Fourth-generation plumber John A. Mullen delves into the growing trend of removing fluoride from municipal drinking water and its broader implications.

During extreme seasons, the importance of reliable heating and cooling systems becomes evident. This column focuses on heat pumps, highlighting key factors to consider such as size, efficiency, cost and environmental impact.

Columnist John Mullen explores the transformative impact of augmented and virtual reality on skilled trades education.

My heat pump water heater tour across America took me to a number of stops to those at the vanguard of carbon-cutting ways to heat water.

The Inflation Reduction Act offers significant incentives for geothermal HVAC projects through 2032, including tax credits and direct funding.

Hydrogen fuel can significantly reduce carbon emissions, improving air quality and health; hybrid systems combining hydrogen with other energy sources could enhance grid stability and flexibility.

he Inflation Reduction Act is expected to invest around $370 billion to improve energy security and reduce carbon pollution. The legislation is seen as a significant step toward combating climate change and promoting sustainable progress. 

Scientists have found polymetallic nodules deep in the ocean that could help us with energy storage. However, they are crucial to the ecosystem and deep-sea mining could have detrimental effects. Extracting thermal energy from the sun seems more practical, more reliable and less expensive.

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.
