Oil - November update

This picture from Stuart Sandiford's blog shows "all liquids" (crude, condensate, natural gas liquids, biofuels) approximately flat for 2012.

At around 90 Mb/d, this is a lot higher than ASPO's last prediction (made in 2008) of  77.5 Mb/d (and falling).

CO2 October 2012

Here are the latest CO2 numbers from the NOAA:

• October 2012: 391 ppm
• October 2011: 389 ppm

An increase of about 0.5% per year.

UN Food Numbers - December 2012

Cereal production estimates for 2012 have been revised downwards this month by 2 million tonnes (Mt) to 2280 Mt. This is down almost 3% from last year's record but is essentially equal to the four year average.

The food price index is down 1.5% this month and is 7% lower than last year's average.

Note that at 211, the index is at more than twice the 2002-2004 average (= 100).

The next UN report is due out on February 7th 2013.

Factor of 10 energy saving by the OilDrum's efficiency expert, HereinHalifax:

I'd like to provide an example of the energy saving potential within the commercial sector, if I may: a local bicycle shop recently moved into their new location and hired an interior designer to give the store a more up-scale look. Here's what she selected for their showroom lighting:

1. Wall displays: 32 x 50-watt GU10 halogens = 1,600-watts
   
2. Recessed cans: 11 x 50-watt MR16 halogens = 550-watts
   
3. Display pendants: 3 x 100-watt A19 incandescents = 300-watts
   
4. Decorative pendants: 33 x 100-watt A19 incandescents = 3,300-watts
   

Total connected load: 5,750 watts.

And here's what we did for this client:

1. Wall displays: 32 x Philips 5.5-watt AmbientLED GU10s = 176-watts
   
2. Recessed cans: 11 x Philips 10-watt EnduraLED MR16s = 110-watts
   
3. Display pendants: 3 x Philips 12-watt EnduraLED Short Neck PAR30 = 36-watts
   
4. Decorative pendants: 33 x Philips 9.7-watt L-Prize A19s = 320-watts
   

Total connected load: 642 watts -- a near 90 per cent reduction.

Impressive. It also shows how BAU (business as usual) thinking is so far off track...

German Renewables

From Oil Drum commenter Ulenspiegel ( Permalink)

German data:

2012 around 5% of the electricity will be produced by PV, while all renewables provide around 24% of the electricity, the most important contribution (~8%) comes from wind.
Power: With 30 GW installed PV we can expect next year days with more than 20 GW PV between 1 and 4 p.m.; 2011 the highest power from renewables were > 32 GW a day in September (16 GW PV, 16 GW wind + unknown amount biomass), this meant > 45% of the power came from renewables. I hope we see more of these days in 2013 to test net stability.

Hmm, I wonder what the numbers are for the UK?

Update:
I googled 'UK electricity production 2011'  and found DECC's electricity statistics page:

• http://www.decc.gov.uk/en/content/cms/statistics/energy_stats/source/electricity/electricity.aspx

From here, I downloaded the PDF: DUKES Chapter 5: Electricity:

• http://www.decc.gov.uk/media/viewfile.ashx?filetype=4&filepath=11/stats/publications/dukes/5955-dukes-2012-chapter-5-electricity.pdf&minwidth=true

OK, here we can see that renewables were 9.4% of UK electricity (v 24% in Germany). UK wind & wave was 15.8 TWh out of a total 374 TWh, ie about 4% (v 8% in Germany). Then I found a footnote saying solar is included in wind & wave, so UK wind + wave + solar =~ 4% versus wind + solar in Germany =~ 13%.
