Strategies for Energy Conservation and Sustainable Practices in the U.S.

DESCRIPTION

This analysis explores the current energy consumption trends in the U.S., highlighting the increasing per capita usage of electricity and petroleum. It reveals that only 44% of total energy is deemed useful, and outlines the potential energy savings from proposed mileage regulations. The discussion includes calculations on saved petroleum, associated cost benefits, and practical energy-saving tips for households. Understanding energy reserves and consumption timelines is essential for shaping policies that promote sustainability and conservation.

  1. Energy Conservation

  2. Hydroelectric 1.0 Geothermal 0.0013 Rejected Energy 35.7 Nuclear 3.0 Natural Gas 16.4 Useful Energy 31.5 Coal 18.3 Petroleum Oil 20.0 Imported Oil 15.5 Export total is 2.1

  3. Only 44% percent of “All” energy is useful.

  4. Only 33% of “All” energy is used.

  5. Only 44% of “All” energy was used

  6. Only 44% off “All” energy will be used.

  7.

  8. In Kwh • In 1976 the population was 218,035,164 and in only 35 years the population is 307,006,550. • The average U.S. citizen in 1976 consumed roughly 8,500Kwh. • The current average U.S. citizen consumes roughly 12,000Kwh. • 218,035,164 x 8,500kwh = 1.8E12kwh in 1976 • 307,006,550 x 12,000kwh = 3.7E12kwh in 2011 • Per capita U.S. double the consumption of energy in only 35 years.

  9. Questions…. • How much petroleum would the U.S. save if the U.S. sets a mileage regulation of 10,000miles a year?

  10. Things to Know. • Driving population between the ages of 16-70. • Population between 16-70 is 197,500,00. • Average miles driven: 13,500. • 42 gallons in a barrel. • Average mpg for a U.S. car is 20. • Price of a barrel is $107. • Average petroleum consumption = 18,771,000 barrels/day

  11. Equations…. • 13,500miles-10,000=3500miles saved • 3,500miles x 197,500,000= 691,250,000,000miles could be saved • 6.9125E11miles/20mpg=3.4563E10gallons could be saved • 3.4563E10gallons/42gl/barrel= 823,095,238barrels could be saved • 823,095,238barrels x 5.8E6Btu = 4.774Qbtus could be saved

  12. More Equations… • Percent of energy saved for U.S. petroleum: 4.774QBtu/35.75QBtu = 13.4% • How many days worth of oil would be saved a year: 823,095,238barrels / 18,771,000 barrels/day = 43days • Money saved by U.S. regulation: 823,095,238barrels x $107per barrel = $88,071,000,000 a year.

  13. Assumptions • Everyone between the ages of 16-70 drives 13500miles. • Oil barrel price averages at $107(current oil price).

  14. Idea's for cutting down the use of energy: • Fixing leaks in your house • Changing light bulbs to compact fluorescent "squiggly bulb" • Close window drapes at night to prevent heat from exiting out the windows. • Plug cell phone, computer, game council chargers into a power strip and turn strip off when not in use.
