Welcome, Everyone! Thank you for joining our last program of 2020!
Kevin McNulty

Transitioning to work deadlines.. Happy New Year everyone!

recyclable not biodegradable, learned that the hard way with my cardboard house model
Jose Lopez
01:12:42
what about nuclear energy?
David Hernandez
01:13:42
sounds like a modern Hobbit Hole
Rick Vaughn, Mentor
01:18:07
Nuclear power reactors do not produce direct carbon dioxide emissions. Unlike fossil fuel-fired power plants, nuclear reactors do not produce air pollution or carbon dioxide while operating. However, the processes for mining and refining uranium ore and making reactor fuel all require large amounts of energy.
Wayne Alldredge
01:22:03
@Jose Lopez: Nuclear energy tends to be classified as 'alternative energy' rather than 'renewable energy'. But I agree with you, its a very clean operating power source.
Ruby Chen
01:22:45
Why is water becoming a controversial issue in California?
Tim House, mentor
01:23:42
@wayne Alldrege, aren
Mark DeMarta- Mentor
01:23:42
20% of energy use in California is used to move and treat water
Tim House, mentor
01:24:20
@wayne - aren't radioactive waste and heated waste water expended in nuclear power generation?
Ruby Chen
01:24:23
How does population make up 2/3 of the water?
Wayne Alldredge
01:25:02
@Ruby Chen: Northern California get 2/3 of all the rainfall, but Southern California has 2/3 of all the people. Water has to be transported from NorCal to SoCal
ChiKwan Fong, Mentor
01:25:05
Nuclear energy is clean energy and carbon free. However, some are concerned about the safety of nuclear power plant operation due to potential leaks.
Maximus Bolwey
01:25:41
I mean have you seen what the leaks have caused or even done
Maximus Bolwey
01:25:45
?
Ruby Chen
01:26:09
How much water do you think needed to be reduced?
Rick Vaughn, Mentor
01:26:45
Would be remiss in my duty as a mentor if I did not share the flip side to Nuclear Energy and did not mention A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes. These materials can remain radioactive and dangerous to human health for thousands of years. Radioactive wastes are subject to special regulations that govern their handling, transportation, storage, and disposal to protect human health and the environment.
Ruby Chen
01:26:46
What are essential ways to reduce water?
Wayne Alldredge
01:28:22
@Tim House: Reactors that were designed in the 50's are the ones that produce waste and expel heated water. Newer Fast Reactors, SMRs, and Pebble Bed Reactors can actually use the nuclear waste from the old reactors as fuel. So, Yes, you're right, but new reactors are more sustainable than those you are referring to.
Tim House, mentor
01:31:11
Thanks Wayne.
Maximus Bolwey
01:31:27
wait what if your taking a shower but only turning on the water when your using. Like turn it off and on depending on when your washing yourself that would be saving a little bit of water right?
Wayne Alldredge
01:32:27
@Maximus. Right! Actually, it saves a LOT of water.
Maximus Bolwey
01:32:58
Good to know I’m doing something right
ChiKwan Fong, Mentor
01:35:03
Reduce consumption activities ( consumption of meat, newspaper, reduce shower time, etc.) that require a lot of water in the supply chain production and manufacturing process
Mark DeMarta- Mentor
01:35:53
BTW plant native milkweed at your house to help save the Monarch Butterfly.
Wayne Alldredge
01:36:21
@Rick Vaughn: Exactly. And that's why nuclear energy is considered 'alternative' and not renewable.
Mark DeMarta- Mentor
01:37:04
The butterfly uses milkweed to lay their eggs
Subrina Kuo
01:37:25
dead zone
Ruby Chen
01:37:48
What are causes of algal blooms?
Jose Lopez
01:38:40
dead zones are the sand looking picture at the bottom left right?
Rick Vaughn, Mentor
01:40:43
Thanks Wayne.
Rick Vaughn, Mentor
01:41:29
@Ruby Chen: Some algal blooms are the result of an excess of nutrients (particularly phosphorus and nitrogen) into waters and higher concentrations of these nutrients in water cause increased growth of algae and green plants. As more algae and plants grow, others die.
Ravi Bajaj
01:41:45
Ruby - algal blooms are typically caused by nutrient overloads in waterways, so even though that algae has benefits, when it overgrows (due to runoff from farms or human waste in the water) then we can get dead zones and competition
Ravi Bajaj
01:42:18
for the questions about dead zones, that photo of sand is likely a precursor to a dead zone. Likely that picture is representing runoff that would eventually lead to a dead zone
Ruby Chen
01:42:30
Thinking back to what I learned about algal blooms in APES last year, I can recall that algal blooms can decrease the fish population in the lake.
Jose Lopez
01:44:33
Janitor is a green career?
Ravi Bajaj
01:45:30
it can be Jose - USGBC LA has a great program on green cleaning
Maximus Bolwey
01:46:00
On the bright side we got to know more about sustainability
Ravi Bajaj
01:46:08
Thanks Ben - great opportunity for folks to get involved through those memberships!
Maximus Bolwey
01:46:25
but we don’t have any time for the rest of the stuff
Flavio Salazar, Mentor
01:46:50
GREAT JOB on presenting everyone!!!!
Wayne Alldredge
01:47:03
@Jose Lopez: Absolutely. The measures taken by janitors today in using sustainable cleaners is extremely important.
Subrina Kuo
01:47:26
what can you do with a student membership?
Ben Stapleton, USGBC-LA
01:47:51
All of members have access to join our committees, access free content like webinars, and more
Kevin Alvarado
01:48:23
by when do you predict we will have 100% renewable energy ?
ChiKwan Fong, Mentor
01:48:58
Membership is good for networking and learning new knowledge from your peers
Fernanda Zuin
01:49:33
@Jose Lopez: please check our Green Janitors Education program for more information: https://usgbc-la.org/initiative/green-janitors-2/
Jose Lopez
01:49:42
is hydrogen a good energy source?
Ravi Bajaj
01:50:15
hydrogen has less greenhouse gas emissions as part of the combustion process - but isn't fully a renewable source
Ravi Bajaj
01:50:25
so it is much better than conventional fossil fuels
Jose Lopez
01:50:35
oh
Fernanda Zuin
01:50:42
And all the USGBC-LA committees and initiatives, ways to get involved can be found on our website: https://usgbc-la.org/

Thank you everyone!
Subrina Kuo
01:51:18
how sustainable is electricity car since many electricity is powered by coal too
Matthew Wong
01:52:07
Could we see solar powered cars in the future?
ChiKwan Fong, Mentor
01:52:50
electricity car reduces the use of fossil fuel which is a major contributor of greenhouse gases
Tim House, mentor
01:52:57
@Matthew Wong - https://www.worldsolarchallenge.org/
Rick Vaughn, Mentor
01:53:46
