Understanding green energy
“Green energy” is often used interchangeably with “renewable energy,” but the two terms are technically different. Green energy is a subset of renewable resources with 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, as some still have negative environmental impacts. For example, large hydroelectric power is renewable, but it can negatively impact fish populations and their ecosystems.
