Solar Roads – a very big idea with a very big promise.
About 40% of U.S. carbon dioxide emissions stem from the burning of fossil fuels for the purpose of electricity generation.
Coal accounts for 93% of the emissions from the electric utility industry (US Emissions Inventory 2004).
It is estimated that approximately half (different agencies provide different estimates, but the average is about 50%) of the greenhouse gases that are causing global warming come from the burning of fossil fuels (primarily coal) to generate electricity. The Solar Roadway promise it that they could, therefore, eliminate half of the greenhouse gases currently being produced, and a prototype is apparently being developed.
