Conserve
Energy, Save Money:
Opportunities for Nova Scotia farms
Julie Bailey hopes to keep Atlantic Canadian farms
competitive by identifying energy saving opportunities which will
reduce energy costs and lower greenhouse gas emissions (GHG) on
Nova Scotia farms.
A Farm Energy Specialist at NSAC in Truro and Professional
Engineer, Julie recently completed her Master of Science thesis
where she researched Nova Scotia farmers’ perceptions and
considerations in implementing energy conservation measures. With
this information, she plans to make recommendations for the delivery
of a future energy conservation program for farms and update current
energy baseline data. Currently, there is no province wide energy
conservation program targeted specifically at Nova Scotia farmers.
To understand perceptions on energy conservation opportunities,
Julie conducted a survey of all farm commodities in Nova Scotia
with the assistance of the Nova Scotia Federation of Agriculture.
With nearly 700 surveys mailed to 16 commodity groups, a good return
of 32 per cent of farms responded.
Findings from the research showed a demand for energy
conservation measures on farms. A particular challenge was dairy
and hog/poultry farms, who reported double and triple the average
annual energy bill of farms, respectively. For all farms, over half
of the energy bill came from petroleum product use such as diesel
fuel.
Julie says that the top energy concern was operating
costs. “While variable by farm type and size, the top energy
uses on farms surveyed were vehicle and mobile equipment and heat
and lights.”
A majority of farmers reported an interest in using
energy conservation strategies, with many of them already doing
so, including modifying their own behaviour, adding insulation and
improving lighting practices. Large farmers and those concerned
for the environment showed the most interest in these strategies,
even though very few farmers appeared to be using renewable energy
technologies.
Cost savings were of particular interest to farmers
and those interested in energy efficient options wanted a three
to five year payback on their investment. Longer paybacks were more
acceptable for renewable energy options.
Julie says that “Opportunities exist that match
NS farmers’ financial expectations, for example; heat recovery
equipment and vacuum pump variable speed drives for dairy farms,
efficient fans for hog and poultry and biogas for very large hog,
poultry and dairy operations.”
Julie’s research also involved on-farm energy
audits for several farm types in the province. The purpose was to
identify where energy is used and identify opportunities to reduce
energy consumption.
Her research and similar studies in Ontario showed
that dairy or hog farms could potentially save 15 per cent on electrical
expenses. This would be equivalent to $1560 annually or 12 tonnes
of carbon dioxide equivalents per farm for hog, poultry and dairy
operations in this province.
Julie says the results of her study shows an interest,
opportunity and need for energy conservation on Nova Scotia farms
and says consideration should be given to developing an energy conservation
program for farms in this province.
She also noted benefits from the EcoEnergy Retrofit
Program (EnerGuide) for farm houses. On average, this program has
seen reduced energy consumption of 28 per cent and a reduction of
GHG emissions by 4.1 tonnes annually per house that has undertaken
energy saving renovations.
“A program could include information tailored
for different farm commodities, outlining energy conservation options,
potential costs and savings and funding availability. It could also
include energy audits, education activities, technology demonstrations
and financial incentives for implementing energy conservation measures.”
Julie’s interest in energy conservation has
extended beyond her research at the NSAC. Using her expertise, she
recently conducted an energy upgrade in her own 104 year old house
in Earltown so it can be more energy efficient, complete with a
solar hot water heating installation. She has also given several
presentations on energy efficient home renovation to different community
groups in the Truro area.
"I encourage all homeowners to consider participating
in the EcoEnergy Retrofit Program. There are significant savings
opportunities for home energy bills and the rebates can cover part
or all of the cost of the upgrades. There are significant savings
opportunities on-farm as well and there is a need for a program
to promote and educate farmers on these opportunities.”
(Julie’s research was funded by a
prestigious Canada Graduate Scholarship supported through the Natural
Sciences and Engineering Research Council of Canada (NSERC). She
was supervised by Dr. Robert Gordon, a Canada Research Chair at
NSAC in Agricultural Resource Management.)
