Finance Minister AHM Mustafa Kamal has called the nation's experts and policy-makers for extensive research to find new ways of energy production.
"Producing energy from fossil fuel is not the right way. We have to change the methodology…," he said at a two-day clear energy summit recently.
Climate change is an issue of a serious concern for mankind because of excessive carbon emissions from fossil fuels, Mr Kamal said.
He said 80 per cent of global energy is coming from fossils that are degrading the environment and everybody globally has been suffering from it.
"We have to work for green energy," the minister said, adding: "We need renewable energy to save humanity, to save earth, to tackle climate change."
He exhorted all to raise voice loudly to reduce carbon emissions with a view to saving the climate and protecting future generations.
