Renewable Energy Learning Path

Definition of renewable energy

Renewable energy is energy harnessed from natural processes that are replenished faster than they are consumed. The International Energy Agency describes it as energy derived from natural processes that renew themselves on a faster timescale than human use. Commonly recognized renewable sources include solar power, wind power, hydropower, geothermal energy, and biomass. Renewable energy is often used to replace conventional fuels across several sectors, including electricity generation, hot water/space heating, transportation, and off-grid (rural) energy services. While renewables generally produce far fewer carbon emissions than fossil fuels, “renewable” is not the same as “low-carbon,” because some renewables can still be carbon-intensive depending on how they are produced (for example, certain biomass pathways). Renewable energy is also distinct from “sustainable energy,” which is a broader concept focused on long-term impacts on future generations.
