The Importance of Health and Safety of Workers in the Energy Sector

By | | , ,
Leave a comment

With almost 250 fatalities in the oil industry for every one death of a worker in wind power, the renewable energy sector appears to be a much safer environment in which to work. Of course, the production of oil has a long established history and a much larger workforce; the International Labour Organisation estimates that at least 6 million people work directly for the industry. However as the renewable energy sector continues to grow, it may yet present some of the same health and safety risks as fossil fuel industries. And due to new hazards such as the extreme height of wind turbines, … Continue reading →

The world is currently facing an unprecedented health crisis, and as usual the vulnerable communities are hit the hardest.  Energy poverty (or lack of access to electricity) is worsening the humanitarian crisis amid COVID-19 pandemic, and is preventing the poor from securing social benefits and economic opportunities. Electricity, in modern life, is the foundation and lifeline for communities and economies to run and thrive. There is a growing international acknowledgement of the strong ties between poverty and lack of access to modern energy. For example, in impoverished communities, peoples’ well-being is in grave danger, because of the use of dirty … Continue reading →

Energy management is the best solution for direct and immediate reduction of energy consumption for businesses and households. For the last few decades we have been exploring various alternatives to conventional sources of energy like solar, wind and biomass energy. However, due attention must also be given to best utilization of energy, improvement in energy efficiencies and optimum management of energy resources. Infact, energy management deals with already existing sources and actual consumption. It includes planning and operation of energy-related production and consumption units. The main objectives of energy management are resource conservation, environment protection and cost savings. The central … Continue reading →

Waste-to-Energy Pathways: An Overview

By | | ,
14 Comments

Waste-to-energy is the use of modern combustion and biological technologies to recover energy from urban wastes. The conversion of waste material to energy can proceed along three major pathways – thermochemical, biochemical and physicochemical. Thermochemical conversion, characterized by higher temperature and conversion rates, is best suited for lower moisture feedstock and is generally less selective for products. On the other hand, biochemical technologies are more suitable for wet wastes which are rich in organic matter. 1. Thermochemical Conversion of Waste The three principal methods of thermochemical conversion of MSW are combustion (in excess air), gasification (in reduced air), and pyrolysis (in … Continue reading →

An Introduction to Solar Pond

By | | ,
2 Comments

A solar pond is a three-dimensional, open-air pit, filled with water endowed with special properties. It receives solar energy through insulation, then the trapped heat is extracted from it from the water lying at the bottom of the pond. When solar energy falls onto the pond, it heats the water, splitting it into three sections: the first section is the uppermost layer, or Surface Zone, containing fresh water with a low level of salinity. This owes to the fact that salts gather at the bottom. The second layer is the middle layer, called the insulating layer or Insulation Zone, whose … Continue reading →
