India goes solar

Byoliveridley

India, of course, gets a lot of sun, it is wasted in the sense that it makes us sweat, causes us to use increasing amounts of electricity for air conditioning, and all in all, is a pain. So, a plan to use that sun to generate solar energy, of course, is very welcome. Solar energy use obviously is not new in India, my best friend growing up had a solar water heater at home (his family business used to make them). Policy has never kept up because there has not been a push, is this one?

The Union Government has finalised the draft for the National Solar Mission. It aims to make India a global leader in solar energy and envisages an installed solar generation capacity of 20,000 MW by 2020, of 1,00,000 MW by 2030 and of 2,00,000 MW by 2050.

The total expected funding from the government for the 30-year period will run to Rs. 85,000 crore to Rs. 105,000 crore. The requirement during the current Five Year Plan is estimated to be Rs. 5,000 crore to Rs. 6,000 crore. It will rise to between Rs. 12,000 crore and Rs. 15,000 crore during the 12th Five Year Plan.

A crore, BTW, is 10 million. India still uses its own number multiplier system for money that goes in 100s, not thousands. So, a 100,000 is a lakh, and a 100 lakhs is a crore. I never understood why this was not changed when the country went metric. Lakhs and crores, of course, are metric, but can get confusing.

The plan will start off by mandating roof top solar panels for government and government owned industry buildings in an attempt to reduce costs by scaling up. It will be followed by mandated solar water heaters for all commercial buildings and apartment complexes, and use of solar panels for all in industrial buildings. All this is supposed to happen in the next three years, which appears to be wildly ambitious.

India is a federal country with delineation of jurisdictions between the central and state governments on regulation. Electricity happens to be on the concurrent list, meaning both the state and central governments can make laws, and the central government’s laws will always preempt the states. However, building appears to be a local government issue, so managing this huge transition could get tricky. They are all supposed to use the same building code, but given the unevenness of local governance, who knows what implementation will look like.

In Phase II, starting 2012, India will go solar thermal. India and Pakistan have 200,000 sq km of the Thar Desert, a typical dry tropical desert with oodles of space and sun. It would be a good place to site all kinds of capacity similar to efforts in North Africa and Spain.

Solar thermal, if combined with the right kind of transmission and storage technology, could power the world in 7000 sq km, so theoretical capacity may not be an issue. Of course, the storage and distribution are key. Molten salt batteries look very promising for solar energy storage and night use.

India’s electricity needs are daunting. This WolframAlpha search provides the following:

IndiaCanada

Note to Wolfram: your data presentation would result in a failing grade on a middle school term paper, where are the sources? Where did you get your numbers? BIG FAIL!

We in Canada use more electricity than India for about a billion fewer people. Clearly, if India was as profligate as Canada in energy consumption and got the power it needed to get there from coal, we would all be dead soon. India needs to go solar in a hurry and I am glad the government has released a policy that is more ambitious than the US or Canada. It needs the support and funding to make it happen and I for one will be very happy to see progress in this area. Solar power needs big up front costs and little ongoing costs.

Can Indian industry provide the money needed? We shall see. I am not too worried about the photovoltaic panel parts, they will muddle along in typical patchwork Indian fashion with the quality of governance being the controlling factor in success or failure. It is the capital and political will needed for solar thermal that strikes me as problematic. The coal and mining industries are entrenched in some population (and vote) rich states like Bihar based in the central and north east regions and there could be some big losers if India went away from coal (as it needs to in order to prevent catastrophic climate change) and toward solar thermal, which I assume would come out of Rajasthan (West).

Anyway, we live in interesting and sunshiny times, stay tuned for more.

Green Building in India: NOT

Byoliveridley

There is a buzz about green buildings. But the question is: what does one mean by building green? And how does one design policies to make the green homes of our dreams?Green is not about first building structures using lots of material and energy, and then fixing them so that they become a little more efficient. Building green is about optimizing on the local ecology, using local material as far as possible and, most importantly, building to cut the power, water and material requirements.

via Green buildings: how to redesign | Centre for Science and Environment.

Sunita Narain makes some excellent points about building in India, and how western architecture influenced glass facades, closed buildings, etc. make little sense in India, and how traditional building concepts, optimised for local conditions would make more sense.

