This afternoon a wild westerly wind is blowing and the sun bounces off a harbor churning with white-capped waves. It’s a wide awake day, cold and lively, after a night of high wind and ice and rain. The wind holds the house in an enthusiastic embrace, pleading with it to get up and dance an unruly lumbering winter stomp to the tune of its loud brass band, a Mardi Gras of percussive bass with overtones of wail and screech, in defiant, wake-the-neighborhood surround-sound. Let’s dance! The wind is yelling over the noise of itself.
Today we have a lot of sun and a lot of wind. It’s the perfect combination that gives our fancy batteries a big charge and gives us more electricity than we can use, unless we plan to spend the afternoon in a hot shower, hopping out now and then to use the vacuum cleaner and the power saw.
Our house had done without electricity for a hundred and fifty years before we installed the solar tracker and the wind turbine. It had seemed lovely to do without, but impractical. Now, hidden inside its walls, are the wires that allow us to light the rooms, use the internet, listen to music, and keep our food cold, not to mention fire up all those power tools.
But we can’t store this power. Our batteries, once filled, decline slowly but inevitably. They need constant recharging, from tonight’s wind and tomorrow’s sun, or any combination thereof. Even though we have more than we need, we can’t save it up for a rainy windless day, and since we’re not on a power grid we can’t sell it to anybody. Today our energy is abundant, and tomorrow it may be nothing but a trickle.
The ancient Israelites got into trouble out there in the wilderness when they tried to store the manna that came down from the sky as unmanageably as does our electricity. They thought they were wise to collect more than they needed, engaging in the sort of industrious and resourceful behavior the world admires. But the next morning the manna was moldy and rancid and they had to throw it all out. They learned, eventually, gratitude for a daily sustenance, a gift of life they could not control.
