You're right about both photovoltaics and energy storage. Both of which will be discussed in future articles. Stay tuned.

Looking back is not always a predictor of the future.

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?

5 technologies are good to read. Especially the super conductor and the heat sink great achievement.

Left out here are truly significant advances in photovoltaics and electrical energy storage. probably more important than a good number of things discussed in the article.

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.

Two things: 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 only wish that were true. Unfortunately, we have stupid people here in the UK, too. Questioning the existence of global warming is not uncommon here either.

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.
