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.
In recent years, we have been highly aware of the impact we have on the world around us, and, just as importantly, the impact on our wallet. Part of understanding the impact we have on both of these things, is understanding in what ways we use energy. If we can identify what ways we use energy, we are closer to knowing the ways we waste energy.
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.
If you’re like most of us, when your power bill shows up each month, you look at the amount due, cringe a bit, and send it to accounting to be paid. It is what it is – right? But if that sounds like you, you could be missing opportunities to save money.
