There are still more than 300 authorized hazardous products for bees

Thanks to the thousands of signatures across Europe for bees are now four banned toxic insecticides. However, they are temporary and partial bans. In Spain there are still allowed 319 dangerous products for bees. So we ask you to sign to require the Spanish Government:

Set a timetable for banning the most harmful pesticides (imidacloprid, clothianidin, thiamethoxam, fipronil, chlorpyrifos, deltamethrin and cypermethrin).

Bees are disappearing and with them many other pollinating insects that are essential for the development of major crops intended for human consumption in Spain. Therefore, and for the love he professes to these insects, the beekeeper Jesus Gonzalez coordinates the project “Adopt A Hive” where hives sustainably managed and partners can sponsor one to change honey. «Bees can be saved. The key is to create a strong empathic bond with them that impels us to act. We need people to love and want to bees as any other animal or pet» Alejandro Panés (@AlexKafiri) proclaims.

“We no longer remember their buzz and honey we eat is a substitute” he says. Children grow up not knowing how their sting hurts or how it smells a flower. Kiwis, pumpkins, melons, watermelons, zucchini, apples, peaches and almonds have become luxury products, at least the truth. We have reacted late. Overexploitation of hives in manufacturing and indiscriminate use of herbicides and pesticides have dented. Bees can not live in the world we have created.

The above paragraph may well be accompanied by a dark melody, a sharp cry and a certified ‘dystopian product’ label. Unfortunately, it’s not that far from reality. In southwest China, farmers pollinate their apple and pear trees by hand. In Spain we run the serious risk of following in his footsteps. Fortunately, there are still people who have not given up. Jesus Gonzalez takes a lifetime keeping bees and four years as head of Adopt a Beehive in Pedro Bernardo, Ávila. An ecological and sustainable project that puts their bit to overcome this problem. «Bees pollinate up to 160,000 species of fruit, flowers and trees. Of all these, they alone are concerned with the 80 percent», Jesus says. He is convinced that can be saved. Everything happens for creating and strengthening the bond between people and bees.

Reluctantly, the bees are disappearing and with them many other pollinating insects such as bumblebees — How long haven’t you seen one? —, butterflies and others. In a Greenpeace study, entitled Food under threat, the NGO states that nearly three quarters of major crops for human consumption in Spain depend on pollination by these insects. Something extremely relevant to food level, but also commercial, since Spain is the second largest producer of almonds, peaches and nectarines quarter and third of strawberries, crops belonging to the most vulnerable to lack of pollination by insects. Furthermore, Spain is the EU country most important in terms of honey production, with 17 percent of the total community census.


For its part, the European Union has been made to quantify the depopulation of beehives and identify the causes. In April 2014, the European Reference Laboratory for bee health (EURL) published the results of the first active surveillance program on mortality in bee hives (EPILOBEE). The research was conducted on more than 30,000 hives of 17 members throughout 2012 and 2013 and, in addition to counting deaths, collected agricultural practices and clinical manifestations of the most prominent countries infectious and parasitic diseases. In winter, most delicate time, mortality ranged between 3.5 percent and 33.6 hive. The countries of northern Europe were the most affected with figures above 20 percent while Spain and other Mediterranean countries lost less than 10 percent of the hives studied. However, these data contradict those of the Spanish beekeeping, published in the study of Greenpeace, who claim that the mortality in our country was between 20% and 40 percent. Something is wrong here.

     Develop a comprehensive action plan to protect bees and other pollinators and set a roadmap to increase to 7.6 million hectares the area devoted to organic farming in 2020.

