The week in green numbers…

110 billion: The US-dollar amount Saudi Arabia intends to spend installing more than 41GW of solar over the coming two decades, including 25GW of concentrating solar power

1.8: The gigawatt amount of large-scale solar Qatar intends to install by 2020, to help meet its 30 per cent renewables target by 2030.

3.2: The gigawatt amount of solar that will be installed in the US by the end of 2012, according to GreenTech Media Research, who have predicted that America will install 1.2GW of PV in the fourth quarter of 2012.

8: The gigawatt amount that the same analysts at GTM forecast the US solar market at in 2016.

3,000: The number of solar PV panels the LIVE Community Power project intends to install on the roof of the South Melbourne Market, in Victoria, in what will be Australia’s first large-scale community solar project – 740kW – to be funded through the sale of one thousand $A1,000 shares.

99.9: The percentage of the power supply of a large electrical grid that could be provided by solar energy, wind energy and energy storage by 2030, according to research from the University of Delaware (UD) and Delaware Technical College (DTCC).

83 million: The Australian-dollar amount that the federal government said it would add to its funding for solar research and development, in an initiative supported by the US government.

169 million: The US-dollar amount that the US DoE said it would award to seven proposed offshore wind projects in six American states, to go towards engineering, site evaluation and other pre-construction work, as well as construction and operations.

92 million: The US-dollar amount that California-based solar leasing company Solar City raised in its IPO this week – 39 per cent less than initially sought – selling 11.5 million shares, equivalent to a 16 per cent stake, at $8 each.

22: The number of years since the Intergovernmental Panel on Climate Change (IPCC) – a group of the world’s top climate scientists – released its First Assessment Report, predicting global warming of about 1.1 degrees celsius between 1990 and 2030. Halfway through that projection period and the predictions are looking pretty accurate.

60 trillion: In US dollars, the ballpark amount of money under management by the world’s 1,000 largest retirement funds, insurance companies and sovereign wealth funds, many of which still do not have a climate policy, and/or have not adjusted their investment decisions as a result of climate change, according to a survey by the Asset Owners Disclosure Project.
