| 2018

​We evaluate the accuracy of the satellite-based surface solar radiation dataset called Surface Solar Radiation Data Set-Heliosat (SARAH-E) against in situ measurements over a variety of sites

in India between 1999 and 2014. We primarily evaluate the daily means of surface solar radiation. The results indicate that SARAH-E consistently overestimates surface solar radiation, with a mean

​Solar microgrids in rural India: Consumers' willingness to pay for attributes of electricity​

Graber Sachiko, Narayanana Tara, Alfaro Jose, Palit Debajit
| 2018

This paper assesses consumer valuation of different attributes of electricity supply to elucidate the conflict between solar microgrids and the centralized utility grid in India, as well as to provide insight into supporting government policies and structures. The study contributes significantly to the understanding of the role of microgrids in complementing a centralized system and its value as a sustainable energy solution for development.

Government of India had proposed to deployment of 40,000 MW of grid-connected rooftop solar power projects by the year 2021-22 under the National Solar Mission. Detailed review of various policy and guidelines developed for two major schemes such as off-grid and on-grid connected systems revealed that utility companies offered different types of cost effective tariff to facilitate quick start-up, implementation and encourage participation from stakeholders.

​The influence of polarized electrodes on the methane production, which depends on the sludge concentration,

was investigated in upflow anaerobic bioelectrochemical (UABE) reactor. When the polarized

electrode was placed in the bottom zone with a high sludge concentration, the methane production was

5.34 L/L.d, which was 53% higher than upflow anaerobic sludge blanket (UASB) reactor. However, the

methane production was reduced to 4.34 L/L.d by placing the electrode in the upper zone of the UABE

Harmful algal blooms (HABs) are increasingly attracting attention all over the world. A diverse set of algal species including diatoms, flagellates, chrysophytes and dinoflagellates can cause harmful blooms, and many produce toxins that harm other organisms and human health. Intensive cyanobacterial blooms, in particular, have been associated with high costs for society due to their potential toxicity. Algal blooms can produce different toxins. These toxins present a long-standing threat to human and environmental health.

| 2018

Construction sector accounts for about 25% of the carbon emissions in India. With constant increase in the rate of construction, it is important that the sector identifies and applies sustainable construction and production practices. The sustainability index (SI) of building materials created as part of the study in the Himalayan region of South Asia will help create low-cost, climate resilient structures based on local climate and available resources. This implies customization as per regional needs when scaling up in other topographies.

Use of renewable energy to enhance sustainability of the mid-day meal program in schools

| 2013

Children in government schools in Karnataka, India are provided cooked mid-day meals under the 'Akshara Dasoha' scheme. The aim of this initiative is to provide a nutritious meal to school children (who mostly hail from the lower economic strata) to enhance their nutritional status and as an incentive to minimize dropouts. However, cooking these meals have numerous bottlenecks including irregular supply of cooking fuel i.e.

Trend analysis and ARIMA modelling of pre-monsoon rainfall data for western India

| 2013

Spatial and temporal variability of rainfall over different seasons influence physical, social and economic parameters. Pre-monsoon (March, April and May - MAM) rainfall over the country is highly variable. Since heat lows and convective rainfall in MAM have an impact on the intensity of the ensuing monsoons, hence the pre-monsoon period was chosen for the study. The pre-whitened Mann Kendall test was used to explore presence of rainfall trend during MAM. The results indicate presence of significant (at 10% level) increasing trend in two stations (Ajmer, Bikaner).
