Solar, Wind, and Fuel Cell Technology Energy Lab

Full Answer Section

4. • To reduce obstruction
5. More than 50% of the US population lives within 50 miles of a coastline. Therefore, a significant portion of the US population could benefit from offshore wind farm development.

Fuel Cell Technology

7. Fuel cells are currently utilized in:
   • Backup Power for Industrial Facilities
   • Fuel Cell Vehicles
8. The exhaust from a fuel cell is water.
9. Hydrogen gas is fed into one side of the fuel cell and air (which contains oxygen) is fed into the other side. As the hydrogen passes through the layers of the fuel cell, it induces a positive and a negative charge, which generates an electrical current. This process is similar to how a battery works, but instead of using chemical reactions stored within the battery, a fuel cell uses the chemical reaction between hydrogen and oxygen to generate electricity.
10. Individual fuel cells can be stacked together to provide more power. The taller the stack, the more power it generates. This stackability allows fuel cells to be manufactured to scale for a variety of power needs.

I hope this helps! Let me know if you have any other questions.

Sample Answer

Solar Power

1. Solar panels are also called solar photovoltaics or PV for short.
2. Energy from the sun radiates and collides with a semiconductor on a solar panel to produce electricity.
3. Here are 5 advantages of using solar power:
   • Clean Energy
   • No Moving Parts
   • Quiet Operation
   • Water Independence
   • Location Flexibility

Wind Power

4. Two places mentioned where wind farms are located are:
   • California Desert
   • Windy Prairies of Wyoming
5. Wind turbines are tall for a few reasons:
   • To capture more wind
   • To be more efficient
