Stuxnet computer worm still stalling Iran’s uranium enrichment

Iran’s nuclear program reportedly struggling Network News By Glenn Kessler, Washington Post, November 22, 2010; Iran’s nuclear program has experienced serious problems, including unexplained fluctuations in the performance of the thousands of centrifuges enriching uranium, leading to a rare but temporary shutdown, international inspectors are expected to reveal Tuesday.

The International Atomic Energy Agency, the U.N. unit that monitors nuclear programs, will provide no explanation of the problems. But speculation immediately centered on the Stuxnet worm, a computer virus that some researchers say appears to have been designed specifically to target Iran’s centrifuge machines so that they spin out of control…….

Olli Heinonen, a former top IAEA official, said Monday at a meeting sponsored by the Arms Control Association that 3,772 centrifuges at the facility were being fed uranium gas and 5,084 machines were idle. “This indicates that there is a problem,” he said…..

Energy efficiency – theme for July 2019

Energy efficiency represents the single largest potential contributor to global emissions reduction, according to the International Energy Agency (IEA 2017). It should be a key part of the global energy strategy, for several reasons:

It could reduce global electric demand by more than 20 per cent, based on current rates in the U.S. power sector, while maintaining high levels of services such as heating and lighting.
It avoids the need for increased energy, capacity and grid services, making it the least expensive way to decarbonise at scale.
It can reduce carbon dioxide emissions by billions of tonnes.

A dramatic example of the power of energy efficiency is lighting. In 2017 the United States passed the milestone of 1 billion LED and CFL lights installed, avoiding 142 million tonnes a year of carbon dioxide emissions, at a cost of about $7 per ton of avoided carbon dioxide. In contrast, the cumulative installed capacity of rooftop solar reached 8,000 MW in 2017, saving 8 million tonnes a year of carbon dioxide, at a cost of $360 per ton. Lighting efficiency thus yielded almost 18 times the avoided carbon dioxide, at about 2 per cent the cost per ton of rooftop solar.

Google provides another example of the power of energy efficiency. Its data centers now use 50 per cent less energy than the average data center, according to the company. Google also developed an improved chip, the TPU, which performs 83 times better than standard CPUs. The new chip allowed Google to reduce power consumption at its data centers by a factor of 30—far exceeding the effect on Google’s carbon footprint of all of the company’s renewable energy purchases. ” – John Woolard, Eco Business, 10 June 2019
