D. People who live in wealthier countries tend to consume more energy per person.
Explanation:
People in wealthy countries have access to many technologies such as phones, televisions, and house appliances like coffee makers. All of these use energy. Wealthy people also tend to have larger houses that require more electricity to light and heat/cool. People in developing countries do not have access to these technologies or large houses that consume large amounts of energy.
