A company in Idaho is developing an alternative to the antiquated roads that are currently used. They're built of solar panels that can store power, melt snow, transmit data and power, and illuminate.
From the site:
The Solar Roadway™ is a series of structurally-engineered solar panels that are driven upon. The idea is to replace all current petroleum-based asphalt roads, parking lots, and driveways with Solar Road Panels™ that collect and store solar energy to be used by our homes and businesses. This renewable energy replaces the need for the current fossil fuels used for the generation of electricity. This, in turn, cuts greenhouse gases literally in half
