India needs all kinds of clean energy: AEC chief
Chairman of Atomic Energy Commission Srikumar Banerjee said here on Thursday that there is a need for increasing the carbon-free sources of energy that is a combination of nuclear, renewable, and fossil fuels with “sequestration.”
He was delivering the 30th annual convocation address at Mangalore University.
“It is necessary to stabilise atmospheric concentration of CO2 (carbon dioxide) in the range of 600-650 ppm (parts per million).”
He said the traditional energy generation was heavily dependent on fossil fuelincluding coal, oil, and natural gas. If India was to achieve per capita annual energy target of 5,000 kWh by 2050, the fossil fuel based thermal power plants would be required to add a capacity of over 600 GWe in the next four decades.
“The fossil fuel fired thermal power stations are the major contributors to the emission of green house gases, especially carbon dioxide in the atmosphere,” he said.
Rapid industrialisation had resulted in the increase of concentration of green house gases. “These gases are responsible for trapping of solar radiation and thereby led to global warming.”
“For India in particular a large capacity building in fossil fuel based power stations will increase our share of global carbon dioxide emission from the present level of 5 per cent to 45 per cent. It is a matter of concern,” he said. The chairman said a significant increase in energy generation was essential keeping an eye on resource preservation and protection of environment.
He said recent developments in nano-materials look promising and could be used to address some of the environmental problems.
Mr. Banerjee said a major bottleneck in tapping solar energy it was the high cost of photovoltaic conversion. For achieving grid parity, that was cost comparable with the conventionally generated electricity, several innovative technology solutions were needed, he said.
Vice-Chancellor T.C. Shivashankara Murthy welcomed the gathering. Chief Minister D.V. Sadananda Gowda gave away honorary doctorate degrees to three persons and degrees to students.
