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.
About a year ago, we finally weatherized our attic. Many people know that weatherization includes air sealing and insulation; many people do not know that those things have to be done in a very specific way in order to work… and the previous owner of our house was not one of those people. Doing the job wrong is ineffective at best and dangerous at worst.
We recently got a set of concrete steps put in at our house. As part of my atonement, this post summarizes what concrete is, why it’s so bad for the environment, why our governments can’t get enough of it, and what can be done to reduce the climate, health, and environmental justice impacts associated with the second-most-used substance on the planet.
The term “recycling” is a dangerous thing because of how it inaccurately shapes our perceptions around the plastic lifecycle. Most plastic put in the recycle bin doesn’t get recycled, but even the industrial process of “chemical recycling” doesn’t necessarily create a closed-loop plastic system. Instead, it can often fuel increased health risks for those living nearby, increasing global temperatures, and demand for additional plastic.
There are plenty of debates right now about energy independence and what that means, especially in light of Putin’s invasion of Ukraine and the resulting boycotts of Russian fossil fuels. There’s not much I can do as an individual, but these events prompted my switch to a third-party electricity supplier, particularly one that focuses on utility-scale wind and solar projects here in Pennsylvania.
The second and third posts on this blog were about third-party electricity suppliers in Pennsylvania and my impending switch to support one of them. Three years later, spurred by Russia’s invasion of Ukraine, I finally got around to making a choice and making it happen. This two-part series is my renewed argument for an easy shift away from fossil fuel-based electricity generation.
I’m off to a terrible start with Plastic Free July, since we’ve been out to eat three days in a row. Because of COVID, there is still a lot of single-use plastic in circulation. Our collective need for single-use plastic creates a lot of waste, but it also creates a lot of demand for the component materials, one of which is natural gas.
The thought of me providing life advice to other people strikes me as hilarious and pointless since I have always felt so aimless myself. I will admit, though, that the circuitous path that has led me to where I am has given me some perspective and helped me find things I love, and I was honored to share that at my alma mater this spring.
This spring I was asked to give a keynote speech at my alma mater and tell a group of physics students about the last fifteen years of my life since graduation. I was flattered, of course, but also baffled because when I was in school, my grades were not the best and I had no idea what I wanted to do with my life.
