Start with the petroleum your household actually uses: gasoline or diesel for travel, heating oil if your home burns it, and disposable petroleum-derived products. Reduce routine driving first, then address home energy, gas-powered equipment and single-use plastics. The best steps depend on your vehicles, heating fuel, local transit and recycling rules.
Start by identifying where petroleum enters your household
In U.S. households, petroleum is most visible in gasoline and diesel transportation fuel, heating oil used in some homes, and petroleum-derived plastics and other products. Lowering energy use does not always mean lowering petroleum use: for example, reducing electricity use cuts petroleum directly only to the extent that petroleum is part of the electricity supply.
Make a short inventory before buying anything: note your household’s typical driving, the fuel used by your heating system, any gas-powered yard equipment, and the disposable plastic products you regularly use. This helps prioritize changes that displace something your household actually consumes.
Cut petroleum use in everyday travel
Reduce or combine car trips
EPA’s guidance is simple: “Fewer miles driven means fewer emissions.” Walk or bike for feasible trips, use transit or carpool where available, group nearby errands, and telework when your job allows it. Avoid unnecessary idling; EPA says modern vehicles do not need to idle to warm up before driving in winter. See EPA’s vehicle and engine pollution guidance and its transportation climate tips.

- 【TwinCell Anti-Shading Design】The Callsun 200W solar panel features a dual-module parallel design that divides the panel into two independently operating sections. When one section is partially shaded by trees, buildings or other obstacles, the other section can continue generating power. This design helps reduce the impact of partial shading and maintain more consistent energy production.
- 【Compact Design for RVs, Vans & Off-Grid Use】Each panel measures 51.3 × 30.3 × 1.4 inches and weighs 23.8 lbs, delivering strong power output in a compact footprint. This 200W solar panel is ideal for Class B vans, RVs, marine applications, rooftops and other space-conscious off-grid solar systems. Pre-drilled mounting holes make installation with compatible mounting hardware straightforward.
Do not assume rideshare automatically saves petroleum. It is more likely to help when it replaces a trip you would otherwise make alone; routing, detours and how many passengers share the vehicle affect the result.
Make your next vehicle fit your actual trips
If you are replacing a vehicle, compare fuel-efficient models and electric options. Consider your typical daily distance, charging access, upfront and operating costs, local climate and terrain, and whether an option fits your household’s longer trips. EPA recommends considering fuel-efficient and electric vehicles, but no one option is best for every driving pattern or location. See EPA’s information on greener vehicles.

Reduce home energy demand—and check your heating fuel
EPA recommends sealing air leaks, adding insulation where appropriate, using weatherstripping and door sweeps, maintaining equipment, and adjusting heating and water settings. These steps reduce energy demand; they directly reduce petroleum use when petroleum is the fuel being consumed, such as heating oil. Many homes instead use natural gas, propane, electricity or another source.
EPA’s general guidance suggests setting the thermostat to 68°F during the day and 60°F at night, and setting the water heater to 120°F. EPA says lowering water temperature can reduce water-heating costs by 6–10 percent; that is a general estimate, not a guaranteed result for every home. Comfort, health needs, climate and equipment instructions matter. Consult EPA’s home energy-saving tips.

If your home uses heating oil, lowering heat demand can directly cut petroleum consumption. Replacing an oil-burning system may also reduce it, but system choices require a qualified assessment of the building, climate, electrical service and local utility conditions. Do not assume a furnace burns oil without checking its fuel source. EPA also warns: “Never use a gas stove to heat your home.” See EPA’s combustion-products guidance.
Choose lower-petroleum yard equipment when replacing it
For a small lawn, EPA recommends a manual reel mower. If you need powered equipment, consider electric or battery-powered alternatives to gas-powered machines. These are replacement choices for when equipment is due—not a reason to discard a working mower. Battery equipment uses electricity for charging, so it should not be described as petroleum-free across its full supply chain. EPA’s transportation and engine pollution guidance discusses alternatives to gas-powered landscaping equipment.

Use less disposable plastic through reuse and repair
Reuse containers and other items you already own, repair products when practical, and skip disposable utensils when they are unnecessary. Reducing and reusing avoids demand for new materials; buying additional containers is not always necessary. When disposing of plastic, check your local waste authority’s accepted-material list. Recycling rules vary: some film plastics require store drop-off rather than curbside collection, and compostable plastics can disrupt conventional recycling if placed in that stream. A recycling symbol alone does not guarantee acceptance in your household program. See EPA’s reducing and reusing guidance.

Prioritize changes by what they displace
For each possible change, ask what petroleum fuel or product it replaces, how often you will use it, its upfront and operating costs, local access and infrastructure, maintenance and service life, and—if it uses electricity—the role of the local grid. These checks help distinguish a practical petroleum reduction from a change that merely shifts energy use or adds a purchase.
