The greenhouse gas problem is real, and potentially a major threat if you listen to some.
Each family can make significant reductions in carbon emissions with some simple actions. The level of reduction depends on the level of effort we are willing to make. I would like to share some of the actions we found work.
If you want to make no changes to your household power usage, but want to produce no carbon emissions, you can sign up to Greenpower with Synergy. This guarantees the equivalent power you use will be produced from wind, solar or other renewable sources. This costs the average house about $3 per week, a small cost to cut all the carbon emissions from the electricity you use.
Some simple changes to the house can reduce energy usage. The biggest impact is insulation in the ceiling (minimum of R3) and in the walls (can even be blown into double brick walls). Both these are ridiculously inexpensive for the improvement they make. Tiling or laying slate on the floors, or having a polished concrete slab add ‘thermal mass’ and help hold the temperature stable in the house. After insulating the house and tiling the floors, our house has maintained a very stable temperature. We only used the air conditioner ONCE this summer, when it was 47c on the back verandah. It also looks like we are going to use a lot less wood this winter. Shading and curtains that seal windows well also reduce heat gain in the house in summer and heat loss in winter.
The hot water heater guzzles energy (electricity or LPG). After installing a water-saving shower head we reduced LPG usage 40%, about $400 per year, and a heap of carbon. Water usage also dropped from 20L / minute to 7.5L / minute in the shower – a bonus.
Other changes require more effort, cost and / or changes to lifestyle. Some examples are;
Solar hot water systems, photovoltaic systems to produce your own electricity (cheaper to sign up to Greenpower), downsize the car, use the car less, get a hybrid car, buy food grown locally (cuts transport), turn off equipment / appliances on standby, and recycle. Many suggestions are on the Government websites and all reduce energy usage.
Each household can make changes to cut carbon emissions. Our household has found it fairly easy, and a lot of fun, to make dramatic reductions in carbon emissions and save some money too.
