Technology Connections with one of the best videos I've ever seen making the case for renewable energy.

The really striking bit pointed out that if the land in the US currently being used for biofuels for cars was converted to solar panels and batteries and even if we neglected even more efficient land use like agrivoltaics, the USA could more than power itself (including EV cars) without impacting food production.

My 9-year solar report card is in!

in the spring of 2017, I installed my solar energy system. The price tag was $42,000 (I got slightly used panels and saved a lot). It was a significant upfront investment...and worth every penny.

Now that we are in 2026, I ran the numbers. I passed the break even point in 2022, and am roughly $21,000 in profit! The total value generated so far is over $63k.

The next five years look even better. With utility rates rising astronomically, the system will generate another $36k or so. By 2030, the total profit should exceed $100k !!

If you are still on the fence about whether the math works on a solar investment….well, it did, does and will accelerate as energy prices keep inflating. It's much safer than many other investments in the current economy - at least until this regime is gone.

This high-angle aerial photograph captures a quiet suburban residential property blanketed in a thick layer of snow. A two-story beige house sits centrally near the top, featuring a large wooden deck on the back and a roof lined with solar panels that are visible as dark grids despite being partially dusted with white. To the left of the house, two large, rectangular ground-mounted solar arrays are tilted toward the sky but are completely obscured by snow, appearing as solid white angled planes. An oval above ground swimming pool sits frozen and covered in the center of the yard, while to the right, a large RV is parked next to a car. The surrounding trees are bare and frosted, and a road winds through the background, connecting to other snow-covered lawns and homes in the distance.

The old and the new. Solar and wind.

A landscape photo of a solar panel and a windmill silhouetted against a bright sky of horizontally streaked clouds. The solar panel is low in the foreground just right of center. The tall windmill sits on the right. The tail vane of the windmill is pointed toward the right and the large fan toward the left. The sky is streaked in many layers of dark and light clouds. A sliver of a lake is seen cutting from left to right just above the nearly black foreground. The windmill blades and tail vane has many holes in it from irresponsible shooters.

Major breakthrough from Korea: Scientists have transformed completely transparent glass into functional solar panels! ☀️🔬
This technology could revolutionize urban energy—turning every window in office buildings, homes, and skyscrapers into electricity generators without blocking views. Building-integrated photovoltaics (BIPV) taken to the next level. Transparent solar glass represents a massive leap for renewable.
