It takes a lot of energy to make a photovoltaic cell. Once it’s made, it gives you almost-free energy for a long time. Photovoltaic electricity is about investing a lot of energy now for a long-term payoff later.
Recently, for reasons I’d probably understand if I were paying attention, energy costs have dropped dramatically. To my way of thinking, then, it’s time RIGHT NOW to make a crap-ton of photovoltaic cells. Like, this month.
