To @new2coding: I understand there is an impact of the war on US economy...but the blueberries in question are shipped from Chile to Canada by plane directly, I doubt their price is affected by US military activities...I guess my silly example shows that fuel is still very cheap as it pays to bring blueberries from so far away (blueberries grow here locally but they are not cost or quality competitive 90% of the time)...we need price of oil to be above $200 a barrel to change consumer behavior and force governments to provide public transportation (everyone with the exception of few bikers drives here)...Kris

To @new2Coding: I think your assessment is too pessimistic, mankind will find the way to cope, and some countries like mine (Canada) will actually benefit from some warming...food production disruptions? perhaps one day but for now they seem very minor...I just bought some blueberries from Chile, $5 a pound, it still makes sense to fly them across the globe, some kiwis from New Z and figs from Morocco, these are not the special items, these are everyday and only items in Costco in Vancouver (eg you can't buy blueberries from produced in any other country etc)...and they apologized that they were out of strawberries due to some frost so I guess I food disruptions started ;-)...Yes, I support reducing power dissipation levels but we have to be realistic about it, 10% is very small in home budget (my electric bill is $43 a month, 10% of that is one specialty coffee)...Kris

The effect on individuals is probably too small to measure any signficance in dollars. The global impact is another story.

who can provide a statistical/theoretical calculation to support the 10% claim?

10% does seem like a suspiciously round number, but be that as it may I can believe that the savings would be significant. A decade or so ago it would have seemed like a silly idea to use a microprocessor (even an 8-bitter) just to hit the 'Off' switch, but these days it just might make sense. Larry M.

Colin: 10% of the power of electronic devices to be stand by power seem too high to be true. Where did you get that info from? Kris

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
