Answer: C) Wind Explanation: The energy sources that are constantly being replenished, such as sunlight, wind, and water. This means that we can use them as much as we want, and we do not have to worry about them running out. Additionally, renewable energy sources are usually much more environmentally friendly than fossil fuels. Overall, they release very few chemicals, like carbon dioxide, that can harm the environment. Most of this energy comes from fossil fuels, such as coal, oil, and natural gas. These are nonrenewable energy sources, which means that if we use them all up, we can never get more during our lifetime. Fossil fuels also contribute greatly to global climate change by releasing carbon dioxide into the air when they are burned.

The Interstate Commerce Act of 1887 is a United States federal law that was designed to regulate the railroad industry, particularly its monopolistic practices.   The reason that the Interstate Commerce Act required that rates be published was to avoid secret rebates and similar deals.

Hence, the Act required that railroad rates be "reasonable and just," but did not empower the government to fix specific rates.
