Which of these energy sources typically produces the most greenhouse gas emissions?

Human activities are responsible for almost all of the increase in greenhouse gases in the atmosphere over the last 150 years. The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation.

What energy source produces the most emissions?

Coal produces more pollution than any other energy source. While coal produces just 44% of U.S. electricity, it accounts for 80% of power plant carbon emissions. Burning coal leads to soot, smog, acid rain, global warming, and carbon emissions.

What are the top three sources of greenhouse gases?

Notes. Globally, the primary sources of greenhouse gas emissions are electricity and heat (31%), agriculture (11%), transportation (15%), forestry (6%) and manufacturing (12%). Energy production of all types accounts for 72 percent of all emissions.

What are the two largest sources of greenhouse gases?

Electricity and Heat Production (25% of 2010 global greenhouse gas emissions): The burning of coal, natural gas, and oil for electricity and heat is the largest single source of global greenhouse gas emissions.

What is the largest source of greenhouse gas emissions quizlet?

The largest source of greenhouse gas emissions is electric power generation. Mitigation strategies in this sector range from carbon capture and storage to replacing fossil fuel based energy sources with renewable sources, including hydroelectric, wind, solar, geothermal, and tidal/wave.

What are the three major sources of greenhouse gas emissions quizlet?

What are the main anthropogenic sources of greenhouse gases? Burning fossil fuels (CO2), agriculture (methane, nitrous oxide), deforestation (increase CO2), landfills (methane), and industrial production of chemicals (chlorofluorocarbons).

How are greenhouse gases produced?

Sources of greenhouse gases

Some greenhouse gases, such as methane, are produced through agricultural practices, in the form of livestock manure, for example. Others, like CO2, largely result from natural processes like respiration, and from the burning of fossil fuels like coal, oil and gas.
