  • 24 October 2014: Renewable Energy Contractors Benefit from PACE Financing
    One third of all energy is wasted. Is PACE the solution? According to current energy data, commercial and industrial buildings use about 60 percent of the energy generated in the U.S. and about a third of this energy, especially in older buildings, is wasted due to inefficiency. But how do we know which third, and what can we do about it? The answe> <>
  • 24 October 2014: Designing Reliable, Cost-effective Wind Turbine Shaft Systems
    A wind turbine’s main shaft requires a reliable bearing for operation. Some bearing designs have been known to fail prematurely resulting in costly maintenance repairs. Recent upgrades and advances in bearing designs increase reliability, and ensure main shaft stability. Selecting the proper bearing is beneficial to a wind turbine’s overall performance.> <>
