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.

​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

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.

Energy Efficiency in Indian Sugar Industries

The energy audits conducted by The Energy and
Resources Institute (TERI) in various sugar industries
in India indicates that many sugar plants are still using
out-dated technology and inefficient equipment, and
are following inefficient operating practices. But some
of the progressive sugar plants have already initiated
various energy efficiency measures and are reaping
the benefits of reduced energy consumption.
This article depicts a comparison of specific energy
consumption of inefficient sugar plants and energyefficient

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

| 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.
