Having turbine farms in multiple locations helps ensure that the amount of wind energy being collected is relatively constant at any given time. Less than 40,000 birds are killed annually by turbines while domestic cats are responsible for killing hundreds of millions. Although it is plausible to believe that there would be some local climate change, the overall global effect would be negligible. Because the use of wind power would replace some coal-burning power plants, there would be a reduction the CO2 emissions; this would help to keep the environment clean and therefore reduce temperature change ESET 222: Wind & Solar Energy GHG, GWP and Carbon Footprint A ______ gas (or GHG for short) is any gas in the atmosphere which absorbs and re-emits heat, and thereby keeps the planet's atmosphere warmer than it otherwise would be. The main GHGs in the Earth's atmosphere are water vapor, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and ozone. The main human sources of ______ gas emissions are: fossil fuel use, deforestation, intensive livestock farming, and use of synthetic fertilizers and industrial processes. Global warming potential (GWP) is a relative measure of how much heat a ______ gas traps in the atmosphere. It compares the amount of heat trapped by a certain mass of the gas in question to the amount of heat trapped by a similar mass of carbon dioxide.
