SAMPLING Sampling is the act‚ process‚ or technique of selecting a suitable sample‚ or a representative part of a population for the purpose of determining parameters or characteristics of the whole population. REASONS FOR SAMPLING There are six main reasons for sampling instead of doing a census. These are; * Economy * Timeliness * The large size of many populations * Inaccessibility of some of the population * Destructiveness of the observation * Accuracy or Reliability

rural electrification needs which remain unfulfilled which were discussed in chapter 1 previously‚ through incorporating market mechanisms to create viable and sustainable business models to propagate solar decentralized solutions towards providing grid quality electricity. The significant nature of both the unelectrified and underelectrified portions of the rural population remain an impediment to growth and inadvertently suppresses their energy demand‚ which thereby stunts their quality of life

the power plant. Going off the grid with solar Solar Barn: Going off grid is a huge advantage of solar power for people in isolated locations. Solar energy can be produced on or off the grid. On grid means a house remains connected to the state electricity grid. Off grid has no connection to the electricity grid‚ so the house‚ business or whatever being powered is relying solely on the solar or solar-hybrid. The ability to produce electricity off the grid is a major advantage of solar energy

BASIC MAP READING Introduction Maps and their substitutes are of particular value to the military establishment. It is frequently necessary to identify ridges‚ valleys routes of movement‚ and other characteristics of a section of terrain that cannot be reconnoiter in advance. Plans for the future operations must be based on knowledge gained in part from maps their substitutes. Therefore‚ as future member of the AFP‚ you must know how to use and read a map. It is mandatory for you to know

Introduction India’s energy sector is currently confronted with multiple challenges‚ which stem not only from supply-side constraints but also from demand pressures imposed by a buoyant economy and a growing population. As per recent Planning Commission estimates‚ if economic growth is sustained in the 7-8 per cent range‚ the energy demand would rise by at least 5.2 per cent annually. In the face of relatively inflexible supply options‚ the gap between energy requirement and availability
