The Association of Energy Engineers (AEE) is proud to present the largest energy efficiency conference and technology expo held in the Pacific Northwest specifically for business, industrial, governmental, and institutional energy users.
Presented by the Association of Energy Engineers (AEE) and Hosted by National Grid, along with a powerful cross-section of cosponsors to present this industry conference and expo which addresses innovative energy management programs, distributed generation strategies, HVAC and building systems success stories, green buildings, the role of renewables, energy procurement updates, power quality solutions, and more. GLOBALCON offers more training opportunities than ever before with a multi-track conference program, intensive seminars, and an energy, power, and facility management expo.
Either labor productivity is real low in residential solar, or …
The number of solar industry jobs, now said to be 209 thousand, is widely reported and cited. President Obama included, as during his speech last April, announcing a program to train retiring military and veterans to work in solar.
The source for the number of solar jobs is an annual survey conducted by The Solar Foundation. The findings of the latest survey were published a couple of weeks ago in the "National Solar Jobs Census 2015."
December CPI up 0.7 percent, while electric rates down 1.2 percent
The Labor Department reported last week the Consumer Price Index, the CPI, for December 2015.
The CPI for all goods and services increased 0.7 percent during the twelve months through December. That's a low rate of inflation. The CPI for electricity specifically decreased 1.2 percent during the same twelve months. That's a medium rate of deflation.
Pertinent to rate design debate, variable falling further behind fixed cost
The public naturally believes that most electric utility costs are variable, if only because utility bills are mainly based on per kilowatt-hour rates. Utilities' fixed costs, for generation, transmission and distribution infrastructure, are largely invisible to the average person.
South now 57% of new house sales, Northeast/Midwest just 16%
November 2015 new house sales were 4 percent greater than the prior month and 9 percent greater than November 2014. More importantly, from the perspective of the electric utility industry, as well as the natural gas utility industry, new house sales in the South were 5 percent greater than the prior month and 19 percent greater than November 2014.
What happens in the South is crucial to the national numbers on electricity. To show why, look at the regional breakdown of electricity sales.
Produced a third of our electricity, but soon it’ll be blown away by wind
Coal has always produced the most electricity for the grid, compared to other sources, until a few recent months when coal was temporarily surpassed by natural gas. That's what the panelist said, in a seminar last week about electric utilities.
It's true that coal has led. But hydro ran neck and neck with coal well into the 1930's. And up until 1947, hydro produced over a third of the grid's electricity.
They secretly fixed light bulb life in 1924 at a thousand hours
The IEEE Spectrum article posted by Markus Krajewski of the University of Basel, Switzerland, opens like a mystery thriller (posted September 24, 2014). The secret meeting in Geneva 92 years ago still haunts how we light our world today.
All the major manufacturers of lightbulbs met to split up the world market among them. Soon enough they found a way to accelerate the market's expansion as well:
"In carefully crafting a lightbulb with a relatively short life span, the cartel thus hatched the industrial strategy now known as planned obsolescence."
