Climate simulation software platform Sunairio has entered a pilot program with Xcel Energy-Colorado to simulate the electric grid of Public Service Company of Colorado, an operating company subsidiary of Xcel Energy, as it adds wind and solar generation capacity.

The program aims to improve the accuracy and increase the granularity of weather data used in grid planning.

Grid planning studies have traditionally quantified weather and energy variability risks by using historical weather data as an analogue for future weather events, says the company, which can fail to capture potential extreme events or account for the effects of climate change.

The pilot program hopes to overcome these problems by providing high-resolution weather data that both extends into the past and applies the latest intelligence from global climate models when looking to the future.

To achieve these goals, Xcel Energy will start by validating Sunairio’s historical weather and renewable energy generation datasets against both known measurements and proprietary generation data. Then, Sunairio will employ its climate simulation engine to simulate probabilistic outcomes of future hourly weather. These simulations are set to incorporate climate trends consistent with the most current generation of physics-based global climate models.

Finally, Sunairio will model future Xcel Energy’s customer demand, wind and solar generation by applying energy models to the weather simulations.

“We’re thrilled to apply our advanced modeling platform to Xcel Energy’s utility portfolio and show how this technology can support grid reliability in Colorado, with many renewable energy sites, diverse geographies and complicated weather patterns,” says Rob Cirincione, CEO of Sunairio.

Homeschooling

Published

Decent and intelligent people respect the rights of parents to homeschool their children, but there are two reasons for concern: a) socialization, failure to expose children to their peers, so that they may make friends and come to understand the norms of society, and b) the quality of the education itself.

Almost all homeschooling in the United States is conducted on the basis of a radical rightwing viewpoint, normally a blend of evangelical Christianity and Trumpism.

The Positive Effects We’ve Had on Others Are Profound, Whether We Know It or Not

There’s a theory that most people underestimate the positive effects they’ve had on other people.

Yes, that’s the theme of “It’s a Wonderful Life,” but it’s also the core of the 1995 film “Mr. Holland’s Opus,” in which a music teacher who deemed that his life had been a failure because he never completed writing a great symphony, is gently and beautifully corrected. Please see below.

Renewable Energy Concepts Can’t Violate the Laws of Physics

In the early days of 2GreenEnergy, my people and I were vigorously engaged in finding solid ideas in cleantech that needed funding in order to move forward.

I vividly remember a conversation with a guy in Maryland who was trying to explain the (ostensible) breakthrough that he and his team had made in hydrokinetics. When I was having trouble visualizing what we was talking about, he asked me to “think of it as a river in a box.”

“Oh!” I exclaimed. “You mean you take a box full of standing water, add energy to it get it moving, then extract that energy, leaving you with more energy that you added to it.”

“Exactly.”

I politely explained that the laws of physics, specifically the first and second laws of thermodynamics, make this impossible.

He wasn’t through, however, and insisted that, in his office, his people had constructed a “working model.”

Here’s where my tone descended into something less than 100% polite. I told him that he may think he has a working model, but he’s wrong; if he believes this, he’s ignorant; if he doesn’t, but is conducting this conversation anyway, he’s a fraud.

“But don’t you want to come see it?” he implored.

“No. Not only would not fly across the country to see whatever it is you claim to have built, I wouldn’t walk across the street to a “working model” of something that is theoretically impossible.”

I tell this story because the claim made at the upper left is essentially identical.  You’re pumping water up out of a stream, and then claiming to extract more energy when the water flows back into the stream.

Of course, social media today is rife with complete crap like this.  We’ve devolved to a point where defrauding money out of idiots is rapidly replacing baseball as our national pastime.
