The week in green numbers – solar and ice chunks

115: The megawatt amount of solar PV that was registered across Australia in June, according to SunWiz Consulting.

70: The percentage of US citizens who now believe that the climate is changing, according to a University of Texas poll, conducted July 12-16 – up from 65 per cent in a similar poll in March. (Those saying it’s not taking place fell to 15 per cent from 22 per cent)

46: The size, in square miles, of the chunk of ice – or “ice island” – that parted from Greenland’s Petermann glacier on Monday – that’s three time the area of Sydney Harbour (or more than twice the size of Mahattan), but less than half the size of the piece that broke off in August 2010.

7.2: The tonnes per person that amounts to China’s 2011 per capita emissions – up by 9 per cent and now only a fraction lower than the EU average of 7.5 tonnes.

56.4: The percentage of the contiguous 48 US states that were in drought at the end of June, the highest percentage since December 1956, and the sixth-highest peak percentage on record.

21: The kilowatt-hours of electricity that the kinetic-power-lit sidewalk being installed at West Ham station, in London, is forecast to generate over the course of the Olympic Games.

9: The percentage of the world’s mammals that a recent survey found would not be able to keep pace with climate change.

60: The percentage of their value that carbon prices have lost since the beginning of last year, leaving them far below the €40 to €50 per tonne level many analysts believe is necessary to drive large-scale low-carbon investment.

300: The number of 6MW offshore turbines Siemens will supply for wind farm projects planned by DONG Energy for UK waters between 2014 and 2017. The two companies this week signed a framework agreement for the ‘megadeal’, which commits DONG Energy to pay a cancellation fee if the projects are cancelled.
