Fossil Fuels
Give JUST TWO examples of fossil fuels
oil, coal, gas
Why is solar power considered RENEWABLE?
Since the sun will be giving off solar energy for billions of years, it is renewable
Is water (hydroelectric) energy renewable?
Yes, as long as the water keeps flowing and as long as there is more rain and snow.
What do we need to dig up out of the ground to make atomic (nuclear) fuel? It's a rare kind of rock. Starts with a letter "U."
Uranium
What has a face and two hands but cannot smile or hold anything?
A clock.
Accidental spills or leaks of oil or gas during pumping or transportation of this fuel is:
a) an upside
b) a downside
c) neither
b) a downside
Name TWO DOWNSIDES of solar power.
If it is cloudy, you cannot collect solar energy.
Solar panels are expensive and making them produces pollution.
When building solar thermal power plants, you need to use up a LOT of land to place reflectors (mirrors).
Name two UPSIDES to water (hydroelectic) energy.
It is renewable (as long as there is enough rain and snow melt).
Because rivers flow all the time, dams that have hydroelectric turbines can always produce electricity.
Once dams are made, they are relatively inexpensive to operate.
What is one DOWNSIDE of atomic (nuclear) power?
Uranium is not renewable. Once it's used up, it's not useful to make electricity and you need to keep it safe because it's still radioactive.
If I want to add an "-s" to the word, "try" how do I spell it?
Example: "My brother _______ every day to help out mom."
tries
It's less expensive than other sources of energy.
or
It's one of the most reliable sources of energy.
When is one time when you cannot use solar panels?
At night or when it's cloudy.
Is water a natural resource or not?
Yes, water is a natural resource.
What is one UPSIDE to atomic (nuclear) power?
Atomic power does not produce pollution.
You only need a small amount of uranium fuel to make LOTS of power.
(Remember, half of one train car of uranium fuel per YEAR versus 82 train cars of coal every DAY?)
It’s raining at midnight, but the forecast for tomorrow and the next day is clear.
Will there be sunny weather in exactly 48 hours?
No, it won’t be sunny because it will be dark out. In 48 hours, it will be midnight again.
Why are fossil fuels considered NONrenewable sources of energy.
What are you going to do then? Wait another million years for plant and animal material to turn into coal and oil?
If I have solar panels on my house for electrical energy, will I STILL need ANOTHER source of electricity, or can I just use solar panels alone?
You will probably need ANOTHER source of energy.
Solar panels alone probably won't be enough.
Choose one of these to answer:
1) When you make a dam to create hydroelectric power, does it affect the environment or not?
2) Can dams have problems?
1) Yes it does. You stop up the river and sometimes fish cannot swim past them.
2) Yes, from the book, "Blackout!" there was a dam in Russia that had cracks form in its walls
We put uranium fuel rods in a nuclear reactor. We use control rods to control the nuclear reactor. So, what does the heat from the reactor do? What is that heat good for?
You must use these words: WATER, STEAM, TURBINES, MAGNETS, ELECTRICITY
The heat from the reactor turns WATER into high-pressure STEAM that turns TURBINES and the turbines turn MAGNETS in an electrical generator and that makes ELECTRICITY.
It belongs to you, but your friends use it more.
What is it?
Your name.
Could we live in the suburbs like Apple Valley, use large amounts of electricity like we do, drive in cars and other vehicles, get food from the grocery store, all WITHOUT fossil fuels?
Yes or No ?
NO.
Name 3 ways that the electrical power grid can be caused to go down. This is called a blackout.
1) A heat wave causes too much electrical demand because too many people are using their air conditioners.
2) A power line has been broken or severed.
3) The power plant that makes the electricity runs out of the thermal fuel (uranium, coal gas) that the power plant uses to make high-pressure steam.
4) A dam fails because of poor construction or design or because of a water shortage.
If there is not enough water flowing in a river, then the dam won't get enough water flowing through its turbines to spin the magnets to make the electricity.
Spell this word.