From today's actions depend on future generations of humans and other species.Firm to ask the Spanish authorities to protect the bees! see more at Que-puedes-hacer-tu/Ser-ciberactivista/salvar-abejas/

#Acciona 2 #Deploy the Biggest #LATAM #Solar #PV plant in #Chile, a 343M$ #Investment

  • "Rosemary Solar": 247MWp 2 generate 505 GWh per year, the "El Romero Solar" Plant In Atacama Desert will have a maximum capacity of 247 MWp (196 MW rated power) and will deploy more than 777,000 solar modules on a site covering 691 Acres
  • ACCIONA Energía will start construction work on the plant soon, and it will be operational in mid-2017


ACCIONA Energía will construct the biggest photovoltaic plant in Latin America –El Romero Solar- in Chile, with an investment of 343 million dollars (307 million euros at current exchange rates). Located in the Atacama Desert, it will have a maximum capacity of 246.6 megawatts (MWp) -196 MW rated power-, making it one of the ten biggest photovoltaic complexes in the world to date. 
Construction work on El Romero Solar will begin soon, with a view to start-up in mid-2017. This will enable the company to cover a large part of its commitment to supply 600 GWh of electricity from renewable sources to distribution concession holders in the Central Interconnected System (SIC) from 2018 onward. This capacity, awarded in a tender in 2014, will represent an investment of around 448 million euros (US$ 500 million) for ACCIONA.

The power produced in the plant will be used to cover other renewables-based electricity supplies in the country.
The new photovoltaic plant, located in the municipality of Vallenar (Region of Atacama) 645 km north of the capital Santiago, will produce around 505 GWh of clean energy a year, equivalent to the electricity demand of 245,000 Chilean homes and avoiding the emission of approximately 485,000 metric tons of CO2 to the atmosphere every year from coal-fired power stations.
ACCIONA Energía CEO Rafael Mateo points out that “the start of construction work on El Romero Solar is a very significant milestone, one that will enable us to respond to our commitment to supply renewables-based power in Chile and strengthen our role in the country’s energy sector. We are very pleased to contribute to the availability of clean, quality energy in Chile through what will be our biggest photovoltaic plant in the world”.
 A SURFACE AREA EQUIVALENT TO 211 SOCCER PITCHES
The El Romero Solar plant will cover 280 hectares in the Atacama Desert, one of the driest places on the planet. It has a high level of solar radiation and very clean air, which facilitates the capture of the sun’s energy. These factors have been crucial in the installation of astronomical observatories in the area.
The plant will be equipped with 777,360 polycrystalline silicon photovoltaic modules, making up a solar capture surface of over 1.5 million m(equivalent to 211 professional soccer pitches). The panels will be installed on static metal structures which, if lined up, would have a total length of over 111 kilometers.

PRESENCE IN CHILE

El Romero Solar will be the second asset owned by ACCIONA Energía in Chile after the 45 MW Punta Palmeras wind farm located in the region of Coquimbo.
ACCIONA Energía is also carrying out projects for third-party customers in Chile. It has built the first phase of the 7.2 MW Pampa-Camarones photovoltaic plant for the developer E-CL (GDF-Suez Group) and has other projects in its portfolio.
For its part, ACCIONA Windpower has supplied fifteen AW116/3000 wind turbines for Punta Palmeras. They have the highest operational capacity of all the turbines in Chile. In previous years the company manufactured forty AW1500 turbines for a wind farm owned by third-party customers.
As a group, ACCIONA has been present in Chile since 1993, initially through its Infrastructure Division with major projects to build highways, hospitals, hydro plants and other infrastructure for the mining sector. In the water business, ACCIONA designed and built a large desalination plant for the mining industry (Copiapó). It also undertakes the operation and maintenance of other plants and has constructed several wastewater treatment plants.

EXPERTS IN PHOTOVOLTAIC POWER

ACCIONA Energía has more than 15 years’ experience in the design, construction and operation of large photovoltaic plants. During this period it has installed 24 plants with a total capacity of 234 MWp, of which it owns 143 MWp, and has installed 91 MWp for third-party customers.
Among them, it is worth highlighting the Sishen (94.3 MWp) plant in South Africa. It was grid connected in December 2014 and has the highest production level of the entire African continent. Then there is the Amareleja plant in Portugal, with 45.78 MWp. Therefore, El Romero Solar will be the biggest PV plant installed to date by ACCIONA Energía and will easily surpass twice the capacity installed by the company in this renewable technology so far.
