National Exhibition and Seminar (Title : Climate Change Mitigation : Role of Renewables) on Renewable Energy . Dhaka, Bangladesh, 24-25 March, 2008
Focus on Climate Change Mitigation: Role of
Renewable
Self-similar nature of solar radiation: Modeling and estimation
Runa Rukshana Khan, Md. Muhidul Islam Khan, M. Ismail Jabiullah and Shahida Rafique
Key features
l Self-similar nature of solar radiation has been observed in a Time series data from 1988 to 2007
l The mean variance, autocorrelation auto covariance etc have been computed by statistical model
l It has been realized that the structure of radiation shows similarity at arbitral small scales
Prediction of performance
l It contains smaller replicas of itself at all scales. At every step the each portion of the cantor set is an exact replica of the full set in the preceding step. This leads to the observation that passion traffic, may not accurately predict the performance of solar radiation
Sample data
Analysis
l Mean, variance
Graphical Presentation sunrise for jan 1988 and 1989
Sunshine 1988 to 1997
Auto Correlation Mathematically & graphically
Conclusion
Mean, variance for every year almost same. Autocorrelation has been computed The structure is repeated
The self similar nature of solar radiation.
Technology, People’s Participation and Future Challenges: In the Lens of Climate Change

Introduction
n There has no society that does not have change as changing is an inevitable process of social dynamism
n Knowledge of development does not mean merely a change but many more.
n Bangladesh like other developing country is very lack of utilization of advance technologies from per capita perspective
n It is imperative to increase Per capita advance tech use to make the country’s faster growth and improving the livelihood of the people
n Yet the country is unable to make a pro people national tech- policy.
Topics of Discussion
n 1. Review the status of tech utilization in livelihood development in Bangladesh
n 2. Exploring the status of technology use in livelihood improvement in the rural household
n 3. In search of people’s perception of new technologies, predicaments of mass utilization and recommendations to meet future challenges
n
Status of the Tech. Use
n The people of developing countries spend very less compare to develop countries in the R& D.
n They spend a small proportion of GDP on research and development: less than 1 percent, compared to high income countries that spend around 2.5 percent.
n Alike other developing countries the People of Bangladesh are under developed as they are back behind from modern technology.
n In Bangladesh the majority of the population does not know how to read and write,
n Half of the people live in under poverty line,
n Per capita energy consumption is only 150 Cal. Where as it is about 5 thousand in developed countries.
n In Bangladesh Per Capita electricity consumption is around 200 Kilowatts that is 1/5 compare to India, Srilanka and Pakistan
“ Traditional plow and cow are the main energy for the farmers for cultivation. Tractor and power tiller are not being used here. Driller, weeder, thresher these kinds of advance tech are not been used but grinding machines are used for paddy and wheat grinding” – a result of research findings on a coastal village
Scope of Solar energy
“ Radio, TV and mobile are as precious as a golden dear” – A research finding in Charland
“ We did not have electricity but we met the emergency injury patients at the very end of the storm surge by using candle light”

Technology Transfer
People’s Participation
New Chula:
All the participants have ‘new Chula’ (17 women)
n They commented that it reduces the cost of fuel
n It creates less smoke
Solar Energy:
Participants Opined that peoples have demand
They are more willing to pay compare to traditional PBS customer
n To enhance the economic growth as well as improve the livelihood of the people it requires to increase the per capita energy intake at-least double
n To meet the challenges of Climate change and its adverse affect there is imperative to improve the capacity of people to cope with disaster
n It urges to develop Pro people tech policy for achieving the MDGs and PRSP
n Last but not least National Tech Policy and Tech transfer strategy should be developed through multi disciplinary approaches
