India squirms at “legally binding” limits of carbon emissions—shall we?

During the U.S.  Secretary of State Hillary Clinton’, visit to India last Sunday, where she heaped praises to that country’s efforts to curb carbon emissions, the local Environmental Minister Jairam Ramesh loudly thought otherwise. He said his country won’t agree to “legally binding” limits on greenhouse gases (GHG).

That remark couldn’t have come to an importune time as the minister escorted the ever graceful Clinton during the tour at ITC Green Center outside the Indian capital. She called the center “a monument to the future”, a testimony to India’s efforts towards cleaner energy sources.  Ramesh, however, pointed out that India is among the major countries which pledged recently to join the efforts to limit global warming by curbing carbon emissions.

But behind that facade of diplomatese lies a brewing conflict between the developed countries represented by the United States on one hand and the industrializing economies typified by India, over GHG emission limits.

Clinton’s smiles can easily disarm a gentleman like Ramesh, but she did not come to India to relish the splendour of Taj Majal. She was there to arm-twist India to accept her boss U.S. President Barack Obama’s cap-and trade plan as a means of weaning his country from fossil-based “dirty” energy sources like coal and oil.

Briefly, the cap-and-trade plan, which is becoming a contentious issue at par with Afghanistan at Capitol Hill, is a series of proposed legislation that makes power generation from fossil fuels more expensive by capping the amount of GHG emissions allowed from these sources. The polluting sources are only given certain emissions credits which they can trade if they have excess credits—hence the “trade” portion.

The current Obama proposal calls for an eventual 83% reduction from 2005 levels by 2050, and a do-able 14% reduction by 2020. And, yes, his bookies say that the government stands to gain $646 billion between 2012 and 2019 from the auction of carbon credits.

Obama cruised to the presidency partly riding on the promise to the American people of a cleaner future—and he is just doing that with the plan. For the American government, the plan is actually a tightrope policy of appeasing both the green movement and the coal industry which supplies roughly half of the power needs of the country. Outright banning of coal, or even a significant reduction of its use, would severely cripple the mightiest economy on earth.

American legislators know that such plan carries enormous costs, and protagonists from both sides of the divide are cranking out arguments and associated costs to support their contention. Nobody knows what the final costs would be, but one thing is sure: the American people would be facing increased electricity costs, despite the claims that money raised from the exercise could be plowed back into the economy.

To give you an idea on what electricity rates increases Americans could expect from the floated  cap and trade plan, utility operators estimate that price increases could range from a low of 40% to as high as 120% for coal-dependent states such as Oregon.

But what’s India—and the developing countries, including the Philippines—got to do with America’s internal energy policy?

Plenty.  U.S. policymakers and think tanks have already figured out, that with the increase in energy costs, the economy would come to a crawl, and the country’s competitiveness on the global arena would be acutely debased.

Which is why for the plan to be viable, the U.S. must enlist the cooperation of the fastest developing economies like India and China, by urging them to do likewise. Or using strong- arm tactics.

But India, which is growing at an average of 8% a year, cannot afford that its march to progress would be derailed by caps imposed from outside.

No, India is not running away from its commitment to cleaner future; “we are simply not in a position to take on legally binding emission targets,” Ramesh insists.

It may not be readily obvious, but people in the third world, who are consuming a fraction of energy per capita compared to their counterparts in developed economies, couldn’t simply have their angst for more power curtailed. The alternative is further slide into abject poverty.

If it were not for the associated cost, it would be pleasant to dream of fresh air every day throughout one’s life, brought about by clean sources of energy. Yes, Americans may grumble about increased electricity bills. They may have to learn to switch off their plasma TVs when not in use. Some may just bear and grin it, but somehow, other expenses will have to be pruned down. Such scenario could put more strain to people who have borne the brunt of the current recession which is considered the worst since the 1930s.

But for the millions of people in Asia and Africa, curtailing power use could mean complete darkness after dusk, or scaling down production at the micro-enterprises which could barely provide subsistence in the first place. That is, if they already have rudimentary electrical power in the first place.

Yes, mercury is still being emitted by coal plants, but will all of it finds its way to the human ecosystem?  Yes, pound for pound, a coal plant emits far more carbon dioxide than any of the alternative, albeit more costly, sources. The mightiest power on earth knows this, but it is powerless to scale down drastically its own coal usage. And for one reason: cost.

