1. Renewable and Non- Renewable Energy

2. Laws of Thermodynamics  First Law: In any transformation of energy from one form to another, the total quantity of energy remains unchanged.  “ Energy is neither created nor destroyed, it only changes forms. ”  Second Law: In all energy changes, the desired output energy will be less than that of the input energy – (useful energy is always lost.)  “ Lost ” energy is usually energy that has been converted to heat, but it could be noise (kinetic energy of air), or other forms of wasted energy.

3. Efficiency  The efficiency of the conversion of a fuel into electricity is always less than 100%.  This is true of all energy conversions including those not related to electricity.

4. Renewable vs Non-Renewable  Solar  Wind  Biomass  Hydro  Ocean  Geothermal  Coal  Oil  Gas  Nuclear

Every Year an Average Coal Plant Releases  3,700,000 tons of CO 2  10,000 tons of SO 2.  500 tons of particulates  10,200 tons NOx  720 tons of CO  220 tons of volatile organic compounds (VOC)  170 pounds of mercury  225 pounds of arsenic  114 pounds of lead And there are over 600 of them in the US.

14. Types of Pollutants  CO 2 – Global Warming  CO – Health problem  PM – Respiratory and heart disease, haze  SOx – Acid Rain, respiratory illness, haze  NOx – Ozone formation, acid rain, smog, nutrient loading, global warming  Mercury – Neurotoxin  Lead – Neurotoxin  Arsenic - Poison  VOCs – Numerous health problems  Ozone – Health problems, damage to flora & fauna  Hundreds of other toxic chemicals
