Climate change: positive messages on the international scene

By Dr Flora Whitmarsh, Grantham Institute

This blog forms part of a series addressing some of the criticisms often levelled against efforts to mitigate climate change.

The Twentieth Session of the Conference of the Parties (COP 20) – the latest in a series of meetings of the decision making body of the UN Framework Convention on Climate Change –began in Lima this week. Many in the media are quick to point to the difficulty of obtaining international agreement on greenhouse gas emissions reductions, and to denounce COP 15, which took place in Copenhagen in 2009, as a failure.

Why subsidise renewable energy?

by Ajay Gambhir, Grantham Institute

This blog forms part of a series addressing some of the criticisms often levelled against efforts to mitigate climate change.

It is often claimed that intermittent renewable sources of electricity (mainly wind and solar photovoltaics), are too expensive, inefficient and unreliable and that we shouldn’t subsidise them.

What are the facts?

Last year, governments spent about $550 billion of public money on subsidies for fossil fuels, almost twice as much as in 2009 and about five times as much as they spent subsidising renewables (IEA, World Energy Outlook 2014). This despite a G20 pledge in 2009 to “phase out and rationalize over the medium term inefficient fossil fuel subsidies” that “encourage wasteful consumption, reduce our energy security, impede investment in clean energy sources and undermine efforts to deal with the threat of climate change”.
