A petro-free home is a building or dwelling that is designed to function without the use of fossil fuels such as oil, gas, and coal. This can be achieved through a variety of means, such as the use of renewable energy sources like solar and wind power, as well as energy-efficient building design and materials. Additionally, a petro-free home might also incorporate sustainable living practices, such as composting, recycling, and the use of non-toxic building materials. The goal is to minimize dependence on non-renewable resources and reduce environmental impact of housing.
Note that a complete petro-free home may not be achievable, as it might be difficult to completely remove all fossil fuel usage from the home, but making significant reduction on the usage and dependence of fossil fuels is the ultimate goal.
Passive solar design: The home is oriented and constructed to take advantage of natural heat from the sun during the colder months and to minimize heat gain during the warmer months. This can help to reduce the need for heating and cooling systems that run on fossil fuels.
Renewable energy systems: A petro-free home may incorporate renewable energy systems such as solar panels or wind turbines to generate electricity and/or provide hot water.
Energy-efficient systems and appliances: The home may be outfitted with energy-efficient systems such as high-efficiency heating, ventilation, and air-conditioning systems as well as Energy star rated appliances.
Sustainable building materials: A petro-free home may use sustainable building materials such as reclaimed wood, non-toxic insulation, and low-emitting paints, adhesives, and sealants. Furniture and other household items made from sustainable materials can help to reduce the environmental impact of the home.
Water conservation: low flow faucets, showerheads, toilets, cisterns and rainwater harvesting can be installed to reduce the use of water from public sources.
Greywater systems: Greywater systems can also be installed to reuse wastewater from sinks, showers and other sources for irrigation, flushing toilets and other non-potable uses.
Avoid products with high embodied energy: Some materials and products, such as those made from plastic, have a high embodied energy, which refers to the amount of energy required to produce and transport the product.
Choose products that are non-toxic: Avoid items that are made from toxic materials and that may emit harmful chemicals into the home.
Avoid products that will have a short lifespan: some of the items that have a short lifespan such as cheap plastics, disposable items, fast-fashion etc. Not only they are not good for the environment but also creates clutter in the home and need to be replaced frequently.
Support local producers and manufacturers: Try to buy items that are made locally, as this can help to reduce the energy required to transport the products.
It can be challenging to build a completely petro-free home, as some fossil fuels may be used in the construction and transportation of building materials, as well as in the manufacturing of appliances and other household items. However, it is possible to significantly reduce the dependence on fossil fuels in the design, construction, and operation of a home. The goal is to minimize the use of fossil fuels as much as possible, and to offset any remaining usage with renewable energy sources.
Designing a petro-free home is a process, and the level of petro-free-ness can be increased over time by making small improvements, upgrades and retrofits to the home. Also, it’s not about being 100% free from fossil fuels, it’s about significantly reducing the dependence and environmental impact.
