Question

1. why do you think petroleum use has decreased over the last 30 years? 1 pt

Explanation:

• Renewable Energy Growth: Technologies for solar, wind, hydro, etc., have advanced. These clean energy sources are used for electricity generation, transportation (e.g., electric vehicles), reducing the demand for petroleum as a fuel source.
• Energy Efficiency Improvements: Vehicles have better fuel economy (e.g., hybrid cars), and industrial processes are optimized to use less energy. This means less petroleum is consumed to achieve the same output.
• Environmental Policies and Awareness: Concerns about climate change (due to petroleum's greenhouse gas emissions) have led to regulations (e.g., carbon taxes, emissions standards) and public pressure to shift away from petroleum. Also, the push for sustainable development encourages the use of greener alternatives.

Answer:

There are multiple reasons for the decrease in petroleum use over the last 30 years, such as the development of renewable energy sources (like solar, wind power) reducing reliance on petroleum; increased energy efficiency in vehicles and industries, so less petroleum is needed; and growing environmental awareness leading to policies that promote alternatives to petroleum - based fuels.
