After the industrial revolution, the world came to depend on fossil fuels as the main energy source. This helped to create extraordinary economic growth, great advances in living standards and prosperity for many. Unfortunately, there is a downside. The burning of fossil fuels releases enormous amounts of pollutants and carbon dioxide into the atmosphere. For more than a century, humankind has been relying on an energy source that is dirty, finite and changing the climate irreversibly. Over the next decades, however, a great shift away from fossil fuels will take place. Technology improvements and cost reductions are remarkably fast, in particular for solar and wind power. Their share in power generation could climb from 5 per cent today to 30 per cent by 2040, even if support from subsidies were phased out after 2020. A comparative forecast picture is given below:
Going greener: Global installed power capacity, share of totalSource: Bloomberg New Energy Finance, New Energy Outlook-2016
This above data shows that renewable energy contributing only 4 per cent share of total global installed power capacity in 2015 will contribute about 29 per cent share of the same (according to forecast) within 2040. Solar cells are made from light absorbing materials that convert sunlight into electricity. Today most often it is silicon, a brittle material that needs to be encapsulated and mounted in a rigid frame to make it durable. This limits the panel’s deployment to rooftops or large installations in fields. Still, according to The Future of Solar Energy, a report from the Massachusetts Institute of Technology (MIT), today’s silicon-based solar-cell technology is sufficiently good to be widely scaled up by 2050 to achieve large reductions in carbon emissions, even without major technological advances. In addition, batteries are getting better and cheaper, and many serve as an enabler for electric cars, as well as for absorbing more energy from renewable into the grid.
Bangladesh is a country prone to disasters like flood, river erosion, cyclone, drought, etc. Green house gas emissions and use of fossil energy which produce more carbon dioxide in the air affects our climate. Increase of population, habitation, urbanisation, industrialisation, movement, industrial and commercial activities of people add to worsen this situation. So, in this time, we should think about more green energy which is favourable to improve climate. Recently Solar Energy is gaining popularity among the people and people are using it for its many advantages. It comes from renewable energy source, reduces electricity bills, diverse application, low maintenance cost and technology development driven. Bangladesh has attained and shown tremendous success to install and expand solar energy. But we will have to go a long way. A short term, mid-term and long term policy should be taken for exploiting the maximum benefits and reaping the most from this source of power.
Spanish (Spain) initiatives: Spain has launched an ambitious plan to switch its electricity system entirely to renewable sources by 2050 and completely decarbonise its economy soon after. To do this, the country’s Social Democratic Government is committed to install at least 3,000 MW of wind and solar power capacity every year in the next 10 years. New licenses for fossil fuel drills, hydrocarbon exploitation and tracking wells will be banned and a fifth of the state budget will be reserved for measures that can mitigate climate change. It sets a long-term goal, provide incentives on scaling up emissions technologies and care about a good transition for the workforce. By planning on going carbon neutral, Spain shows that the battle against climate change is deadly serious, that they are ready to set up and plan to reap the rewards of de-carbonisation. Bangladesh Government has emphasised on power generation through renewable energy. This would especially meet the demand in areas where grid supply is not possible. According to Renewable Energy Policy-2008, 10 percent of electricity is to be generated from renewable energy sources by 2021. Government has established Sustainable and Renewable Energy Development Authority (SREDA) in 2014 under Sustainable and Renewable Energy Development Authority Act, 2012. The establishment of SREDA is aimed to provide dedicated institutional support to promote renewable energy. We think a short term, mid-term and long term program will be taken soon to materialise and fulfill our demand to be self-sufficient in the power sector from this natural source of energy.
