2010 report:
Spain has bolstered its credentials as a world leader in renewable
energy by exporting electricity to France for the first
time. Heavy rain and strong winds during 2010 meant that
renewables - principally hydro, wind and solar power - met 35% of
Spanish demand. In 2010, wind power rose
by 18.5% and now meets 16% of Spain's energy. At its peak, on
November 9, wind power met 43% of demand. Heavy rains saw
hydro-electrical production rise by 59% on 2009. Solar power,
meanwhile, lags behind at only 3%, although some of the big solar
plants have yet to come on stream. Oil and gas continue to generate
about half of Spain's capacity, while nuclear power accounts for around
19%. link
Overview of Spain's role in development of solar power. Spain has an average 340 days of sunshine annually and its
long-term goal had been to produce 400 megawatts of electricity from
solar panels by 2010, and it reached that milestone by the end of 2007.
In 2008 the nation connected 2.5 gigawatts of solar power onto its
grid, more than quintupling its previous capacity and making it second
only to Germany, the world leader. Half the solar power installed
globally in 2008 was installed in Spain. In
its haste to create a solar industry, Spain made some miscalculations:
solar plants could be set up so quickly and easily that the rush into
the industry was much faster than anticipated. Many of the hastily
opened plants offered no hope of being cost-competitive with
conventional power, being poorly designed or located where sunshine was
inadequate, for example. The most robust Spanish solar companies
survived the downturn, have restructured and are re-emerging as global
players. For example, when the government changed course, Siliken
Renewable Energy, originally
a producer of solar panels, shut its factories for five months and cut
its staff to 600 from 1,200. But after shifting its focus to external
markets like Italy, France and the United States, and diversifying into
solar support services, the company now turns a profit. “We were a
company that banks trusted, so we could make the shift,” said Antonio
Navarro, a company spokesman. “But a lot of little companies
disappeared." link (More on solar energy at bottom.) _____________________________________ SOLAR
ENERGY
May 2011: World’s first utility-scale CSP plant that using flat heliostats. Torresol
Energy began operating the world’s first utility-scale concentrating solar
power plant plant that uses flat heliostats and stores heat using molten salt,
allowing it to sustain power through the night for around 25,000 homes in
Seville, Spain. The 19.9-megawatt plant uses 2,650 flat mirrors called
heliostats arranged over 185 hectares of land to heat molten salt. The
heliostats focus sunlight on a tower where liquid is heated up to 900 degrees
centigrade. It is then stored for later use at above 500 degrees centigrade in
tanks beneath the tower. In
total, the power plant avoids more than 30,000 tons of carbon dioxide.

