Global environmental concerns and the escalating demand for energy, coupled with steady progress in renewable energy technologies, are opening up new opportunities for the utilization of renewable energy resources. This chapter discusses a novel uninterruptible and environment-friendly wind-solar hybrid energy system with suitable cooling and reflector systems. It examines the effectiveness of three different structures/materials as reflectors: silvered glass plane mirror, convex spherical mirror and aluminum foil. The use of solar photovoltaic electric systems is growing rapidly in the sustainable renewable energy market, and these are expected to play an important role in the mix of future sustainable energy. A passive-air-cooled system for solar panels involves the installation of heat sinks at the rear side of the solar panel. A heat sink transfers thermal energy from the higher-temperature rear side of a solar panel to the lower-temperature surrounding air.
