It will be interesting to observe how energy consumption will change following the drastic drop in oil prices. Gas is now $0.73 / L in my neighbourhood! #phys273 #opec

[Morgan Dias-Leclerc @DiasLeclerc]

Overall, the energy sector is the biggest threat to air quality in the world!

[Mike Francis @mikephys273]

Today is a great example of this in Montreal. Extreme weather in April to add to these strange and unprecedented times #lesson11 #covid19

[Sierra D'Ambrosio @DambrosioSierra]

Changes in numerous extreme weather & climate events have been observed since ~1950 #ExtremeEvents #Lesson11

Some facts about hydrogen:
 Most abundant and simple element
 Does not occur naturally
 Found in many organic compounds

[Mike Francis @mikephys273]

Good morning friends, recall that 63% of Canadian residential energy is used for space heating. Let's keep this in mind when turning up the heat in the winter! #lesson9

[Mike Francis @mikephys273]

So interesting. This demonstrates the importance of well-insulated foundations, windows, and walls! Good thing I'm moving out of my parents' basement soon! #lesson9 #lol

[Mike Francis @mikephys273]

@MichaelPhys273 Thank you, Michael.

[Mike Francis @mikephys273]

In many contexts we can think of efficiency as the fraction of energy used that is transformed
into the useful energy we want #lesson9

[Sara Vetere @SaraVetere3]

Fun fact: nuclear power plants account for 11% of the global electricity generation, with OECD countries having approximately 80% of this installed capacity!🤓#NuclearPowerPlants

Radiation: Feel warmth on your face, that’s radiation. It’s
the light that’s coming from the fire that’s hot that you
feel warming your face; which is warming the room. #lesson9

[Mike Francis @mikephys273]

Convection: I heat air, and there’s hot air coming out of
the chimney. Another convection is cool air getting in
through cracks in the windows #lesson9

[Mike Francis @mikephys273]

Conduction: Fire is warming the floor. Anything that is in
physical contact with the fire will have conduction #lesson9

[Mike Francis @mikephys273]

When we discussed the laws of thermodynamics we saw that energy transfer occurs spontaneously form higher to lower temperature bodies #lesson9

[Mike Francis @mikephys273]

Imagine someone from Alberta reduces his electricity use by 3kWh (about the amount of energy
in one pound of coal)

How does that compare with finding an extra pound of coal in the ground? #lesson9

[Mike Francis @mikephys273]

Did not know that! Wow.

[Morgan Dias-Leclerc @DiasLeclerc]

Did you know, the most deadly mean of electricity production is brown coal ☠️ #Phys273

[Mike Francis @mikephys273]

Agreed. I wonder if this is the reason my shower takes so long to heat! #anotherdisadvantage

[Andria Tomao @andria_tomao]

Tankless hot water heater uses powerful heater to heat water on demand
✅Advantage: there is no hot water sitting in a tank losing energy
❎Disadvantages: it is more expensive to buy and install & supply can be limited
#lesson9

[Mike Francis @mikephys273]

Energy production shouldn't be limited to nuclear sources!

[emilie.dupuis @emilied96905995]

Although nuclear energy has 0 GHG emissions, it's important to remember its dangers by learning about the 2 biggest accidents:
1. Chernobyl in 1989: 50-100 deaths immediately + thousands of eventual deaths due to radiation
2. Fukushima 2011: 40ft tsunami, no immediate deaths

[Mike Francis @mikephys273]

Such a great topic!

[Mike Francis @mikephys273]

Incredible!

[Mike Francis @mikephys273]

This is a great point! #lesson8

[Mike Francis @mikephys273]

Have you heard of entropy? @DanielMalouf7 #firstlaw

[Mike Francis @mikephys273]

Is power generation equivalent to electricity generation? #lesson2 #power #energytransfer