Two points:

  1. Traditional buildings are not necessarily optimised for density. To fit a lot of people in a little space, you need to build up. No, not 100s of stories, but fives and tens? It would be interesting to figure out that contradiction. But I’m no architect and I don’t know the answer
  2. The glass facade concrete skyscraper jungle look is associated with aspirational prosperity, ask any affluent Indian what they like about Hong Kong, or New York, or Singapore, and the shiny buildings will figure pretty high on the list after cleanliness and shopping. This is the kind of building associated with modernity and “class”. Making a sealed glass and concrete hell hole work in regions of high heat and humidity without large amounts of energy use for air conditioning is difficult.

It appears, though, that at least some people are thinking about this, as this book, helpfully titled Tropical Sustainable Architecture, would attest to.

BTW,
Sunita Narain’s editorials for the Down to Earth magazine are always thoughtful, and required reading for anyone interested in India’s development and environmental issues.

Turtles, Arribadas, Science, Policy and Implementation

Byoliveridley

turtle Read stuff like this (hat tip to my mom for telling me about this report she’d seen on TV in Madras), and you begin to doubt your utility as a scientist.
IBNLive : Orissa turtles neck-deep in danger

Nearly 3,000 Olive Ridley turtles have died off the Orissa coast this season. Beaches have become turtle graveyards.

Orissa is one of the three places in the world where the Olive Ridleys come for their annual mass nesting.

Mechanised trawlers are the biggest culprits for this slaughter. When the trawlers go to the sea, turtles are trapped in their fishing nets. The turtles are unable to disentangle themselves and suffocate to death.

See the video report too. In her own breathlessly indignant style, the reporter explains the science behind turtle excluder devices (well known and established), the regulation expressely forbidding shrimp trawling close to the coast, especially during the arribada, the money set aside in the budget to purchase a few speed boats for the coast guard, who are well aware of the problem, so wot’s, uh, the deal?

The investigative reports contradict each other, the first one linked said there was no patrolling, the second one gushingly praises the coast guard for vigorous enforcement and patrolling, so which is it? I need to find out, call on some old friends… But clearly, there are issues if net catch mortality is on the rise.

The three pillars of any regulatory action are the science, the policy, and the implementation. The science here is very clear (though the US administration seems to not think so any more?), shrimp nets with turtle excluder devices cause decrease in mortality. The policy is clear, use these nets when shrimp fishing, and completely ban fishing activity during the arribada (the number of turtles in an arribada, 50000 in a night and perhaps 300000-400000 over the course of a week is staggeringly large, so, shrimp net or not, you’ll kill a lot of turtles just by being there).

So, like anything else in India, where is the implementation? The people running the trawlers know they are illegal anyway, so they don’t bother with the TEDs. The owners of the trawling boats never face the consequences, only the poor hapless fishermen running the boats. No attempt is made to coopt the people being regulated, it is a top down “we tell you what to do” kind of situation where the law is selectively enforced, no explanations are given, the regulation may just be an excuse to get some kickbacks. The fishermen see the excluder device as an inconvenience as they are not shown how to use it. Some low level bureaucrat in charge of buying high speed boats for the state’s forest service either does not realize the importance of getting this policy on the road, or is on the take. You can pick any, or all of these reasons and you’ll see why just like most other things in India, the road to hell is paved with good intentions 🙁

Why be a scientist and come up with cool new techniques to do things when you don’t pay equal attention to the implementation of techniques invented 20 years back? As a responsible scientist, I must look at policy and implentation with as much interest and passion as I look at the science – New career paths?

Obama seeks U.S. carbon emissions cap

Byoliveridley

President Barack Obama on Tuesday called on Congress to send him legislation that places a market-based cap on U.S. carbon polluting emissions and pushes the production of more renewable energy.

In his first speech to a joint session of Congress, Obama said that “to truly transform our economy, protect our security, and save our planet from the ravages of climate change, we need to ultimately make clean, renewable energy the profitable kind of energy.

Good, Canada will have to harmonize. Stephen Harper was last seen pretending that his “intensity based”” approach was just a “different” way of measuring emissions. You can say that speed and distance are just two ways of measuring travel!

It is still early and we will see what the US congress can come up with, and what egregious exemptions and offsets it will provide for. Lobbying is already fast and furious. But the news emanating from Obama is promising on the climate change front.

The NYTimes Covers Cricket!

