Georgia has a lot of potential to produce power from renewable resources. About two-thirds of Georgia is forested. What type of renewable resource could Georgia most likely produce from the forests?
a
Biomass
b
Hydroelectric
c
Geothermal
d
Wind Energy
a. Biomass. Georgia's forests can be used as a source of biomass energy, which involves burning wood and other organic materials to generate heat and electricity.
Rare earth metals are rarely found in large quantities on Earth. Instead, they are spread very thinly throughout Earth's crust, making them very difficult to get. Once they are all used, they are gone forever. Which energy resource is similar to rare Earth metals in that once it is used up, it is gone?
a
wood
b
solar
c
wind
d
oil
d. Oil. Once oil is extracted and burned, it is gone forever and cannot be replaced within a human lifetime. Similarly, once rare earth metals are extracted and used, they cannot be replenished within a reasonable timeframe.
Windmills are used to harness wind energy and change it into electricity. The wind is an example of which type of energy?
a
inconstant energy
b
created energy
c
renewable energy
d
nonrenewable energy
c. Renewable energy. The wind is a natural, renewable resource that can be harnessed to produce electricity without depleting its source. It is a clean, sustainable source of energy that can be used to reduce dependence on nonrenewable fossil fuels.
What would be the best question to ask in order to immediately determine whether or not an energy resource is renewable?
"Is this energy resource able to replenish itself naturally over a relatively short period of time, not taking more than a few human lifetimes?"
What would be the best question to ask in order to immediately determine whether or not an energy resource is renewable?
a
How long until it runs out?
b
How many people use it?
c
How much energy does it produce?
d
How long has it been used?
a. How long until it runs out? This question can immediately determine whether or not an energy resource is renewable, as renewable energy resources are capable of replenishing themselves naturally and do not have a finite supply. Therefore, they will not run out in the near future.
Which statement gives the best explanation about what will happen to the global oil reserves as time goes on?
a
The global oil reserves will turn into alternative forms of fuel.
b
The global oil reserves will continue to increase.
c
The global oil reserves will remain relatively steady.
d
The global oil reserves will continue to decrease.
