In terms of renewable energy capacity in Bangladesh,
Table 4 presents the number of capacity additions from solar sources in the activities undertaken from 2018 to 2022. In
Table 4, it can be seen that the solar generation capacity addition in 2018 is about 40 MW, and the maximum generation capacity increase is in 2021 at about 170 MW. Further, the production capacities of 54 and 64 MW have been added in the years 2020 and 2022, respectively, while 43.73 MW was added in 2019.
4.6. Energy Generation and Carbon Savings
Carbon dioxide (CO
2) emissions are often measured as elemental carbon in kt (kilotons). The installed capacity of renewable energy systems as sources in Bangladesh and the expected energy generation from them are presented in
Table 76. Furthermore, the amount of carbon emissions reduced by the electricity generated from each source is shown in the third column. It can be observed that the highest carbon dioxide-emission reduction was achieved through large hydro systems with a capacity of 230 MW and an expected energy generation of five trillion-watt hours, which is the highest among other technologies.

4.9. Progress of Renewable Energy Share in Bangladesh
Table 119 presents the year-wise population growth and population growth rate of Bangladesh, GDP growth rate, and renewable energy share. It can be observed that the population density growth of Bangladesh has not changed much between 2015 and 2022, but the GDP growth rate has increased slightly between 2015 and 2019 and decreased to 3.45 percent in 2020, which then increased in 2021 and 2022, respectively, from 6.94 percent to 7.20 percent.

5. Obstacles to Achieving SDGS in the Renewable Energy Sector
Bangladesh is a densely populated country. The number of landowners is high relative to the number of many small plots of land with the potential for setting up plants. Although there is a large amount of land suitable for setting up large-scale solar projects, it is the property of many landowners. As a result, more time has to be spent on land acquisition and legal processes
[74][31]. Large areas along the rivers of riverine Bangladesh are considered to be suitable for setting up solar plants, but as these are lowlands, most of the rivers are flooded every year. Therefore, in order to implement solar projects, additional funds have to be spent on structural development in these places
[75][32].
There are only two grid-connected solar projects in Bangladesh, one at Jamalpur’s Sarishabari and the other at Teknaf. In most cases, skilled engineers have to be brought in from other countries to solve problems with these. An analysis of the two ongoing projects shows that there is a large shortage of skilled engineers and human effort to implement large-scale solar power projects
[76][33]. The amount of energy produced from solar power depends on the elements of nature, such as light intensity, dust, and the presence of light. As these elements of nature change, the rate of power generation decreases or increases. As a result, the grid to which solar power will be connected has to endure these changes and various unforeseen errors
[77][34]. To cope with such a situation, the national grid of Bangladesh has not been enriched by modern technology to a large extent.
Technical standards and codes are required at the national level for the implementation of large projects. Skilled suppliers are reluctant to implement projects considering the risks involved, as there is no code or standard for implementing large projects through solar technology. It has also been suggested that bureaucratic complexity is one of the major obstacles to the spread of renewable energy. Although it is now mandatory to conduct online purchases of goods and services, in some cases more than twenty approvals are required to allow a service provider to start with a project plan. Such conditions can be considered one of the major obstacles to achieving set goals.
