Discuss US Green Building Council LEED-Green-Associate Exam Topic 1 Question 12

Which of the following Is a source of green power?

AClean coal

BWind turbine

CNuclear fission

DNatural gas captured by hydraulic fracturing

Suggested Answer: B

A wind turbine is a source of green power, which is electricity generated from renewable sources that have low or zero greenhouse gas emissions. A wind turbine converts the kinetic energy of the wind into mechanical power, which can then be used to generate electricity. Wind power is a clean, abundant, and sustainable form of energy that does not produce air pollution or contribute to climate change. According to the U.S. Department of Energy, wind power accounted for about 8.4% of the total U.S. electricity generation in 2020. The other options are not sources of green power, as they either rely on fossil fuels or nuclear energy, which have significant environmental and social impacts. Clean coal is a term used to describe technologies that aim to reduce the emissions and waste from burning coal, but it is still a carbon-intensive and polluting source of energy. Nuclear fission is a process that splits atoms to release energy, but it also produces radioactive waste that poses long-term health and safety risks. Natural gas captured by hydraulic fracturing, or fracking, is a process that injects water, chemicals, and sand into underground rock formations to release natural gas, but it also causes water contamination, air pollution, and seismic activity.Reference:LEED v4 Reference Guide for Building Design and Construction, p.3471; [U.S. Department of Energy website]

Natural gas from fracking? That's a stretch for green power.

Marylou 11 months ago

Wind energy is super clean and renewable!

Josefa 11 months ago

Wait, is nuclear really considered green?

Dino 11 months ago

Clean coal? That's not green at all!

Anabel 12 months ago

Wind turbines are definitely a source of green power!

Huey 12 months ago

I feel like I’ve seen practice questions where wind energy was always the right answer. I hope that holds true here!

Lauran 1 year ago

Clean coal? I thought that was a bit of a contradiction. I’m leaning towards wind turbine for this one.

Lai 1 year ago

I remember studying about renewable energy sources, and wind power was highlighted as a key example.

Jina 1 year ago

I think wind turbines are definitely a source of green power, but I'm not completely sure about the others.

Lisha 1 year ago

Wind turbine is definitely the way to go. Renewable energy sources like that are the key to green power.

Nelida 1 year ago

Clean coal? I don't think that counts as green power. I'm leaning towards wind turbine or nuclear fission.

Celestina 1 year ago

Wind turbine seems like the obvious green power option here. I'm pretty confident that's the right answer.

Mirta 1 year ago

Hmm, this one's tricky. I'll need to think carefully about what qualifies as a "green power" source.

Kizzy 1 year ago

I'm a bit confused on this one. I know nuclear fission isn't considered green, but I'm not sure about the other options. Guess I'll have to eliminate the ones I'm sure aren't right.

Resetting the Active Directory user's password could be an option, but I'm not sure that's the best approach. The question doesn't indicate there's an issue with the user's credentials, so that might not be the solution.

Asha 1 year ago

Hmm, I'm a bit unsure about this one. I'll need to review the scrum principles and think through the potential impacts.

Fanny 2 years ago

I believe natural gas captured by hydraulic fracturing is not a source of green power, as it has negative environmental impacts.

Isadora 2 years ago

Nuclear fission could be considered green power too, as it doesn't emit greenhouse gases.

Lou 2 years ago

I agree with Shawnta, wind turbines produce clean energy.

Shawnta 2 years ago

I think a wind turbine is a source of green power.
