A feed-in tariff (FIT, standard offer contractadvanced renewable tariff or renewable energy payments) is a policy mechanism designed to accelerate investment in renewable energy technologies. It achieves this by offering long-term contracts to renewable energy producers, typically based on the cost of generation of each technology. Technologies such as wind power, for instance, are awarded a lower per-kWh price, while technologies such as solar PV and tidal power are offered a higher price, reflecting higher costs.

In addition, feed-in tariffs often include "tariff degression", a mechanism according to which the price (or tariff) ratchets down over time. This is done in order to track and encourage technological cost reductions. The goal of feed-in tariffs is to offer cost-based compensation to renewable energy producers, providing the price certainty and long-term contracts that help finance renewable energy investments.

FITs typically include three key provisions:

Under a feed-in tariff, eligible renewable electricity generators (which can include homeowners, business owners, farmers, as well as private investors) are paid a cost-based price for the renewable electricity they produce. This enables a diversity of technologies (wind, solar, biogas, etc.) to be developed, providing investors a reasonable return on their investments. This principle was first explained in Germany's 2000 RES Act:

Ralph Nader ( /ˈneɪdər/; born February 27, 1934) is an American political activist, as well as an author, lecturer, and attorney. Areas of particular concern to Nader include consumer protection, humanitarianism, environmentalism, and democratic government.

Nader came to prominence in 1965 with the publication of his book Unsafe at Any Speed, a critique of the safety record of American automobile manufacturers in general, and most famously the Chevrolet Corvair. In 1999, an NYU panel of journalists ranked Unsafe at Any Speed 38th among the top 100 pieces of journalism of the 20th century.

Nader is a six-time candidate for President of the United States, having run as a write-in candidate in the 1992 New Hampshire Democratic primary, as the Green Party nominee in 1996 and 2000, and as an independent candidate in 2004 and 2008. Some people claim that Nader acted as a spoiler in the 2000 U.S. presidential election, while others, including Nader, dispute this claim.

Nader was born in Winsted, Connecticut. His parents, Nathra and Rose (née Bouziane) Nader, were immigrants from Lebanon and members of the Maronite Church. His family's native language is Arabic, and he has spoken it along with English since childhood. His sister, Laura Nader, is an anthropologist. His father worked in a textile mill and later owned a bakery and restaurant where he talked politics with his customers.
