New All-Renewables Magazine Launched in North America

TULSA, Okla., July 7 /PRNewswire/ -- PennWell Corporation announces the launch
of Renewable Energy World North America magazine. The bi-monthly b-to-b
renewables-focused magazine joins the company's well-established Renewable
Energy World Network as its latest print publication. The inaugural edition
publishes in September and will have an initial readership of 25,000
subscribers in the renewable energy industry. The new magazine offers North
American-focused news, commentary and features and complements the
industry-leading Renewable Energy World magazine, also a PennWell publication
based out of London.

Renewable Energy World North America magazine will be the flagship media
sponsor for Renewable Energy World Conference and Expo North America. Its Web
site will be RenewableEnergyWorld.com. Both the conference and the Web site
are already major information and networking forces within the renewable
energy community. PennWell's Renewable Energy World Network is rounded out by
Renewable Energy World Conference and Expo Europe. With a new U.S.
Administration supporting massive government investments and incentives in
carbon-neutral renewable energy and infrastructure and with continuing strong
support across Canada, the North American marketplace will be advancing into
an era of solid growth in green technologies. "There is an undeniable momentum
shift at all levels of government and large businesses to address climate
change, and a broad recognition of the strong role of renewable energy in
reducing greenhouse gas emissions," says Dick Rauner, Group Publisher of
Renewable Energy World North America magazine.

Renewable Energy World North America magazine will cover utility-scale
renewable power generation, including wind, solar, biomass, geothermal and
hydroelectric sources. The magazine will also cover the world of finance,
critical to the success of renewable energy project developers, technology
companies and innovators. And it will offer interviews, profiles, industry
news and insightful data all presented in a visually exciting design.

The magazine's editorial team will be led by David Wagman, who spent four
years at the National Renewable Energy Laboratory, has been Chief Editor of
Power Engineering magazine since 2006 and is co-chairman of Renewable Energy
World Conference and Expo North America. Joining David are Jennifer Runyon,
Managing Editor, Graham Jesmer, News Editor, and Stephen Lacey, Podcast
Producer and Editor from RenewableEnergyWorld.com; Peter Singer, Editor in
Chief of Photovoltaics World magazine; and Nancy Spring, Senior Editor of
Power Engineering magazine.

"This group of editors is as solid as it gets," said Wagman. "Their industry
knowledge is second to none. Couple that with our stable of columnists and
industry-expert authors, and Renewable Energy World North America magazine
sets a new standard of excellence."
