Abstract
This paper discusses the evolution of various energy resources, their reserves, and usages for policy makers and energy experts. It finds that there is a huge supply-side deficit to meet the demand of the 7 billion people in today's world. To meet this huge energy needs, alternative energy sources are investigated and suggestions are made to address energy crises in Bangladesh and global contexts. The author argues that with the advancement of technology, a completely new nuclear meaning thorium reactors, small modular reactors, and novel solar technologies can offer potential alternatives to meet the needs of mankind. In addition, developing cost-effective carbon capture storage devices to catch carbon at its generating sources, energy storage devices, and energy culture model can be explored. The search for alternative technologies and energy culture require robust discussion, cooperation, and investment in clean energy sources. The paper concludes with a discussion of future energy policy and appropriate action plans to adopt emerging alternative technologies as per the promises made at the Paris Climate Change Accord COP21.
Highlights
Energy means the ability to perform useful work
As forests were cut and wood supplies dwindled at the onset of the industrial revolution in the mid-18th century, charcoal was replaced by coal in the reduction of ores [1]
The objective of this paper is to provide a brief summary of global and Bangladesh energy crisis based on available resources and usages and of possible paths to the future
Summary
Energy means the ability to perform useful work. It has different forms, i.e., light, thermal, chemical, mechanical, electrical, nuclear and the like. Discovery of fire by rubbing stones a million years ago during the early Stone Age is the thermal form of energy. This was the only knowledge for human ancestors to make a fire but they did not have fire making skills. Certain other energy sources found only in localized areas, were used in ancient times; natural peat, natural wood charcoal, and coal from surface deposits and oil from seepages of underground deposits [1]. Bangladesh has a per capita energy and electricity consumption of 276 KgoE and 348 kWh, respectively, which is one of the lowest in Asia [11, 19]. 15% have access to electricity, and the rest mainly depends on traditional biomass
