How was the production of mercury from burning coal an environmental hazard?
How is the production of mercury from burning coal an environmental hazard? Mercury in water systems is transformed through biological processes into a substance that is toxic to animals.
Which energy source causes the greatest waste disposal concerns?
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.
Which energy sources does not produce carbon dioxide?
Most renewable energy sources are carbon-free. This means that they do not emit any carbon dioxide when they generate energy. Solar, wind, and hydroelectric are carbon-free. Nuclear, though not renewable, is also considered a carbon-free energy source, because unlike coal and natural gas, it does not burn.

Why hydropower is not clean energy?
Hydropower dams and reservoirs emit methane, a greenhouse gas that is 20 times more potent than carbon dioxide. These emissions are caused by the decomposition of organic vegetation flowing into the water as the reservoir levels fluctuate, and as rivers and floodplains are flooded each year.
What are advantages of hydropower?
Because hydropower plants can generate power to the grid immediately, they provide essential back-up power during major electricity outages or disruptions. In addition to a sustainable fuel source, hydropower efforts produce a number of benefits, such as flood control, irrigation, and water supply.
How has technology benefited energy production?
How has technology benefited energy production? a. It has provided for the use of alternate energy sources that have reduced impact on the environment. … It has allowed for the improvement of existing methods of producing energy.
Which of the following energy sources does not produce carbon dioxide quizlet?
Nuclear, solar, and geothermal energy are all low sources of air pollution and do not emit carbon dioxide into the atmosphere. Nuclear and geothermal energy both heat up water to produce electricity.
How are resources allocated quizlet conservation?
How are resources allocated? Resources are allocated according to demand and monetary resources. Countries with high demand of resources and the ability to pay for them are more likely to end up with needed resources.
