By far the most concerning and talked-about of these compounds is CO2. Because carbon accounts from between 60 to 90 percent of the mass of the fossil fuels burned, CO2is the principal product of the combustion of fossil fuels worldwide. China has become the largest emitter of CO2on the p...
Hydropower is a renewable energy source, and it is generated by the fast flow of water, whereas fossil fuels are burned to generate electricity. Thus, hydropower is not only feasible but also environmentally friendly. #3 Affordable Source of Energy The cheapest and most feasible source of energy...
Fossil fuels are non-renewable and finite. Once we run out, they’re gone. They are also a leading contributor to carbon emissions. When fossil fuels are burned, they lead to a net release of carbon dioxide. A renewable source like wood is part of a carbon lifecycle of absorption and em...
The acidity of rain and snow can lower the pH of the groundwater that enters the soil.By burning fossil fuels such as coal,oil and gasoline,humans have been contr ibuting to higher levels of acidity in many soils.When fossil fuels are burned, gases are released into the air and then fa...
When the fuels are burned at power plants, electricity is made for homes. But power plants make the air un- clean when they are hurned because fossil fuels give of harmiful gases. As a result, these gases pollute the air, mak- ting it harmful to breathe. What's more, these harful...

Fossil fuels are made from decomposing plants and animals. These fuels are found in the Earth’s crust and contain carbon and hydrogen, which can be burned for energy. Coal, oil, and natural gas are examples of fossil fuels. Coal is a material usuall...
The climate change in Australia causes many problems due to the fossil fuel are burned. First of all, the climate change increases the frequency of extreme weather events, such as the spring of 2013 has been Australia’s warmest on record. The temperature for the season was 1.57°C above ...
①Fossil fuels such as coal, oil and natural gas are burned in large quantities in industries, vehicles and household stoves, producing large amounts of carbon dioxide. ② Deforestation(滥伐森林), especially in the tropics, has led to a rapid reduction in the amount of carbon dioxide absorbed...
