The paper discusses the issue of the impact of various energy technologies on public health since the matter is pressing due to the emergence of new ways to harness energy such as waste incineration. The study shows that coal energy, waste incineration, and transport emissions are major hazards to public health. The study reveals nuclear energy is the most environmentally efficient and has the least adverse impact on public health. The paper demonstrates that the use of waste to generate energy is extremely dangerous for public health and can cause emission of polychlorinated dibenzodioxins, which poses a serious hazard. The paper postulates it is uncertain whether waste incineration is beneficial in terms of energy, but it is dangerous for sure. According to the paper, the use of conventional motor fuels is also hazardous due to benzopyrene emissions. Therefore, it is better to use the energy harnessed at nuclear or gas power plants to fir motor vehicles.
