Energy Needs and Sustainable Development of the World Heritage Site: A Proposition in Lumbini

Abstract

The energy need of people is growing worldwide and the same appears in Nepal. The energy sources apart from petroleum products are hydropower which is in majority and solar are also scattered for household consumption but the use of wind power from traditional methods is evident in the country which is distant from the use of turbines to harness the power of the wind. Focusing on heritage sites with potential such as Lumbini which is a world heritage site faces a lot of problems with energy need as the supply of hydropower and solar are not sufficient enough to fulfill the energy demand. Though the flow of wind is not consistent and high the alternative solution of a low speed wind turbine seems feasible through the preliminary study of wind pressure around the place as the average wind of the place around the year is 4m/s. The speed wind as low as 1.8 m/s could be harvested (Trongtorkarn, M.et.al 2017). The energy need and its sustainable attainability has implications on the involvement of the people for the wellbeing of heritage sites which can be a symbiotic relationship though it has to go through challenges. To reduce the energy demand in heritage areas, in this paper an hybrid solar-wind and hydro-oxygen model is developed. The proposed model is performed using thermodynamic analyses techniques. The result of the model shows, the proposed hybrid approach improves the energy sustainability in heritage areas.
