The Global Local Process By Rory, Julie, Jerry, Rudy
Objectives of this Presentation • Show the current trend in population and energy growth. • Show the connection between the two. • From there, extrapolate this connection into the Global context.
Three points of Population Trends • Rural to urban migration from 1900-1950 • Urban to suburban migration from 1950-2000 • Similarities around the world
Twin Cities Metro Area • Metro Area consists of seven major counties: Anoka, Hennepin, Carver, Scott, Dakota, Ramsey and Washington.
Overview of Population Change of Minnesota and the Twin Cities Metro Area From 1900-2000 • Population of both the Twin Cities and Minnesota grew dramatically • World population grew 4 times larger
Population Trends 1960-2000 • Population movement from Urban to Suburban • Less people in more houses • Urban Sprawling
1950-2000 • 64% live in Urban Areas in 1950 • 79% live in Urban Areas in 2000 • Urban land population increased 87% • Urban population density decreased 54% • Urban land area increased 400% • Average number of people per houshold decreased from 3.47 to 2.68 • Number of household increased 142%
Decrease in Population density in Metro Centers around the world • 30% Western Europe • 32% Australia • 33% Canada • 18% Japan Example Paris, New York and Tokyo have all lost 60% of their population since 1900
Minnesota Residential Energy Consumption Estimates in 1960 • Coal – 557 thousand short tons • Natural Gas – 61 billion cubic feet • Petroleum – 10,270 thousand barrels • Wood – 878 thousand cords • Electricity – 4,186 million kilowatt-hours Sources: Energy Information Administrative
Minnesota Residential Energy Consumption Estimates in 1970 • Coal – 320 thousand short tons • Natural Gas – 102 billion cubic feet • Petroleum – 14,782 thousand barrels • Wood – 560 thousand cords • Electricity – 9,031 million kilowatt-hours Sources: Energy Information Administrative
Minnesota Residential Energy Consumption Estimates in 1980 • Coal – 30 thousand short tons • Natural Gas – 103 billion cubic feet • Petroleum – 8,989 thousand barrels • Wood – 893 thousand cords • Electricity – 11,749 million kilowatt-hours Sources: Energy Information Administrative
Minnesota Residential Energy Consumption Estimates in 1990 • Coal – 22 thousand short tons • Natural Gas – 107 billion cubic feet • Petroleum – 6,185 thousand barrels • Wood – 562 thousand cords • Electricity – 14,858 million kilowatt-hours Sources: Energy Information Administrative
Minnesota Residential Energy Consumption Estimates in 2000 • Coal – 1 thousand short tons • Natural Gas – 129 billion cubic feet • Petroleum – 7,730 thousand barrels • Wood – 409 thousand cords • Electricity – 18,629 million kilowatt-hours Sources: Energy Information Administrative

Energy Consumption A discussion of Minnesota's rapid population growth is strangely absent in all state energy reports, even those projecting energy use!
State’s Energy Proposals • Conservation of existing energy sources • Construction of additional sources of energy, natural gas peaking plants, and renewable and alternative energies, primarily wind power; and • Increasing prices to ration consumer use
Minnesota’s Future Energy Demands • In 1998 Minnesota produced a total of 1,419 trillion BTUs of energy and consumed a total of 1,261.3 trillion BTUs • The difference between production and consumption are due to infrastructure losses
Minnesota Energy Inputs by Source • Wind/Solar/Other 3 0.21%Total 1261 100.0% • Trillion BTUs. *Includes wood and burning of wastes. Data from Minnesota Energy Planning Report
Minnesota Energy use by Economic Area Economic Area Btu’s Percent Commercial 137 10.9% Residential 212 16.8% Industrial 450 35.6% Transportation 462 36.7% Total 1261 100.0% Trillion BTUs EIA data. See at < http://www.eia.doe.gov/emeu/recs/tables/enduse_consump.html
Projected Construction Costs and New Generation Under the Status Quo Growth Scenario (000,000) • Under the current growth scenario, between $250 and $500 million, or more, of power generation construction is required every year for the foreseeable future
