Grow Year-Round on Clean Energy
Sustainable Growing, Made Practical for Small Farms

We help small-scale growers produce more with less, pairing energy-efficient greenhouses with clean power and smart growing systems that cut operating costs and reduce water, fuel, and pesticide use.
Clean Energy Greenhouses, SPC (CEG) faciltates transition: Many predominantly small-farm soil farmers are facing a paradigm shift that requires making a transition from conventional agriculture to something new and unfamiliar.
In this time of climate change, reduction of arable land, floods, wildfires, drought, and even going out of business because of these conditions or forced sale of family farms to Big Farma due to high operating costs,
CEG is offering a way to continue farming at lower cost: To reduce water use by up to 90%, reduce costly energy use, reduce greenhouse gas emissions, reduce agri-chemical use, increase extended-season yields, and potentially increase profitability by serving local markets with fresh organic produce (fish, vegetables, berries, and possibly fruits and nuts from dwarf trees sized for greenhouses).
Our offerings include passive-solar greenhouses, vertical hydroponics, aquaponics, agrivoltaics, and permaculture add-ons. Explore what we do, and then reach out and we'll help design a system that fits your farm.
Our Solutions
We start with a proven passive-solar greenhouse.
We source high-performance passive-solar greenhouses proven by small, medium, and large-scale growers across Asia and Europe. As the exclusive North American reseller, we bring that technology to small farms in the US and Canada at budget-friendly prices.
Oriented east–west, each greenhouse has solid, heavily insulated north, east, and west walls and a transparent south-facing polycarbonate roof and wall. Its thermal mass stores daytime solar heat, and a roll-down night blanket holds it in so you can grow warm-season crops through freezing winters with little or no auxiliary heat.
Then we add the growing and clean-energy systems that fit your farm.
We offer options for integrating aquaponic and vertical hydroponic systems that enable you to extend your growing area and season and cultivate maximum yields. These solutions can also help you save water while creating a nearly self-sustaining environment.
Clean-energy options can help you significantly reduce your dependency on fossil fuels. Agrivoltaic system add-ons can both generate clean energy for greenhouse operations and enable you to sell excess power to the utility company for additional year-round supplementary income (where net metering is available).

Water Savings
Recirculating systems cut water use by 70% to 90%, versus traditional field farming.
Our systems help small farms thrive, with lower startup and operating costs, a smaller environmental footprint, and the capacity to grow fresh flowers, organic vegetables, herbs, and fish or prawns for local and regional markets.
Benefits
Lower Energy Use
Thermal storage and clean-electric power reduce fossil fuel dependency by 20% to 100%, depending on your climate and growing season.
Year-Round Harvests
Controlled environments keep production steady, no matter the weather outside.
Pesticide-Free
Enclosed greenhouses create natural biosecurity, reducing or eliminating the need for chemical herbicides, insecticides, or fungicides.
Integrate Innovative Systems

Vertical Hydroponics
Vertical grow towers maximize production in a small footprint, extending your season and increasing yields while dramatically cutting water use.

Aquaponics
Combine fish or prawn farming with plant cultivation in a closed-loop system that minimizes artificial fertilizer, uses water efficiently, and aids winter heat retention and summer cooling.

Power your greenhouse with solar, wind, hydrogen micro-grid, or micro-hydro to cut natural-gas and grid-power costs. And, where net metering is available, earn extra income by selling surplus power back to the utility.
Agrivoltaics

Build raised hugulkultur beds inside your greenhouse to create self-fertilizing soil that holds moisture and generates gentle heat as it breaks down.
