The Cheapest energy
The cheapest energy is the energy you never use.
We spend a lot of money making greenhouses more energy-efficient. Better LEDs, smarter climate controls, and sophisticated energy management systems. Yet, here we have dozens of lights illuminating empty growing tables. Every hour those lights run without a crop beneath them is an expense with no chance of return.
Energy efficiency isn't just about reducing the electricity required to grow a crop. It's about eliminating the electricity we consume when we're growing nothing at all.
Before investing another dollar in technology, ask a simpler question: Are we making the most of what we already have?
