These sources have minimal bias and use very few loaded words (wording that attempts to influence an audience by using appeal to emotion or stereotypes).  The reporting is factual and usually sourced.  These are the most credible media sources. See all Least Biased Sources.

Factual Reporting: HIGH

Notes: The IEA works to ensure reliable, affordable and clean energy for its 29 member countries and beyond. Their mission is guided by four main areas of focus: energy security, economic development, environmental awareness and engagement worldwide. IEA produces scientific studies that could easily place this source in our Pro-Science category. They also report energy based news that is well sourced and factual. The IEA has a slight left political bias in affiliation as it relates to concern for human caused climate change. Despite this, all information is presented in neutral wording and is grounded in evidence, therefore we consider the IEA least biased. (D. Van Zandt 3/23/2017)
