'India has no choice but to increase emissions'
By Richard Mahapatra
Given India's limited energy options, its dependence on fossil fuels and the reality of global warming, nuclear energy and hydropower are serious options for India in future, says R K Pachauri, director-general of TERI and chairperson of the UN's Intergovernmental Panel on Climate Change.
Commoditising power

Power generation is the primary contributor to greenhouse gas emissions in India. But government policy, as stated in the Electricity Act 2003, fails to address the environmental concerns arising from the unbridled burning of fossil fuels
The power plant in your backyard
By G M Pillai
In the not-too-distant future, power plants will shift from large, remote centralised stations to rooftops, basements, backyards, or nearby hill ranges.
Waste-to-energy or waste-to-pollution?
