GEOG 106 Lecture Notes - Lecture 30: Sulfur Dioxide, Energy Development, Worldwatch Institute
Document Summary
83% of energy comes from stock or non- renewable resources (coal, oil, etc. ) 17% are flow resources or those that are potentially renewable (depending on management: mostly biomass & hydropower. Most of energy debate = who, how, etc. Shares of total primary energy supply: impact of energy uses: Emission of sulphur and nitrogen oxides mixes with water to create acids in atmosphere. Two types of acid deposition: wet and dry. Wet deposition: far from source through rain, snow, etc. Dry deposition: close to source through gravitational settling. Future energy development: according to the world commission on environment and development at least four conditions need to be reconciled with respect to future energy development. > achieving these goals will be very difficult, but not impossible. Decide what is best from a variety f perspectives (economic, political, environmental, social) Difficult trade- offs will have to be made. Energy forecasts & scenarios at all scales (regional, global, and local levels)
