The main barriers to renewable energy in their paper are economic, financial, political and technological. However, we are still lagging behind in the scientific use of this renewable energy, due to a lack of technology and efficiency in this area.

Reasons of use renewable Energy
In addition, the costs of renewable energy discoveries have fallen steadily and are significantly worse than expected. On the contrary, the cost of non-renewable energy sources can vary considerably and tend towards liberal prices.

They may be the world's biggest polluter; However, China is the world's largest financial expert with renewable energy levels abroad and abroad. Yet it is one of the world's biggest fuel retailers, which opposes its renewable limits.

- Hydro Energy
- Biogas Energy
Due to the high priority initiative of the PV grid system, this area should have a standard approach. Compared to the general matrix, the country's first solar plant is now fully operational on a remote island in the dunes. Tragically, very little research has been conducted in these areas, even as of late 2000.
Expansion, the concept of windpipe regions from a sustainable energy era and the air guarantee of the islands. The dots show a diurnal cycle with maximum crusting and weakening in the evening (relatively West Bengal, India, comparison patterns). The wind speed estimates from the BCAS group and the GTZ group confirm that the speed is significantly higher in the summer months than in the winter months.
Kaptai Lake is said to have provided a large energy reserve due to the development of the Kaptai River Dam.
More interested groups
By using biogas burners for the past two years, a portion of the Shahnaz hills has resulted in fish with an organic fish-like smell. 19 In 1975, Hessar Biogas' successor position in the world of biogas and medical in Bangladesh peaked with cooking, although it was included in the late 1990s. Located next to the quota of 44,000 biogas plants of the Government of Bangladesh in Infrastructure Profiler Print of Limited (IDCL), it has a final share of about 200,000 people.
Plans ahead
Biomass Energy
Which today launched the country's best-in-class decentralized biomass control center in a joint effort with the World Bank and global environmental benefits. IDCL has received and has been recognized by IDA and Global Environmental Benefit (GEF) for the combined income of 25 million of the World Bank's 0% paid up joint income. Asaduzzaman Manik, who oversees the main Dreams Power The plant, located in a shaky region, currently supplies waterproof quality mesh outside blue to approximately 500 family units and business elements around the world.
The World Bank supports such activities in Bangladesh through the Rural Electrification and Renewable Energy Development Project, commonly known as RERED. The World Bank believes that IDCL will relocate Bangladesh's biomass control centers in the province to similar sunflower house frames. In addition to supporting the overall grid-based energy sector, it is Bangladesh's comparative priority in sustainable energy sources and the World Bank's valuable.
Since Bangladesh does not have an adequate electricity age limit, the shift to these decentralized sustainable energy source control centers will increase the country's vitality security and take care of the essential energy demand.

The Center for Wind Energy Technology's (CW) analysis of high-atmospheric data analyzes that grid-connected resources (<7 m/s) due to grid winds are not sufficient to generate electricity in most parts of the country. Abnormal warming of the climate causes the surface temperature of the earth to rise, resulting in airflow. The gearbox increases the rotational speed of the generator which uses interesting fields to change the electric density's rotating lifetime.
The power goes to the transformer, which is converted from the generator to the correct voltage in the electrical transmission structure [19]. In the unexpected method, wind turbine operating rules are simply the opposite of a fan. By separating the weight of the wind in different ways, this region is valuable for aviation.
We have taken half of the beachfront area (26,700 m2), presumably for wind turbines, and another 30% of the area for activity coordination, industrial space and reliable worker housing and offices.

On the first day of January, the sun's first N = 1 10 solar radiation differs from radiation in the same region of the opposite surface, it is detected from the sun. A utility is available through the power company: There are two types of sunlight-based power generation structures: Network-related structure, which is related to business-based organizations;. The electricity generated during the day can be used immediately, and electricity and power plants can be sold again.
Electricity levels and excess can be tested on a regular screen, a mandatory method of measuring daily life. Crisis control framework is used which is used with crisis control supplies and remote access is not available on current basis. As the sunlight fades in Figure 2-2, an electron slows down and n-type tugs are pulled.
This creates more negative electrons between the n-type semiconductor and more positive electrons, which creates the type of flow of type P-type - which is known as photovoltaic effect.

Photovoltaic is primarily used to control small and medium-sized appliance application, which is controlled by closed-matrix domestic photovoltaic clusters controlled by single-sun-based crutch control controllers. They are the essential and common economic successor, which means that the photovoltaic framework (PV framework) uses a panel based on the sun. Alternatively, it may include a great Powerpoint tracker (MPTP), a battery framework and charger, a sun-based tracker, animated admin programming, a sun-based collector, or other hardware.
Due to the normal reduction of PV modules voltage due to temperature and 15V or more voltage for the battery, there can be 36 solar-based cells in most modules. An intelligent Silicon Sun powered cell contains only 0.6 degrees Celsius 25 degrees Celsius and 1.5 meters lighter voltage. When a solar-based cell is covered, the remaining part is not the module, the energy produced by the "big" solar-based cell can be distributed at the hip by the rotating cells below.
PV modules are created when the electrical parameters of the solar cell remain constant compared to the rest of the gadget.

This does not reduce the current level of portable power required by the blocking diode, but closes the parallel string current write of the lower strings and thus limits the split losses generated in the parallel connected strings. All things are thought to be part of the unit or the whole station at once. The project was initially targeted at Austrian Strait Islands (Kishoreganj), Shingra (Natore), Kotalipara (Gopalganj), Mosekhali, Kutubdia and Bay of Bengal sub-centres.
Candidates should be aware of the general public for importing GOV solar cells using solar panels and sponsors. It is located in the east, west and north sides and south of the Bay of Bengal. Before focusing on issues related to life and financial impact, the basic point of this exam is to make a general picture of the situation and condition of city and family unit in the unit.
At that time, different parts of the structure, for example the Charge Controller Unit and Voltage Converter (if necessary), are selected.

After evaluating the stack in the first stage of this stage and after this measuring the battery. If you want to know the daily average load, a family consists of 4 people who use TV for 5 hours, 6 LED bulbs for 6 hours, 3 fans for 15 hours a day, laptop for 1.5 hours. Solar module As a DC output voltage, this structure requires a DC-DC converter or a DC-AC converter.

CONCLUSION
It is clear from the above study that we have enough opportunity to solve the problem by setting up renewable resources such as solar system in each regional area, wind plant, biogas plant and hydroelectric plant which require the capital to installation cost. it doesn't have to wear. cost. Using the most advanced solar, wind, biomass based projects and solar powered equipment will be a definite way to meet the future energy needs of Bangladesh. The installation of renewable energy (solar energy, bio-energy, mini-wind energy, etc.) offers a cheap and sustainable way to provide high-quality, reliable, clean and clean, and environmentally friendly services.
Renewable energy can provide better ancillary facilities in education, recreation and communication in rural areas and can improve certain commercial activities as well as the living standards of the rural community.
It has a great impact on the lives of our rural people in Bangladesh by giving them numerous direct and indirect socio-economic benefits.
