Learn about clean energy, the impact of energy on the environment, and U.S. electricity generation. Clean energy includes renewable energy, energy efficiency and combined heat and power.
Understanding the difference between clean and renewable energy is pivotal for shaping a sustainable future. While renewables offer an inexhaustible supply, clean energy criteria ensure
One final point of confusion is the difference between clean and renewable energy. “Renewable energy” simply means energy that comes from an effectively infinite source, like wind or
UNEP engages directly with the public and private sector to develop sustainable markets for renewable energy. This is accomplished through individual projects and programmes, as well as
By transitioning away from fossil fuels — like coal, oil, and gas — and embracing scalable clean energy solutions — like solar, wind and more — we can reduce pollution, create jobs, and
Yet even with this significant growth in renewable and other zero-emission capacity, the world is still burning, and increasing its use of, fossil fuels. Geopolitical turmoil and volatile markets
Clean energy refers to energy sources that produce little to no pollution and greenhouse gas emissions. It primarily includes renewable energy derived from natural processes that are
Renewable energy sources — such as sunlight, wind, water, organic waste, and heat from the Earth — are abundant, replenished by nature, and emit little to no greenhouse gases or air pollutants.
Our vision is for a clean, green and equitable energy future. A rapid and responsible transition to renewable energy will bring a wide range of benefits: jobs and economic development,
