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