a. it has led to the complete removal of traditional energy sources like coal and oil.

b. it has been a new science that is used sparingly and is still being explored.

c. it has changed how many people and businesses have consumed energy.

d. it has been too costly to maintain and the u.s. has gone back to using more traditional energy methods.

Explanation:

• Option a: Traditional energy sources like coal and oil are still used in the US, so "complete removal" is incorrect.
• Option b: New energy sources (e.g., solar, wind) are increasingly used, not "sparingly" only.
• Option c: New energy sources (renewables) have changed energy consumption patterns for people (e.g., home solar) and businesses (e.g., corporate renewable projects), so this is correct.
• Option d: The US is investing in new energy, not "going back" to traditional methods; costs of new energy are decreasing.

Answer:

c. It has changed how many people and businesses have consumed energy.
