Dhaka, Nov 13, 2009 (Asia Pulse Data Source via COMTEX) -- GLENE | Quote | Chart | News | PowerRating -- Solar-power systems on rooftops of high-rise buildings in urban areas would greatly help to ensure uninterrupted supply of electricity with a view to overcoming the present energy crisis, expert said.
?We need a sustainable energy source, which can ensure our continuous supply of electricity,? said Dr. Mohammed Ataur Rahman, director, Program on Education for Sustainability, Centre for Global Environmental Culture (CGEC) of IUBAT.
The government should immediately make it mandatory in the building code for the households to install solar systems on rooftops of high-rise buildings for generating solar energy, which has already been mandatory in the West Bengal of India, he told UNB.
Dr. Ataur Rahman recently presented a paper at a seminar on `Solar Energy for High-Rise Buildings in Urban Areas? at the Conference Hall of IUBAT (International University of Business Agriculture and Technology).
He described solar energy as the ultimate energy source of the lives on the earth having easy solution to substitute the conventional energy sources and said all plants and animals are using solar energy, which is trapped by the green plants during photosynthesis. ?By trapping solar radiation and converting it to electric energy is an answer for sustainable energy for Bangladesh.?
Dr Ataur Rahman, also chief consultant of Forestry, Environment, Plantation Crops and Pharmaculture Consultancy and Research (FEPPCAR), said solar energy has been used by humans for thousands of years and ancient cultures used energy from the sun to keep warm by starting fires with it.
"They also kept their homes warm through use of passive solar energy," he said, adding that buildings were designed so that walls and floors collected solar heat during the day and released same at night for warmth.
Nearly 300 megawatts of power can easily be generated from solar energy to feed the hungry national grid if solar-power systems are installed on rooftops of some 20,000 multistoried buildings in capital Dhaka, he said.
