Save Cash, Reduce GHGs and Save the Planet

Reduce energy bills, reduce GHG emissions, save the planet

Can you help save the planet and gain a dollar advantage at the same time? Are you concerned about global warming, air pollution or just your energy costs? Here is a list of things you can do to your home which can cost little and have excellent returns. The list starts from the least costly and is suitable for existing housing.

Typical costs are based on a specific Canadian location in Canadian dollars. They could vary widely. Do your own research and calculations.

Caulking, a cheap way to help save the planet.

Caulk everywhere there is any chance of air leakage

Number one. Caulk, caulk and more caulk. Whether you live in a heating or cooling climate, air leakage is a large energy cost. Caulking is cheap, typically a couple of bucks per tube. Watch for sales. Use paintable or clear product that is suitable for indoor or outdoor use. Fill every crack and space that has even a remote chance of air leakage. This has the added advantage of reducing hiding spaces for insects. If cracks are large, repair or stuff with a suitable material before caulking. Typical cost $10 to $50. The short course on caulking.

Number two. Maintain your equipment. Keep furnaces, air conditioners.refrigeraters and freezers operating at peak efficiency by cleaning heat exchangers and changing filters regularly. Anything that looks like a radiator and has a fan needs to be kept clean as well as any radiating surface. Use metallic tape to seal any leaks in ducting. Arrange furniture so that it has a minimal effect on heat distribution and does not block ducts. Do not install restrictive filters in an attempt to clean the air. They effect efficiency and can damage a furnace. Good maintenance reduces replacement costs. Typical cost for filters is about $25 for a year in colder climates. The best furnace filters to buy.

Number three. Use less cooling or heating. Turn the heat or air conditioning as low as possible if no one is going to be home. Lower the temperature at night in cool climates and use more covers on the beds. Turn heating and cooling completely off if there is no possibility of freezing or other damage. You can do this manually or you can purchase programmable thermostats (or smart controls) that will allow you to raise or lower temperature just before you need it to prevent temporary discomfort. Typical cost $0 to $100. Learn more about thermostats.

Number four. Use less lighting. Make certain everyone in the house turns off lights when not needed. Replace bulbs as they burn out with lower wattage bulbs or replace high usage bulbs immediately with LED or CFL bulbs. Prices are still fairly high for more efficient bulbs but in

LED lights can help save the planet.

LED lights are the new efficient lighting.

many cases the payback time is very rapid. I just bought 4 Led bulbs. 2 were 6w to replace 40 watt and 2 were 10.5w to replace 60w incandescents. My total cost including taxes was $60. You can likely find them for as little as 1/2 that. Pretty pricey but I did a calculation for one much used light. At 6 hours use per day the LED would pay for itself  in 1.5 to 2 years. that’s a good investment in my book. Our electrical rate is $.08 right now and higher rates would effect a higher return. I am very impressed with the LEDs. They are practically instant on. The light is pleasant and at least as good at replacing incandescent as advertised. A 10.5 watt actually gives as much light as the 60w it replaces. Typical costs $0 to $500. I tried to find a good link to information about LED bulb. Everything I could find was outdated. Development in LED technology is proceeding at a lightning pace

Baths use a lot of hot water

Number five. Use less water and heat less water. Showers typically use much less water than baths. A shower can be installed in most bathrooms for as little as $200 if you do it yourself. A new bath spout with a flex hose and shower head along with a shower curtain may be all you need. A tub surround or tiling may be needed as well in other cases. A lot of energy can be saved by doing laundry in cold water and drying you clothes on an outdoor clothes-line when weather permits. A more expensive option is a front load washer. It is worth considering if you have a large family and are replacing your existing unit. When replacing water heaters, consider high-efficiency models. There is really not a typical cost here but some options cost practically nothing while others can run into the thousands.

Sufficient attic insulation can go a long way toward saving the planet.

Number six. Increase attic insulation. In many heating or cooling climates, attic insulation up to about R60 is cost-effective. Have a look. If you have less than 16 inches of insulation you likely have room for improvement. Although a bit of a pain, do it yourself installation is not difficult. Adding 10 inches of loose fill insulation to a 1000 sq. ft. attic can cost under $700. This is an increase of about R30.

Number seven. Basement insulation is important and inexpensive if the space is unfinished. Often neglected is the at the top of walls between floor joists. Insulate to at least R20 and pay close attention to sealing against moisture on the inside. There are several different possible methods of insulating this area with wide range of efficiencies and cost. Necessary in any cold climate but probably not effective in a hot climate.

To help save the planet use use energy efficient windows when replacing.

Number eight. Replacing old windows and doors with new and more efficient ones. This is one I don’t recommend for energy-saving reasons alone. It is very costly and the payback is long. However, if you are replacing for appearance or for functionality, use at least a double paned glass with low E coating. Vinyl or wood frames allow the least energy transfer.

These last two may be out-of-order but costs can vary from very little to very much so I have placed them at the last. They are not always a possible solution in all situations

 Orient your house to take advantage of the sun or shade

Number nine. Consider your home orientation to take advantage of natural, passive heating or cooling. This is easier with a new house, but use of awnings, heavy drapes or cross ventilation can be effective with older homes.

Number ten. Use trees for shading and wind breaks. They also tend to lower the temperature in their immediate vicinity on hot days. They have the added advantage of removing carbon dioxide from the atmosphere. The result is stored carbon and released oxygen. In my area winters are very cold and the prevailing winds are from the north and west. I would plant evergreens to the north and west for windbreaks and deciduous trees to the south for summer shade while allowing sun through in winter. Varieties require careful consideration. Planting large trees can be very costly but  some varieties grow rapidly and can be used while waiting for slower growers to mature. Time is rather irrelevant here as it is the future we are trying to save. Facts about trees.

You can do your bit to reduce greenhouse gas emission and pollution while padding your pocket at the same time. It doesn’t matter if you believe in global warming or not. The cost of fossil fuel and thus energy is bound to escalate in the future, perhaps rapidly. The Idea that recoverable reserves have increased due to technology is misleading. Oil prices have increased 10 fold in recent years in spite of increasing production. We may not be in danger of running out soon, but costs are increasing rapidly.

You may notice that I have not included any alternative power options in this post. That is because it is pretty complicated, especially in our northern climate. Regulations for connecting to the grid vary widely as well. The economics requires a detailed study for each situation. It deserves a post of its own, and I don’t feel qualified to write one, until I have completed a lot more research.