A Battle of National Pride, Fought on the Cricket Field – New York Times

On Sunday, an umpire presiding at a high-profile game between England and Pakistan ruled that in his belief, Pakistani players had been tampering with the ball, and he told Pakistani players of his suspicion, awarding England five bonus runs, or points. Cricketers consider ball tampering to be one of the most heinous forms of cheating. By way of protest, the Pakistanis refused to leave their dressing room after a scheduled break for tea. The umpire, Darrell Hair of Australia, a person known for contentious rulings against some Asian teams, then removed the bails — little wooden bits that fit horizontally across the top of the larger wooden stakes called stumps — denoting that Pakistan had forfeited the game. The Pakistani team, nonetheless, walked back onto the field. But by that time the umpires had walked off, having ruled that Pakistan’s no-show constituted a terminal offense. Game to England — the first time in 129 years of so-called Test matches between national teams that a game had been forfeited in this way.

Oh well, to explain this to someone who does not watch cricket requires a long dissertation on swing and “reverse swing” (check out this video from the Beeb, this page and wikipedia). When the ball is “new” and shiny, the ball moves laterally in the air a certain way, thanks mostly to the bowler’s skillful application of the physics of air flow around a spherical object (and spit). He keeps one side shinier than the other so that the air resistance around the rough side pushes the ball in the direction of the “rough” side. The angle of the “seam”, or the ball’s stitching also helps maintain the difference in flow velocity. Weather conditions also play a big part, it tends to swing more when it is a little cold and humid. When the ball gets older (cricket uses the same ball till it gets too worn out), the “rough” side is now so rough that the airflow around this side now has less resistance, and the ball “reverses” its swing.

So what does all this have to do with what happened on the field? Well, you’re allowed to keep one side smooth with spit and polish (well, mostly spit, because polish is not allowed!). But, you’re not allowed to artificially roughen the other side to make the ball reverse swing quicker than it normally would. The Pakistan team pretty much perfected reverse swing, and have been caught tampering before. Hair looked at the ball, decided unilaterally that the ball had been tampered with, penalized the team and expected the Pakistan team to just accept his decision and play.

This particular umpire has a long history of controversy with Asian teams, I remember his first game very well, it was a test match in 1992 between Australia and India where his decisions pretty much pushed the game in Australia’s favor (this was before “neutral” or other country umpires). I was pissed off then, and his decision making has always been suspicious. He has called a Sri Lankan bowler for “throwing” when he wasn’t supposed to. I hope he never officiates another test match involving India, Pakistan or Sri Lanka ever again, his judgment is to be considered suspect!

CNN.com – Caribbean coral suffers record die-off – Mar 31, 2006

Byoliveridley

More from the global warming drumbeat, which has by now reached tipping point proportions. I was trying a few months back to predict when global warming would become a “story” in this country, something to be reported on, rather than a “debate”, I guessed middle of the year, well, I think it arrived in March with Time and Newsweek covers, and personally with at least two friends asking me about it. News coverage of climate change has changed completely in the last few months as observations catch up with the modeling, as they do most of the time. But  people like to see proof, not model simulations which can always be explained away, well, here’s more proof…

CNN.com – Caribbean coral suffers record die-off – Mar 31, 2006
The Caribbean is actually better off than areas of the Indian and Pacific ocean where mortality rates — mostly from warming waters — have been in the 90 percent range in past years, said Tom Goreau of the Global Coral Reef Alliance. Goreau called what’s happening worldwide “an underwater holocaust.”

And with global warming, scientists are pessimistic about the future of coral reefs.

“The prognosis is not good,” said biochemistry professor M. James Crabbe of the University of Luton near London. In early April, he will investigate coral reef mortality in Jamaica. “If you want to see a coral reef, go now, because they just won’t survive in their current state.”

For the Caribbean, it all started with hot sea temperatures, first in Panama in the spring and early summer, and it got worse from there.

New NOAA sea surface temperature figures show the sustained heating in the Caribbean last summer and fall was by far the worst in 21 years of satellite monitoring, Eakin said.

“The 2005 event is bigger than all the previous 20 years combined,” he said.

What happened in the Caribbean would be the equivalent of every city in the United States recording a record high temperature at the same time, Eakin said. And it remained hot for weeks, even months, stressing the coral.
