Fossil Fuels What are they? Materials that contain stored chemical potential energy and that were formed millions of year ago from plant and animal remains.

How are fossil fuels used to create electricity?

What’ the problem of using fossil fuels as our nations energy source? It’s a nonrenewable energy source!

Pollution

The primary emissions from burning coal are Sulfur dioxide – (SO2)  contributes to acid rain and respiratory illnesses Nitrogen Oxides - (Nox)  contributes to smog and respiratory illnesses. Carbon dioxide – (CO2)  primary greenhouse gas that contributes to climate change…….. Mercury and other heavy metal causes neurological damage and cancer..

What are the Impacts of Climate change? If the Earth keeps getting warmer, up to one–fourth of all the plants and animals on Earth could become extinct within 100 years. Extreme heat can cause illnesses such as heat cramps, heat stroke, and even death. Changes in weather patterns, more rain, more droughts …more extreme storms. Melting glaciers --- rising sea levels Shrinking sea ice Warmer oceans - increased in ocean acidity
