I created a space for people to make connections and learn from each other. I call it Grok.Town and plan to start up a Lemmy instance at that domain, but for now it’s a space on Matrix with a few rooms to chat and get to know one another. Check it out @ https://matrix.to/#/#groktown:matrix.org

  • Our research includes linear regression, principal component regression, and spatial error models to provide empirical evidence for the relationship between the adoption rates and socio-economic, geographical, and technical factors while identifying characteristics of adopter groups. The results suggest that the relative advantage factors – electricity prices and solar irradiation – play the most significant role across all regions and market segmentations. Statewide policy indicators are the second most significant factor, followed by socio-economic variables on employment status, remote working, car ownership, and property value. Our results indicate that homeowners do not only differ in their circumstances but also in their motivations.



  • The theoretical explanation:

    When RPVSPs are installed on roofs, they absorb a significant amount of solar energy, converting some of it into electricity but also generating heat in the process. This heat is released into the surrounding air, leading to an increase in air temperature around the panels. Moreover, the elevated installation of RPVSP creates two hot surfaces: the top surface of the panels and the underside surface. As air flows over these RPVSPs, it picks up heat more efficiently than it would from typical building or ground surfaces. Observational studies in the literature have shown that areas with RPVSP arrays can experience higher daytime air temperatures compared with reference sites without RPVSP.

    In essence, the heat that would be absorbed by the building (requiring more energy for cooling the interior) is instead absorbed by the panels and conducted to the surrounding air which creates a convective heat exchange cycle on a city wide scale. It would be interesting if this were compared to awnings (and pegodas) that have been in use for centuries for passive cooling of space in and around buildings.

    Further, It seems like this would call for the use of phase changing material to absorb the heat from the back of the solar panels which would reduce this intensification of the urban heat island effect as the heat energy would be use in the phase change process during the day and slowly released in the reverse phase change at night without conducting more heat into the building.

    None of this seems to have any real consequence on the global warming effects of greenhouse gasses (primarily natural gas [methane] and Carbon Dioxide). But it is a more accute concern that is more likely to be addressed through local ordinances, laws, and regulations.






  • Rather than take a defeatist veiw from this line if thinking, it will do well for your mental health to first spend more time, energy and thoughts on things you can control. Not just things related to environmentalism, but broadly reduce energy, engagement and focus from the things you don’t have significant control over and direct them to those things you do have control. It’s good to get a broad picture and observe the world around you outside of your control in small doses, but it’s easy to over indulge in an unfocused survey of problems in the world, especially on social media. (I include Lemmy communities in the social media category).

    Furthermore, when you do engage with these problems, do so with more narrow focus and in more depth with an eye towards understanding the level of impact the problem has and what organizations or policy positions you can support to amplify your limited influence over the issues that causee the problem. In this way you can mitigate the feelings of helplessness and sense of there being many existential and imminent problems you need to contend with but cannot remedy. You can turn seemingly untouchable solutions into real possibilities without overwhelming your emotional capacity by working with others.
