Breaking Bread with Lost Sheep

By Energy Rant No Comments
10 While Jesus was having dinner at Matthew’s house, many tax collectors and sinners came and ate with him and his disciples. 11 When the Pharisees saw this, they asked his disciples, “Why does your teacher eat with tax collectors and sinners?” 12 On hearing this, Jesus said, “It is not the healthy who need a doctor, but the sick.” – Mathew 9:10-12. I was lost in the wilderness in search of inspiration for another post when Jesus came to mind. So I thought, “Jesus ate with sinners. I’ll look that up and see what I find.” What I found…

Dodging the Absurd

By Energy Efficiency, Energy Rant No Comments
In Stalin Lives, I mentioned our plan for securing an ENERGY STAR® clothes washer and dryer for our house.  What I did not mention was that the local appliance stores do not even stock gas-heated dryers. Think about how stupid it is to generate electricity with maybe 35% thermal efficiency, lose 10% of it to line losses, as discussed last week, in it’s transport to the home and then use this high-value energy as a toaster coil to dry clothes.  We, as well as I am sure millions of households, use “gas”, natural gas in our case and propane in…

Taking on Parmenides

By Energy Efficiency, Energy Rant One Comment
We do a LOT of energy efficiency program evaluation and measurement and verification work all over the country; make that North America.  Program evaluation consists primarily of process evaluation (process) and impact evaluation (impact).  Our work is almost entirely in the impact side and I know just enough to talk dangerously about process. Impact is the analysis of what energy savings are really attributable to the program.  This includes verifying the physical installation and determining the actual savings using some sort of engineering analysis.  This actual savings is known as gross savings in the business.  It also includes determining whether…

Soothsayer: Analyze This

By Energy Efficiency, Energy Rant, Renewable Energy, Sustainability No Comments
How many times have you read "we can create 40 million jobs and reduce our energy consumption by 90% if only we did x, y, and z."  Lester in this article says by 2035 we can double our fuel economy.  Well I should hope so!  Lester is actually one guy that is conservative in his estimates/goals.  David Goldstein in the same article says we can decrease our energy consumption by 88% by 2050.  Now where does he or any other egghead come up with these numbers? I had to laugh out loud regarding the results of an energy efficiency potential…

From Jack Wagon to Hobo

By Energy Efficiency, Energy Rant, Sustainability No Comments
A couple weeks ago, the National Academy of Sciences released a study that summarized the findings of the general public’s perceptions of energy consumption and potential savings from various end-uses in their daily lives.  You can check out the curves in the linked article above and take my word for it or risk brain damage reading the thing.  To me there are several significant findings, none of which surprise me.  These are in no particular order and are only a subset of the findings. Finding #1 – When asked open ended questions about ways to save energy, people overwhelmingly selected…

All things energy. That’s our jam.

We talk a lot about energy – from the serious to the satirical.
