Which is an advantage to using nonrenewable resources

Answers

The main advantages of non-renewable energies is that they are abundant and affordable. For example, oil and diesel are still good choices for powering vehicles. Non-renewable energy is cost effective and easier to product and use. According to National Geographic, there are reservoirs of non-renewable energy sources throughout the world. Hope this helps!

Final answer:

Nonrenewable resources like oil, natural gas, and coal are efficient and economically viable due to established infrastructure. However, they have environmental impacts and are finite.

Explanation:

The question asks about the advantages of using nonrenewable resources. Nonrenewable resources such as oil, natural gas, and coal, have several advantages. One significant advantage of nonrenewable resources is their efficiency. These types of resources are often much more efficient in generating energy than renewable alternatives. For example, a small amount of coal or nuclear energy can produce substantially more energy than solar or wind power. Furthermore, nonrenewable resources are currently more economically viable. The infrastructure for extracting and using these resources is well established, making them cheaper to use in the short term as compared to renewable sources. However, we need to be aware of the environmental impact and the fact that these resources are finite and will eventually run out.
