Biomass Energy Source

Where does your Energy resource come from? How do we get it?

Biomass energy comes from crop animals’ waste and fiber products such as pulp, paper, lumber, plywood, and cotton. We get the energy from biomass by burnings its sources to make heat. This heat produces steam power, which generates electricity.

How is the energy used and transferred? How do we store the energy?

For thousands of years, biomass energy has been used for cooking and heating. An example of this is cooking over a fire itself, or using a fireplace for heat. Today, biomass energy is mostly used to generate heat, electricity, or to liquid fuels for motor vehicles.

Unknown

Do we use a lot of it? If yes, why? If not, why not?

Although biomass energy is often used and is renewable, it can’t be used for a lot. We have not yet discovered how to use biomass energy to power planes or other larger forms of transportation. Because biomass energy is not as dense as other fuels, it does not have enough power.

Are there any social or political issues surrounding it? What is your personal opinion on the use of this resource?

Issues surrounding biomass energy are mainly environmental. Annual harvests o periodic removals of plantsĀ are not sustainable for the environment. Biomass energy also impacts the air quality from it combustion systems.

Questions

For homework tonight, I’d like you to take a look back on all of the simple machine activities we have done thus far. Look at terms like Mechanical Advantage, Work, Effort force, and distances. On your blog (since it’s been a while), ask a few questions about those experiences that you are still confused about! Those will help me to know where you stand. Good luck and see you tomorrow!

One activity that I am particularly confused about it the Ramps and Mechanical Advantage worksheet. I am having trouble understanding exactly how to apply mechanical advantage using the spring scales and ramps. Maybe it is due to the fact that my group had trouble understanding the project, but I remember that once it was explained to me I was able to understand it better. I think I just need to review this specific assignment.
