@JeanneLatulippe very helpful! thanks!

@emmaryan3939 coal can cause massive amounts of water pollution because water passing through the mined areas can pick up contaminants ranging from loose soil to highly acidic mine tailings.

@Peter_Phys273 Energy Star certified lighting products produce almost no heat and are resistant to vibration, cutting cooling and replacement costs!

[Alessia Randisi @AlessiaRandisi1]

Newer models of hot air furnace can have efficiencies of up to 60-90%. #Lesson9

@Peter_Phys273 and 63% of Canadian residential energy is used for space heating

[Alessia Randisi @AlessiaRandisi1]

@Vivi_Phys273 an example of heat transfer through conduction is the electric burner of a stove and the bottom of a pan!

[Alessia Randisi @AlessiaRandisi1]

@Vivi_Phys273 38% of heat loss is through cracks in walls, windows and doors!!

@_s0lcito scary to see what Chernobyl has become and the catastrophic effect the accident had!

[Alessia Randisi @AlessiaRandisi1]

@jennciccarello i agree with you on that! Did we just ignore the fact that this waste would need to be stored in a way where it doesn’t distory our planet and the living organisms??

[Alessia Randisi @AlessiaRandisi1]

An “active solar energy” system collects and absorbs the sun’s energy, and uses pumps and fans to distribute the collected heat. #Lesson9

[Alessia Randisi @AlessiaRandisi1]

Did you know that space heating held the highest percentage of distribution of residential energy use by end use in 2013? #Lesson9.

@Vivi_Phys273 wow very interesting!

[Alessia Randisi @AlessiaRandisi1]

this is extremely helpful thanks!

[Alessia Randisi @AlessiaRandisi1]

great visual on renewable energy!

[Alessia Randisi @AlessiaRandisi1]

thank you for providing such an insightful visual! #NetMetering

@RakishanSiva it also contributes to short life expectancies, deforestation croplan degradation and land-use alteration.

[Alessia Randisi @AlessiaRandisi1]

@RakishanSiva Yes! it’s because ocean water is 832 times more dense than air and therefore applies greater force on the turbines. #TidalPower

@AlexToko1 this accident was caused by disabling the safety systems in order to perform tests, during this time the reactor went out of control, overheated and eventually exploded which released a huge amount of radiation and highly radioactive material.

[Alessia Randisi @AlessiaRandisi1]

very interesting!
