Not exact matches

Some experts say that coal - fired plants can only become truly clean if the government and industry pump billions of dollars into the technological upgrades required to extract the carbon dioxide gas created during combustion and sequester it semipermanently deep underground.

Similarly, coal contains trace amounts of mercury, which is set free during combustion at power plants.

Human emissions however are on the decline in many countries due to more strict pollution controls on power plants like burning low - sulfur fuel and technological advances to remove it during and after combustion.

This is because the amount of CO2 released from E85 during combustion is practically identical to the level of carbon dioxide the plants absorbed from the atmosphere through photosynthesis when they were growing.

Impacts of California's Five - Year (2012 - 2016) Drought on Hydroelectricity Generation — This comprehensive assessment of the costs to California of lost hydroelectricity during the five - year California drought (from October 2011 to the end of September 2016; the official California «water year» runs from October 1 to September 30) reveals an increase in electricity costs of approximately $ 2.45 billion, as well as a 10 percent increase in the release of carbon dioxide from California power plants due to the additional combustion of fossil fuels for electricity generation.

Preheating combustion air with waste heat from the plant will also increase efficiency, and some plants are considering schemes to use solar thermal collectors as air preheaters during daylight hours.

During the past 500 years or so, human activities have released mercury from its relatively stable and water - insoluble form (cinnabar) in rocks and soil through mining, fossil fuel combustion, and other activities, and so have increased the portion of mercury that is actively cycling through the atmosphere, surface waters, plants, and animals as it changes chemical and physical form.
