Cool way to cool the globe


IS this a whacky way to cool the globe? It doesn't seem so.

DESPITE growing interest in clean energy technology, it looks as if we are not going to reduce emissions of carbon dioxide anytime soon. The amount in the atmosphere today exceeds the most pessimistic forecasts made just a few years ago, and it is increasing faster than anybody had foreseen.

Henning Wagenbreth

Even if we could stop adding to greenhouse gases tomorrow, the earth would continue warming for decades — and remain hot for centuries. We would still face the threat of water from melting glaciers lapping at our doorsteps.

What can be done? One idea is to counteract warming by tossing small particles into the stratosphere (above where jets fly). This strategy may sound far-fetched, but it has the potential to cool the earth within months.

Mount Pinatubo, a volcano in the Philippines that erupted in 1991, showed how it works. The eruption resulted in sulfate particles in the stratosphere that reflected the sun’s rays back to space, and as a consequence the earth briefly cooled.

Or we can also shoot missiles with the appropriate payload.

GMA ecstatic over wrong things, says former Clinton aide

Joseph Romm, assistant secretary for energy efficiency and renewable energy during the Clinton administration, was unhappy with the remarks of GMA during her recent appearance in a forum of Clinton's Global Initiative. In his post "Why sustainable development is so damn hard, Philippine edition". he quotes the president:

Yesterday, I also announced, for the second time, an initiative where we are encouraging economic zones to be set up around the geothermal sites, because not only can geothermal fields give us power, they also give us jobs because the local governments earn royalties from the geothermal power. And they, by law, they can only use most of it for electricity. So they subsidize the electric bills of the constituents. So now we are creating economic zones there, so that businesses, like electronics, for instance, power incentive electronics firms, will locate there. So aside from the subsidized power bills from the local governments, they will also have the usual investment incentives. So these areas, which are usually far from central Manila, will now have industries, as well as power."
At first I thought she did not have the law right, as I was thinking about provisions in the energy department's regulation (1-94) which does not really impose power rate subsidies in the use of the funds generated, see the power sector reform tracker.

The Generation Company and/or energy resource developer sets aside one centavo per kilowatt-hour (P 0.01/kWh) of the total electricity sales as financial benefit of the host communities of such generation facility, where applicable. The financial benefits are given directly to the host LGU or region, especially to the community and people affected while equitable preferential benefits are being provided to the host region. The accruals of the financial benefits are allocated for the following:

    1. Electrification Fund (EF);
    2. Development and Livelihood Fund (DLF); and
    3. Reforestation, Watershed Management, Health and/or Environment Enhancement Fund (RWMHEEF).
This is actually the pertinent provision GMA was referring to, in section 294 of the Philippine Local Government Code (RA 7160), which reads:
Development and Livelihood Projects. - The proceeds from the share of local government units pursuant to this chapter shall be appropriated by their respective sanggunian to finance local government and livelihood projects: Provided, however, That at least eighty percent (80%) of the proceeds derived from the development and utilization of hydrothermal. geothermal, and other sources of energy shall be applied solely to lower the cost of electricity in the local government unit where such a source of energy is located.

On a more positive note, the system of subsidies and cross-subsidies in the Philippine power sector has been reformed a great deal since the passage of the EPIRA. For one, most of the inter-grid (among the three major island groups Luzon, Visayas, and Mindanao) and inter-class (between industrial/commercial and residential) subsidies have been virtually eliminated. What remain are the intra-class subsidies in the residential sector with the ‘institutionalization’ of ‘lifeline’ rates supposed to be for the poorest among the poor in all the franchise areas.

The new system of lifeline rates is much better than the old one, where each franchise area had almost complete leeway over them, but still is not good enough. For instance, in the Meralco area, households consuming up to 100 kilowatt-hours a month are subsidized even though this threshold is way above what poor households consume on average (as determined by the official povety count). Historically there are two possible motivations for such lifeline rates.

The more compelling is the notion that the poorest households underconsume electricity because they don’t consider the positive effects on the children’s education and their own access to media and social connectivity have on the rest of society, coupled with unwarranted coupling because of limited possibilities for pleasure at night.

The other is with society’s desire to work toward equality of opportunities and incomes/outcomes. Most economists agree that this objective could be pursued much better through outright cash handouts rather than subsidies for specific goods.

What alarms me in the Philippine context is the ‘populist’ attempt by the current administration to work for the granting of special electricity rates to many special zones, defeating the purpose of the power sector reform act. It is in this light that GMA’s announcement must be viewed. She had no hand in the enactment of the local government code but instead of working to revise the pertinent provisions, it panders to some special interests. Note that the subsidized rates are based on a fixed total to use for subsidization and would have the effect of raising residential rates in the affected communities. In my own estimation, greater industrial activity would lead to more pollution. While the increase might not be that much in the overall inventory, it is the intent and the pandering to special interests which is worrying.

