What is one way to reduce the use of nonrenewable energy resources?

Chemistry
1 answer:
omeli [17]3 years ago
3 0

Answer:

By increasing the use of renewable energy sources!

Explanation:

To satisfy the need for power in (whatever country you live in) you need to have a certain quota of power. This is typically achieved by the use of oil and natural gasses. You can also achieve it though by using thermal energy as well as solar energy (Solar Panels), and wind, kinetic, and water. (Windmills and Watermills). These are quite difficult to make and cost a lot of money to produce and kept running smoothly. So to cut back on cost we just use oil/natural gasses. But to answer your question, we need more renewable energy to make nonrenewable energy less used!
