Being an agriculture rich state, Punjab has huge potential of biomass resource availability in the form of crop residues. Around 40.142Mty -1 of the total crop residue is generated from various major and minor crops, of which around 71% is consumed in various forms, resulting in 29% as a net surplus available for power generation. Basic surplus and net surplus crop residues for power generation potential were estimated in each district. Sangrur, Ferozpur, Amritsar, Patiala and Ludhiana are the major surplus biomass potential districts, while Rupnagar, Nawashahar, Hoshiarpur, Fatehgarh Sahib, Faridkot and Kapurthalla are least surplus biomass potential districts within the state. It has been estimated that around 1.510GW and 1.464GW of power in the state can be generated through basic surplus and net surplus biomass respectively. Besides, the seasonal availability, present usage pattern and costing of important crop residues are also estimated in each district of the state. © 2011 Elsevier Ltd. Source

South Asia accounts for 37% of the world's population without access to electricity. Such a situation continues to exist despite several initiatives and policies to support rural electrification efforts by the respective country governments including use of renewable energy technologies. While conventional grid extension has been the predominant mode of electrification in the region, the countries have also extensively used solar photovoltaic (PV) technology for energy access. However, there have been implementation challenges including technical, financial, institutional, and governance barriers. This paper, based on extensive literature review and survey of selected programs, shares the experience and lessons of solar PV programs for rural electrification in South Asia - both at the regional and country levels - and also presents a comparative analysis to exploit the cross learning potential. The paper suggests that output focused approaches, financial innovations, bundling of projects for concentrating energy loads, adopting standard processes and metrics, developing necessary infrastructure, and building local technical capacity are a key to enhancing the effectiveness of the solar PV programs. © 2013 International Energy Initiative.

INTRODUCTION: Air pollution concentrations in most of the megacities in India exceed the air quality guidelines recommended by the World Health Organization and may adversely affect human health in these cities. Particulate matter (PM) is the pollutant of concern in many Indian cities, particularly in the capital city of Delhi, In recent years, several actions have been taken to address the growing air pollution problem in Delhi and other Indian cities; however, few studies have been designed to assess the health effects of air pollution in Indian cities. To bridge the gap in scientific knowledge and add evidence to the ongoing studies in other Asian cities, a retrospective time-series study on air pollution and mortality in Delhi was initiated under the HEI Public Health and Air Pollution in Asia (PAPA) program. APPROACH: The study used retrospective time-series data of air quality and of naturally-occurring deaths recorded in Delhi to identify changes in the daily all-natural-cause mortality rate that could be attributed to changes in air quality. The 3-year study period included the years 2002 through 2004. The methodology involved: (1) collecting data on ambient air quality for major pollutants from all monitoring stations in Delhi; (2) collecting meteorologic data (temperature, humidity, and visibility); (3) collecting daily mortality records from the Registrar of Births and Deaths; (4) statistically analyzing the data using the common protocol for Indian PAPA studies, which included city-specific modifications. RESULTS AND IMPLICATIONS: The study findings showed that increased concentrations of PM with an aerodynamic diameter < or = 10 microg/m3 (PM10) and of nitrogen dioxide (NO2) were associated with increased all-natural-cause mortality. It was found that every 10-microg/m3 change in PM10 was associated with only a 0.15% increase in total all-natural-cause mortality. When NO2 alone was considered in the model, daily all-natural-cause mortality increased 0.84% for every 10-microg/m3 increase in NO2 concentration. No significant effect was observed for changes in sulfur dioxide (SO2) concentrations. The study provides insight into the link between air pollution and mortality in local populations and contributes information to the existing body of knowledge. Source

India generates over 370 million tonnes of biomass every year. In addition to the direct harvesting from plants, biomass is also produced as a by product in many agro based industries such as rice husk from rice mill, saw dust from saw mill, bagasse from sugar mills etc. It has been estimated that about 17 GW of power can be generated through cogeneration, combustion and gasification routes from the available biomass. However, for this potential to be realized, data on production, present usage patterns, prices and seasonal fluctuation on biomass is essentially required. The present article is based on the resource assessment of non-plantation surplus biomass with a view to using it for energy production and its utilization in the state of Haryana, India.Being an agricultural state, Haryana has a huge potential of biomass availability in the form of crop residue and saw dust. In the agricultural sector, a total 24.697Mty-1 of residue is generated, of which 71% is consumed in various domestic and commercial activities within the state. While in agro based industrial sector, a total of 646kty-1 of sawdust is generated, of which only 6.65% is consumed in the state. Of the total generated biomass in the state, 45.51% is calculated as basic surplus, 37.48% as productive surplus and 34.10% as net surplus. The power generation potential from all these three categories of surplus biomass is 1.499GW, 1.227GW and 1.120GW respectively. © 2010 Elsevier Ltd. Source
