They are free sources of energy
Solar and wind energy sources are the most popular sources.
They come from sources that are practically limitless.
Both solar and wind produce most of our energy today.
5
How do fossil fuels relate to global transportation problems?
We're all out of fossil fuels, so transportation system fail
There's no connection between fossil fuels & transportation
Fossil fuels help solve these transportation problems
Increasing transportation means we consume more fossil fuels
6

wood
uranium
coal
gasoline

gold, trees, grass, water, sunlight
water, sunlight, gold, grass, trees
trees, grass, gold, sunlight, water
sunlight, water, grass, trees, gold
10
Scientists believe Earth's average temperature is increasing at an accelerated rate because
rising sea levels cause more solar energy to be absorbed
increase in volcanic activity is making more dust in the air
the Earth's axis is tilting more in the direction of the Sun
burning fossil fuels is increasing the carbon dioxide level
