Exploring Electrical Power: Uses, Sources, and Impact of Coal

Discover the various uses of electrical power in homes, from lighting to cooking, and the significant role coal plays in generating electricity globally. While coal is abundant, it raises concerns about carbon emissions. Dive into the science behind coal formation, electricity generation, and environmental impacts. Explore the positives and negatives of electricity, including its renewable potential and limitations in range and power. Gain insights on where electricity is used globally, such as in power plants across countries like China, the USA, Russia, and India. Uncover the CO2 emissions associated with coal-generated electricity and the environmental challenges it poses. Access helpful bibliographies for further reading on coal power and electricity generation.

  1. Electrical Power COAL

  2. The Uses • Power for homes • Light bulb • Toasters • Microwaves • Some cars • Batteries • heating, • cooling, • cooking, • refrigeration, • light, • sound, • computation, • entertainment...

  3. Renewable? • Electricity is only renewable if it is not generated from fossil fuels or nuclear power. If generated by wind, water or solar power then it is renewable. • Coal is the world most abundant source of fossil fuel • Coal provides over 22% of the commercial energy used in the world • Nonrenewable in our life time

  4. Cost • The energy information administration gives charts of revenue from retail sales of electricity to ultimate customers • http://www.eia.doe.gov/cneaf/electricity/epm/table5_2.html

  5. Positive • Electricity can be generated by a renewable source • Efficient, clean and quiet • Zero vehicle emissions • Electric grid in place, we won’t have to invest in new technology

  6. Negative • Limited Range and Power • Batteries are expensive • Slow in the refueling process (6-8 hours) • The power plant emissions can be harmful if generated by coal or oil

  7. Science Behind the Curtain • Coal forms in several stages • When coal ages, it’s carbon content increases and the water decreases • Electricity has been around for a long time, always in the atmosphere • Hydro, solar, geothermal, wind, nuclear, coal • Transported by trains and kept in a processing plant • Coal mining is dangerous and can kill people due to diseases like black lung • Smoke stacks • Large quantities of CO2 • Advances the greenhouse gas count

  8. Accessible? • Electrical power is used in most homes today. • It is practically impossible to escape electricity because there is electricity in the sky.

  9. Where is it used? • Table 5. U.S. Average Monthly Bill by Sector, Census Division, and State 2007 • United States • http://www.eia.doe.gov/cneaf/electricity/esr/table5.html • Across the world there are about 2,354 power plants that produce electricity that are either hydroelectric or steam as well as nuclear. • China, USA, Russia and India

  10. CO2 • The President issued a directive on April 15, 1999, requiring an annual report summarizing the carbon dioxide (CO2) emissions produced by the generation of electricity by utilities and nonutilities in the United States • Coal is incredibly abundant but has the highest environmental impact of any fossil fuel for CO2 emissions • In the US electrical power generated (mostly from coal) is the second largest producer of toxic emission. • The most threatening material produced by coal-burning power plants consists of particles of nuclear mercury. • Analysts predict a decline in coal due to high CO2 and health risks • http://www.eia.doe.gov/cneaf/electricity/page/co2_report/co2report.html

  11. Bibliographies • Union Of Concerned Scientistshttp://www.ucsusa.org/clean_energy/coalvswind/c01.html • EIA: http://www.eia.doe.gov/cneaf/electricity/page/co2_report/co2report.html http://www.eia.doe.gov/cneaf/electricity/esr/table5.html • Plan B 3.0 • Howstuffworks.com • http://science.howstuffworks.com/electricity.htm • Miller LITE
