Green Promise Seen in Switch to LED Lighting

Green Promise Seen in Switch to LED Lighting from the NY Times.

Good article, but it did not mention the LED equivalent of Moore's Law, haitz law. Each decade, LED prices have fallen by a factor of 10 while performance has grown by a factor of 20. It sounds like LED prices are falling even quicker than this, doubling about every 18 months instead of 24 months.

My translation the $35 bulb this year in 18 months will be $18, and in 3 years $9. At $9 it becomes much more attractive.

Oil Price Forcast

Oil prices could shoot beyond 2008 peak by 2012: Saudi Arabia - Interesting. So many arguments for and against it. I am surprised that oil has kept as high as it has, which is actually good for alternative energy since those that could survive at $50 a barrel oil have continued. A crash to $20 would have devastated the industry.

Mandatory use of solar heating system in India

Mandatory use of solar heating system in India.

Exciting news! From reading the article I would guess this is Solar Water Heating, but it's referring to solar PV.

Ethanol and Corn Prices

Kristof: Hidden Hunger - NY Times.

The general rise in food prices (in part because of American use of corn for ethanol) is leading to more micronutrient deficiencies.

I am not sure of this, increases in corn prices mean more corn will be planted that makes for an oversupply of corn, plus the decrease in gas has led to big financial challenges for ethanol firms.

Good article to read for the other 99% of it. Sad article.

Future Proofed Prius?

It seems since the Prius has a larger electric motor in the new version, it may be easily converted to a plug in if battery technology can be improved... Which translates as switch out the battery charger and batteries, software update, and I would guess you are set!

Prius with Solar

I view this as Toyota just adding extra junk to the Prius that is more luxury, than necessary or really adding value.
