One of the most complex structural transformation processes currently unfolding in Europe is the phase-out of coal mining and coal-fired power generation. This transition is embedded within the broader framework of international and European climate commitments and the ongoing energy transition, particularly under the environmental policies promoted by the European Union and the European Green Deal. The process entails profound economic, social, technical, and geopolitical implications, especially for single-indus...

In line with global trends and concerns regarding pollution and climate change, the transition towards non-polluting energy sources is on the rise, favoring clean/renewable energy while reducing reliance on fossil fuels, particularly coal. This shift is essential for lowering carbon emissions and mitigating climate change. Governmental efforts, through policies and regulations (such as carbon taxes and subsidies for renewables), focus on decarbonizing the energy economy. Meanwhile, companies are investing in renew...

The climate, energy, and health crises, alongside the conflict events in Eastern Europe, have generated new directions regarding the perspectives of global and national energy transition, by orienting it towards a decarbonized economy. The increased frequency of climate change-related weather events affects the availability of renewable energy sources (wind and solar) and energy supply security. The abandonment of fossil fuel-based electricity and heat due to commitments and objectives established in the United Na...

Multiple crises in recent years, including the health crisis caused by the COVID-19 pandemic, the global energy crisis, the climate crisis, the decarbonization of the energy mix, the European Green Pact, the energy transition, the conflict in Ukraine, and the energy trilemma, have created the conditions for a new energy revolution. If the listed influencing factors, the sanctions imposed on Russian oil and gas as well as the confrontation with the components of the trilemma, energy security, minimal impact on the ...

The use of pneumatic energy in industry as well as in the tertiary system is quite frequent representing 10% of the industrial electricity consumption in the European Union, the life span of compressors being relatively long, namely between 14 and 16 years depending on the installed power. Although the compressed air demand of a coal mine is covered by performant compressors manufactured by well-known producers there still are multiple possibilities to increase their energetic efficiency. The working method is con...
