Abstract

Renewable energy is non fossil energy which can be renewed and managed properly. Therefore, the renewable energy resources would be sustainable. Those that can be classified as renewable energy are geothermal, hydro, solar, wind, biomass, ocean, fuel cell, and nuclear.

Abstract

This paper is to review existing knowledge on energy requirements for manufacturing photovoltaic (PV) module and system. Estimate energy (primary energy) requirements for manufacturing PV module for scenario: Low* and High1. For multi crystalline silicon (mc-Si)a. Low is 4200 MJ/ m2 (mc-Si) or 35 MJ/Wp = 3,395 kwh/Wpb. High is 11600 MJ/ m2 (mc-Si) or 96 MJ/Wp = 9.312 kwh/Wp2. For a single –crystalline (sc-S)a. Low is 6000 MJ/ m2 or 47 MJ/Wp = 4,559 kwh/Wp.b. High is 13900 MJ/ m2 or 109 MJ/Wp = 10.573 kwh/WpEstimate energy production (final yield) for application SHS (50 Wp) multi – crystalline (mc-S) is 65 kwh/Wp/year (1 Wp produce 1,3 kwh/year. Estimate Energy Pay-back Time ,” take energy to save energy”. for Solar Home System Application for over 20 year system life (under 1900 kwh/ m2/year irradiation) are 3-4 years for low scenario and 8 years for high.

Abstract

The most important part is manufacturing since PV modules areproduced under very height energy consumption characteristic.Photovoltaic energy production is suppose to be an environmentallyfriendly energy system with no emissions and no waste production, cleanand noiseless but ins important to ensure that manufacturing is not goingto be more harmful for the environment than operation advantages. Then itis very important to know if the product is going to be economically andenvironmentally viable for the overall life cycle. For the manufacturingprocesses environmental impact, three different studies have been carriedout: Energy Analysis, Energy Related Emissions Analysis and Materialflow analysis.Operation. Advocates of renewable solar system argue thatduring operation the environmental impact of this technology is minimal incomparison with other form of renewable energies. Decommissioning. At theend of the lifetime of the modules, they must be dispose in a sensitiveway. At the moment there are no many option for recycle the siliconwafer. Aluminum frames can be recycled separately in the same wayas this material normally is, glass could be recycle i technologies would exist to separates the glass from the adherent EVA and othermodule components.

Abstract

The renewable energy generally can support or trigger the economic growth in household utilization, and give rise to the opportunity for people (men or women) in rural areas to run small scale home industry. The introduction of renewable energy in rural areas will significantly transform the social, cultural and economic structure from traditional style to modern (western) one. The structural transformation will force all people to be drawn in. Many benefits can be gained if women participate in the transformation.This paper describes the impacts which will take place during the structural transformation in rural areas, in general, and women participation in particular. This will greatly determine the accomplishment in the policy and implementation of technology adaptation in renewable energy field.
