For the very first time, the American Solar Energy Society’s National Solar Conference will be held under the same roof with the biennial World Renewable Energy Congress. The combined event is WREF 2012. The conference will draw prominent speakers and technical presentations from universities, renewable energy laboratories, installations and industries around the world. WREF 2012 will examine how renewable energy technologies address the world’s economic, environmental and security challenges at every scale, from off-grid villages to gigawatt power plants.
