it is alternative.

why could you consider the sun ''free enegery''
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.

It is widely used now in the world, but you could consider it an alternative to coal
In your dreams. Also, you could bring a keg of cheap beer to the swap meet at Raceway Park if you consider a keg of beer as free.
True. The minimum Gibbs free energy is not attained by a semipermeable membrane, as the membrane itself does not participate in any chemical reactions that could lower the system's overall free energy. The minimum free energy is achieved through chemical reactions occurring within the system.
Energy is important to consider, because:* We use energy for lots of things, and * It is a limited resource.
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.
For energy to be released in a system, the free energy must decrease. This occurs when the system moves from a higher free energy state to a lower free energy state, typically during spontaneous processes or chemical reactions. The decrease in free energy indicates that the system can perform work or release energy, often in the form of heat or light.
Yes, in the sense of being freely available. For example, the light of the Sun is freely available, as is the wind. That doesn't mean that you can harvest it for free. It takes some technology to convert that to something useful, such as electricity.
