In the Implementation of any electrical power generation project, the basic requirement is the total electrical energy demand estimation. In order to estimate the total electrical energy demand, various methods can be used but neither of those methods can give the exact demand. Therefore approximate analysis of energy demand is always taken in to the consideration. In this study three villages are selected in Rajasthan state and electrical energy demand of those villages is estimated. For the estimation of energy demands two sources of data are taken in to consideration. i.e. survey data and bill data. Survey data is collected by a quessionaire based survey and bill data are taken from electricity Distribution Company for the three selected village. On the basis of these two data, energy consumption parameters such as Energy consumption of village in MWh/annum, Energy consumption of family in kWh/annum, Per capita Energy consumption in kWh/annum, Energy consumption o MWh/month, Energy consumption of family in kWh/month, Per capita Energy consumption in kWh/month and Average Power in kW/month are calculated for each village .these energy consumption parameters are calculated in both the cases i.e. by using survey data and by using bill data, and comparison has made in tabular manner as well as graphical manner in order to observe deviation between the parameters properly. 1. INTRODUCTION Jhar, Mansarkheri and Khijooriya jatan selected villages for the study which are located in @ IJTSRD |

Cement production is synonymous to green house emissions and mineral resource depletion. So as to produce about 1tonne of cement, 1.5 tonne is required and nearly 1tonne green house gases are emitted out. This article present sustainable use of calcium meta silicate mineral "wollastonite" (CaSio3) as a partial replacement of cement. Six concrete mixes were prepared by replacing cement with wollastonite (0-25%). Test result showed that 10% wollastonite can effectively replace cement with improvement in strength and durability parameters. Incorporation of wollastonite in cement production will help in sustainable development of country.
