What are the main sources of solar energy?
The only energy we use that doesn't come from the sun is nuclear energy.Any other form of energy, if you track it back far enough, started in the sun.(And it was nuclear energy while it was there.)
Is nuclear reactions a nonrenewable source of energy?
Yes, but if used properly nuclear fuels can provide energy for millions of years before running out, while all known fossil fuels will run out in at most a couple hundred years.
What is difference between potential and kinetic energy give two examples?
If the object is placed at height, it has potential energy and when this object falls down, this potential energy is converted to kinetic (kinesis means movement) energy. If we have to lift object at height , we have to spend energy, witch is released during fall of the object. Example is when water comes down in hydroelectric power station potential energy is converted into kinetic energy. Witch is used to rotate wheel, creating electricity.
Is solar energy more efficient than electrical energy?
The two can't be compared. If you use solar energy, you'll also be using electricity - the electricity from the solar panels (unless you are talking about the other type of solar panel: the one used to directly heat water).
What is the difference between the use of fission as an energy source?
The difference between the use of fission and fusion as an energy source is that in fusion reaction, 2 or more light atomic nuclei fuses to form single heavier nucleus while in fission reaction, heavy atomic nucleus is usually splited into smaller nuclei, other particles and radiation.
Does your body use energy while resting?
Yes
Does A neuron expends energy while it maintains a resting potential?
yes it does
How did solar energy develop as a source of energy?
it become heat and radiate like a nuclear plant produce alot of of energy while your at it
Which has more thermal energy a 5kg bowling ball that has been resting for 4 hours on a driveway or the same bowling ball rolling down an alley in an air-conditioned bowling alley?
the second one because the little friction turns to thermal energy while the first one... no energy transformations are occuring. except potential energy
Why do your bodies use carbohydrates as a source of energy in preference to fats?
The body uses carbohydrates as source of energy in preference to fats because the one reason is that fats are complex substances while carbohydrates are simple and easily available. while in some cases the thyroids hormones save the carbohydrates and uses fats as source of energy.
Is petroleum a energy or a energy souces?
It is a source of energy. Meaning that we can drill for it and then we have it, we don't have to create it. On the other hand hydrogen fuel has energy, but it isn't a source of energy because we can't simply drill for it, instead we have to create it. So while oil is a source of energy, other energy storing compounds like hydrogen fuel are not fuel sources.
How long ago did geothermal energy start being used?
10,000 years ago geothermal energy served as a source of warmth and cleansing while the minerals of geothermal energy was used for a source of healing
Why lighting is not a conventional source of energy?
A conventional source of energy would be one that has been in use for quite a while - say, for a few decades at least, and on a sufficiently large scale. This is not the case with lightning.A conventional source of energy would be one that has been in use for quite a while - say, for a few decades at least, and on a sufficiently large scale.

Describe the four nutritional modes of prokaryotes?
Prokaryotes can be classified into four nutritional modes based on how they obtain energy and carbon sources. Photoautotrophs use light as an energy source and carbon dioxide as a carbon source. Chemoautotrophs use inorganic compounds for energy and carbon. Photoheterotrophs use light for energy and organic compounds for carbon, while chemoheterotrophs rely on organic compounds for both energy and carbon.
Falling electrons are a source of energy?
Please note that, as with all potential energy, that a "falling" electron will provide energy, while "raising" them back to their previous level requires the same amount of energy. It's not really a source of energy, just a way to store small amounts of energy.Please note that, as with all potential energy, that a "falling" electron will provide energy, while "raising" them back to their previous level requires the same amount of energy.

Why does solar energy need a storage device and back up source?
it needs backup source in case there's no sun for a while.
Which has more thermal energy a 5kg bowling ball that has been resting n a hot driveway for 4 hours on a 35 Celsius day or the same bowling ball rolling down a lane in air conditioned bowling alley?
the second one because the little friction turns to thermal energy while the first one... no energy transformations are occuring. except potential energy
