Table 4 provides a look at previous registrations or allocations to
assess the future of each community's renewable energy generation.
Wind energy dominates this table. Castilla–Leon (4953 MW), Murcia
(4751 MW), and Castilla–La Mancha (3464 MW) have the most
allocated facilities, but Extremadura, which has been one of the
leaders in solar and has no installed wind energy, occupies fourth
place with 1327 MW, of which 1227 MW are from wind (Fig. 19).
New solar energy installations have almost disappeared from
Spain's energy forecast, no doubt due to changes in energy rates.
Fig. 20 shows the status of installed power versus allocation in the
two major renewable energy sectors, solar and wind. The figure
shows that wind energy will continue growing in the near future.
Given the current energy regulation in Spain, this energy appears
to be more sustainable in the medium term.
