Today people use fossil fuels along with alternative energy sources. This is because as populations grow, the higher demand for energy uses up nonrenewable resources. Reducing the use of fossil fuels would have a positive impact on the environment. However, even with advances in technology, alternative energy sources still have some limitations. What limitations affect many forms of alternative energy sources? Choose the three that apply.
A. cannot be used everywhere
B. cannot generate energy in large enough amounts
C. can be costly to set up initially
D. are difficult to use
E. affect habitats
