Non-renewable and Renewable Resources How to not use up what we got to create the energy we need
7.02 billion People on Earth Smog contains ground level ozone from burning fossil fuels; ground level ozone forms when an oxygen molecule is transferred from nitrogen dioxide to an oxygen molecule creating O 3
What played a role in human growth in 20 th century? Improved transportation which increased immigration ---when people from developing countries immigrate to developed countries they obtain better nutrition, better medical care which results in longer life and more births.
Greenhouse Gases and Earth We need greenhouse gases to absorb infrared radiation to keep the Earth warm. BUT We have created a trend of increasing temperatures on Earth due to our increase use of fossil fuels.
We have modified our environment due to technological advances
World population Can stabilize after fertility rates fall below replacement level
Resource most impacted water
Diseases Dysentery—spread through unsafe water sources TB—spread through close contact then international travel Malaria—spread through global warming providing increases in disease carrying mosquitoes
What We Use
Five Factors that influence value of fuel Cost Availability Safety Energy Content Byproducts of the fuel’s use
Resources vs Reserves Resources natural concentrations of minerals or, bodies of rock that are, or may become, of potential economic interest due to their inherent properties. Reserves the estimated quantity of minerals that could be extracted from a site, is of considerable importance to governments, international agencies, economists and the international energy industry.
Resources vs Reserves
Fossil Fuels Are readily available and inexpensive compared to alternative energy sources

Non-renewable Energy Sources
Natural Gas Natural gas is usually found underground near an oil source. It is a mixture of light hydrocarbons including methane, ethane, propane, butane, and pentane. Natural gas is the cleanest burning fossil fuel.
