Our interactive exhibit at the March screening of “The Human Element.” PC: Dan Bayer.  “What we have to unflinchingly look in the eye is how much choice we still have.

Use Cold Air to Heat Your Home? You Bet.

Can you use cold air to heat your home? You bet. Just ask a Swede. In Sweden, a legit cold climate, they're staying toasty with heat pumps. Unlike other heating systems, heat pumps don’t generate heat to keep your home cozy and warm — they take heat from the air. Recent advances mean this technology is now burning a hot path into cold-climate homes in the US. Heat pumps warm a home by transferring heat from [...]

The Home of the Future is Electric

By |2019-01-16T12:07:00-06:00January 10th, 2019|Blog Feed|

We know that our fossil fuel addiction is destabilizing the climate. And yet, in much of our daily lives—from showering to sautéing—it’s been difficult to find a viable alternative, so we continue to emit greenhouse gas (GHG) emissions. That’s all changing: electricity is getting cleaner, creating a clear path to a fossil-free future. What if everything ran on gasoline? This Nissan Leaf commercial has electricity looking better and better. [...]

Don’t be a Turkey: How to Talk Climate This Thanksgiving

By |2018-11-09T10:53:24-06:00November 1st, 2018|Blog Feed, Uncategorized|

Over 27 million Americans (65% of the population) rarely -- if ever -- talk about climate change.*  This jaw-dropping number of people choose not to mention climate, when it is impossible for me not to talk about it. I talk about it over margs with friends and over cake at my cousin’s wedding; I also let my senators know what I think they should do about it. via GIPHY But I get it. [...]

Faces of Energy Efficiency

We hear about the role that oil and natural gas production play in Colorado’s economy all the time. But what if I told you energy efficiency -- not oil and gas -- is the No. 1 creator of energy jobs across the Southwest? A net of 67,000 jobs were added to the energy efficiency sector last year -- beating out new jobs in oil and natural gas production, electric power generation and other energy industries, according to a 2018 [...]

How The RFV Keeps the Lights On

We’ve got a long list of ways you can use less energy, but a 72-hour power outage doesn’t make the cut. A blackout of that scale was a real threat during the early days of the Lake Christine Fire. Crews from Holy Cross Energy and Xcel Energy, two of the electric utilities serving our region, were working hard to keep the power flowing. The fire may be contained, but the utilities are still working around-the-clock to recover from the damage [...]

This Little Box Can Help Your Business Save Big

The Annabelle Inn knows that saving energy means saving money. Business owners looking to improve their energy efficiency often ask one question: which project saves the most money? For Annabelle Inn, the answer was adding variable frequency drives (VFDs) to the hotel’s hot water circulation pumps, a simple move that’s projected to save the hotel almost $2,500 annually. Most commercial buildings have motor-driven fans and pumps that behave much the same as they have for years: the [...]

Basalt Cracks the Code

We can’t overemphasize the importance of building codes. This dense and complicated set of guidelines on mundane things like insulation and glazing requirements isn’t fun leisure reading. But they are one of the most important tools local governments have to reduce energy use in homes and businesses -- and to take action on climate. With the goal of creating homes that use less fossil fuels while improving the comfort and well-being of inhabitants, CORE contracted with two sustainable building specialists [...]
