Renewable energy sources can be used as a supplement or a replacement for fossil fuel sources. The most common renewable energy options are solar, wind and hydroelectric. While each of these renewable energy sources are generally more environmentally friendly than burning fossil fuels, there are still limitations and negative impacts of each. Using one of these renewable sources requires understanding the limitations of each type of system and the ability of that system to provide needed power.

Imagine that you are in charge of deciding on a renewable energy source to power your own town. You will research different types of renewable energy sources and will determine your preferred system based on information gathered about the limitations, and benefits of three different types of renewable energy.

Once you have determined your preferred system, you will use that preference to calculate how many homes just like yours can be powered by a given real-world example of your chosen type of renewable energy resource.
