You should call your electric company for an explanation. Basically, without knowing your location, it looks like ECR (Energy Cost & Recovery) provides for the recovery of defined energy cost. It is combined for billing purposes with the charges in the applicable rate and shown as a single line item on the bill to the customer. In English, it looks like the ECR is a way for a utility to recover from unexpectedly high expenses for providing service. There is usually a state commission that has to approve the charge. I found some reference to this being charged to wholesale customers, so you might also enquire about that.
A stationary charged object would experience an electric force field due to other charged objects in its vicinity. The strength of the force field would depend on the magnitude and distance of the other charged objects.
There might be some misconception in the question. Electricity is the flow of energy from translating of electrons. Electricity itself doesn't produce electrons. How an electron as mass emerged from pure energy would required a lot further research in particles physic for the answer.
Not likely - any machine wastes some energy; that would reduce the useful output energy.
Outside a charged spherical shell, the electric field behaves as if all the charge is concentrated at the center of the shell. This is known as Gauss's Law for a spherical surface, which states that the electric field at a distance r from the center of a charged spherical shell is equivalent to that of a point charge with the same total charge as the shell at the center. Therefore, the electric field outside a charged spherical shell decreases with the square of the distance from the center of the shell.
An electric field is a region surrounding an electrically charged object where another charged object experiences a force. It is a vector quantity that describes the direction and magnitude of the force that a positive test charge would experience if placed in the field. Electric fields can be created by static charges, moving charges, or changing magnetic fields.
If electric cars are charged using renewable energy then they are better than hybrid cars, because hybrids still burn some fossil fuels. However, electric cars charged with fossil fuel energy would not be better than hybrid cars.
Potential energy is a energy stored within a system as a result of the position or configuration of the different parts of that system.The types of potential energy are gravitational potential energy, which is energy due to height, and elastic potential energy, which is energy involved with a stretched or compressed spring.
Electric potential is like electric potential energy, except electric potential energy requires that you have at least two charged particles: one charged particle (can be considered to be stationary) to produce the electric field and another charged particle to be affected by that electric field. If both charged particles are positively charged, then when you move the nonstationary charged particle closer to the stationary charged particle, potential energy of the system increases, because the charged particles naturally want to repel. However, let's say you remove that nonstationary charged particle and are left with just the single charged particle. There is no more potential energy in the system, because there is no other charged particle to be acted upon by the electric field. However, the single charged particle still emits an electric field. This field is what creates "electric potential." Even though there is no second particle in the system, if you were to place a second particle into the system (let's call it a test particle), its potential energy would be equal to the electric potential multiplied by the charge of the test particle. U = kq1q2/r (electric potential energy with 2 charges, where the 0 of potential energy is infinitely far away) V = kq1/r (electric potential requiring only 1 charge) V = U/q2 (electric potential is potential energy without the second charge) U = Vq2 (electric potential energy is electric potential multiplied by second charge) There is also a concept called gravitational potential, where it's gravitational potential energy divided by the test mass. It can be a negatively charged particle. In that case, electric potential decreases as you get closer to the negatively charged particle. Even though electric potential decreases, if you have two negatively charged particles, electric potential energy increases as you move the 2nd negative charge closer to the first charge. This is because multiplying 2 negative charges makes a positive: U = k(-q1)*(-q2)/r = kq1q2/r (assuming q1 and q2 are the charge magnitudes) So in this case, it's a little weird because that's how the math works. Nature has a tendency to reduce potential energy, but potential is different and doesn't work the same way. However if the test charge was positive, the sign of electric potential energy will be the same as electric potential with respect to location. V = k(-q1)/r = -kq1/r U = k(-q1)(q2)/r = -kq1q2/r Potential energy is not the same as potential! They are related, but don't get them confused. Energy is measured in Joules. Potential is measured in Volts. Completely different units. Volts = Number of Joules / Number of Coulombs. Electric Potential = Electric Potential Energy / Charge of Test Particle
To increase the electric potential energy of two positively charged particles by a factor of 4, you would need to decrease the distance between the particles by a factor of 2 (since potential energy is inversely proportional to distance). This is because potential energy between charged particles is given by the equation PE = k(q1*q2)/r, where r is the distance between the particles.

Yes, the space around an electrically charged object is filled with an electric field. The electric field represents the influence a charged object exerts on other charged objects in its vicinity. It can be thought of as a region where a force would be experienced by a charged particle placed within it.
A stationary charged object would experience an electric force field due to other charged objects in its vicinity. The strength of the force field would depend on the magnitude and distance of the other charged objects.
Electrical energy is produced through the motion of a conductor within an electromagnetic field produced by a magnet. In this way, electromagnetic fields are absolutely critical to the production of electric energy.
An electric force of attraction would occur between positively and negatively charged particles. Positively charged particles are attracted to negatively charged particles, according to the principle of opposites attract in electric forces.
The space around a charged object in which another charged object experiences an electric force is known as the electric field. The electric field at any point in space represents the force that would be experienced by a positive test charge if placed at that point. It exerts a force on any charged object within its influence.
I really doubt it. If it were, then the strength of the electric field from a charged particle on the far side of the Andromeda Galaxy would be totally unbearable, and it would be completely impossible to stick a charged balloon to the wall in my house.
