Why do you think Solar energy is more expensive than other energy sources?

• Because it does not generate as much electricity, it is not always dependable, and only effective in certain areas of the country (needs a lot of sunny days)

• Because it is less efficient

• Because the raw materials are rare

• Because it has higher maintenance costs
