Well i always remember never be too cheep.
No. There is no known way to make energy where there was none before. According to Nöther's Theorem, if Conservation of Energy wasn't valid, that would mean that the laws of physics changed over time!
No. It would take energy (pollution) to make them. And also to charge them, assuming you went electric.
Gibbs free energy and standard free energy are both measures of the energy available to do work in a chemical reaction. The main difference is that Gibbs free energy takes into account the temperature and pressure of the system, while standard free energy is measured under specific standard conditions. In chemical reactions, the change in Gibbs free energy determines whether a reaction is spontaneous or non-spontaneous. If the Gibbs free energy change is negative, the reaction is spontaneous, while a positive change indicates a non-spontaneous reaction. The relationship between Gibbs free energy and standard free energy lies in the fact that the standard free energy change can be used to calculate the Gibbs free energy change under any conditions.
YES But only if you don't consider the massive amounts of energy required to make the wind turbine and get it into position. The actual energy conversion from wind to electricity is not great but it is free.
If the temperature is kept uniform in a system, the free energy will remain constant. Free energy, also known as Gibbs free energy, depends on temperature and is a measure of the system's ability to do work. When the temperature is held constant, there is no change in the free energy of the system.
The Gibbs free energy change (∆G) of a reaction represents the difference between the free energy content of the reactants and the free energy content of the products. A negative ∆G indicates that the reaction is spontaneous and can proceed without requiring external energy input.
There are some energy sources, such as wind energy, solar energy, and geothermal energy, that are available in abundance - basically for free. But please note that there is always a cost to convert such energy types into something useful. The energy is free; converting it into useful energy to run machinery is not free.
No
The Big Bang is not an example of free energy. Free energy typically refers to the energy available to do work, whereas the Big Bang was the initial explosion that marked the beginning of the universe and is not related to the concept of free energy.

Energy is not renewable. The sources to make that energy may be. After the initial cost of plant and equipment some sources are practically free so the only costs are maintenance costs..
Spontaneous reactions release free energy. If a reaction is spontaneous, it means that it can occur without outside intervention because the products are at a lower energy state than the reactants, and the excess energy is released as free energy. The change in free energy (ΔG) for a spontaneous reaction is negative.
