Twelve times more solar needed to avoid climate catastrophe: IRENA.

PV Tech: “Solar deployment needs to increase 12 times over by 2030 to avoid “climate catastrophe”, a report by the International Renewable Energy Agency (IRENA) has warned.”
“Launched in New York last week, the report, ‘REmap 2013’, aims to show a 36% share of renewables in the energy mix by 2030 is feasible, affordable and will mitigate climate change risks – keeping carbon pollution below 450ppm to keep within a ‘safe’ 2 degrees Celsius rise in global temperatures.
Based on the IRENA model, wind energy needs to increase the most, by a factor of 15, and solar second, by a factor of 12. Geothermal needs to grow nine times over, hydro to double, biomass by a factor of 1.5 and tidal generation to increase by less than 0.1.
IRENA has calculated the switch to renewables also provides US$740 billion of savings each year on environmental costs from burning fossil fuels – cancelling out the investments costs required to reach 36% renewables.
Out of the US$750 billion, US$200 billion could be saved in health costs, while 900,000 clean energy jobs would be created, IRENA said.
The REmap show by 2030 there would be a 15% decline in oil and natural gas, and 26% decline in coal, helping countries that import fossil fuels to be energy secure and to reduce air pollution.
The REmap is based on the energy demand and consumption of 26 countries, or 75% of global energy consumption.
….The key to deploying enough renewables quick enough said Gielen, is to focus on five points: “planning realistic but ambitious transition pathways; creating enabling business environments; managing knowledge of technology options and their deployment; ensuring smooth integration of renewables into the existing infrastructure; and unleashing innovation.”
….The IPCC draft recommendation also said renewable energy has the potential to more than meet global energy demand, as renewables are now the third largest contributor to global energy supply – just behind coal and gas – with a good chance of being the second largest contributor by 2020. Since 2005 solar has increased deployment by a factor of 25, the report states.”
