23.5 Degrees

“On every world, wherever people are, in the deepest part of the winter, at the exact mid-point, everybody stops and turns and hugs. As if to say, ‘Well done. Well done, everyone! We’re halfway out of the dark.’ Back on Earth we call this Christmas.” – Doctor Who


As many of you know, I’m a big fan of solar power and energy storage systems that extend the sun’s amazing power throughout the night. We installed our solar array and batteries in 2021 and I can’t help but watch and measure the incredible energy we see from our friendly thermonuclear fusion reactor in the sky.

23.5 degrees. That’s the tilt of the earth that pushes our daily spin more directly to the sun, or away from it. Ironically, due to the earths elliptical orbit, we are actually closer to the sun in the winter than the summer, 92 million miles instead of 95. But the tilt makes a huge difference. It causes the sun’s rays to hit us in the northern hemisphere at an oblique angle, bouncing off of our terrestrial globe instead of being absorbed. It’s hard for us to sense it, but the solar panels feel it! We saw a peak of 51 kWh of energy per day during this summer, now we barely get 13 kWh. That’s a quarter of what it was during peak production! The sun didn’t get lazy, we just stop getting its rays.

We have all been observing the growing blanket of darkness that pulls over us, stretching deeper into our mornings and evenings. Days get shorter and nights grow longer. As we tick inescapably towards our winter solstice on December 21, we feel the cold wind, the fading colors and the melancholy shadows that scrape against our souls. Darkness is here.

Light a candle. This isn’t our first trip around the sun. Our human family has witnessed this solar dance since our beginning. We measure the sky and plot the stars to know where we are. We embrace the rhythm of the year by decorating it with celebrations and traditions. In the darkness of the winter, we light our lights. We illuminate our winter journey. We adorn our homes with fragrant greens, twinkling lights, cheerful ornaments and glowing fires. All the while, we know, the light is coming again. The glory of the sun will return! But for now, we celebrate.

It’s almost here. The dead of winter has arrived. Cuddle up with a warm cup of coffee or tea, your loved ones and a glowing fire. The light will return. We are halfway out of the dark! Celebrate it. 

Merry Christmas!
