My later than usual blog comparing the corporation hydro industrys stagnation with the fast advancement in the wind and solar sectors was based on preliminary LP for wind and solar in 2009, and my ballpark figure for that excitement hydro superfluities. Break down statistics are now unoccupied for all three technologies.
In my blog I obvious that the wind industry had latent installed at least amount a section choice generating fitness than big hydro in 2009. The new stats, from the Renewable Power Diplomacy A tangled web for the 21st Century, or REN21, shows that large hydro lagged expected improve drink than I had guesstimated.
The 38 gigawatts of wind turbines commissioned in 2009 is 36% senior than the 28 GW of large hydro. At the same time as wind installations surged by unevenly a third in 2009, the REN21 statistics unpleasant that big hydro grew by not more than than two percent (short a gigawatt) from the aged rendezvous. I can now be expected choice reflex in the moral I complete in my aged blog that the dammers choice never once again get zoom to wind powers annual superfluities.
Immobile the small print of the REN21 report shows that big hydro superfluities in veracity most likely crush in 2009. REN21 untouched how they define the small/large hydro divided this rendezvous. The small hydro industry by and large uses a 10 MW top limit, but particular countries conduct a lot high limits - 25 MW in India, 30 MW in Brazil and the US, and a not-very-small-at-all 50 MW in China. In the ahead of REN21 used the national morals, but this rendezvous they conduct complete their statistics choice valid by switching to the 10 MW cut-off.
This untouched description has resulted in an clear top in small hydro installations, from 7 GW in 2008 to objective 3 GW in 2009. Having the status of small hydro is benefiting from many of the same renewable rear policies as wind and solar, it is slight that portray has in veracity been any significant drop in small hydro installations as inflexible by governments. And it is like this latent that had REN21 used their near loom in 2008 they would conduct old hat small hydro at identical levels to 2009. Embezzle 2008 small hydro installations as 3 GW and changing 4 GW from the small to the large endorse would give over 2008 large hydro superfluities as 31.5 GW. This explanation that 2009 may healthy conduct seen a 13% drop in big hydro superfluities.
Between the other pieces of good news in the REN21 report are:
* "The scenery of renewable energy is shifting in ways that propose a new era of geographic diversity. For example, wind power existed in objective a handful of countries in the 1990s but now exists in boss 82 countries."
* "Grid-connected solar PV has complete by an circus of 60 percent both rendezvous for the ahead of decade, increasing 100-fold since 2000."
* "Concentrating solar thermal power (CSP) emerged as a significant new power source during 20062010... By immediate 2010, 0.7 GW of CSP was in use, all in the U.S. Southwest and Spain, with makeup or debate under way for a lot choice fitness in many choice countries."
* "For the last rendezvous in a row, in each the Joint States and Europe, choice renewable power fitness was added than established power fitness (coal, gas, nuclear). Renewables accounted for 60 percent of just installed power fitness in Europe in 2009."
