The contribution from nuclear power to Spain's energy portfolio increased until about 1988 and remained near constant from there on, but after that its market share declined as demand rose and use of traditional fossil fuels skyrocketed thermofossil hydroelectric nuclear Other renewables
The second generation of plants were domestically built by companies including Empresarios Agrupados, INITEC and ENSA. Five of these were built.
The third generation includes the Trillo-1 and Vandellos-2. All of the other 5 units of this series were halted in the middle of construction after a moratorium stopping further construction passed in 1994. Capacity of the nuclear fleet has still increased since then due to power uprates.
ENUSA is a company in Spain with various holdings in Uranium mining. A Uranium mine in Saelices el Chico was operated for some time, but is now decommissioned and Spain imports all of its Uranium fuel.
Funding for waste management is paid by a tax of 1% on all revenues from nuclear power, which is slightly less than for the United States, which is 1/10th of a cent per kWh (assuming costs are less than 10 cents per kWh it is less than 1%).

Spain is one of the three world’s largest users of wind power with an installed capacity of 15,515 MW at January 2008.1 In 2007, wind farms accounted for almost 10% of the electricity generated in Spain.2 On particular windy days, wind power generation has surpassed all other electricity sources in Spain, including nuclear3.
