World must add 53GW solar PV a year to address climate change

A new report has suggested the world will need to install solar PV at an average rate of 53GW a year from 2013-2020 as it transforms its energy mix to prevent dangerous climate change.

As reported here, global investment bank Citigroup has become the latest authoritative source to warn of the high cost – economic and environmental – of inaction on climate change action, and to tally the economic benefits of shifting to low-carbon energy, transport and industrial systems.

Energy markets – as the single biggest emitter of greenhouse gases – are, of course, a big focus.
