Global Solar Energy Trends and Potential of Building Sector In Hungary

As the present trends show current policies lay more stress on using solar energy and renewable energy sources as some years before. There is a 175 000 TW power of solar energy, which came from the Sun. If it could be exploited, less than 10 % of this would be enough to cover the human economy. The solar energy has an important role in the reduction of the Ecological Footprint of humanity. This research would be offered a survey the global solar energy trends and the potential of building sector in Hungary. Furthermore, also the alternative energy sources appeared in the transport: many governments give financial assistance to the proliferation of electric cars. Government and policy support for renewable energy has increased considerably over the past decade. Two drivers underpin this trend: first, the effort to constrain growth in greenhouse-gas emissions and, second, concerns to diversify the supply mix (promoted particularly by high oil prices, especially in 2005-2008). To address these concerns, more and more governments are adopting targets and taking measures to enhance the share of renewables in the energy mix
