From Sky to Tap: Zero Mass Water Literally Pulls Drinking Water From Thin Air

From Sky to Tap: Zero Mass Water Literally Pulls Drinking Water From Thin Air

Last week on vacation with the family in Puerto Rico, I took a small detour from the touristy stuff to check out a cool new technology. Driving just over an hour west of San Juan, I headed south, and soon found myself passing through an intensely green forested and serrated landscape of karst limestone outcroppings. I followed the winding road about a half hour south to the town of Utuado, home of 33,000 souls and one of the communities most seriously affected by hurricane Maria. After asking directions three times (my destination was not on Google Maps), I eventually found my way to the Utuado Estacion de los Bomberos – the local fire station.

There I introduce myself to the officer in charge (he was perhaps a bit confused as to what TREIA’s storyteller in residence actually does) and asked permission to accompany him to the roof. We climbed a vertical ladder set into the wall, opened a hatch, and walked over to view a secondary lower rooftop.

Switching to Electric Vehicles Could Save the US Billions, But Timing Is

Today, less than two percent of the vehicles Americans buy are electric. But within the next three decades, some automotive industry experts expect electric vehicles could make up the majority of US and global car sales.

All told, American drivers log about 3 trillion miles per year, consuming more than 170 billion gallons of gasoline and diesel in the process. Converting all those road miles to electricity would place new demands on the nation’s system for producing and delivering electricity.

As part of a major energy infrastructure studywe are seeking to understand how an increase in electric vehicles (EVs) might change how energy is supplied and consumed. So far, we have figured out the impact of electric vehicles will depend on where you live and when they are charged.

New report shows tightening ERCOT reserve margins

A new Electric Reliability Council of Texas Capacity, Demand and Reserves (CDR) report shows that the planning reserve margin for summer 2019 is forecasted to be 8.1% based on resource updates provided to ERCOT from generation developers.

This is 2.9% lower than what was initially reported in the May CDR, ERCOT said. The report shows reserves are expected to increase to 10.7% in 2020 and 12.2% in 2021.

The ERCOT CDR Report includes planning reserve margins for the next five years.

Exxon’s Power Play Points to Texas’ Future

As stories about the energy transition go, Big Oil going big on solar power in the heart of America’s biggest oil patch is as transitiony as it gets. Besides the symbolism of Exxon Mobil Corp. signing up for 250 megawatts of solar power (plus the same amount of wind power) in the Permian basin, though, it is also part of a big change gathering momentum in the country’s biggest electricity market: Texas.

Despite lots of sunshine and power demand, the state hasn’t embraced solar power in a Texas-sized way. Last year, it ranked sixth in the U.S. in terms of solar generation, just behind Utah. But that appears to be changing. As of the end of November, the state’s solar pipeline was at almost 37 gigawatts, up from less than 25 GW at the beginning of the year, according to the latest monthly report from the Electric Reliability Council of Texas (ERCOT).

ERCOT sets record wind output of 17,920 MW amid wintry weather

ERCOT sets record wind output of 17,920 MW amid wintry weather

Houston — The Electric Reliability Council of Texas set a new wind output record of 17,920 MW on Monday afternoon as a cold front was moving into the area with windy conditions.

The new output wind record was set at 3:32 pm CST Monday and surpassed the previous record of 17,542 MW set in February, by more than 2%, according to ERCOT Wind Integration Report.

US Corporate Renewable Energy Procurement Hits Record Levels

US Corporate Renewable Energy Procurement Hits Record Levels

Corporate renewable energy procurement is currently on track to exceed 5 gigawatts (GW) in 2018, according to figures announced recently by the Renewable Energy Buyers Alliance, which is so far tracking a new record of at least 4.96 GW worth of new capacity already acquired this year.

So far this year (as of October 19) there have been 59 deals signed by US corporates for a total of 4.96 GW — already a new record over the previous high of 3.22 GW set in 2015, and representing the most first-time buyers in a single year.

Georgetown won $1 million to capture and store solar energy. Here’s what happens next


The city of Georgetown is going one step farther to become energy-independent.

After winning a $1 million grant from Bloomberg Philanthropies U.S. Mayors Challenge on Monday, city officials said they plan to lease rooftop space on homes to install solar panels as well as additional space to install storage batteries that will allow the city to collect and store solar-generated energy. Leases will require final approval from Georgetown City Council.