Yes, any sane person would love to dismantle all the fossil-fuel plants for the sake of a healthy future, but then, at this point in time, a major problem facing the country is still lingering poverty.

Would we buckle down and dream on, or be pragmatic like India?

Would I trade an unknown, possibly bright future, with a more horrible present?

And I thought about my country.

I just cringed.

Obama chooses Nobel laureate physicist as energy secretary

US President-elect Barack Obama announced on December 15 his choice, the Nobel Prize winning physicist Steven Chu as his energy secretary to head the Energy Department.

Chu, 60, who is currently the director of the Lawrence Berkeley National Laboratory in California, would be the first Asian-American to lead the department.

His 1985 work on laser trapping of atoms at ultra-low temperatures of a millionth degree above absolute zero, led to his being a co-winner of the Nobel Prize in physics in 1997. That seminal work, together with other techniques like magnetic cooling, laid the foundation for achieving one of the holy grails of statistical physics in 1995; the so-called Bose-Einstein condensation which demonstrates a new form of matter.

The phenomenon was predicted by none other than the great physicist Albert Einstein and then-young Indian physicist S. N. Bose in 1926. Those who achieved the goal in 1995 were awarded the Nobel Prize in 2001.

But will he make a good energy secretary?

Chu is no dyed-in-the-wool, ivory-tower type physicist. He is also one of America’s effective advocates for scientific solutions to global warming and the need for carbon-neutral renewable sources of energy. In this regard, he fits perfectly well into Obama’s green energy agenda which the latter has eloquently espoused during the heated electoral campaign. The new presidency aims for a low-carbon society by building more wind, solar, geothermal, biomass and hydro facilities.

Obama understands that crafting a viable energy policy could make or break his presidency. He also understands that the process is complex and requires the brightest minds to help him steer his energy ship to the right direction. His choice of Chu reflects the importance he gives to energy issues.

In his numerous forays around the globe, Chu has delivered a consistent message centered on “stronger storms, shrinking glaciers, prolonged droughts and rising sea levels” in apparent reference to the dire consequences of global warming.

Since assuming the directorship of Berkeley Lab in August, 2004, Chu has marshaled the Laboratory’s considerable scientific resources on energy security and global climate change, the production of new fuels and electricity from sunlight through non-food plant materials and artificial photosynthesis, energy-efficient technologies and climate science.

University of California Chancellor Robert Birgeneau who has known Chu for decades has this to say about the character of the man: “Steve Chu has been relentless about addressing the technical challenges of renewable energy in a deep way. We will now have an energy policy that can mean the U.S. will have a chance of obtaining energy self-sufficiency through new technology.”

Among other things, Chu was credited with helping establish the Joint BioEnergy Institute (JBEI), a $135 million DOE-funded bioenergy research center and the Energy Biosciences Institute (EBI), which was bankrolled by a $ 500 million grant from British Petroleum.

“Steve Chu has been an incredible visionary and true leader, particularly in the area of energy,” said Jay Keasling, who heads JBEI. “Now the country and the world will benefit from that vision and leadership."

He will be missing the ensconced academic life. But LBL’s loss will be America’s gain when the physicist-energy advocate brings his scientific talent, vision and passion for energy and the environment into the highest chambers of national energy policy.

How we wish that such inspired choice to head a very important government agency would be translated to our local situation!

Note added, December 19, 2008: The papers reported today that the powerful senate Commission on Appointments bypassed the confirmation of Department of Energy Secretary Angelo Reyes and Department of the Environment and Natural Resources (DENR) Secretary Lito Atienza along with three other cabinet members. The most vocal critics of Reyes are energy committee chairperson Senator Miriam Defensor-Santiago and Senator Jinggoy Estrada, whose father was ousted in 2001 and under which Reyes served as Army Chief of Staff. Defensor-Santiago simply said that Reyes is unfit to be an energy secretary.

Going carbon neutral

Are you carbon neutral?

In this country, if you ask the question chances are you would be met with blank stares, as if saying, what are you talking about? Or shall we change the topic? Try it.

It shows that we are still along way towards a culture of clean energy and energy efficiency.

