Questions: Which of the following statements about renewable and nonrenewable energy sources is true? Much of the energy used to power day-to-day activities is in the form of chemical energy. Coal produces 39% of the country's heating and transportation fuel. Nonrenewable energy can be replenished in a relatively short amount of time. In the United States, about 20% of energy comes from renewable energy.

Solution Steps

• The statement "Much of the energy used to power day-to-day activities is in the form of chemical energy" is generally true. Chemical energy is stored in the bonds of chemical compounds and is released in reactions, such as combustion in engines or metabolism in living organisms.

• The statement "Coal produces 39% of the country's heating and transportation fuel" needs verification. Historically, coal has been a significant source of electricity generation, but its use for heating and transportation fuel is less common. This statement may not be accurate depending on the current energy statistics.

• The statement "Nonrenewable energy can be replenished in a relatively short amount of time" is false. Nonrenewable energy sources, such as fossil fuels, take millions of years to form and cannot be replenished on a human timescale.

• The statement "In the United States, about 20% of energy comes from renewable energy" is approximately true. As of recent data, renewable energy sources contribute around 20% to the total energy consumption in the U.S., including sources like wind, solar, and hydroelectric power.
