APES Energy Review

Identify ONE specific drawback associated with solar power

• storing solar electricity is cheap and efficient, allowing us to access it at anytime

• the amount of sunlight available to generate solar power is not always consistent (such as night time)

• Solar energy emits large levels of greenhouse gas pollution (CO2, methane, etc)

• Solar panels are cheap to produce, allowing large numbers of people to access the technology

Which of the following best describes the idea of Energy Efficiency

• Using cleaner sources of fossil fuel energy, such as Natural Gas rather than coal

• Switching to renewable sources of energy to reduce greenhouse gas emissions

• encouraging slower consumption of energy to reduce the burden on our electrical grid

• Using less overall energy by switching to devices/technology that does the same work with less power consumption (e.g. LED vs incandescent bulb)

IDENTIFY the proper set up for the word problem written below:

You and your friends go on a road trip to Austin (165 miles away) in a car that gets 30 mpg.  Assuming gas prices of $2.30 per gallon, what is the total cost of gas for the round trip?

•  $\frac{1\ gallon}{2.30\ }\times165\ mi\ \times\ \frac{30\ mi}{1\ gallon}$  

•  $\frac{2.30}{1\ gallon}\times165\ mi\times\frac{1\ gallon}{30\ mi}$  

•  $\frac{2.30}{1\ gallon}\times165\ mi\ \times\frac{30\ mi}{1\ gallon}$  

•  $\frac{2.30}{1\ gallon}\times165\ mi\times\frac{1\ gallon}{30\ mi}\times2$  

A family has an annual electrical consumption of 15,000 kWh. The refrigerator uses 50 kWh per month. What percentage of the overall electricity use does the refrigerator account for?

• .04%

• 40%

• 4%

• .03%

Potential negative environmental impacts of fracking include:

• high levels of nitrogen and phosphorus in run off

• particulate matter (dust) pollution

• CO2 released from slash and burn practices

• methane released into the atmosphere
