2 Its cost effectiveness (does it help reduce the cost of energy in a community)
3 How easy it is to harness this source of energy
4. Whether or not using this resource is harmful to the environment (sometimes wind turbines kill wildlife and scare cows lol)

Sunlight is the main source of energy on earth
the source of energy causing the wave is vibration.
Our main source of energy is the light and heat from the Sun.
Nope the sun is the earths main source of energy
Voltage and resistance determine amperage, assuming the source can provide the amperes.
its dangerous
An alien energy source depends on what kind of alien it is and whether their equipment is futuristic or not. Note that aliens have not been proven to exist.
The distance from origin, and the composition of the source material.
1st. how hot is the heat source 2nd.the distance between the object and the heat source 3rd.whether if the object is a good conductor of heat (tht's not the answer. u wanted i guess)
