85% of US global-warming-related emissions come from our energy use; commonly, the production of excess carbon dioxide (CO2) by humans burning fossil fuels.
Transportation, home heating and electrical use are the main individual causes of this excess CO2.
The best solutions to this excess CO2 production: reduce consumption and increase efficiency when carbon fuels must be used.
People must become aware of a problem such as this before they will voluntarily take any action to solve it.
