  • in 2013 it breaks out the box, reaching 5.6 mm in 2015
  • data derived from Aviso's viewing tool (link).

EU Renewable Energy Share

click on image to enlarge


Notes:
  • EU 16.7% renewable energy in 2015
  • note this is all energy, not just electricity
  • seems to be on track for 20% by 2020
  • this is as of 2015; why does this data take almost 15 months to be published?
  • UK is a laggard; their 2020 target is 15% not EU's 20%. And that was before Brexit!

China's coal usage in decline



Notes:

  • total energy consumed up 1.4% while GDP grew 6.7%
  • total coal consumed down 4.0%
  • coal still at 62% of electricity
  • “Energy demand has decoupled from economic activity and ... China continues to diversify away from coal faster than anyone expected,” said Tim Buckley (IEEFA)

Miscanthus v. Solar PV energy per hectare



Miscanthus:

  • 96 kWh/ha/day
  • 300,000 MJ per hectare (link) [US number, probably less in UK]
  • 42% combustion efficiency (Drax)
PV:
  • 2,974 kWh/ha/day
  • Birmingham (UK) insolation levels, 70% of global average
  • row spacing at 36.5%
  • PV panels at 17% efficiency

Peak Oil 2017?



Notes:

  • same chart as a couple of days ago (link), but with 2017 estimated demand added
  • IEA forecasts demand for 2017, but not supply

34 cm sea level rise per century?

Change in global sea level, 1992 to 2016


Notes:

  • 3.4 mm/yr = 34 mm/decade = 340 mm/100 yrs = 34 cm per 100 yrs

Another record year for utility-scale solar



Notes:

  • utility-scale is 4 MW or over 
  • cumulative utility-scale is 96 GW
  • all-solar cumulative for 2016 is forecast to be 310 GW (subject to confirmation)
  • Renew Economy article: link
  • original wiki-solar.org PDF: link
  • for context, solar generated 1.2% of global electricity in 2015. Should be 50% higher in 2016.

FAO: food prices up 17% from a year ago




Notes

  • index now higher than 2016 high
  • still down 24% from 2011 average of 230
  • mainly due to sugar? (see below)

US Wind & Solar cheaper than gas, coal and nuclear

Notes:
  • from Lazard's LCOE (levellized cost of energy) report, December 2016
  • costs are for new build
  • wind and solar shown unsubsidized (subsidized costs are even lower)
