Key issues for nursery owners:
•Do I have $50,000+ for a comprehensive energy efficiency solution?
•Do I trust suppliers energy and cost saving estimates?
•I don’t want to pay $4,450 for an energy audit just to find possible solutions..
With the constant increases in electricity costs over the last several years, and current projections that electricity costs in Queensland will continue to increase by a minimum of 3.5 percent per year, nursery managers must consider all areas of the business to reduce energy use and operating costs. This article is the first in a series looking at different methods to reduce irrigation energy use in production nurseries.
In this month’s Nursery Paper NGIA Environmental & Technical Policy Manager, Dr Anthony Kachenko provides an overview of carbon footprinting and explains how best to utilise Nursery Footprint in a production nursery environment.
Improving water use efficiency in a production nursery begins with having a clear understanding of the infrastructure and practices currently in place. Irrigation, Drainage and Energy Management Plans, or IDEMPs, describe the infrastructure and management practices in operation at a business, and outline opportunities, suggestions and designs for on-farm improvements, to ensure the business remains profitable and sustainable into the future.
A recent development in the way electricity companies provide power to businesses, is the requirement that a customer ensure that the power factor of any electrical installation measured at the consumer's terminals is not less than the power factor.
Taking a whole of system approach to improving the efficiency of pumping systems can reduce energy and maintenance costs, and more closely match system capacity to pumping requirements. The following is a systematic approach that can be used to identify issues and improve man existing pumping system.
Depending on use patterns, an electric motor can use four to 10 times its purchase price in electricity annually. Because of this it’s important to consider operating costs as well as capital costs when selecting electric motors. The following article suggests some strategies that can be used to improve the energy efficiency of electric motors on pumping installations, but the same principles can be applied to any infrastructure using electric motors.
The purpose of the Energy Savers program is to assist farmers in reducing energy costs by supporting the accelerated delivery of improvements in on-farm energy use.
The program will provide information on the benefits of adopting new and more efficient technologies and provide the necessary tools to manage and reduce electricity usage.
One of the most valuable attributes of a greenhouse is the opportunity to manage the internal environment to achieve optimal crop productivity. Energy is a critical component in this objective and is increasingly one of the key factors in greenhouse profitability. The aim of this project was to make it easier for greenhouse growers to reduce costs and carbon emissions and to make better energy (heating) investment decisions. This was achieved by giving growers easy to use and reliable tools for finding ways to save energy and by evaluating and demonstrating the cost to benefit of alternate energy systems.
