The changing political situation of the world has caused a change in the interests of states in the field of economy and energy. Green energy has become one of the biggest areas in which countries compete for several years now. Azerbaijan, as a country that speaks for itself in this field, plans to create green cities in Karabakh.

Given the development of green energy technologies today, is it possible to create cities that only benefit from alternative energy?

Speaking to Ednews on the subject, Hungarian economist Vasa László said that currently the biggest problem in the field of green energy is the storage of energy after its production:

"Supplying cities exclusively with renewable energy is only possible if the issue of energy storage is resolved. After all, the sun doesn't always shine and the wind does not always blow. Storage can be realized with battery-type systems or pumped water power plants. In the case of Azerbaijan, this may be an optimal option in Karabakh.

If the storage is not solved, you definitely need a network, e.g. for energy produced by gas or nuclear power plants. A significant advantage of gas power plants is that they can be operated more flexibly. In my opinion, it is not possible for the time being to supply entire countries with entirely renewable energy, this has not even been achieved in Germany, which has been cited as an example many times.

There is always a need for immediately available energy, in the event that renewables are not able to provide the given capacity. A complete transition is only possible if highly efficient power storage systems are available, but these solutions do not yet exist today."
