However over the previous 500 years approximately, humans significantly relied on less expensive, dirtier energy sources such as coal and fracked gas. Now that we have increasingly ingenious and less-expensive ways to catch and maintain wind and solar power, renewables are ending up being a more essential power source, representing more than one-eighth of U.S.

The expansion in renewables is also happening at scales big and little, from roof solar panels on houses that can offer power back to the grid to huge overseas wind farms. Even some entire rural communities rely on renewable resource for heating and lighting. As sustainable use continues to grow, a key goal will be to improve America's electrical energy grid, making it smarter, more safe, and much better integrated across areas.

Distributed solar systems generate electrical power in your area for houses and businesses, either through roof panels or community projects that power whole areas. Solar farms can produce power for thousands of houses, utilizing mirrors to focus sunlight throughout acres of solar batteries. Drifting solar farmsor "floatovoltaics" can be an efficient usage of wastewater facilities and bodies of water that aren't ecologically delicate.
