Electricity or Thermal Energy?

TENs make it possible to significantly reduce electrical demand and level of electricity consumption year-round.
November 1, 2024
Jay Egg

Decarbonizing buildings and industry is crucial for reducing global energy consumption, predominantly in the form of heat. Thermal energy storage plays a significant role in this process by reducing reliance on electrical energy and batteries. Thermal energy networks that connect multiple buildings into a shared energy network can significantly reduce electrical demand and consumption.

Liquid-Cooled Data: Balancing Innovation and Sustainability

It is the simplest and most elegant solution to a carbon-neutral future.
November 1, 2024
John Mullen

Today’s data storage centers require considerable amounts of additional energy. Air-cooled systems have been the norm for data storage; however, liquid-cooled systems can handle greater internal heat displacement. This makes them ideal for energy-hungry AI tasks and preserving electricity.

PFAS Not Used in Pipe Production

Stringent regulations and standards govern plastic pipe production, especially those used for our drinking water supply.
September 2, 2024
Mimi Egg
Plastic pipe, typically made from materials such as PVC, PE and PP, does not contain PFAS, synthetic chemicals used in various industrial applications and consumer products. Stringent regulations and standards govern plastic pipe production, especially those used for our drinking water supply.

Water, Entropy and the Future of Energy Management

With unparalleled capacity to store and transfer energy, water can be a viable solution to a sustainable and resilient world
September 2, 2024
John Mullen
Thermal energy networks help buildings communicate with each other in warmth and coolness through piping networks. New columnist John Mullen explains how these shared energy networks use “waste” heat from sewage wastewater, collected stormwater or existing fire suppression systems to use elsewhere in buildings.

Americans Burn 50% Less Fossil Fuel in Their Homes Than They Did 50 Years Ago

While the ‘Electrify Everything’ trend may be relatively new, many homeowners have been steadily electrifying for decades.
August 5, 2024
Joseph Wachunas

While the ‘electrify everything’ trend may be relatively new, many homeowners have been steadily electrifying their energy sources for more than five decades.

Too Much, Not Enough

How did water go from abundant to scarce in Mexico City?
August 5, 2024
Max Rohr

\What is now hot and dry Mexico City used to be a lush agricultural area. Shifting water levels caused by flooding were controlled with floating agricultural infrastructure. The Spanish conquistadors decided to build there, but constant flooding resulted in draining the once enormous Lake Texcoco. Today, much of Mexico City rests in the lake basin; the city’s population explosion depletes groundwater.

Wastewater Energy Transfer Hits the Big Time

This technology, which extracts the heat by sending wastewater through a heat exchanger, is closely related in concept to ERVs.
July 7, 2024
Jay Egg and Kristy Egg

Wastewater energy transfer has risen to the top as a preferred initial method to begin the decarbonization efforts for commercial buildings and thermal energy networks of all types and sizes.

The Warehouse of the Future – and Past

Two Missouri caves are examples of working with the local geography to reduce the climate and security variables affecting business owners.
July 1, 2024
Max Rohr

When imagining a distribution warehouse, setting up shop in an old, underground mine doesn’t come to mind. And while PHCP tools, equipment or building materials don’t need to be housed in a cool climate, an underground space can help curb the theft of expensive materials such as copper pipe and fittings.
