• Use autonomous vehicles.
• Autonomous vehicles typically run smoothly at consistent speeds within cities, preventing excessive fuel consumption and reducing battery power consumption.
• A future with autonomous vehicles may mean fewer vehicles per household, as one vehicle can drop everyone off and pick them up.
• Shift energy reliance to renewables like solar energy.
• Coal-based power plants are a significant source of air pollution and smog generation. By transitioning to renewable energy sources, we can cut down on pollution levels and clear up our skies.

Increase energy efficiency and conserve energy

Energy efficiency and conservation are key strategies in the fight against photochemical smog. This type of smog is a serious issue for urban areas, caused by the release of pollutants from burning fossil fuels, such as cars, power plants, and local industries. Here are some ways to increase energy efficiency and conserve energy to reduce photochemical smog:

Reduce Electricity Usage

Burning coal is the primary source of electricity production, so it is important to reduce electricity usage to lower the amount of pollution created. This can be achieved by turning off lights, air conditioning, and electronic devices when they are not in use. Using energy-efficient appliances and light bulbs can also help reduce electricity consumption.

Switch to Renewable Energy Sources

Solar panels are a great way to generate electricity without creating pollution. They create energy from sunlight, and the only pollution produced is during the manufacturing of the panels. Installing solar panels can help reduce your carbon footprint and decrease the amount of pollution created by burning fossil fuels.

Improve Home Insulation

Proper insulation can reduce the amount of energy needed to heat or cool your home. This includes installing double-glazed windows, sealing gaps around doors and windows, and adding insulation to attics and crawl spaces. By reducing energy consumption for heating and cooling, you can contribute to lowering the demand for electricity generated by burning fossil fuels.

Use Public Transportation or Carpool

Transportation is a major contributor to air pollution. By using public transportation, carpooling, or even walking or biking for short distances, you can significantly reduce your personal pollutant output. Higher occupancy rates in vehicles also reduce the consumption of oil and lower greenhouse gas emissions.
