2015 is just about gone. It was a pretty sad year for the world. But I will focus on what we achieved in the
year.
Natural gas was a green spot on the planet. Yes CH4 not Gore lowered carbon emissions by
reducing coal use substantially in the USA and marginally in China. Solar PV of the silicon variety again did a
decent job as did wind power. These two
are the best options for renewable energy.
Concentrated solar and bio fuels were a total bust as was CIGS in PV.
On the demand side LEDs did their wonders and more efficient
ICE vehicles also hit the road. Low
gasoline prices moderated the improvement in the CAFÉ average but it is
trending up and low gasoline prices are not permanent. The move to using pad computers and smart
phones and away from desktops and even laptops also continued and these smaller
devices use far less energy. Data
centers now operate at far higher temperatures and have cut energy use
significantly even though the quantity of data circling the planet expanded
exponentially.
Paper use decreased again and fewer trees are becoming
newsprint and paper for printers. That
folks now read the news on a pad or smart phone has done the world a very good
deed. Toilet paper production certainly
increased because of population explosion and increased disposable income. We know entropy always increases and “shift
happens”. Not the F in shift.
The biggest problem facing the planet is water. Worldwide use of fresh water is increasing
and rainfall is not. Fresh water has
been supplied by solar power since plants first stepped on the earth, but now
more and more desalination plants that use grid power are springing up. Get the pun “springing up”. I intend to become more knowledgeable on
water and will then opine further on H2O in 2016.
I wish you all a happy new year and let’s hope 2016 is
safer, greener, and healthier than 2015.
