[6] A previous target of 20% for 2020,[7] with an additional 0.8% available for other EU countries under the cooperation mechanism, was reached and slightly surpassed.

[11][12] In 2023, the share of electricity generated from renewable sources rose to 50.8%, reflecting the country's progress towards its decarbonisation goals.

This is comparable to the International Energy Agency (IEA) median for 2019, which stood at 38% of electricity generation from renewables.

[5] In the early 2000s, the growth of wind power contributed to an increase in Spain's renewable electricity production.

The installation of photovoltaic (PV) plants beginning in 2007 played a key role in this increase, doubling the renewables' share in Spain's electricity mix from 20% in 2008 to 40% in 2013.

[5] Spain's renewable energy sector has undergone significant shifts, initially driven by the 1997 Special Regime and Royal Decree 661/2007, which promoted considerable growth in wind and solar PV installations through favorable conditions and feed-in tariffs.

However, the dynamics of the sector shifted following legislative reforms in 2012, marked by the enactment of Law 24/2013 and Royal Decree 413/2014.

These reforms introduced a new financial framework for the electricity market, modifying compensation mechanisms for renewable sources, which led to a deceleration in new developments.

Environmentalists have criticised the tax for artificially blocking Spain from continuing its long standing movement to renewable energy production.

In the same year in terms of wind energy production Spain was much stronger in 3rd position (495 kW per 1000 inhabitants).

Iberdrola plans to build 19 solar photovoltaic power plants and three onshore wind farms in Spain, Portugal, and Germany, with a total capacity of nearly 2.2 gigawatts.

These projects aim to generate 4 terawatt-hours of electricity, equal to the annual consumption of over 1 million households.

Importantly, 70% of these installations will be in rural areas affected by the transition to net-zero emissions, fostering regional development.

To ensure a stable power supply, Iberdrola will integrate hybrid battery systems into its photovoltaic projects.

These plants are expected to be operational by the end of 2028, aligning with the European Commission's REPowerEU plan to reduce fossil fuel imports and accelerate the green transition.

According to projections by the updated Spanish submission dated 20/12/11 by 2020 the gross final energy consumption in Spain by sector breaks down as follows.

By using more efficient thermal generation the potential remains to reduce energy wastage by almost a third and to cut CO2 emissions accordingly.

The current generational mix of electricity production can be checked in real time on the Red Electrica de Espana website.

In 2014 biomass provided the largest share of RE in the heating and cooling sector at approximately 13.65% of the total, equating to 3.862 million tonnes of oil equivalent.

In that year, the year-end installed capacity was 23 GW and the annual production was 51,439 GWh, a share of total electricity consumption of 21.1%.

A rough calculation shows that the contribution to total net generation varied approximately between 9-17 percent annually.
