All-Electric Homes Are Practical Now, and Can Help Mitigate Climate Change

The typical American home is powered electrically but heated by natural gas, propane or other fossil fuels. You and I can generate our own electricity with solar panels, but there’s no way for us to generate natural gas or other fossil fuel energy, so the transition to a “net zero energy” lifestyle necessitates turning away from fossil fuels and going all-electric.

Fortunately, technology has advanced — just in the last decade — to the point where going all-electric is totally practical, affordable, and a way you and I can mitigate climate change

At Golden Real Estate, our office was heated with natural gas until November 2017, when we installed a heat pump “mini-split” system and had our natural gas meter removed. With 20 kilowatts of solar photovoltaic panels, we were able to eliminate our natural gas bill but not increase our electric bill. We continue to pay just $11 per month to be connected to the electric grid (which functions as our “battery” thanks to net metering), but we are generating all the electricity needed to power, heat and cool our office building. We even have enough electricity from the solar panels to power our four electric cars without buying any net electricity from Xcel Energy. We hope other businesses will follow our lead.

Making the switch to all-electric at home is still in our future, because — like you, I suspect — we prefer gas cooking, gas grilling, and having a gas fireplace.

If, however, we can get beyond those preferences, it is possible now to heat our home and domestic hot water using heat pump appliances, and to cook our food with electric or induction cooktops and ovens.  Electric grilling is also available, although not as attractive from a taste standpoint to most of us.

All-electric homes was the subject of a talk by architect Peter Ewers at last week’s meeting of the Colorado Renewable Energy Society’s Jeffco chapter.  You can view an archived video of Peter’s talk at www.cres-energy.org/video.

Once we have removed gas service from our homes (and gas cars from our garages), we will have also eliminated the risks of explosion and carbon monoxide poisoning, too.  Wouldn’t that be great?

Some Favorite Home Improvements When Purchasing a New-to-Me Home

Who doesn’t want to make some improvements on a home they have just purchased?  Here are some of my personal favorites.

Energy efficiency is very important to Rita and me, so the first thing we do is pay for an energy audit by someone like Andrew Sams of Alpine Building Performance to identify opportunities for making the home more air-tight. This would likely include blowing more insulation into walls or ceilings and caulking around windows. It might also include installing an energy recovery ventilator (ERV) to bring fresh air into the home. This device warms cold outside air in the winter and cools hot outside air in the summer by means of a heat exchanger.

I love bringing sunlight into a home, not with traditional skylights but with sun tunnels. Most people are familiar with the Solatube brand, but I prefer the Velux brand. I had Mark Lundquist of Design Skylights install a 22-inch Velux sun tunnel in my windowless garage and a 14-inch sun tunnel in my windowless laundry room — and four large Velux sun tunnels in the Golden Real Estate office. Ah, sunlight!

Speaking of sunlight, we replaced every light bulb is our house with LEDs which are “daylight” color (like sunlight), not cool white or warm white. CFLs and incandescent bulbs are so 2010!

Installing solar photovoltaic panels is a no-brainer for us, especially now that the cost has dropped so much. Your roof doesn’t have to face due south. Southeast and southwest are good enough. (That’s our situation.) Since you might be driving an electric car someday, install as much PV as Xcel Energy allows to cover that future load.  If you have just purchased an EV, Xcel will allow you to install more panels based on anticipated future use.

Don’t you hate climbing a curb to enter your driveway? Developers install those mountable curbs the entire length of the streets in new subdivisions, not knowing exactly where each driveway will be. One of the first things I would do (and have done) is to hire a concrete company to replace the mountable curb with a smooth entrance. It cost over $2,000 for our 3-car-wide driveway, but I love it every time I enter from the street! Caution: the sidewalk will now be sloped slightly and pedestrians could more easily slip on ice, so be prepared to salt your sidewalk to eliminate icing!

When your gas forced air furnace needs replacing, consider replacing it with a heat-pump furnace or mini-splits. And when your gas water heater needs replacing, I suggest buying a heat-pump water heater. The cost is about the same, and, by converting to electricity for both, you will have eliminated the most common sources of carbon monoxide poisoning in your home.

Other improvements I’d consider include: Replacing carpeting with  tile in bathrooms; and replacing regular glass with Low-E glass on south-facing windows to reduce the harmful effects of sunlight on furniture, hardwood floors and artwork.

Feb. 21st Sustainability Session Focuses on Home Heating Methods

The second  session of Golden Real Estate’s sustainability series is next Thursday, Feb. 21st, 5-6 pm, in our South Golden Road office. Some seats are still available. Reserve yours by emailing  Jim@GoldenRealEstate.com.

At this session you’ll learn about the alternative energy-saving systems for heating and cooling homes and offices including our favorite method, heat pump mini-splits.

Our lead presenter will be Bill Lucas-Brown of GB3 Energy, who installed our mini-split system.

Golden Real Estate Launches Sustainability Series

As you may already know, Golden Real Estate is a leader in sustainability, as expressed in the value statement printed on all our yard signs: “Promoting and Modeling Environmental Responsibility.” And most of our agents, including myself, are Certified EcoBrokers, having taken extra training in all aspects of sustainability as it applies to real estate.

We’d like to share what we’ve learned with you, so we’re launching a Sustainability Series that will take place on the third Thursday of every month in our office.  We can accommodate 20 or more attendees in our office, but we will move it elsewhere if the demand exceeds our capacity, so please RSVP. You can do so now for all sessions.

Each meeting will focus on a single aspect of sustainability. Here’s the schedule for the first six meetings (subject to change):

Jan. 17th — Home Insulation — Walls, windows, foundations, crawl spaces, attics. (This is a bigger topic than you might think, but it’s also the cheapest and most effective path to reducing energy consumption.)

Feb. 21st — Home Heating Methods — Forced air, heat pumps, radiant floor, solar thermal, and other technologies.

Mar. 21st — Solar Power — Rooftop and ground-mounted photovoltaic, solar gardens, solar panels vs. solar roof tiles, and home battery storage/backup.

Apr. 18th — Electric Vehicles — What’s here now and what’s coming soon in cars, trucks, motorcycles and more.

May 16th — Sustainable Renovation — What are the more sustainable and popular materials and designs?

June 20th — Water Conservation — The latest concepts and products for conserving water use, both indoors and outdoors.

All sessions are 1 hour long and begin at 5 p.m. in our Golden office or nearby if a larger space is needed based on the number of reservations received. The sessions will be led by experts in the field, although you can count on me to add my own comments!

Go ahead and reserve your seat for any or all sustainability sessions now by sending an email to  Jim@GoldenRealEstate.com. We look forward to producing this informative series!

Golden Real Estate’s Sustainable Practices

1)   Our office produces more energy than it consumes. With our 20 kW of solar panels, we heat, cool and power our office and charge our six electric cars. We also provide free EV charging to the general public, yet our Xcel Energy bill is only $11.26/month.  At our request, Xcel removed our natural gas meter.

2)   We accept polystyrene from the public in our “Styrofoam Corral,” keeping over 200 cubic yards of the material out of the landfill every year.

3)   We use only LED light fixtures and have four “sun tunnels” (skylights) for naturally lighting our office.
