1. Unsubsidised wind and solar now cheapest form of bulk energy
That is the case in all major economies except Japan, according to BNEF. From RenewEconomy:
The latest report says the biggest news comes in the two fastest growing energy markets, China and India, where it notes that “not so long ago coal was king”. Not any more.
“In India, best-in-class solar and wind plants are now half the cost of new coal plants,” the report says, and this is despite the recent imposition of import tariffs on solar cells and modules. Continue reading Climate clippings 228
In these posts the aim is to include eight segments averaging 125 words long with sufficient detail so that casual readers can get the sense of the featured article without following the links, which are there for those interested in more detail. Lately I have been alternating week by week collections of science/observations/predictions and practical matters associated with adaptation and mitigation.
During the last week of political distractions I have had about half my usual time at the computer. Moreover some segments just won’t fit within the 125 word constraint. Next cab off the rank, I hope, will be President Obama’s climate initiative, which demands extended treatment.
So for the next little while I’ll attempt to post whatever I have to hand every Tuesday until things settle down a bit.
As usual these posts are intended to share information and ideas about climate change and hence act as an open thread. And again I do not want to spend time in comments rehashing whether human activity causes climate change.
1. Climate change measuring instruments are on life support
That’s the story from John Abraham at Climate Consensus – the 97%. He is warning that many measuring systems, especially the satellite platforms, are headed for declines in coverage, which will lead to an information deficit. His worry is that straightened budgets will not allow replacement and hence continuity of information may be broken.
In a specific example, the Tropical Atmosphere Ocean (TAO) array, which consists of 55 oceanic moorings is involved in the detection, understanding and prediction of El Niño and La Niña, is only operating at 50%. Continue reading Climate clippings 80
The weekend was a bit ordinary for me, but as supercoach Wayne Bennett says, if you can’t say anything nice say nothing. That’s how he addressed his troops after the thrashing they got in the previous week. This week they creamed the opposition!
This CC concentrates on climate mitigation, the practical stuff, rather than science, observations and future predictions. What I’m stepping around at the moment is politics, policy, opinion etc.
1. Renewables in surprising places
This image at Clean Technica indicates the potential of renewable energy. Please note that the amounts for coal etc are total reserves, whereas the renewables are annual.
I’m not sure the natural gas is accurate as there is a lot of unconventional gas around. Continue reading Climate clippings 74
