Abstract
In today’s World, energy has a crucial importance for all countries. The countries search for both new energy resources and how they can use them. Energy resource is an important problem in our country, too. It is the sign of how it is important that we are mostly foreign dependent on energy. The most important energy problem is energy efficiency. When changing and developing automotive industry is handled, an important part of energy consumption consists of automobiles. So, it is clear that even small scale efficiency studies can save energy when thought in general basis (all automobiles). Practical solutions about efficiency increase in present vehicles, electrical efficiency and structure of vehicles working with energy taken from the sun is analyzed in our study.
