Legal-Weed Buzz Fades For Utilities

Bloomberg News, Mar. 30, 2017, by Chris Martin.
https://www.bloomberg.com/news/articles/2017-03-30/a-buzzkill-for-utilities-high-on-hope-for-legal-weed-power-surge

"With local restrictions on marijuana easing across the U.S., power suppliers from California to Maine were expecting a little buzz of their own from newly legitimate pot farmers. After all, a 5,000-square-foot warehouse filled with hydroponic growing systems can draw five times the electricity of a typical industrial user. But after an initial jolt in electricity use, when western states began legalizing marijuana cultivation and sales, demand has fallen off in some areas, according to utilities and analysts."

Designing a Dedicated Modern Wine Cooling System

Chiller & Cooling Best Practices, Mar. 2017, by Kevin Trowhill.
http://www.coolingbestpractices.com/industries/beverage/designing-dedicated-modern-wine-cooling-systems

"The temperature of wine must be kept stable throughout its production and storage in order to ensure final product quality that is acceptable for distribution and sale, and so cooling systems are an integral component of wine production. In wineries, the entire harvest can be destroyed by a temperature fluctuation during processing or storage, leading to catastrophic consequences for wineries. Cooling systems must meet three main criteria in order to be effective in wine production and storage applications: the cooling systems must be able to achieve the ideal temperatures for wine production processes; they must deliver consistent, reliable operation; and they must be well-designed for safe, convenient use."

Digester Mixing Fundamentals

BioCycle, Feb. 2017, by Craig Coker and Gene Smith.
https://www.biocycle.net/2017/02/14/digester-mixing-fundamentals-2/

"Anaerobic digestion (AD) is a biological manufacturing process where waste materials such as food wastes, animal manures and sewage sludges are converted, in the absence of oxygen, to products such as biogas and digestate. AD is traditionally a liquid process; that is, it often occurs in sealed reactors processing a thin liquid with a 93 to 99 percent moisture content.... Mixing maintains integrity of the decomposition process by improving circulation and consistency, and minimizing volumes of the scum and grit layers."

LEDs in Yerba Buena’s Vegetative Room Deliver a 9-Month Payback

Energy Trust Blog, Jan. 4, 2017.
https://blog.energytrust.org/leds-yerba-buenas-vegetative-room-deliver-9-month-payback/

"Yerba Buena, a CleanGreen™ Certified cannabis grower in Hillsboro [Oregon], prides itself on being a good steward of the Earth. Part of the company’s commitment to energy conservation involves looking for ways to reduce energy use. In an industry known for energy intensity, Yerba Buena became one of the first recreational cannabis growers to take advantage of Energy Trust’s technical assistance and cash incentives when the company replaced T5 fluorescent lighting in its vegetative room with tubular LEDs."

Flashbacks: Rural Electrification By the Numbers

Rural Electric Magazine, Dec. 2016, by Frank K. Gallant.

"....In 1940, just four and a half years after Roosevelt signed Executive Order No. 7037, 25 percent of American farms had been electrified. Among the bigger farm states, Indiana (37 percent), Ohio (42 percent), and Washington (57 percent) were electrifying fastest. Ten years later, 90 percent had been electrified nationally. REA was proving to be one of the most successful government infrastructure-building programs in U.S. history."

Room to Grow [LED Grow Lights]

HybridTech News, Nov. 23, 2016, by Chris Gromek.
http://hybridtech.us/room-to-grow/

"...it’s a brand new day for the electrical systems that serve marijuana grows and other indoor agricultural installations. And the lighting industry is taking notice. In March 2016, market research firm MarketsandMarkets released an analysis that forecasts a doubling in demand for grow lights worldwide between 2016 and 2022, with sales approaching $4.2 billion by the end of that period. More than half of that growth is expected to take place in North America."
