Renewable Energy: The Clean Facts
Wind and solar are powering a clean energy revolution. Here’s what you need to know about renewables and how you can help make an impact at home.
What is renewable energy?
Renewable energy, often referred to as clean energy, comes from natural sources or processes that are constantly replenished.
Sunlight and wind keep shining and blowing, even if their availability depends on time and weather.
Renewables are increasingly displacing ‘dirty’ fossil fuels in the power sector, offering lower emissions and a cleaner environment.
As renewable use grows, modernizing the electricity grid to be smarter and more secure is a key goal.
More than 12% of U.S. energy generation now comes from renewables, and the expansion continues at various scales.
Types of renewable energy sources
Solar energy: Uses photovoltaic cells to convert sunlight into electricity, with distributed solar systems powering homes and businesses.
Wind energy: Uses turbines to convert wind power into electricity, accounting for 9.2% of U.S. electricity generation.
Hydroelectric power: Converts moving water into electricity, but large dams can have environmental impacts.
Biomass energy: Comes from organic material but can emit carbon and affect biodiversity if not sourced sustainably.
Geothermal and ocean energy: Harnessing Earth’s internal heat and oceanic forces to generate power is still developing.
Renewable energy in the home
Solar power: Rooftop panels or passive solar home designs help generate and store energy efficiently.
Geothermal heat pumps: Use Earth’s stable temperature to heat and cool homes efficiently.
Small wind systems: Homeowners in high-wind areas can install turbines to generate their own electricity.
Selling energy: Homeowners generating excess renewable energy can sell it back to the grid through net metering.
Even without installing renewables, individuals can opt for clean energy sources from their utility providers.
