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 O3

What played a role in human growth in 20th 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

How Coal is Formed

• Pockets of oil and natural gas may become trapped between layers of non-porous rock

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.

Energy Use

Carbon Footprint

How to Reduce Your Carbon Footprint

Unplug! Drink from the Tap!

CFLs

Recycle

Eat local products

Renewable Energy

Wind Energy

• Fastest growing energy source in the world

How Solar Power Works

Geo-Thermal Power

How GeoThermal Works

• Ground is colder than the air in summer and warmer than the air in winter

Tidal Power

Electromagnetic Power

Hydroelectric Power

Wave Power

Sustainability

Human needs are met in such a way that a

human population can survive indefinitely
