Patch-working the Grid

1

This Friday’s links highlight a few examples of global progress toward integrating cleaner energy into conventional energy grids.

The New York Times reports on the impressive bump from 17% to nearly 45% renewable-source energy in Portugal’s grid over the past five years. However, the gain in cleaner energy has come at a hefty premium for consumers- take a look at how the Portuguese are balancing it all.

Visit Australia’s Clean Energy Council website and have a look at the interactive map of all clean energy plants over 100kW in operation.

Denmark’s official website cites 12 large scale solar operations in the country that add up to 20% of annual energy demand and offer flexibility within the national grid.

Lastly, read a discussion of progress toward integration of wind energy into European energy grids on the European Wind Energy Association’s website.

NRDC Report on Climate Change, Water and Risk

The Natural Resource Defense Council (NRDC) has released a study, conducted on their behalf by Tetra Tech, which examined the effects of climate change on probable future water supply and demand in the United States. One of the main findings of the study is that one-third of the U.S. counties (> 1,100 counties) will likely face water shortages by 2050.

The full report is available as a PDF here.

The Water Supply Sustainbility Index developed by Tetra Tech for the report can be viewed interactively in Google Earth – a link to the data can be found on the NRDC’s website here. You can also turn on and off markers for which counties are top producers of different crops to get a sense of the potential impact of the water shortages. It looks like this (the green dots indicate that the county is one of the top 100 counties for producing vegetables):

The NRDC also released a one-page overview of water shortage risk and crop value in at-risk counties by state (as a PDF here). According to the overview of California’s risk due to climate change:

Percent of CA counties at risk of water shortages: 83%

Total number of CA counties at risk: 48

Total number of CA counties at extreme risk: 19

Total number of CA counties at high risk: 17

Total number of CA counties at moderate risk: 12

The value of all the crops being producing in at-risk CA counties (in $1,000s): $21,585,354
