How much % of sunlight is converted to air mass movement
2%
Is wind power becoming a much more popular way of converting energy?
Yes
Where are wind farms/mills widely used
Netherlands and throughout Europe
What are 7 pros of wind power
a) Free to run
b) Clean energy
c) Infinitely renewable
d) Doesn’t use much land
e) Safe to operate
f) No need for water
g) Fits into the current power grids easily
What type of solar power is wind power?
Indirect
What are 3 cons of wind power?
a) Need wind
b) Need storage and back up systems
c) Windmills can be eyesores
In 2015, ____% of Denmark’s power share came from wind power
43%
Norway gets nearly _____% of power from hydro-electric
100%
Canada gets around ___% of power from hydro-electric
60%
What are 3 pros of Hydro
a) Low CO2 produced
b) Fits the current electrical grid
c) No need for new technology
What does hydro produce low CO2 instead of no CO2
Because to create a dam, they have to flood part of the area which kills a lot of organisms which in turn then decompose and dispense CO2
What are 4 cons of Hydro
a) Flooding
b) Land use
c) Good area are already occupied
d) Sediment
Where is the largest dam in the world located? How high is it and how wide is it
Located in China, it is 400m high and over a kilometer wide
What are the three main types of biomass
a) Alcohol
b) wood
c) Waste
What type of biomass is the currently the most common
Alcohol
Is biomass currently a solution to switch too from fossil fuels? why or why not?
No because we need more scientific discoveries to make biomass more efficient
What are 2 other ways of getting power?
a) Geothermal
b) Tides, waves, etc.,
What is net metering?
When hydro meters have the ability to run both forward and reverse depending on if electricity is being used or generated. The excess energy flows into the provincial power grids
True or False; in Manitoba meters can pass 0 resulting in Manitoba Hydro sending you a check instead of a bill?
False
What are two examples of energy storage?
a) Load levelling generation
b) Hydrogen
What is one example of energy conservation
a) Co-generation
What are the top 2 sources of energy is Manitoba and how much % of Manitoba’s energy comes from these too?
Electricity and natural gas.
95%
What are the other, minor ways Manitoba creates energy
a) Propane
b) Fuel oil
c) Gasoline
