We have been on a quest to reduce our carbon footprint and green our life since 2019 when we installed our first set of solar panels and bought a used Nissan LEAF. Wow, have we come a long way since then! We are excited to have exceeded our goals while saving more money than we had expected (and it looks like we may save even more in the future as energy prices increase). Driving EV’s is thrilling, especially knowing that you are driving free on Nevada sunshine and emitting zero carbon! We also feel more comfortable in our home with our new HVAC systems, while saving money and natural gas. Going green has improved our lives on all levels and we have already broken even on our investment. We estimate we will save $84,000-$100,000 over the next 20 years that we intend to keep our home and our cars.
Here’s a table showing our average annual savings and other interesting stats:

Reduction in Our Carbon Footprint
We are thrilled to have made our goal of an over 50% reduction in our carbon footprint! A similar US household emits 50 tons of carbon dioxide per year, so at 19 tons, we emit about 62% less. Changes made: Driving all electric vehicles, installing 30 solar panels, replacing old water heater and HVAC with heat pumps, using zone heating, switching to LED lighting, eating less meat and dairy and more fruits and veggies. We used the Nature Conservancy calculator (https://www.nature.org/en-us/get-involved/how-to-help/carbon-footprint-calculator/) if you want to see what your carbon footprint is.
Annual $ Savings
I realized that I was not capturing the full value of our solar panels in my previous calculations. Now that we are using all the electricity we produce, our utility savings is a mix of the value of the electricity produced at current electrical rates + the value of the gas savings at current gas rates. We now use 63% less natural gas than we did in the past.

Our savings are likely to increase over time as the demand for electricity and natural gas increases, particularly with the growth in data centers to power AI. I recently read an article that projected a quadrupling of our energy demands in northern Nevada! It is expected that residential customers will be shouldering a portion of these costs through increased prices. If this happens, we could see the value of our panels increase significantly.
We save an average of about $3,000 per year by driving our EV’s. We expect that savings to increase over time as the EV’s age. They will require less R&M than their comparable gas vehicles and we anticipate that gas prices will trend up over the 20 years we hope to drive these vehicles, increasing that savings as well.

Below is a breakdown of the total added home value and savings from the first table. I reference the savings I calculated when I did my last review in 2022. In that blog, I shared what we did in a lot more detail and offered suggestions if you want ideas for greening your own life (https://rhondaashurst.com/2023/03/05/year-4-its-all-coming-together/).

Between the annual savings of our systems, which all work in synergy with one another, we have saved $29,000 in 7 years! Our home value has increased by an estimated $34,000. For this calculation I took our estimated home value off Zillow and then multiplied by 5.5%. I based that on this article: https://www.energysage.com/news/solar-power-as-a-home-improvement-strategy/. I feel like the 5.5% is warranted given all the systems we have added to our home that increase its value by creating a stream of savings that will last for many years. That brings the total added value and savings to $63,000!

The Financial Bottom Line
After only 7 years, we are over $8,000 ahead on our green investments. If we keep our house for the 20 years+ that we are planning, I estimate we will save somewhere between $84,000-$100,000! If we continue to save 20 tons of carbon per year, in 20 more years we will save over 400 tons of carbon from entering Earth’s atmosphere. Regardless of how you feel about climate change, this is a smart thing to do from a financial perspective. If we see the increase in energy prices that are currently being predicted, we may end up saving even more.
The Importance of Solar Panels
Adding all of these systems increases electricity use. We now use about 2.75 times more than we used in the past. Prior to 2019, we were using about 6800 kWh per year in our household. Now our household uses about 13,500, almost double. We also put about 5,000 kWh in our EV’s in 2025, for a total increase of 11,700 kWh. What saves money and carbon is using the solar panels to generate most of this increase. Some of the increase is due to caring for my elders, which involves a lot of driving (e.g. we provide my mother’s transportation and run all her errands). We think that our own personal use is about what we produce at this point, which was our goal.
Our gratitude to Travis and the guys at Great Basin Solar (https://www.greatbasinsolar.com/) for the awesome job they did designing and installing our system.

Xeriscaping Our Yard
We also xeriscaped our yard from 2013-2023, which reduced our water usage by about 1/3. We live in a dry climate where water is precious, so we decided to change our lawns into a beautiful variety of shrubs, flowers, pavers with pots and DG. We love our new yard and it is a lot easier to take care of!
