RENO, NEV (April 20, 2010) - Windspire Energy, Inc. (formerly Mariah Power, Inc.), developer of the Windspire® vertical axis wind turbine, today announced it has successfully raised additional capital. The latest round of financing was led by current investors Noventi Ventures, Greenhouse Capital Partners and Big Sky Partners. These funds will be used primarily for general corporate purposes, continuing research and development efforts and underwriting the international launch of the Windspire later this year.

This announcement follows recent major announcements from the company, including a name change from Mariah Power, a new solutions-based website (www.windspireenergy.com ), and the execution of a new long-term supply agreement with a Michigan manufacturing company.
"We continue to see great potential for the Windspire," said Giacomo Marini, Chairman of the Board of Windspire Energy and Managing Director of Noventi Ventures. "There is a tremendous market opportunity, especially internationally, for this innovative small wind product. "
"From the beginning we believed that Windspire Energy would significantly expand the small wind market," said Pete Henig, Board Member of Windspire Energy and Managing Director of Greenhouse Capital Partners. "We are excited by the market acceptance of the Windspire and pleased to continue our commitment with this latest investment. "
"This new round of financing is a great vote of confidence from our current investors," said Walt Borland, President and CEO of Windspire Energy. "We will now be able to accelerate the execution of our current strategy and aggressively enter the international market later this year. "
The Windspire is a vertical axis wind turbine designed for use in urban, suburban and rural areas. The unique design of the rotor enables the turbine to generate energy silently while standing just thirty-feet tall. The thin profile of the Windspire allows customers to easily scale-up the number of turbines to meet higher energy needs.
Hundreds of Windspires are currently powering homes, businesses, schools, and museums across the United States. Recently the company announced the installation of twenty Windspires at the headquarters of leading software company Adobe Systems in San Jose, California.
