Presentation Transcript

  1. Lecture#1: Energy Generation Prof. Park UTI-111 Essex County College

  2. Force, Energy, and Power • Force (N) = mass (kg) x acceleration (m/s2) • Energy (Joule) = Force (N) x Distance (m) • Power (W) = Energy (Joule) / Time (s)

  3. Forms of Energy • Thermal Energy (heat) • Chemical Energy (Fuels or Batteries) • Kinetic Energy (Moving substances) • Electrical Energy • Gravitational Potential Energy • Mechanical Energy • Nuclear Energy

  4. Laws of Thermodynamics • First Law of Thermodynamics: In any transformation of energy from one form to another, the total quantity of energy remains unchanged. That is, energy is always conserved. • Second Law of Thermodynamics: When we convert energy from one form to another, the useful output is never as much as the input. That is, there is a limit to the efficiency of any heat engine.

  7. Existing Capacity by Energy Source

  8. PSEG Energy Sources • The electricity you consume comes from the Pennsylvania-New Jersey-Maryland (PJM) power grid, which receives power from a variety of power plants and transmits electricity to meet the requirements of customers throughout the region. • Your electric supplier is responsible for generating and/or purchasing electricity that is added to the power grid in an amount sufficient to satisfy electric usage requirements. • Resources used to generate electricity fall into two categories: Non-Renewable and Renewable Energy Resources.

  9. Non-Renewable Energy • Non-Renewable Energy Resources are fossil fuels (gas, oil and coal) which are burned to produce electricity, or nuclear power. • Among fossil fuels, natural gas is cleaner than coal. Coal can be burned producing fewer emissions with extensive investments in advanced pollution control equipment. • Nuclear power produces electricity without any CO2,  NOx, or SO2 emissions. PSEG produces power from gas, oil, coal and nuclear sources. PSEG has made investments in advanced pollution control equipment at its coal plants and operates state-of-the-art natural gas facilities.

  10. Non-Renewable Energy

  11. Renewable Energy • Air Emissions for CO2, NOx, and SO2 are presented as a percent of the New Jersey Benchmark. The benchmark is set at the average emissions performance of all electric generating units in New Jersey. • Approximately 50% of the electricity generated in New Jersey comes from nuclear power. Nuclear power produces electricity without CO2, NOx and SO2 emissions; therefore, New Jersey’s benchmark is low.  • Carbon Dioxide (CO2) is released when fossil fuels (coal, oil and gas) are burned. Carbon dioxide, a greenhouse gas, may contribute to global warming. Nitrogen Oxides (NOx) form when fossil fuels and biomass are burned at high temperatures. They contribute to ground-level ozone (or smog), and to the formation of acid rain. Sulfur Dioxide (SO2) is formed when fuels containing sulfur, primarily coal and oil, are burned. SO2 combines with water and oxygen in the atmosphere to form acid rain.
