Did you know that less than a quarter of all workers employed in energy-efficiency fields are women? Solar companies, utilities, and other facets of the energy industry also report uninspiringly low numbers of female participation.

Today we are celebrating boundary-pushing women who are bucking the trend. Below are five energy warriors who are creating change that matters and generating new possibilities. These female architects, energy-efficiency specialists, and contractors remind us to get up and do something!

Use Cold Air to Heat Your Home? Use a Heat Pump.

Can you use cold air to heat your home? All you have to do is use a heat pump. 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.

The Home of the Future is Electric

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 |2021-07-19T11:22:10-06:00November 1st, 2018|Blog Feed|

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.

How The RFV Keeps the Lights On

By |2021-07-19T11:20:05-06:00September 12th, 2018|Blog Feed|

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 […]

The Annabelle Inn knows that saving energy means saving money and that’s why they use variable frequency drives.

Business owners looking to improve their energy efficiency often ask one question: which project saves the most money?

Basalt Cracks the Code

By |2021-07-19T11:16:29-06:00July 13th, 2018|Blog Feed|

We can’t overemphasize the importance of Basalt’s 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 […]

Technology is changing faster than ever. This is even true with lighting. Upgrading to LED is a no-brainer. But what to do with your old bubs? Bulb Recycling depends on the type:

Incandescent bulbs:

Odds are your house still has a handful of these. For years and years, they were the most common light bulb. You may be able to distinguish them by the metal filament. If you give them a light shake, you’ll […]
