It is possible to conserve fossil fuels by using less electricity, gasoline, propane and natural gas. Since all of these forms of energy are derived from fossil fuels such as petroleum and coal, it would only make sense that less energy consumption translates to reduced daily fossil fuel requirements.
Fossil fuels are non-renewable energy sources that will not last forever, which is why it is important to conserve them. Some other ways to conserve energy are recycling as much as possible and keeping doors, windows and blinds or curtains closed when using heat during the winter. Using stairs instead of elevators and disconnecting electronics when not in use also help to conserve fossil fuels.
