About the Cover

The present investigation on energy consumption pattern and roof top solar power potential was conducted in Solan city of Himachal Pradesh, India. Four sectors namely residential, institutional, industrial and commercial were selected. It was found that the maximum monthly overall electricity consumption was 352.22 kWh. The overall number of LPG cylinders used in domestic sector during summer was 1.34 and in winter it was 3.69. The average electricity consumption during summer and winter seasons in case of hospital was 647.50 and 662.30 MWh, respectively, in case of bank it was 136.29 and 182.62 MWh, respectively, for private and government schools it was 525 MWh and 385 MWh, respectively. The overall LPG consumption in intuitional sector was 3.25 and 7.75 cylinders for summer and winter, respectively. The monthly electricity consumption in small and micro industries for summer was 2,419 MWh and 2,156 kWh, respectively and for winters it was 2,610 MWh and 5,120 kWh, respectively. The annual energy consumption and carbon dioxide emission of Solan city was hence calculated to be 287.17GWh and 0.55 million tonnes, respectively. The annual rooftop solar power potential of Solan city was worked out to be312.08GWh. It showed that solar power if used judiciously in Solan city, it would be sufficient to fulfill the energy needs of the city and also to curb carbon dioxide emission in the city due to usage of non renewable energy resources.

PHYSICS

Description of motion of system of particles in different resisting media

Alalibo T Ngiangia, Eqhuanoye S Ikata, Peter O Nwabuzor

A numerical study of the description of motion of system of particles in different resisting media was carried out. The paper transforms the time dependent Newton’s equation of motion in a resisting medium into a space dependent form which necessitated the use of classical Runge-Kutta method of order four to determine the solution of the model.
