Comparison with Competing Energy Sources Sample Clauses
Comparison with Competing Energy Sources. The alternative energy sources for water heating applications in Vietnam are mainly electricity, Liquefied Petroleum Gas (LPG), Kerosene, Biomass and Fuel Oil. During the last 10 years, electricity tariffs were increased by about 8%. On the other front, though the use of solar energy for water heating applications requires comparatively high initial investments but the system once installed will be operational for about 20-30 years with marginal maintenance activities.
Comparison with Competing Energy Sources. The alternative energy sources for water heating applications in Thailand are mainly electricity, Liquefied Petroleum Gas (LPG) and Fuel Oil. During the last 10 years, the percentage increases in the prices are 5%, 10% and 12% for electricity, LPG and Fuel Oil respectively. On the other front, the use of solar energy for water heating applications requires comparatively high initial investments but the system once installed will be operational for about 20 years with marginal maintenance activities. The financial viability of solar water heating systems over other sources of energy is illustrated below. The payback periods are longer when SWH systems are to substitute electricity in residential applications and fuel oil in commercial and industrial applications compared to that of electricity use in the commercial sector.
