Their long-term contribution is predicated on overcoming remainingtechnical and cost barriers, mainly through intensified R&D. The National EnergyStrategy's renewable ENERGY initiatives are based on these conclusions and on a clearunderstanding of the contributions that renewable ENERGY can and cannot be expected tomake. For example, given policies to address existing regulatory barriers and marketimperfections, SOLAR thermal or photovoltaic electricity technologies can compete today toprovide electricity generation in remote locations and for peaking purposes.(National ENERGY Strategy, Executive Summary, 1991/1992)The Administration supports fundamental and applied research that helps the renewableindustry develop technologically advanced products.
