Conventional Energy Sources
Conventional Energy Sources refer to traditionally used energy sources that, unlike renewable energies such as photovoltaics, consume finite resources or have harmful environmental impacts.
Fossil Fuels
- Coal, Oil, and Natural Gas: These fossil fuels are the main carriers of conventional energy production. Their combustion releases solar energy stored over millions of years, but it also produces significant emissions of carbon dioxide and other pollutants.
- Nuclear Energy: Although it does not directly cause greenhouse gas emissions, nuclear energy poses risks in the extraction, transportation, and storage of radioactive waste.
Comparison with Photovoltaics
Compared to photovoltaics, conventional energy sources have the following disadvantages:
- Finite Nature: Fossil fuels are limited and will eventually be depleted.
- Environmental Impact: The combustion of fossil fuels leads to air pollution, acid rain, and contributes to climate change. Nuclear energy poses risks to human health and the environment.
- Costs: The costs of fossil fuels are highly volatile and can lead to political tensions.
- Longer Supply Chains: The extraction and transportation of fossil fuels often involve long transport routes.
Reasons for Switching to Renewable Energies
Due to these disadvantages and the increasing importance of climate protection, the expansion of renewable energies such as photovoltaics is being promoted worldwide. Renewable energies are almost unlimited, produce no direct emissions, and can be generated locally.
Conclusion
Conventional energy sources have a long tradition, but their use poses significant risks to the environment and climate. Photovoltaics, as a representative of renewable energies, offers a sustainable and future-oriented alternative.
