The document discusses renewable energy sources that could help solve Bangladesh's energy crisis and support sustainable development. It outlines various renewable sources available in Bangladesh including solar, wind, biogas, biodiesel, micro hydro, ocean wave, tidal, and geothermal energy. These sources have good potential to generate electricity and help meet the country's growing energy demands if developed further with support from the government and private sector. Renewable energy could also improve rural livelihoods and allow Bangladesh to export excess power in the future.

3.  Electricity is a very important factor in developing the economy and
the standard of living of a country.
 Now a day, Bangladesh is facing energy crisis. In Bangladesh, around
70% of people having lack accesses to electricity and most of them
are living in the village. Among them about 40% of them are living in
below poverty line. On the other hand climate change puts addition
threats to development.
 To solve this energy crisis we can use different form of renewable
energy to generate power. Renewable energy is the energy that
comes from different types of natural resources mainly from
sunlight, wind, rain, tides, and geo thermal heat, biodiesel, biofuel
etc.

5. SolarEnergy
Solar Energy
 Bangladesh can produce sufficient amount of electricity by solar
energy. Because Bangladesh is a subtropical country, 70% of year
sunlight is dropped in Bangladesh. For this reason, we can use
solar panels to produce electricity largely. Almost every newly
built apartment building is now using solar panels along with the
grid connection to get support during the load shedding period.
Even in the rural areas, some NGO’s have been working to provide
solar panels to the villagers at a cheap price.

Solar Energy
Solar radiation varies from season to season in Bangladesh.
Bangladesh receives an average daily solar radiation of 4-6.5 kWh/m2.
Maximum amount and minimum on November
December-January in the following figure 2. Bangladesh is situated
between 20.30 and 26.38 degrees north latitude and 88.04 and 92.44
degrees east which is an ideal location for solar energy utilization.

Figure-4 Shows that the approximate division wise SHSs (Solar Home System)
installation. The distribution of the SHSs is highest in Dhaka district whereas
lowest in the Sylhet.

8. WindEnergy Wind Energy
 It has a great potential to recover electricity by wind energy for
Bangladesh. Wind power involves converting wind energy into electricity
by using wind turbines. A wind turbine is a machine that converts the
kinetic energy in wind into mechanical energy. Coastal locations of
Bangladesh such as Chittagong, Noyakhali, Bargona, Bhola, Kutubdia and
Cox's Bazar have huge potential to produce electricity from wind
energy.

From the above figure 5, we can see that maximum velocity (5.98 m/s) in
the month of August in the place of Kuakata and the minimum velocity
(1.20m/s) in the month of December in the place of Rauzan.

10. BiogasEnergy Biogas Energy
 Biogas naturally mentions to a gas produced by the biological
breakdown of organic matter in the absence of oxygen. Organic waste
such as dead plant and animal material, animal dung, and kitchen
waste can be converted into a gaseous fuel called biogas. Many
countries now-a-days are producing electricity from biogas. In Bangladesh
biogas is still a comparatively new technology. In most of the places it is
used to generate electricity to meet the household demands. It should be
used commercially to produce electricity in the areas where there is still no
electricity from the national grid. It will help the people of these areas to
meet their demand of electricity and the government and the
companies related to this technology can earn money which is also
beneficial.

11. .BiodieselEnergy Biodiesel Energy
 Biodiesel is one of the alternative ways to generate renewable power or
energy. Now a day’s fossil fuel depletion and global warming issues are the
point of concern around the world. To reduce Carbon emissions and
decreasing reserves of fossil fuels, Biofuel can be an attractive source of
energy. Next generation biofuels can be a great solution to the global
warming and the crying need of fossil fuels.

13. MicroHydroEnergy Micro Hydro Energy
 Because of the geographic position, Bangladesh is a riverine country
which is a huge advantage for the country. This huge amount of
river currents and sources of low head of water falls can be
used for generating micro hydro-power. Micro hydro means
generating up to 5-300 KW of electricity through hydroelectric
power. It is a simple technology that converts hydropower to
mechanical power. Micro-Hydro technology is very much suitable for
a developing country like Bangladesh .

14. OceanWaveEnergy Ocean Wave Energy
 Ocean wave energy is generated directly from the waves of the oceans.
It is another special type of renewable energy which helps to
decrease the harmful emissions of greenhouse gases associated with
the generation of power. It can be potentially a significant source of
electricity for Bangladesh. Though the main purpose of ocean wave energy
is electricity generation, it can also be used for the pumping of water, water
desalination etc.

15. TidalPower Tidal Power
 Tidal power or tidal energy is a form of hydropower that converts the
energy of tides into electrical power. Among these coastal areas, with 5
meter tides experienced, Sandwip has the best prospect to generate
tidal energy .

16. GeothermalEnergy Geothermal Energy
 Geothermal is another way to generate power or energy which is
renewable power or energy. The thermal energy which is generated and
stored inside the earth surface is called Geothermal energy. It is very
much cost effective and environmentally friendly. The northern districts of
Bangladesh show the prospect to explore the geothermal resources. The
demand of electricity in urban as well as in the rural areas are
increasing, but our production of electricity is not increasing. A Dhaka
based private company namely Anglo MGH Energy has initiated a project to
setup the country’s first geothermal power plant with a capacity to
produce 200 MW of electricity close to Saland in Thakurgaon district.

17. Conclusion Conclusion
 Renewable energy sources discussed above can help Bangladesh produce
more power in order to reduce Load-shedding problem.
 It has a great impact on improving the socio-economic condition of rural
people as well as will be a good sign of green energy technology.
 With the help of these resources Bangladesh can make sustainable
development and export electricity meeting the internal demand in the
future.
 Therefore, the Government and the Private sector should work hand in
hand to emphasize more on renewable energy source to produce
electricity to solve our power crisis problem and sustainable develop our
county faster.
