Energy consumption, including transport, is currently the main source of emissions of greenhouse gases and acidifying pollutants. According to the European Environment Agency (EEA), the emission of these last pollutants has been reduced significantly thanks to the adoption of cleaner fuels and the treatment of combustion gases. But while the role of fossil fuels in the energy basket does not diminish, the greenhouse gases that cause climate change seem to be bound to increase. Greater energy efficiency and an increase in the use of renewable energies are seen as part of the solution.
In the following graph we can see the world-wide production of electrical energy, broken down according to its origin. Carbon is the main source of energy, and hydraulic is the most abundant in renewable energy.
WORLD PRODUCTION OF ELECTRIC ENERGY
Also at the national level, renewable energies represent an important percentage in the generation of electric power. Within renewable energies, hydraulics, as we have said, is the main one; such and how we can appreciate in the following tables.

If we speak already in terms of consumption, then we can compare what is the primary energy consumption in Spain and the renewable energy, which has gone from 5983 Ktep in 1990 to the more than 20,000 ktep that are foreseen for the 2010

Nowadays, renewable energies, apart from respecting the environment, constitute an important source of job creation. According to the forecasts, the energy that will report the most jobs is the energy coming from the biomass.
