which of the following renewable energy sources generates the MOST emissions? solid biomass.

Which renewable energy source pollutes the most?

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.

Which renewable energy source produces the most energy?

Hydropower. Hydropower is the most widely-used renewable power source, with the global hydroelectric installed capacity exceeding 1,295GW, accounting for more than 18% of the world’s total installed power generation capacity and more than 54% of the global renewable power generation capacity.

What are the 5 most renewable energy sources?

The most popular renewable energy sources currently are:

  • Solar energy.
  • Wind energy.
  • Hydro energy.
  • Tidal energy.

What are pollutant emissions?

The criteria pollutants are carbon monoxide (CO), lead (Pb), nitrogen dioxide(NO2), ozone (O3), particulate matter (PM), and sulfur dioxide (SO2). There are also a large number of compounds which have been determined to be hazardous which are called air toxics. Sources. There are many sources of emissions.

What is the biggest contributor to CO2 emissions?

Energy consumption is by far the biggest source of human-caused greenhouse gas emissions, responsible for a whopping 76% (37.2 GtCO2e) worldwide. The energy sector includes transportation, electricity and heat, buildings, manufacturing and construction, fugitive emissions and other fuel combustion.

What causes CO2 emissions?

Carbon dioxide emissions mainly come from burning organic materials: coal, oil, gas, wood, and solid waste. … Agriculture and livestock, including fertilizer, manure, and burning of agricultural residues, along with burning fuel, are the biggest sources of nitrous oxide emissions.
