Role of The Private Enterprises in RET
The Private Enterprises has been playing vital role in the RET field as:
• Technology Provider & System Designer
• System Integrator
• Component Provider

Contribution of Private Enterprises to RET
• Inputs in developing & improving the Policy
• Market development by creating awareness
• Capacity building
• Customized solutions
• Service facilities
Future Role of Private Enterprises to RET
• Development & improvement of technology designs
• Innovative solutions to both rural & urban sectors
• Creating more awareness
• Spreading knowledge through training & development
• Enhancing manufacturing and service facilities
• Scale up implementation of RET
Role of Private Financial Institutions
• Private Financial Institutions could extend soft loan facilities to the end-users of RET
• Micro Financial Institutions could provide loan to the end-users as well
Role of Corporate Houses
Incorporate and implement Renewable Energy Applications wherever possible for sustainability in terms of environment & long term return.
Way Forward
RET in Bangladesh could only be sustainable when there will be concerted effort from Government, Private Enterprises and other Development Agencies.

Green House Gases (GHG)
• GHG act as a blanket that retains solar heat in the atmosphere
• Direct GHGs are
– Carbon dioxide (CO2)
– Methane (CH4)
– Nitrous oxide (N2O)
– Hydrofluorocarbons (HFCs) and
• Indirect GHGs are
– Carbon monoxide (CO)
– Nitrogen oxides (NOx)
– Non methane volatile organic compounds (NMVOC)
– Aerosol precursor sulfer dioxide (Sox)
Global Warming Potential (GWP)
• GWPs indicate greenhouse gases’ relative heat-trapping effect. The higher the global warming potential of a gas the greater the contribution to the greenhouse effect.
• Based on 100 year GWPs the default values of the Revised Intergovernmental Panel on Climate Change (IPCC) Guidelines for Greenhouse Gas Inventories, 1996 are-
|
GHG |
CO2 |
CH4 |
N2O |
|
100 year GWP |

296 |
IPCC reference approach for estimating CO2 emissions
The estimation process is divided into six steps that
lead to figures for CO2 emissions for fuel combustion-
-
Estimate consumption of fuels by fuel/product type
-
Convert the fuel data to c common energy unit (TJ)
-
Select the carbon emission factors for each fuel/product type to estimate the total carbon content of the fuels
-
Estimate the amount of carbon stores in products for long time
-
Account for carbon not oxidized during combustion
-
Convert emissions of carbon to full molecular weight of CO2
CO2 emission from grid electricity
In 2004 national grid produced
20062.13MkWh electricity
9x106 tCO2
Impacts of Solar energy systems on GHGs mitigation
• Solar energy doesn’t produce GHGs
• It can be utilized as
• isolated from the grid or
• tied with the grid
• IDCOL, Bangladesh has given assistance to
– 170000SHS
– 30W each (say)
– Working hour 4/day (say)
– Base case grid
– These are now saving ~3366tCO2/year
• In the grid fuel mixture solar energy can be adopted
in greater amount by using grid tied technology
• It will reduce the GHGs/MWh
