Three jokers in the energy deck

This is the era of Big Oil. Could the next be the era of Big Efficiency?

 

A new report by the American Council for an Energy-Efficient Economy suggests the possibility. Re-invented with today’s smart energy technologies, energy efficiency could displace 40 to 60 percent of our total energy needs by the year 2050, according to The Long-Term Energy Efficiency Potential:  What the Evidence Suggests.

 

Sound far-fetched?  ACEEE says history backs its…

Energy Planning, Energy Action

Vermont has a new comprehensive energy plan that is full of thoughtful - though non-binding and unfunded - ideas. The plan calls for meeting 90% of the state's energy needs through renewables by 2050.

Energy professionals know that it makes sense to dramatically reduce the energy requirements of homes and meet a large portion of remaining needs with renewables. We know how to do the work, what we don’t know is how to pay for it – solar panels and insulation are just…

Just Signed up for OG&E Smarthours Program, A new way to manage energy use

How SmartHours Plus works: It costs more for electricity during peak periods of high customer demand.

Other factors, like weather conditions and the time of year, also drive electrical prices higher. SmartHours Plus,

sometimes known as Variable Peak Pricing (VPP), allows you to save when costs are lower, or off peak. Peak hours

are 2 to 7 p.m. weekdays, and prices during those hours vary based on demand (see chart). You’ll get advance

notice of tomorrow’s peak price the…

Are You in PA, NJ, or DE? Do You Plan to Become a BPI Testing Center?

 I'm wanting to assess which tri-state BPI Affiliates are becoming BPI Testing Centers.  And, in order to not over flood the area with too many Testing Centers, I'm looking to pool resources. We have 25 test computers. This will keep costs down.  If you are becoming a Test Center, or if you know an entity that is, please share that infomation.  It will be public soon enough.  I'm also wanting to assess the need for traveling Proctors.  If you need Proctors, please share that information…

Figuring out how to go green without going crazy

Utilities worry about a lot of things, such as keeping the lights on, earning a return for investors, and making regulators and customers happy with their service.

Now there is a new worry: How can they protect customers from what one utility refers to as “mental fatigue?”

In this particular case, the utility raises the issue as it prepares to invite homeowners and small businesses to select from among new and possibly complicated rate options made available because of smart…

Heat transfer: How Heat Gets Out of Your Home and Costs You Money.

by Don Ames,  www.detectenergy.com

Heat flows out of your home in two ways, transmission and air leakage. Transmission and air leakage occur through all surfaces of the home - walls, floor, roof, windows and doors.

The amount of heat transfer depends on two factors: thermal resistance and surface area. Thermal resistance has to do with the quality and quantity of the material in the walls, floor, roof, windows, and…

Please read the article and catch the screen cast at the end of the article.

US beats expectations saving energy

Americans tend to beat themselves up over their imperfections. We eat too much, watch too much TV and owe China too much money. Despite all of our sloth, we can feel good about one area: our progress saving energy.

report issued this week by the Institute for Electric Efficiency found that we saved enough electricity to power almost 10 million homes in 2010 (about 112 MWh). That’s 21…

Where to Look For Construction Flaws and Energy Waste

by Don Ames,  www.detectenergy.com

Construction flaws waste energy, reduce comfort, and encourage building deterioration. A little knowledge about construction methods can help you locate and correct these flaws. Let's face it, homes were not created equal, homes are the result of a hundred hands belonging to fifty different people that will never live in the house, but, never-the-less, have great influence…

Acronym CRAZY...

I don’t believe this is an industry specific issue but we do seem to have an excess of acronyms. 

For example we have RESNET, HERS, BPI, LEED, CSG, ACCI, ANSI, OSHA, WISHA, OMG, & LMAO! 

Confused yet?  No – then let’s try these on for size… ACH50, ACHNAT, SIPS, DMHP, HP, WH, HVAC, CFM, ELA, SLA and IECC, MEC, ASHRAE but don’t forget NYC!
