A QUARTER A KILOWATT HOUR: GETTING SERIOUS ABOUT BUILDING A SOLAR ENERGY FUTURE

摘要

Solar energy is widely accepted as central to a sustainable energy future. Today's photovoltaic cells cleanly and efficiently convert the Sun's energy into useful electrical energy. Although the solar photovoltaic industry has experienced robust annual growth rates over the past two decades, solar still supplies less than 1 % of primary energy globally, A specific proposal for a 250/kWh fixed purchase price for all electricity generated using grid-tied solar photovoltaic systems in the U.S. is proposed. This approach, often referred to as a solar or renewable energy feed-in law/tariff, has yielded success in other countries. For example, Germany has experienced rapid growth in photovoltaic installations in recent years spurred by a very favorable solar feed-in tariff. The scope of the energy-environment challenge calls for an aggressive policy such as this to accelerate the deployment of clean, renewable forms of energy.
