Combat Higher Fuel Prices with Efficient Heating Systems

Heating fuel prices have been volatile over the past few years. How high they may go in the future will depend on many factors including the world fuel supply situation, demand, level of inflation and the weather. Good energy conservation measures can help to offset this increase and keep production costs under control.

Keeping the greenhouse heating system in peak operating condition is a good starting point. It can save by increasing efficiency, providing more uniform temperature in the growing …

High Tunnels – Low Cost Seasonal Growing Space

At a cost of $1 to $2 per square foot, a high tunnel can add low-cost growing space for season extension or plant protection. High tunnels also do not rely on as much energy inputs as traditional greenhouses with furnaces and forced-air ventilation. Growers and researchers are finding many innovative ways to utilize these structures to supplement their greenhouse operations.

By definition, the high tunnel is a walk-in, hoop or gothic-shaped pipe frame structure that is covered with a single …

Shell Corn as a Fuel for Greenhouse Heat

Introduction

Corn has joined the list of popular alternatives to fossil fuels. Its high heat value, ease of handling, and ready availability in some sections of the United States have growers looking for information on cost, handling, and equipment suppliers. Although burning corn isn’t for everyone, a grower that is close to a good supply may find that it can reduce heating costs significantly.

Penn State Cooperative Extension has a Corn Energy Equivalent Table and an Energy Selector tool that …

Greenhouse Energy Conservation Checklist

High energy costs make conservation and efficient use of facilities an important part of today’s greenhouse operation. New greenhouse designs, better glazing, improved heating and ventilating equipment and new management systems should be included when upgrading or adding on. With typical annual energy usage being 75% for heating, 15% for electricity and 10% for vehicles, efforts and resources should be put where the greatest savings can be realized. The following checklist can help you make energy-saving improvements to a greenhouse …
