17. How is the majority of electricity generated in the area where you live? Does the process involve the combustion of coal? Check with yout teacher if you are not sure. 18. Many of the carbon-based fuels are categorized as fossil fuels because they formed from decayec organisms over millions of years. List as many examples of fossil fuels as you can. 9. How does our use of these carbon stores affect the amount of CO , in the atmosphere?

In many places around the globe, electricity is primarily generated through fossil fuels, such as coal, natural gas, and oil. The combustion of these fuels releases energy, which is then converted into electricity. For areas still relying heavily on coal, this process can produce high levels of CO2 emissions, contributing significantly to climate change. Transitioning to cleaner energy sources, like solar or wind, is becoming a key focus to reduce these emissions. Fossil fuels include a range of carbon-based energy sources that have formed over geological timescales. Some common examples are coal, natural gas, crude oil, and peat. Additionally, shale gas and tar sands, although variations on natural gas and oil, are also considered fossil fuel sources. As we tap into these reserves for energy, we're releasing stored carbon into the atmosphere, which adds to the greenhouse effect and plays a major role in global warming.
