Good point, but combined with other energy saving developments (such as the CoolChip heat sink for data centers mentioned in the sidebar, etc.) that are increasingly a focus in new system design, then it is likely/probable that energy consumption may/will decline. It's about what your priorities are in future designs. Among the criteria needs to be "energy efficiency."
It's up to engineers to make energy efficiency a high priority don't you think?
Gallium Nitride (GaN) technology is also expected to replace conventional Silicon in thousands of Apps. Moreover, GaN is outperforming SiC in terms of cost and performance. SiC will probably be cornered to high power regime, as GaN is still in infancy in that domain.
1. Show me those solid state (LED) light bulbs first. The technology is making a progress but the use of hi-power LEDs is limited to industrial use as for now. All the bulb replacements that you could use at home are just crap. The colour is bad and the efficiency is NOT better than CFLs. CFLs also went a long way so the colours became acceptable and actually I like them more than traditional bulbs (the average power used in my home for lighting at night is 100W max with CFLs all around).
2. Whenever I read about power lines and green energy the thing that always comes up is: this cable / wind turbine can power 300000 homes. As engineers we should avoid such statements because there's no definition of what the house power consumption is. From your article (570MW and 300khomes) it seems that the max power is around 1.9kW. It will strongly depend on the country (and the type of energy you use for heating and cooking).
I had a vacuum tube computer during the ice age. But confound it, even with all these new low-powered gizmos my electricity bill still keeps going up!
Seriously, technology breeds the use of technology (say "i" this and "i" that). We're addicted to proliferating our collection and use of devices. And the market pushes us to want more talk/text/game and Facebook time--this is what's driving low-power products.
The unintended consequence is that we're ending up using more, not less power--bellying up to the all-you-can-use electronics buffet. Don't get me wrong, I'm all for the "green" movement. But the reality is that our efforts to lower power use will be corrupted by markeitng programs that promote more "minutes".
To solve the world's "energy crisis" (debatable topic) we'll have to stop giving lip service to alternative paths and commit massive investments to it. To contribute to the solution, we all need to go to mobile rehab.
BTW, do you think all those vacuum tube computers caused the end of the ice age?
I'm sure not one of these climate change deniers is a climate scientist.
You can be aggressive and abrasive as you want, you might even succeed in bullying the weak-minded into acquiescing to your baseless rants, but the science is out there.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