Going carbon neutral as an individual is all about the good old, energy conservation and being energy efficient. Aside from the updated semantics, becoming carbon neutral takes on a new advocacy-- that of helping to mitigate global warming in your own small way by deliberately changing your lifestyle towards that goal.

The jury is still out whether global warming is caused more by human activities or natural events—one can argue from both ends of the political spectrum. Or whether global warming is intrinsically bad or there might even be hidden benefits to it, according to the devil advocates (For example, global warming could free up vast tracts of tundra for agriculture).

Whatever. But the incontrovertible scientific evidence does indeed point to measurable average global rise in temperatures at least since the rise of civilizations. The body of evidence ranges from paleotemperature measurements of ice cores in Antarctica to ocean currents and to migratory behavior of birds.

Let’s go back to becoming carbon neutral.

Carbon neutrality refers to energy policies and practices that effectively result in zero net emissions of greenhouse gases. Greenhouse gases are alleged to contribute significantly to global warming. Any effort to help reduce these gases will offset the effects of global warming.

Carbon neutrality works through a combination of reducing greenhouse gas emissions, researching and utilizing renewable energy resources and offsetting whatever emissions one cannot avoid producing.

There are two groups of ways to become carbon neutral. One, by reducing your own carbon emission by deliberately avoiding activities that emit carbon gases and by becoming energy efficient. And two, by offsetting what you produce by some carbon-reducing activities somewhere around the globe.

Offsetting could also mean you pay companies to maintain carbon reduction projects worldwide like tree-planting program or the use of renewable energy sources which would nullify your carbon emissions.

Large-scale offsetting is probably familiar here in the form of tradable carbon credits granted to renewable energy projects such as the Bangui Bay wind project and the methane gas electricity generation project in San Mateo. These projects have been implemented through the so-called Clean Development Mechanism (CDM) under the Kyoto Protocol. The mechanism is essentially trading an institution's excess carbon emissions with another’s surplus to lead to a net zero sums.

Offset projects can be classified into two types: avoided emissions and sequestration. The first category seeks to avoid emitting greenhouse gases by using less fossil fuel and switching to renewable sources for power generation.

The second category, sequestration offsets, involves removing an equivalent amount of CO2 from the atmosphere and storing it for a given time. Carbon sequestration proposals range from capturing the carbon dioxide emissions of coal power plants to research on how forests and grasslands management could be improved to increase soil uptake of these gases.

The voluntary offset market has developed into a major market which is triggered by increasing carbon compliance demands especially in more developed societies. Europe and Japan have been the largest buyers and China the largest seller. In 2006, the estimate of the regulated market is placed at $US21.5 billion and voluntary markets at about $US100 million for the first three quarters of 2006. The bulk of the purchases come from corporations with substantial carbon footprints that are looking to minimize their financial risks ahead of tightening regulation.

Examples of carbon offsetting projects are the following: solar power, wind power, hydroelectric power, fuel efficiency, fuel substitution (switching to a fuel which emits less carbon). Co-generation (generate electricity and heat from one source), efficient lighting (replacing incandescent lamps with compact fluorescent lamps), materials switch (replace input materials of industrial processes to one with less carbon emission), construction of green buildings (which are energy and materials efficient), green transport (use of LPG and hybrid cars), utilization of industrial waste (e.g., co-generation), biomass power generation (use of farm residue to generate power), reforestation and efficient pasture management.

Becoming carbon neutral requires a complete change in outlook aside from having the right information.

In the meantime, one can readily take the path to becoming carbon neutral by making improvements right within your home. Some of the things you could do at home include:

* Choose white goods such as freezers, washing machines and air conditioners with high efficiency ratings.

* Replace incandescent lamps with compact fluorescent lamps (CFLs) and other low energy light bulbs. Try to give up your halogen lamps.

* Switch to a power supplier which uses renewable energy if possible. At the moment this is not feasible, but this might be coming your way soon.

* Improve the insulation of your room if you have an air conditioner. Switch off air conditioner earlier; with proper insulation, coolness of the room will persist longer.

* Observe proper recycling of materials

* Don’t leave appliances and lights turned on when nobody is using

* Don't waste water.

* If appropriate, install your own renewable energy systems, such as solar panels in your home.

One could add to the list.

Becoming carbon neutral is not that difficult. Aside from having that feel-good feeling of somehow helping the environment, one can save or make money on the side.
