The renewable energy alternatives that were presented in the video titled “Alternative Energy” are wind power, solar power, and biomass fermentation. This discussion will describe the challenges and benefits to using alternative power options. Wind power is a system of “windmill” like devices that are made up of turbines and blades. The challenges of using wind power are minimal. The energy produced from wind is sporadic and unreliable because it is not constant. Another issue is that flying animals have been harmed when they have flown into the massive turning blades. Solar power is the use of solar panels which capture sunlight. The challenge of solar power is the number of panels needed and the room they require to produce enough electricity for a city. Biomass fermentation is the conversion of waste, like tree trimmings, leftovers from stems from crops, and sewage waste, into a useable energy converted into liquid fluids and gases. The challenge with this energy is valuable land would have to be converted into factories and the soil would

This is very similar to wind power, but more constant and reliable. Fossil fuels are the main category of nonrenewable energy. Fossil fuels include; coal, oil and natural gas. These resources come from animals and plants that have died millions of years ago and then decomposed to create a useable source of energy for humans. Nonrenewable energy sources have challenges as well. They all cause pollution to the environment when used. In addition, supplies will run out, and these minerals cannot be man-made. The final challenge that they have in common is the harm to land, and the surrounding ecosystems, caused when mining for the required minerals. References Wiley. (2000-2010).
