AUDIO: Energy independence El Hierro Island goes straight to 100% renewable energy

 .http://www.npr.org/blogs/parallels/2014/09/17/349223674/tiny-spanish-island-nears-its-goal-100-percent-renewable-energy Audio Tiny Spanish Island Nears Its Goal: 100 Percent Renewable Energy NPR, by LAUREN FRAYER September 28, 2014 “….. Spanish island of El Hierro. The ancient island off the west coast of Africa is now a model for the future, within months of running on 100 percent renewable energy, which consists of a mix of wind and hydro-power.

El Hierro, the most remote of Spain’s Canary Islands, is now billing itself as the world’s first energy self-sufficient island that has never been hooked up to a power grid.A Danish island, Samso, is also energy-independent, but was previously hooked up to the Danish grid and didn’t make the change in isolation, like El Hierro.

Because of the topography of the surrounding seabed, El Hierro, an active volcanic island with a population of about 10,000, could never hook up to Spain’s power grid.

Instead, it used big barges to ship in 6,600 tons of diesel fuel — the equivalent of 40,000 barrels of oil — each year, to power electricity generators. It was an expensive, time-consuming and dirty endeavor … until now.

This past summer, El Hierro inaugurated the Gorona del Viento power plant, a $110 million wind and water turbine farm. By the end of this year, the plant will generate all of the island’s energy needs of up to 48 gigawatt hours per year……..

El Hierro is already planning its next energy project. It wants all the island’s cars to be electric by the year 2020.

Spain’s increasing solar radiation

Solar Radiation Increasing In Spain Red Orbit, June 6, 2013 FECYT – Spanish Foundation for Science and TechnologySolar radiation in Spain has increased by 2.3% every decade since the 1980s, according to a study by researchers from the University of Girona and the Federal Institute of Technology (ETH) in Zurich. This increase is linked to the decreased presence of clouds, which has increased the amount of direct radiation reaching us from the Sun.

“The mean annual G series over Spain shows a tendency to increase during the 1985-2010 period, with a significant linear trend of + 3.9 W m-2 [2.3% more] per decade.” This is the main conclusion of a study published in the magazine ‘Global and Planetary Change‘ by researchers from the University of Girona and the Federal Institute of Technology in Zurich (ETH, Switzerland).

The season-by-season data show the same “significant” increase in solar radiation impacting the nation: + 6.5 W/m2 per decade during the summer, + 4.1 W/m2 in autumn, + 3.2 W/m2 in spring and + 1.7 W/m2 in winter.

“These data relate to global solar radiation, in other words the increase in direct radiation reaching us from the Sun plus diffuse radiation which is scattered previously by clouds, atmospheric gases and aerosols,” explains one of the authors, Arturo Sánchez-Lorenzo, currently a postdoctoral researcher at the University of Girona…… According to the scientists, this increase may also go hand in hand with more ultraviolet rays, an excess of which presents a health risk, potentially leading to skin cancer.

More global brightening

The increase in global solar radiation is a phenomenon that has been observed in other parts of the world for almost 30 years, especially in developed countries, and it has been named “global brightening”. The fall in the diffuse component has also been observed in Central European and Eastern countries.

The team behind the study has not yet analyzed the solar radiation data for 2011-2013 provided by the Spanish State Meteorological Agency, but the data from other European weather stations suggests that this brightening is still on the rise.

“Studies such as these may be of interest to the solar energy industry, especially in countries like Spain, where not only do we already have a lot of direct solar radiation but now we are getting even more,” affirms one of the other authors, Josep Calbó, who is a professor at the University of Girona. http://www.redorbit.com/news/science/1112866837/solar-radiation-increasing-spain-060613/

Spain’s Andalusia solar power station produces electricity day and night

Solar power station in Spain works at night  Yahoo Finance 19 Mar 12, A unique thermosolar power station in southern Spain can shrug off cloudy days: energy stored when the sun shines lets it produce electricity even during the night.

The Gemasolar station, up and running since last May, stands out in the plains of Andalusia.

From the road between Seville and Cordoba, one can see its central tower lit up like a beacon by 2,600 solar mirrors, each 120 square metres (28,500 square feet), that surround it in an immense 195-hectare (480-acre) circle.

“It is the first station in the world that works 24 hours a day, a solar power station that works day and night!” said Santago Arias, technical director of Torresol Energy, which runs the station. The mechanism is “very easy to explain,” he said: the panels reflect the suns rays on to the tower, transmitting energy at an intensity 1,000 times higher than that of the sun’s rays reaching the earth.

Energy is stored in a vat filled with molten salts at a temperature of more than 500 degrees C (930 F). Those salts are used to produce steam to turn the turbines and produce electricity.

It is the station’s capacity to store energy that makes Gemasolar so different because it allows the plant to transmit power during the night, relying on energy it has accumulated during the day.

“I use that energy as I see fit, and not as the sun dictates,” Arias explained.

As a result, the plant produces 60 percent more energy than a station without storage capacity because it can work 6,400 hours a year compared to 1,200-2,000 hours for other solar power stations, he said.

“The amount of energy we produce a year is equal to the consumption of 30,000 Spanish households,” Arias said, an annual saving of 30,000 tonnes of CO2.

Helped by generous state aid, renewable energies have enjoyed a boom in Spain, the world number two in solar energy and the biggest wind power producer in Europe, ahead of Germany. … http://au.finance.yahoo.com/news/solar-power-station-spain-works-020347254.html
