Explain in your own words how scientists have determined that a large surplus of carbon in the air is from the human activities of burning fossil fuels. Describe 5 ways that we could supply the world with energy without using fossil fuels.

Investigate Your Fossil Fuels Consumption

To aid us in our estimation, we will use the online Fossil Fuels Calculator that will convert the measurable items that we use into amounts of fossil fuel that have been consumed. This calculator is able to do this based upon some assumptions about the mix of fuel in this country. To use the calculator, you will need to find out or estimate the following quantities about your lifestyle:

• The average number of miles that you drive each year, and the mileage of your car(s).
• The number of miles that you drive/fly each year on airlines, buses, trains, taxis, and motorcycles.
• The amount of electricity that you use in your home each year.
• The amount of natural gas, propane, kerosene, or heating oil that you use in your home each year.
• The amount of gasoline that you use in your lawnmower/weed eater each year.

Plugging these numbers into the calculator will allow you to estimate how much of each fossil fuel you are responsible for consuming each year. After doing this, answer the questions on the Fossil Fuels – Capstone activity sheet ( attached below)
