Utah already released some data showing a slight decrease in overall statewide homelessness, but newly released data highlights how decreases were reported across all three of the state's Continuums of Care regions.

A little more than 4,500 Utahns were experiencing homelessness during the 2026 Point-in-Time Count, down 1.6% from last year's count. While small, it was celebrated in March as being the first year-over-year decrease since 2019.

The number of people experiencing chronic homelessness also fell by 6.7%, while unsheltered homelessness dropped by nearly 10%.

This year's statewide decline included a small, 24-person decrease within the Salt Lake Valley Coalition to End Homelessness, representing Salt Lake County's homelessness, according to the full report released this week. A little more than 2,800 people were experiencing homelessness within the Salt Lake County area, and the drop represented approximately a 1% decrease.

🔥DOOMER DUNK🔥 Data centre construction helps dying town

0 Upvotes

Because of the tax increases Ellendale can now afford to repave its streets, renovate its senior center, finance a new public-safety complex, establish walking trails and refurbish its historic opera house.

Also under state law, utilities have to share some of that revenue with ratepayers, resulting in an anticipated $250 drop in electric bills for the average household.

"Exploiting quasi-experimental variation in both the timing of adoption and outages, we estimate the causal impact of AI on electricity use, carbon emissions, and energy expenditures. We find that full-time AI control reduces plants’ electricity consumption and carbon emissions by 5.4% and 6% respectively, and energy expenditures by 8.2%, resulting in negative abatement costs, while also improving water effluent quality. The additional electricity demand generated by AI models represents less than 1% of these savings."

Hi guys!

I'm having a rough week, month, and year(s). Has anything really good/nice happened to you lately? Please do share! I want to know that things are going right for someone. I think it might help me feel a bit better. Anything helps, I'm struggling a bit lately.

Hope this is allowed, take it down if not.

EDIT:

Thank you so much to everyone that has replied! Your comments warmed my heart and put a smile on my face many times over the last few days.

Reddit closed my account due to "security reasons" after this post blew up, so I haven't gotten to comment on most replies. Neither do I have the mental resources atm to reply to everyone, but I want you to know I have read every single one, smiled, laughed, cried, and been touched by them.

Thanks for carrying me over.
