Short Answer 
The United States should focus on developing natural resources, particularly renewable energy, to achieve energy independence. Promoting fuel efficiency through the use of fuel-efficient vehicles and implementing supportive policies, such as subsidies and tax cuts, are key strategies advocated by the Democratic Party to reduce oil reliance and enhance sustainability.
Step 1: Develop Natural Resources
The United States should focus on harnessing all of its available natural resources. This includes investments in various energy sectors, particularly in renewable resources such as solar and wind energy. By maximizing natural resource development, the US can work towards greater energy independence and sustainability.
Step 2: Promote Fuel Efficiency
Encouraging fuel efficiency is a crucial step for the US to reduce its reliance on oil. The Democratic Party advocates for the use of fuel-efficient vehicles, which can greatly decrease overall fuel consumption. This not only helps the environment but also reduces costs for consumers in the long run.
Step 3: Implement Supportive Policies
The Democratic Party is actively pushing for government initiatives that support a transition to renewable energy sources and promote fuel efficiency. This includes subsidies for those who use fuel-efficient vehicles and tax cuts for upgrades that enhance energy efficiency. Such policies are designed to incentivize the adoption of sustainable practices nationwide.
