What is Clean Energy?

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 includes technologies (including passive solar), products, and services that reduce the amount of energy required for buildings, processes, or tasks. Find out more.

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