Tag: geothermal heat

eothermal heating is the direct use of geothermal energy for heating applications. Humans have taken advantage of geothermal heat this way since the Paleolithic era. Approximately seventy countries made direct use of a total of 270 PJ of geothermal heating in 2004. As of 2007, 28 GW of geothermal heating capacity is installed around the world, satisfying 0.07% of global primary energy consumption.

If owners of commercial office buildings can incorporate variable-frequency drives (VFDs) into their HVAC systems, more often than not they probably should, says Pete Miceli, vice president, regional engineering manager for real estate service, development, and investment management at Transwestern’s Midwest office. Recently, Transwestern installed VFDs for supply and return

Renewable Energy for Onsite Power Generation

Renewable Energy for Onsite Power Generation

Although every situation is unique, and it’s difficult to generalize, Barry Worthington, executive director of the US Energy Association (USEA) in Washington, DC, says progress in renewable energy over the last 10 years has been phenomenal as systems become more efficient. Nevertheless, use of renewable energy for onsite power generation
