1: capable of being sustained
2 a: of, relating to, or being a method of harvesting or using a resource so that the resource is not depleted or permanently damaged <sustainable techniques> <sustainable agriculture>
b: of or relating to a lifestyle involving the use of sustainable methods <sustainable society>
***I saw a program where a family in New England (very cold climate) used solar cells on their roof for electricity and a geothermal heat pump with a pipes deep into the earth (well) to heat their home. The two systems were expensive but the geothermal heat pump paid for itself in seven years and lasted a long time. They were still hooked to the grid of electricity but over time they used very little fossil fuels.
I do not know how they traveled to work but my guess they used a train of some kind to get to the city.
***
Air craft engines are the most wasteful of fossil fuels, second are the trucks on the roads and third is the individual automobile we have at home.
If we travel by train we cut the aircraft fuel. Trucks can burn natural gas. Some of us can reduce our use of automobiles.
***
Burning our corn and grass (compost) as fuel is wasteful management of our topsoil to produce food and is not sustainable.
***
The home I live in ( by accident) is halfway there to being sustainable. Because my home sits on a water table the earth below our home never gets below 45 degrees which helps heat our home (sustainable).
I use electricity so I break the rule (not sustainable).
I always tell the story that the 1st year we lived in our home it cost us $89.00 for the entire year to heat water, heat our home and cook our meals using natural gas. We have not changed any habits in the last 30 years other than the price of fuel going up. Heating and cooking in our home is sustainable.
