Reasons for carbon-free resources and viewing conventional energy supply on the results of a research

Abstract

The consequences of climate change are among the greatest challenges of the 21st century. The global average temperature will rise by more than 2.5 C, which will increase the number of starving people by over 80 million. 25% of mammal species and 12% of bird species are projected to be extinct. The Earth's population is currently over 7.5 billion people, growing steadily. It also means a steady increase in the energy demand of the population. The greenhouse effect, which causes global warming, is primarily responsible for climate change. According to a NASA report, the rate of warming is faster than that of any previous modeling, so the greenhouse gas emissions must be drastically reduced to slow down the process. Each year, 6 billion tonnes of CO2 emissions come from fossil fuel emissions and 1 billion tonnes from land use. According to the University of California, CO2 emissions are distributed as follows: transport 49%, electricity generation 30%, industry 11%, population 7%, trade 3%. The aim of the study is to present the knowledge and opinion of the respondents about the classification of conventional energy sources and how long the Hungarian carbon / lignite stock may be sufficient.
