Our increasing utility bills are a clear indicator that energy costs are rising. Expect the pain to continue into the future. As an important energy producing region, Albertans are benefiting more from rising energy prices than the consuming parts of Canada. This fact is small comfort to families and businesses whose finances are being strained under the impact of higher costs for natural gas.
What technologies can we exploit to cut natural gas consumption and thereby cut energy cost for our homes and businesses?
Home and business owners can reasonably achieve a 50% reduction in energy consumption by making various improvements. To achieve this reduction, owners will have to make investments that will take from 3 to 7 years to reach a break-even point. If energy prices continue at their current record levels, the break-even point will of course be achieved at the lower end of the range.
Compact Fluorescent Bulbs
The cheapest and easiest-to-install energy saver is low watt compact fluorescent bulbs. With a screw base that fits an existing incandescent light bulb socket, compact fluorescent bulbs operate on a quarter of the energy used by incandescent bulbs and last ten times longer. From his personal experience, Ken Hogg, a Calgary-based energy efficiency consultant, has shown that the higher-tech bulbs reach a break-even point after only two years. In high-usage areas, the break-even point can be 18 months.
Thermostat with a Timer
Another simple idea is a thermostat with a timer that keeps the temperature lower when premises are not occupied. Such a thermostat can reach a break-even point after only one year. Peter Mirosevic, President of CRW Ltd., a Calgary-based renovation contractor, regularly recommends higher-tech thermostats to his clients.
Solar Hot Water Heater
A more high-tech idea to reduce energy consumption is installing a solar hot water (SHW) heater coupled to a power-vent, natural gas water heater. The saving is over 50% of the natural gas typically consumed by non-SHW units. SHW heaters reach a break-even point after about 10 years. The break-even point is shorter for families with more teenagers who tend to shower longer and more frequently.
Solar Panels for Space Heating
The next high-tech idea is solar panels for space and water heating. For a state-of-the-art example of this technology in use on a community-wide basis, visit Sterling Homes at the Drake Landing subdivision in Okotoks. These homes use 90% less natural gas for space heating and 60% less for water heating than conventional homes. The first families are scheduled to move in in early 2006.
Keith Paget, the Manager of Special Projects at Sterling Homes, indicates that “the subdivision is a demonstration project. The $5.5 million in added cost for the energy efficiency upgrades as well as the energy capture and distribution components is being contributed by various governments through grants. There is no extra cost to the house buyer”.
The Drake Landing residents will pay a monthly energy fee of $60 that is comparable to the natural gas bill they would have incurred in an ordinary home. The energy fee will cover the operational and maintenance costs of the energy delivery system infrastructure.
This level of investment in higher-tech energy conservation does not yet provide a break-even point. It does provide each home owner with the knowledge that they are producing fewer greenhouse gases than their neighbor.
Low-Tech Ideas to reduce Energy Consumption
Low-tech ideas to reduce energy consumption include a high-efficiency furnace, more insulation and windows that reduce heat loss in our generally colder climate. Courtney Oishi, a Program Manager at Climate Change Central, points out that the fastest way to save energy is to “turn lights off when they are not in use, turn down the temperature after hours and increase awareness of energy consumption”.
As natural gas prices at the meter continue to rise, assessing the benefits of these high-tech energy consumption reducing ideas becomes more viable and perhaps urgent.
