Reseach Topic Proposal and Outline: Hydroelectric Dams

I will be doing my research topic on hydroelectric dams. I will be focusing on the negative aspects of hydroelectric dams. The negative aspects include the release of methane, carbon dioxide and other greenhouse gases, and destruction of forested lands by the dam reservoir, The volume of greenhouse gases released by dams can in some instances make them less efficient and environmentally friendly than fossil fuel burning facilities. I want to show that hydroelectric electricity is not always the best method of production and in some cases is the worst option.

Thesis: Although hydroelectric dams are believed to provide a relatively clean source of electricity, they cause an increase in greenhouse gases because flooding destroys carbon dioxide filtering vegetation and forests, decomposing organic material releases methane and stored carbon dioxide into the water, and the dam’s turbines release these gasses into the atmosphere.

I. Flooding/Construction of Reservoir

A. Reservoir covers massive acreage and huge volumes of organic matter

1. Cause of Reservoir

B. Three Gorges Dam

C. Bella Monte Dam

D. Other effects of the Reservoir

II. Decomposition of Organic Material in Reservoir

A. Discussion Point

1. Aerobic breakdown generate carbon dioxide

2. Anaerobic breakdown generates methane gas

III. Release of Methane Gas/Carbon Dioxide into Atmosphere

A. Methane Gas

1. Methods of Release

2. Effects

B. Carbon Dioxide

1. Methods of Release

2. Effects

C. Volume of Greenhouse Gases Released

1. Tropical and Temperate Dams

D, Summary
