Earth Hour 2009

Cheesy T-shirt Caption Designed for Earth Hour 2009 [Mar 28 830-930pm Local time]


Earth hour is a growing movement of people and communities trying to send a message across about the need for conservation and reducing carbon based electricity consumption. Here I discuss briefly about how one could spend that 1 hour without electricity at night, which is considered "prime time" by the television media industry. [Link to Facebook Group]

A friend of mine casually mentioned to me about Earth hour coming up and reminded me to switch off lights on Saturday. That set me thinking about trying to organize a small Earth day party, with no lights. People could wear a fluorescent T-shirt or paint messages on blank Tshirts with Fluorescent fabric paint and wear them to the Earth hour party (a party with no lights obviously!).The idea is to get people to something fun without using electricity for 1 hour.

To observe Earth hour completely, my recommendation would be turn off all non-essential electricity powered appliances. That would mean,
actually unplugging:
  • Televisions
  • Cell phone chargers and other vampire electricity suckers, if not in use. (you could do this everyday)
  • Turning off computers or atleast placing them on standby.
Other the fun things that could be done.
  1. You could go for a walk or a run
  2. Singing with your friends
  3. Try to have a candle light dinner
  4. Try to meditate
  5. Be creative

Any and all actions listed above are merely recommendations. Have fun, but always be responsible and care for your safety. Happy Earth Day.

Coal combustion residues




The 2/23 edition of C&EN had an article (subscription required) on problems associated with disposing ash generated from coal-fired power plants. Here is a link to a publication from The National Academies Press on managing coal combustion residues, which has some interesting additional background information. The article advocated that calcium sulfate/sulfide-containing wastes from flue gas desulfurization (FGD) be kept separate from the coal ash waste. Proper means of disposal in a dry, lined landfill is required to prevent leaching of the heavy metals to the environment. The scale of the problem/opportunity is shown in the above figure. What are some of the additional uses of ash, particularly fly ash and what are the challenges to their utilization?

The cement industry is the single largest consumer of fly ash. This works, because blending flyash into clinker not only is beneficial economically, but also enhances durability of the concrete. However, low-NOx regulations resulted lower firing temperatures, which result in unburnt carbon in fly ash. Cement manufacturers could co-fire high-carbon fly ash in their kilns as a component of the raw kiln feed, provided that certain precautions are taken. Additionally, research at Penn State & the University of Nottingham has focused on using the unburnt carbons in the fly ash to capture mercury emissions from power plants. Fly ash can also be used to make bricks, The Greenest Brick Company being an example.
Environmental implications of coal combustion residue handling and disposal are critical, because of the potential for heavy metal contamination and other health issues. Therefore, enhanced utilization of coal combustion residues should be one component of environmentally responsible utilization of coal.

Oil geopolitics in Central Asia & the Caucasus

Central Asia


Here is a America Abroad Media program on oil politics in former USSR republics. The program notes the tug-of-war between Western nations (NATO) and China & Russia (Shanghai Cooperation Organisation) for the region's oil & gas resources.

Historically, this region had Russian, Persian, Turkish, and Chinese political, cultural and social influences. As one of the commentators alluded to, this is a fight for the control of the center of the oil & gas-rich Eurasian landmass. As they say in chess, it is all about controlling the center.

Sinking ship? Shell exec thinks not....

Here is a link to a NPR interview with Shell Oil Company president Steve Inskeep. I am interested in the matter-of-fact manner in which CEOs and top management of both oil and utility companies imply that we as a society have to start using cleaner energy sources. I tend to agree with Mr. Inskeep that displacing millions of barrels of oil/day of imports has both of balance-of-trade, and national security implications, but do not know whether offshore drilling is the only way to achieve these goals.
