The Great Energy Debate Making sense of the energy sources available in the United States
Two Types of Energy Sources • Non-Renewable/ Fossil Fuels • Coal • Natural Gas • Nuclear • Petroleum/oil • Renewable • Solar • Wind • Hydroelectric • Geothermal
Abundant and Cost efficient? • Non-Renewable • Coal is abundant and cheap • Natural Gas is abundant and cheap • Nuclear is abundant but more expensive • Petroleum is abundant at a reasonable cost • Renewable • Solar is abundant in most locations, but more expensive to harness • Wind is abundant is some locations, but more expensive to harness • Hydro electric only works in limited locations and expensive • Geothermal works in limited locations and is expensive.
Reliabilty • Non-Renewable • Power from coal is steady, can be depended on day in and day out • Power from natural is steady, can be depended on day in and day out • Power from nuclear is fairly steady, there may be maintenance and catastrophic issues involved. • Power from petroleum is steady, not used as a main source of power • Renewable • Power from solar is dependent on the sun, night time production does not happen. Less reliable • Power from wind is dependent on the wind blowing consistently. Less reliable, needs a good location. • Power from hydroelectric is affected by the water level. During low levels, production drops way down. • Power from geothermal works on a smaller scale. Not really used in large production. Reliable all the time.

So what is the problem? • Non-Renewables • Coal- dirty, pollutes the air, mining is dangerous • Natural gas- fracking can cause problems to the water supply, uses a lot of water to retrieve, flammable • Nuclear- melt downs, expensive, waste is radioactive • Petroleum- pollutes the air, spills during transport, pollutes the water. • Renewables: • Solar- production of panels and other components use dangerous chemicals, takes up land that could be used for farming, disrupts wildlife. • Wind- production disrupts landscape and wildlife, birds can hit the turbines, endangered birds and bat populations are the most concerning. • Hydroelectric- disrupts the natural flow of water, fish populations can be effected • Geothermal- drills into the earth, disrupts habitat of underground creatures.
Green Energy vs. Brown Energy • Robert Bryce – journalist, author, editor at the Energy journal, author of “Gusher of Lies: The Dangerous Delusions of "Energy Independence"” • Bias • Argument • Evidence • Tyson Slocum is director of Public Citizen's Energy Program, covering climate change, coal, oil, fracking, nuclear energy, renewables and commodity market oversight • Bias • Argument • Evidence
