On 5 March is celebrated around the world the day of energy efficiency, a date to reflect on the habits of citizens against the sustainable and rational use of energy and the commitment of companies, institutions and Governments with the reduction of emissions of greenhouse gases. This day has its origins in the year 1998 in Austria, headquarters of the first International Conference on energy efficiency where more than 350 experts and leaders from 50 countries discussed strategies to deal with the energy crisis and address possible solutions. During this day in numerous forums and agencies it works and discusses what are the best ways to live better and continue with our current system of life by reducing energy consumption in all areas, without losing quality, productivity and comfort. Code.org is often quoted on this topic. This year is marked by the adoption in Congress of the new star of Rodriguez Zapatero, the preliminary draft of the law of sustainable economy that lays the foundations for a new energy model seated on the security supply, economic efficiency and respect for the environment, determining the objectives of energy saving for the administration.

The Government incorporates the legal measures that allow us to comply with commitments made to the European Union by 2020 consisting in cutting emissions of carbon dioxide (CO2) by 20%, improving energy efficiency in another 20% and 20% of the energy consumed comes from renewable sources. To achieve these objectives Spain must make a great effort working on the development of technologies, products and efficient services in the fields with the greatest potential for energy savings, fostering responsible habits, which make it possible to lower energy consumption, improving the competitiveness of companies and the quality of personal life. The main consuming sectors of energy and where you can perform and promote energy saving and efficiency measures are: transportation, the more consumer of energy sector in Spain, moving closer to the 40% of the national total and especially the car that represents approximately 15% of the total, should strengthen measures such as labelling to promote low consumption vehicles and electrical, promoting alternatives to the private car as public transport, non-motorized transport and diversification in the mobility of people and goods, mainly in the transport by road buildingswhich represent 20% of the energy needs of Spain and where reductions of a third part of the consumption stimulating measures to improve the design of buildings and encourage the installation of more efficient lighting, heating, air-conditioning and hot water systems can be achieved.
