Last year, U.S. energy-related carbon emissions were at the lowest levels since 1994, emitting “only” 5.3 billion metric tons of carbon.
This is largely from declining coal use due to cheap natural gas, lower demand for transportation fuels and a mild winter, says the U.S. Energy Information Agency.
Although we don’t like to think that solar energy contributes to emissions, it does, and there’s good news there, too.
To get the solar industry where it is today required huge inputs of electricity. Ironically, most of that comes from coal-fired power plants.
For example, to produce polysilicon — the basic building block of most solar panels — silica rock must be melted at 2,000 degrees Fahrenheit using electricity, commonly from coal-fired power plants.
