What is clean energy?

NCSEA defines clean energy as energy derived from renewable, zero-emissions sources (“renewables”), as well as energy saved through energy efficiency (“EE”) measures.


How do renewables and energy efficiency work together?

Renewable energy is derived from natural processes that are regenerative over short periods of time and cannot be depleted. The most common renewable energy resources are biomass, geothermal, hydropower, solar, and wind.

Energy efficiency manages and restrains the growth in energy consumption. Something is more energy efficient if it delivers more services for the same energy input, or the same services for less energy input. (Source: IEA)

Put simply: A clean energy economy powered by both renewables and energy efficiency is the most sustainable energy planning scenario available.
