Document Summary
Disproportionate amount of energy resources demanded and consumed in developed countries (small proportion of populations) Growing challenges: how to break energy dependency get sustain development and high standard of living. Energy shock: constant worries from past to present and to the future over the price, dependency, power failures. [rome: wood] [1970, oil peak cost] [1998, st lawrence electricity, great ice storm, local energy shock. ] [2003, power blackout easter us and on, failure of local power transmission due to inter-dependent power grid] Fossil fuels (non-renewable resource): 90% of us energy consumption (10% from hydropower and nuclear power) Conventional fossil fuel peak discoveries in 1960. Energy consumption increasing over time due to population increase. Bridging fuel: used to bridge from fossil fuel to renewable energy. Transformed from the solar energy originally stored in organic matter. Organic matter buried and preserved as fossil fuels. Environment impact: significant impact from exploration, production, processing, and distribution.
