The nature of labor in our world is constantly changing but one thing remains constant - without laborers, we would have no highways, trains, planes or automobiles, electronic devices, buildings, furniture, food, clothing, computer software, tv programming, health care, and the list goes on and on. Everything we have to improve our quality of life, comes from the labor of hard-working and intelligent people.
Vapor Compressor vs. Absorption
Most of us are at least somewhat familiar with the basic concept of vapor compressor refrigeration. This process is typically used in refrigerators and freezers, and room and building air conditioning units. A refrigerant gas is compressed and pumped through a condenser circuit where it condenses into a liquid and releases heat in the process. The condenser generally consists of a set of coils that allow for efficient heat transfer aided by a fan that helps carry the heat away into the surrounding air. In larger commercial systems, the heat might be carried away through a water cooling system.
There is a form of “robustness” inherent in AC power generated by rotating electro-magnetic fields (spinning generators). Those magnetic fields are a form of very short-term power storage that can fluctuate in reaction to changing loads. This is one form of reactive power or VAR (Volts-Amps-Reactive). VAR provides a level of stability to the power and adds a component of muscle to the power which enhances its transportability across distances.
Sometimes it feels like we are drowning in data. This can be discouraging but there has been great progress recently in tools to help with this data.
When it comes to energy data, your bills can be a great source, but how do you make that data useful? And what if the bills don't tell you everything you want to know? This article discusses the challenges and offers some great advice.
The importance of balance comes up in many contexts these days. Behavioral professionals speak of work-life balance. Mechanical engineers employ counter balancing shafts in motorcycle engines to reduce vibration. Airlines carefully fill seats to assure that the airplane's balance point is preserved.
I love our country. I love all of the good things our country stands for, and I'm grateful that our founding fathers had the courage to stand up to King George III and demand our independence. The risk of being hanged for treason made their actions even more remarkable. I'm also grateful for their wisdom as they set up a form of government that was as revolutionary as the war they were fighting. It has served us pretty well over the years.
We often hear references to "retro-commissioning," and if you're like many people, you've probably wondered what it means and how it might benefit your organization.
Energy consumption baselines are an essential part of any measurement and verification effort. Without a baseline, you really don't know where you started, and if you don't know where you started, you can't know how much progress you've made.
Evaluation, Measurement & Verification or simply Measurement & Verification ("M&V") is an increasingly important part of the energy manager's job responsibilities.
Millions of dollars are being spent on energy conservation measures ("ECMs"). These might include localized generation utilizing solar, wind or cogeneration
