Renewable energy aspects and Bangladesh

Popular News

Renewable energy is energy that is collected from renewable resources that are naturally replenished on a human timescale. It includes sources such as sunlight, wind, the movement of water, and geothermal heat. Although most renewable energy sources are sustainable, some are not. For example, some biomass sources are considered unsustainable at current rates of exploitation. Renewable energy often provides energy for electricity generation to a grid, air and water heating/cooling, and stand-alone power systems. Renewable energy technology projects are typically large-scale, but they are also suited to rural and remote areas and developing countries, where energy is often crucial in human development. Renewable energy is often deployed together with further electrification, which has several benefits: electricity can move heat or objects efficiently, and is clean at the point of consumption. In addition, electrification with renewable energy is more efficient and therefore leads to significant reductions in primary energy requirements.

Global energy demand has risen sharply over the years with developing countries recording the greatest share in this trend. Renewable energy stands in contrast to fossil fuels, which are being used far more quickly than they are being replenished. Rapid deployment of renewable energy and energy efficiency, and technological diversification of energy sources, would result in significant energy security and economic benefits. Solar and wind power have got much cheaper. In some cases it will be cheaper to transition to these sources as opposed to continuing to use the current, inefficient, fossil fuels. It would also reduce environmental pollution such as air pollution caused by the burning of fossil fuels, and improve public health, reduce premature mortalities due to pollution and save associated health costs that could amount to trillions of dollars annually. Multiple analyses of decarburizations strategies have found that quantified health benefits can significantly offset the costs of implementing these strategies.

Climate change concerns, coupled with the continuing fall in the costs of some renewable energy equipment, such as wind turbines and solar panels, are driving increased use of renewable energy. As of 2019, however, according to the International Renewable Energy Agency, renewable overall share in the energy mix (including power, heat and transport) needs to grow six times faster, in order to keep the rise in average global temperatures “well below” 2.0 °C (3.6 °F) during the present century, compared to pre-industrial levels.

Bangladesh is among the five fastest growing economies in the world. Yet, the country’s sustained economic expansion increased the energy demand and strains existing energy infrastructure.  Keeping energy access reliable and on a low enough price to be affordable for everyone, has been a continuous struggle over the past decades. A decentralized renewable energy system presents a massive opportunity for Bangladesh to accelerate economic development, whilst improving energy access, livelihoods and the health of millions of people in a sustainable manner.

According to Sustainable Renewable Energy Development Authority (SREDA), energy insufficiency is obstructing the socio-economic and industrial improvement of Bangladesh .The government and the private sector should work hand in hand to emphasize more on renewable energy sources to produce electricity to solve the power crisis problem in Bangladesh.  As the stock of fossil fuel is decreasing day by day, more emphasis should be given on renewable energy sources to meet the global power demand. The government and non-government organizations are working both independently and jointly to promulgate renewable energy technologies (RET) throughout the nation. Therefore, prospective planning and comprehensive understanding of this dynamic field require continuous assessment. Moreover, the progression, as well as regressions, in this sector should be continually scrutinized.

Bangladesh is on a trajectory to becoming a middle-income country and is striving to become a developed nation by 2041.  Transitioning to clean energy would allow Bangladesh to diversify its power mix, reduce the risks associated with the volatile prices of fossil fuels, and decrease the negative environmental impacts of thermal power generation. To meet the near future demand, Bangladesh needs more sophisticated research facilities and skilled manpower for exploration activities both inland and offshore areas. The government must work with international advanced technology using human intellectuals of the country for energy sustainability. Renewable energy can be considered as a potential alternative to conventional energy that comes from fossil fuel. Currently, there is an immense interest in the use of renewable energy like solar, biofuel, geothermal, wind due to environmental and economic concern. The government of Bangladesh has put significant effort and target to establish different projects on renewable energy which also subsidized by the government.
