Sustaining Renewable Energy

Sustaining Renewable Energy By Dr Arvind Kumar T he success, thus far, of fossil fuels in meeting energy demand any time required has led to a belief that whatever we want we can always have whenever we want it. This of course is leading to problems as it patently can no longer be maintained. It also has lead to the development of quite unrealistic expectations as to how far renewables can replace fossil fuels. Renewable energy is being tagged on to a massive existing demand led fossil fuelled energy system that has historically recorded tremendous growth. Efforts at demand reduction and increased efficiency have seemingly resulted in slight savings and these are often deferred by people opting for higher comfort levels. Viewed in a broad spectrum, almost all the renewable technology presently installed has only made us 96% fossil fuel dependent rather than 100%! This is a cause of worry as to the very extreme degree of energy descent that may be experienced as we move further in...

Avoid Plastic and Save Environment

Avoid Plastic and Save Environment Plastic is like a common commodity which is essential in our daily lives. Bakelite, nylon and rubber are some examples of synthetic plastics. Almost everything is made of plastic! They are very convenient to use because of their malleability and plasticity. They can be easily moulded by heating. Plastic product may be non-toxic, but some small amounts of the chemicals remain trapped in the product. As a result, when these plastics come in contact with food stuffs, the chemicals mix with the food which we subsequently consume. Plastics are non-biodegradable solids. When we burnt, they release some toxic fumes which cause ozone depletion and pollution; many chemicals are released into the air as well as into water. All these bear hazardous environmental consequences. Plastics are made of crude oil and can be used as fuel. One litter of hydrocarbon is produced from one kilogram of plastic waste. Over 1 trillion plastic bags are used every year w...

Kisan Divas

Kisan Divas By Dr Arvind Kumar 23 December is celebrated as Kisan Divas or Farmers’ Day to commemorate the memory of Chaudhary Charan Singh, whose life reflected his peasantry background and he understood problems of the farmer and did his best to help them. The plight of farmers in India has been very miserable in present-day India and they have always been at the receiving end since Independence. Their hard toil fetches them nothing except fake assurances from the dispensations at the helm. It’s sad and unfortunate that people who are indispensable for the growth of nation have been left to their fate. This is quite evident from the suicide cases in Maharashtra, Andhra and other parts of the country including West Bengal. In state like UP middlemen and Mandi officials ensure that the farmers turn into object of grief. The need of the hour is implementation of schemes introduced by the government. This can take place effectively if the village panchayts are provided more powe...
