Ethanol – Where Physics, Politics, and Emission Limits Collide

By Energy Rant One Comment
I recently researched many attributes and market effects for liquid fuels for a project we are working on, and like my digging into the wind and climate studies, this research results in several findings. This post covers ethanol and gasoline blends. A future post will cover fuel cost and impacts on electric vehicles and utilities. My journey began with the ethanol market. We produce a lot of corn-derived ethanol here in the northern plains. By 2020 there may be a big demand for Midwest ethanol as California caps the carbon intensity of its liquid fuels. The cap, part of their…

Question: Carbon and Benefits? Answer: Efficiency

By Energy Rant 3 Comments
“Don’t drink the Kool-Aid” and being as objective as possible are how I roll. If you feel otherwise, by all means, let me know. Driving across Southern Minnesota recently, a billboard like the image nearby caught my eye. I thought this would be worth looking into to see what they have to say. As I expected, the paper it promotes is jaded against wind energy. But what arguments do they make? Are they legitimate? Wind is Fuel When thinking about wind-driven power generation, it has a lot of hurdles to overcome to be cost-effective. One near the top of the…

Untold Story of Disappearing Energy Jobs

By Energy Rant No Comments
On the subject of electricity generation sources and price, I’ve been reading numerous articles from various bona fide sources and started connecting dots. Public Utilities Fortnightly (PUF) has written about historically low electricity prices, as a percent of GDP or household spending, numerous times in the past year. Electricity price escalation has not kept pace with the consumer price index. As of last August, Steve Mitnick, of PUF shared data, which I plotted on the chart below.A year ago, I wrote about this topic as well in Low Electricity Prices - For How Long?. In that post, I explained how…

Why Energy Efficiency? – Five Findings

By Energy Rant No Comments
This year ACEEE published a three-part series on why people and companies invest in energy efficiency. First, they provide some guesstimates of energy efficiency investment in the United States. Their researched estimates vary from $60 billion to about $120 billion, annually. Is this a reasonable guesstimate? According to their State Scorecard, program spending on natural gas and electric demand-side management programs held steady at about $7.5 billion in 2016. Check. The International Energy Agency pegs worldwide investment at $231 billion and about $40 billion in the U.S. Check. As a laugh test, $100 billion is a measly 0.5% of the…

Energy Efficiency in a Land of Renewable Foie Gras

By Energy Rant No Comments
A couple weeks ago in Renewable Energy, Bad Parents, and Strawberries, I wrote that the value of an electrical generating resource depends a little on how cheaply it can produce energy (kWh), but a LOT on when and the (new word alert) dispatchability of the resource. For instance, California already has so much solar generation at the wrong time of day that it needs to dump kWh by paying producers to quit. This is demand response in reverse, or (new term alert) supply response. Yes, they are curtailing less than 1% of sales, but they are also two years ahead…

Renewable Energy, Bad Parents, and Midwest Strawberries

By Energy Rant 2 Comments
If you enjoyed the greatest modern decade of sports, when MJ went six for six in the NBA finals, you would remember this McDonald’s commercial nearby. In it, Larry challenges Michael to a game of trick shots for Michael’s Big Mac and Fries. (I don’t know why my adolescent idol, MJ, would agree to play for something he already paid for, but…) As you can see, the game quickly progresses into an outlandish game of “first to miss, loses.” It leaves off with a shot from the top of Chicago’s fourth tallest building, the Hancock Tower. Cost of Electricity I…

Reverse Diversification Coming to a Utility Near You

By Energy Rant One Comment
In my Personal Finance class as an undergraduate, our instructor used the term diworsification for large stalwart companies. Diworsification occurs when a company buys another company it knows nothing about and isn’t complimentary to the core business. Utilities got into this in the wild west days of 1990s deregulation, buying telecommunication and even real estate companies. That didn’t end well, and they went back to their core business of the regulated monopoly.In recent years we have experienced a reverse diversification of our power supply – namely in the reliable, conventional, thermal power plant sector. We still get almost half our…

Things You Need to Know Re Electric Vehicles

By Energy Rant 2 Comments
Last week I wrote about understanding the customer and knowing what they want, whether the customer is the utility, regulator, or the end user of energy. Taking this a step beyond, the customer/client may not know what they want. For example, a hypothetical customer may want to control all energy use in their house from a smartphone, 100% renewable energy, and a smart-grid connected electric car. I am convinced once the hoopla settles, customers will want (1) cheap, reliable energy, and (2) any help to be more successful. Three weeks ago, I wrote about Messing with Near Perfection. That post…

Distributed Energy Resources – Messing with Near Perfection

By Energy Rant One Comment
A couple years ago at an AESP conference, we had a fascinating speaker and topic. It was one of those that had me thinking deeply and philosophically. The subject was technology and the future. The takeaway: every problem is either a technical problem or one of human flaw. As for technical problems, there is nothing short of violating the laws of physics, including the second law of thermodynamics, that humans can’t and won’t someday solve: cancer, heart disease, failed or destroyed body parts, and of course, energy, and even aging. As we say at Michaels, (although we are not yet…

Utility Scale vs Small Distributed Generation – Protection by Savage Suffolks

By Energy Rant No Comments
The June issue of Public Utilities Fortnightly (PUF) featured a supplemental, special report in collaboration with Navigant Research. One of the interesting articles in that publication is Impacts, Threats, Opportunities of renewable energy production. It compares utility scale to distributed renewable power generation. To refresh your memory, or perhaps for new subscribers, see my post on the Bogus Energy Internet of Things where I describe, in relatable terms, that distributed dinky power supply compared to the grid makes very little to no sense. The PUF/Navigant article backs this with the prices of wind and solar renewable energy generation for distributed…
