How greenhouse effect works

The greenhouse effect is the process by which the earth’s surface and its lower atmospheres are warmed up. Its mechanism was first suggested by Joseph Fourier in 1824 and experimentally confirmed by John Tyndall in 1860 [1]. Since then, much effort has been devoted to fully understand its mechanism, causes and consequences. (more…)

Global warming

In the previous article, we discussed primarily natural climate change and anthropogenic climate change. Further, we realized that the global warming was just one indicator of the changing climate but was the most dominating, most damaging sign of the current changes in the climate system. In this article, we will focus on the global warming.

Manmade environmental damages and their impacts on the climate [ctd.]

Industrial revolution which happened during the late 1700s and early 1800s is simply the process in which rural, agrarian people in Europe and North America became urban and industrial. It began in the United Kingdom and soon after, spread to nearby countries changing the processes of manufacturing and eventually the whole lifestyle.

Sanity Has Prevailed – No More Coal Power Plants

Sri Lanka and those of us who have battled for decades to highlight the dangers posed by use of coal for power generation, both for the environment in general and the health of the people without exception, can at last heave a sigh of relief. It is hardly necessary to emphasize that Sri Lanka not having any indigenous coal reserves, had no compulsion to even consider this option until all other options are exhausted. In the recent years the whole world including those countries with vast coal reserves on their own, are opting out of this option. But let that be a matter in the past. (more…)

Engineer’s Role in Renewable Energy Utilization in Sri Lanka

Abstract of the Video

The origin of energy used by the world is solar. The pre-historic human being used solar, the very original form of energy, to meet the energy needs. With the development of technology, he changed the mode of energy, where instead of using the energy received by him from the sun right at the time of use, he had to wait millions of years to use it as petroleum resources explored from the earth core.