Being clear on going nuclear

I would not worry too much about reported plans by the energy department, with the imprimatur of the president, to 'study the possibility' of harnessing nuclear power in the country. There is no lack of things to worry about in this world, and there is no dearth of interesting subjects to study either. For all I care, Secretary Reyes can study nuclear physics and rocket science, but on unofficial time. I will start worrying when he gets distracted from the more important tasks of introducing real competition and lowering rates in the power sector and achieving the goals of the rural electrification program.
While I keep an open mind on nuclear power, especially as a potential solution to the risks of global warming, this is a non-starter for the Philippines, where the justifiable knee-jerk rejection of nuclear power is informed by the intertwined issues of corruption and safety.
It came to pass without much ado that the foreign debt of more than $ 2 billion incurred under clearly fraudulent conditions for the Bataan nuclear plant was finally fully paid in April this year. While many in legal circles felt we had a strong case against the Marcos henchman Disini and the supplier, Westinghouse, the Aquino administration had opted to settle out of court with the latter for a meager $25 million worth of old turbines. I don't know what happened to Disini. The Aquino administration also opted to honor the obligation but transferred it from the books of the National Power Corporation to the national account. (Just think how much higher NPC rates would have been if the white elephant had been part of utility's rate base. To its credit, NPC has at least managed to generate some income from the Morong complex by operating a hotel and cabanas---respectable houses meant for the power plant staff--- open to the public for conferences and private breaks. I've tried fishing by the wharf there and snagged some poisonous fish--- no not from any nuclear contamination because no fuel rods were ever stored there. There is also a good firing range for target shooting). Aquino officials shuddered at the thought of triggering cross-default provisions, used to shield banks from the consequences of their bad decisions---sound familiar?---- and lengthy litigation, had they chosen a more militant stance.
That same fear also probably was behind the attitude of the committee tasked to review the contracts with the independent power producers. From the very beginning, it chose a non-confrontational stance. But I've digressed enough.
Perhaps, Secretary Angelo Reyes was misquoted in this reportage on his view that nuclear power would help decrease power rates. A recent Economist article argues this hope rests on shaky ground. I'm all for nuclear power, but for Vietnam, Indonesia, and Thailand. Let them, as long as that decision has popular consent. On safety and sustainability, he can be guided by this real expert. Also, what to do with spent fuel and the risks of nuclear proliferation remain unresolved.
Notwithstanding Three-Mile Island, Chernobyl, and the fears evoked by current difficulties in that Japan nuclear plant undergoing repair after an earthquake, many risk assessment experts would probably tell you that Filipinos living around a nuclear plant would have a greater chance of dying from a motor accident (getting hit by a tricycle?), a fall resulting from a carelessly thrown banana peel, or from the bullets of political hitmen than from a nuclear plant failure. But subjective risk perceptions are always part of objective reality and that is where the main problem is. Moreover, it will probably take us at least fifty years to resolve the issue of safety in this country, where many controversies one hopes could be resolved by hard science never seem to be. (For lack of resources and intellectual boldness, neither the department of energy nor of science and technology could even come to a simple judgment on some alleged fuel-saving automotive gadgets that a former environment secretary had installed in his department's vehicles).
But what is there to study anyway? The energy secretary must of course appreciate that we are not at the forefront of nuclear research and would thus have to depend on technological advances from abroad. He wants a technical pool? For what and at whose expense? Most of the people sent by NPC to train for nuclear plant operations opted to remain in the United States, and my acquaintances who came back formed part of NPC's brain trust, mainly in desk jobs in planning and in environmental work, and are now in the private sector after the utility's downsizing.
As far as I know there is no legal prohibition against putting up a nuclear plant in the country, but the proponent would have to pass the difficult environmental and social hurdles. Identifying potential sites? Okay. We can always let local governments with suitable sites volunteer and take care of the problem of social consent. Cebu? Just kidding. Unless of course one option under study is for government to get back into the business of generation, which some would consider foolish.
Finally, on climate change, we should not worry about that too much either, not in the sense of spending our meager resources. Our climate change policy should be anchored on the fact that historically and currently, we are a very minor source of so-called greenhouse gases. To the extent that we are almost certain to suffer from hotter average temperatures, our national policy should be one of seeking justice and compensation from the culprits, the developed countries responsible for the accumulation of these gases. We should adopt policies encouraging less GHG emissions, sure, but not at the expense of the poor and more important priorities. For one, we can tax, to the extent possible, the energy consumption of the rich.
Okay, let's be open, and just leave it at that.
