I was impressed when I learned about Hawaii’s goal of 100% renewable energy by 2045, but I was shocked to learn about some unintended impacts of wind energy development on Oahu’s north shore. Hearing from impacted residents was a great reminder that wind energy, like any tool, is not inherently good or bad – it comes down to how it is developed and used.
I was skeptical of the term “beneficial electrification” when I first heard it, mostly because I knew that more than half of our electricity in Pennsylvania was generated using fossil fuels. But when electric appliances are used in concert with energy efficiency measures, cleaner energy sources, and smart grid technology, beneficial electrification represents a meaningful step in addressing the climate crisis.
When I first saw an Earthship on the Discovery Channel in the ‘90s, I immediately wanted to live in one. While I now recognize that there are some cons in addition to the pros, I am still inspired by the radical and thoughtful design toward net zero energy use and waste. And I was delighted to stay in one recently and learn more about it first-hand.
We will soon have to replace our hot water heater, and I want to invest in something that will save energy and reduce our demand for fossil fuels, while also recognizing an inevitable shift toward home electrification. Initial and ongoing costs were a consideration in the debate between gas and electric models, meaning that this decision called for a comparative analysis. Spreadsheets were used.
It was a frustrating and disappointing week at work, with some losses for public health and climate action. I told my team that “if it were easy, someone would have figured it out already.” That said, I am grateful for the opportunity to figure it out with 15 other leaders from around the world this coming year as part of the Indo-Pacific Leadership Lab.
In honor of Climate Week and our need for stronger, swifter climate action, this post examines the new Allegheny County ordinance calling for the creation of a Climate Action Plan, which will reference Pennsylvania’s and Pittsburgh’s existing plans. Therefore, it’s important we understand the assumptions and omissions present in these example Climate Action Plans and how their approaches will shape the county’s next steps.
After years of intermittent research and data collection, I’m ready to share what we already knew: we’re saving money by using less energy! But how much, and how long until we recoup the costs of the weatherization work we had done in our attic in May 2021? We’ll never know for sure, but this exercise was a fun exploration of that complex question.
I finally got my hands on our gas usage data, thanks to a very patient husband and a helpful customer service representative. With this information, I’ve been able to take a look at how much we’re saving since our attic weatherization work in May 2021. I’m looking for ways to at least reduce our use of this fossil fuel until we’re in the position to eliminate it.
The world is talking more about decarbonizing our energy and transportation sectors, and one hot talking point is hydrogen. Hydrogen fuel cells can store energy like a clean battery, and hydrogen burns cleaner than fossil alternatives. However, the various processes of isolating hydrogen from input materials mean a range of environmental impacts, especially since the bulk of hydrogen is still produced using fossil fuels.
Once you’ve paid for weatherization work at your house, you may be curious how effective it is in saving you energy (and money). By employing data points called “degree days,” we can get a reasonably accurate view into how much energy gets used before and after weatherization work while keeping an eye on how much heating and cooling demand existed during the period in question.
