The answer is:
B) Decrease the cost and increase the availability of solar energy.
This is because if solar energy, which is a natural renewable resource, is cheaper and more available, more people would use it, since they can afford it and have greater access to it. Solar energy can be converted into electricity, which can power cars.
The answer is NOT:
A) Produce cars and trucks that are bigger and more powerful.
(This is because cars and trucks that are bigger and more powerful need more energy to run, since they use more gas to be powered. This actually goes against a solution to our use of fossil fuels.)
C) Develop new legislation to protect our forests from destruction.
(Even though this will help protect our forests, which supply natural, renewable resources, like wood, we do not use wood for powering cars.)
D) Build more energy plants around the United States to fulfill the demands of a growing population.
(Building more energy plants around the United States will not be a solution because energy plants do not use renewable energy. They use resources like nuclear energy.)
