Understanding green energy
“Green energy” is often used interchangeably with “renewable energy,” but the two terms are technically different. Green energy is the subset of renewable resources that has the least environmental impact. According to the Environmental Protection Agency (EPA), green power sources include “solar, wind, geothermal, biogas, eligible biomass, and low-impact small hydroelectric sources.”
Renewable energy refers to resources that naturally replenish themselves over time. However, not all renewable energy sources are considered green because some may have an impact on the environment. For example, large hydroelectric power is renewable, but it can negatively impact fish populations and their ecosystems.
