In this article, the general and necessary aspects of ensuring environmental stability, the protection of the environment and biological diversity, the use of natural resources, and the impact of the use of renewable energy sources on the environmental stability of the country are revealed by studying Uzbekistan and international experiences. directed.

Due to rising fuel prices, pollution and climate change, the world's population has become more and more inquisitive about the efficient use of available energy reserves. It is well known that the internal combustion engine in the light passenger vehicles currently in use around the world is very inefficient during starting and stopping periods. To improve efficiency, reduce emissions and reduce operating costs, the possibility of implementing electric drive design as a retrofit of a pre-existing vehicle has been explored by automakers. As you can see, there are a lot of custom made hybrid electric cars on the market. However, there is a lack of retrofit systems for the millions of internal combustion engines that already exist. The design concept presented in this article involves the use of two electric motors specially designed to be installed as hubs for the rear wheels of the car and powered by an on-board battery. Test results are presented in terms of efficiency and economy, leading to comparisons between retrofitted and non-retrofitted designs. The article shows how performance and savings can be achieved by retrofitting in-wheel electric motors to the rear wheels of front-wheel drive vehicles with internal combustion engines..
