Abstract: Vietnam has been regarded as a country with immense opportunities for renewable energy in general and for the development of solar and wind power in particular. Existing policy targets and mechanisms have been taken into practice with an aim to encourage this promising field and increase the proportion of electricity generated from these two power sources. However, the potential of these technologies has yet to be fully utilized, with approximately seven percentage of the nation’s energy mix coming from renewable energy sources, according to Vietnam Electricity annual report. Conventional energy sources (coal, natural gas, and hydropower) still play a significant role in Vietnam’s total primary energy supply. In this research, evaluation of the potential of renewable energy sources, emphasizing on solar power energy with its opportunities and challenges in Vietnam’s power energy sector will be discussed. The main idea of this paper is to provide an overview of methodologies used for assessing photovoltaic potential and estimation of energy production from a given photovoltaic installation site. This can be a recommendation information of input indicators for investors, planners, and developers to strategize further decisions for the expansion of renewable power energy sources, especially photovoltaic systems in the chosen region.

Abstract: Municipal solid waste is a pool of various solid wastes by towns and cities from different types of household activities. All over the world, municipal solid wastes are dumped in permitted landfills. Landfill gas is a mixture of methane and carbon dioxide which is emitted from the dumping sites of municipal wastes. Methane is a flammable toxic greenhouse gas more damaging to the climate than carbon dioxide. Instead of discharging into the atmosphere and becoming a greenhouse gas which is harmful to the environment, methane can be collected in every landfill and used to produce useful energy. This paper outlines the basic procedure for estimation of methane from landfill site. The Landfill Gas Emissions Model (Landgem) is an automated estimation tool with a Microsoft Excel interface which is available from the EPA's Clean Air Technology Center. It can be used to estimate emissions rate of methane from municipal solid waste landfills. Based on the methane emission rate obtained from Landgem output and the heating value of methane, the net heat input available and hence the potential for generation of electric power can be computed. A typical case study on the evaluation of methane emission rate from a landfill site at Namibia and its potential for generation of electric power as well as the cost estimates are presented. It is found that the power plant would be able to provide 142 streetlights in the city with electrical energy every day.