March 2011: Spain runs into solar problems. Spain had one of the world's most
ambitious, and generous, plans to boost the amount of electricity it
generates from the sun. That dream, for the solar industry at least, has turned
sour. Generous subsidies have left Spain with 10 times the amount of
solar pv capacity the government had planned for by 2010 - and a much bigger
bill than it had envisioned. One point on which both the
renewable lobby and the power industry agree: by taking the unprecedented step
of retrospectively cutting subsidies promised to projects which have already
been built, the government risks scaring off investors of all kinds. link
Solar panels
mandatory in new buildings. Spain
wants to take advantage
of its sunshine by making solar panels compulsory in new and renovated
buildings - to save fuel costs and to improve the environment. The Industry
Minister announced that starting
in 2005 anyone who intends to build a
home will be obliged to include solar panels in their plans, with the
aim of
turning Spain
from a straggler to a
European leader in the use of renewable energy. In 2006, Solar panels
are now
compulsory on all new and renovated buildings in Spain as part of the country’s
efforts to bring its building rules up to date and curb growing demand
for
energy. link July 2010: Spain opens the world's largest solar power station
overtaking the US as the biggest solar generator in the world. The
nation's total solar power production is now equivalent to the output
of a nuclear power station. The new La Florida solar plant takes
Spain's solar output to 432MW, which compares with the US output of
422MW. (These totals exclude PV solar panels). link
November 2009: Spain's renewable energy use reaches 25%.
During the first 9 months of 2009, hydroelectric power made up 9% of
all power usage, wind another 9% and solar 3%. Spain has supported the growth of its renewables sector with grants and
subsidies, providing the solar sector with $1.6bn funding in 2008, resulting in
a reported capacity increase of 3,342MW from 695MW in 2007. link The Spanish government is committed to achieving a target of 12% of
primary energy from renewable sources by 2010 with an installed
solar generating capacity of 3,000 MW. Sept. 26 2008 - Industry
Minister Miguel Sebastian said in testimony to the Spanish Senate that
the government expected the capacity of solar panels to expand to 10,000 MW by
2020. link In March 2007, Europe's first commercial concentrating solar power tower plant was opened
near the southern city of Seville producing 11 MW. Abengoa Solar began commercial operation at its new PS20 (20 MW) solar power
tower located near Seville April 2009. link A plant near Granada, known as Andasol 1, began operating November 2008
and now provides 50 megawatts of power, enough electricity to supply 50,000 to
60,000 homes year-round. Solar power plants Andasol 2 and 3 are under construction, with Andasol 2 in the
start-up phase and Andasol 3 expected to be connected to the grid in 2011. The
entire gross output of the plants will total 540GWh per year. link
____________________________________________________________________ SPAIN'S DROUGHT PROBLEMS Spain is
experiencing its worst drought in 40 years.
The BBC
reported in September 2008
that climate
experts warn that the country is
suffering badly from the impact of climate change and that the Sahara
is slowly creeping north
- into the Spanish mainland. link From the
Independent (UK):
Spain’s climate,
like that of the whole Mediterranean region, is inexorably warming up
and
drying out. The political battles now breaking out over water
could be a foretaste of
the water wars that scientists and policymakers have warned us will be
commonplace in the coming decades. Barcelona's
5.5 million
inhabitants need a lot of water: the 19
million litres of water brought by
ship from Tarragona
on 13 May (2008) were enough
for barely 180,000 people and were consumed within minutes of being
channelled
through the city's taps. A later shipment from Marseilles was
bigger, 36
million litres, but similarly short lived. A 200-mile pipeline to
supply Barcelona
with water from the Rhône
in France
is under development. According to the Spanish government one third of the country is in immediate danger of turning into desert. Barcelona Update: July 22 2009: A seawater reverse-osmosis desalination plant opened today will ease the
threat of water restrictions in the Spanish city by producing 24% of the water
consumed by the 4.5 million population.link But desalination has numerous problems and can contribute to global warming - link Perhaps
the most striking image of Spain's drought,, has been that of the
underwater church which emerged from a drying dam: receding waters have exposed the 11th century church at Vic, north of Barcelona completely, Apart
from the far north, the entire country is suffering;
especially the parched areas on the Mediterranean
coast. The government
is building more desalination plants, adding to the more than 900
already in Spain.
However, Spain’s
opposition party, supported by some environmentalists, say that the
ambitious
desalination plant program, with its huge energy needs, will only
exacerbate
CO2 problems.
More than 70% of Spain's water
goes on agriculture, much of it wasted on antiquated irrigation systems
and the
cultivation of thirsty crops unsuitable for arid lands. But few
politicians
seek confrontation with farmers already struggling to scratch a living.

White roofs effects proven in southern Spain: The greenhouse effect may be heating the planet but a new study says Europe's
driest spot, Almeria, Spain, is actually cooling ... thanks to
greenhouses. A group of researchers at the University of Almeria found that the southern
Spanish province had so many commercial greenhouses, seen from space as a white
swathe across the arid province, that they reflected solar energy back into
space. link

Spain is
known for its wine,
a country with more land under vines than any other. But if
temperatures in Spain keep rising - and they have gone up by 2C on
average in the past 50 years - the wines could taste very different and
some vintages will be ruined. more
| Spain's glaciers - now under threat. Spain has lost 90% of its
glaciers because of global warming, threatening drought as rivers dry
up. While glaciers covered 3,300 hectares of
land on the mountain range that divides Spain and
France at the turn of the last
century, only 390 hectares remain, according to Spain's environment
ministry. link |
