. Therefore, most localities can make use of this type of energy." Presently, there are more than 200 sources of hot water at temperatures of 40-100 degrees centigrade in Vietnam . Thermal reserves in the Red River Delta alone can be utilized to generate 1.16 percent of … [Read more...] about Geothermal energy development: untapped potential
A noted oceanographer says Vietnam is overlooking an abundant energy resource, the waves of the East Sea. Dr. Nguyen Tac An is former dean of the Vietnam Institute of Oceanography in Nha Trang and current Chairman of Vietnam's branch of the Intergovernmental Oceanographic Commission (IOC). An talked with the HCM City newspaper Thanh Nien about the potential for wave power development in Vietnam. In 1973, An says, research began on wave power in some developed countries like the US, Portugal and France. In 2003, Portugal deployed the first 30 MW wave power plant. The production cost of wave power is equivalent to wind power, that is, about 10 US cents per kilowatt-hour. What is wave power? Wave power is the capture of wave energy to do useful work, for example, electricity generation or water desalination. An easy way to capture the already abundant energy in the ocean is through a simple air chamber. As the waves rise and fall in the chamber, they force air … [Read more...] about Energy challenges: Why not wave power too?
A top rice producer like Vietnam also produces lots of rice husks. In the Mekong Delta, entrepreneurs are learning how to turn this 'waste' into electricity. In 2007, Vietnam produced nearly 36 million tons of rice, over half of it in the lush, sprawling Mekong Delta. It also 'produced' 7.5 million tons of rice husks. About half the volume of rice husks is used to feed cattle or make fertilizer or plywood. Some of it fuels brick kilns. However, about half is just wasted. The redundant rice husks are a headache for many rice millers because they have no place to put it. During the harvest seasons, some pay a lot of money to have the heaps of husks carried to rubbish dumps. Some just dump the rice husks into rivers (which is of course illegal). Not surprisingly, it has occurred to entrepreneurs and renewable energy experts that rice husks can be used to generate electricity. The experts say that 1.6-2.2kg of rice husk is enough to create 1kWh of power. Tran Quang Cu of the … [Read more...] about New energy for Vietnam: Producing power from rice husks
While the demand for energy is rising dramatically in Vietnam, development of renewable energy is still in its infancy and faces big obstacles. Investors dismayed as EVN turns its back on wind and solar power Wind power industry in Vietnam According to the Ministry of Planning and Investment, VietnamÃ¢ÂÂs demand for primary energy rose by 2.56 times from 1989 to 2008. Electricity demand rose 10.7 times. Virtually all was produced from traditional energy sources like coal, oil, natural gas and hydropower. Foreseeing a day when demand outstrips existing resources, the Government is turning its attention, at last, to renewable energy sources like wind and solar power, and to more efficient consumption, reports the HCM City journal Thanh Nien. "The state encourages the development and use of new and renewable energy resources through assisting projects to research, manufacturing and building models of new and renewable energies; exempting taxes for the import, manufacture and … [Read more...] about Renewable energy’s difficult birth
Norfolk Mansion, a property of serviced luxury apartments for lease, has implemented a number of plans and measures to go green and inspire its employees and guests to embrace its environmental conservation endeavor. Sven von Moock, general manager of Norfolk Mansion, recounts various initiatives and plans have been put in place to make guests and staff of the property in downtown HCMC aware about the importance of energy saving and environmental preservation. Sven von Moock of Norfolk Mansion stands by the solar absorption panels on the roof of the building in downtown HCMC - Photo: Mong Binh One of the many examples is Norfolk Mansion encourages its guests to reduce bed/bathroom linen washing but let them decide. The call has borne fruit as many guests have responded, … [Read more...] about Heating inspiration for energy saving
