If an electric utility generates power from renewable resources and sells renewable energy certificates representing the renewable attributes of that energy, can it still call the underlying power "renewable"? No, according to the U.S. Federal Trade Commission.

While this question may seem metaphysical, it arises from the structure of most U.S. renewable energy markets.
Most states have adopted renewable portfolio standards, which require utilities and competitive electricity suppliers to source some of their power from renewable resources. In most cases, utilities and suppliers can satisfy this requirement by using renewable energy certificates or credits known as RECs. While each state's program differs, these RECs typically represent the renewable attributes of electric energy -- the right to claim that energy is renewable -- but are distinct from that underlying energy. As a result, a renewable generator can sell RECs to one buyer and the underlying energy to another.
Vermont utility
Green Mountain Power Corporation recently found itself at the center of controversy over its claims regarding renewable energy. The utility owns and is involved with a variety of renewable energy generation projects in Vermont, including
wind and
solar projects. It sells energy produced from these projects to Vermont customers, while simultaneously selling some of the RECs generated by these sources
to
out of
state utilities.
In 2014, concerns over "double counting" of renewable energy attributes led Connecticut to ban the use of RECs from
renewable generation that also
is
counted toward another state’s
renewable
goals for meeting Connecticut's requirements, and
REC marketer NextEra Energy to notify New England market participants that it would no longer buy Vermont RECs.
On September 15, 2014, a group of
petitioners asked the Federal Trade Commission to investigate Vermont utility Green Mountain Power Corporation's claims that
it is providing its customers with electricity
from renewable sources such as
commercial
wind
and solar projects, given its separate sale of the RECs to out of state utilities. The Federal Trade Commission regulates claims about the environmental
impacts of commerce under Section 5 of the Federal Trade Commission Act,
including
claims regarding the production, sale, and use of renewable energy. In their complaint, the petitioners claimed that "Vermont customers are
being misled into thinking that they are
buying 'renewable
energy,'
when in fact what they are getting is 'null'
electricity
consisting of a
mix
of
fossil fuel,
nuclear, gas
and other 'brown'
sources
of electricity
from the regional grid."
The FTC responded to this petition in February 2015 by
issuing a letter to Green Mountain Power's counsel expressing concern that the utility might have created confusion for its customers about the renewable attributes of the power they purchased by not “clearly and consistently communicating” that it sells RECs for most of its renewable energy-generating facilities to entities outside Vermont.
In the letter, the FTC said that it had not found that any Green Mountain Power statements violated the Federal Trade Commission Act. However, the Commission urged Green Mountain Power in
the
future
to
prevent
any
confusion
by
clearly
communicating
the
implications
of
its
REC
sales
for
Vermont
customers
and
REC
purchasers.
The FTC letter represents the latest salvo in efforts to regulate claims regarding the production, sale, and use of renewable energy. To help marketers avoid making deceptive environmental claims, for over 20 years the
FTC has issued "Green Guides" providing its administrative interpretation of the law. The Green Guides outline general principles that apply
to all environmental marketing
claims and provide
guidance
regarding
many
specific
environmental benefit claims, including renewable energy claims. The Green Guides, as well as the recent FTC letter, illustrate the importance of caution in making claims about renewable energy in business activities.
