Answer. The use and cost of energy affects each of us every day of our lives. Many issues arise from the use of energy: greenhouse gas emissions, acid rain, climate change, dependency on depleting supplies of fossil fuels — especially from politically unstable regions of the world.

The ethical issues of nuclear energy focus on the comparison between the of benefits and the hazards of nuclear power, the catastrophic impact of nuclear accidents, fact disclosure, and safety regulations and violations. These issues have a great effect on global health.

The costs of continuing on our current energy path are steep. American consumers and businesses already spend roughly $700 billion to $1 trillion each year on coal, oil and natural gas, and suffer the incalculable costs of pollution from fossil fuels through damage to our health and environment.

Nuclear energy contributes a very small amount of emissions into the atmosphere which can cause many environmental problems such as global warming. ... Also, nuclear energy produces the same amount if not less greenhouse gasses than renewable resources.

Nine challenges are identified, the most important of which are: lack of transparency, proposal of general criteria, neglection of the main business stakeholder and not introduction of criteria relative to the CSR outcome. Giving attention to the above challenges, a more complete assessment methodology can be made.

Disadvantages of Oil Energy This has been the biggest threat to using oil energy. After combustion, oil releases gases such as carbon dioxide and other greenhouse emissions. These gases are very harmful to the ozone layer as their accumulation encourages its deterioration.

3. Fuel cell life cycle and value chain. As a new energy technology, fuel cells have not yet significantly penetrated the energy market. Cost, durability, and reliability are the main challenges in the commercialization of fuel cells.

Disadvantages of Nuclear Energy The radioactive waste can possess a threat to the environment and is dangerous for humans. We all remember the Chernobyl accident, where the harmful effects of nuclear radiation on humans can even be witnessed today.
