Working about the loss of biodiversity

img_20161114_104946

IES Sáenz de Buruaga has started to work in the new block of the project Loss of  Biodiversity . We have prepared several activities in this block . The first one has been a special activiy with a educational bus where expert of the Extremenian administration have been explainig interesting knowledges about invasives species . We have learnt that pets as squirrels or turtles can become dangerous species which can eliminate other native species.

Spanish students interview to Environment Councilman of Mérida about the climate change

IMG_4075Spanish students have had a meeting with the Environmental councilman of Mérida Rafael España Santamaría He told us that the council town is taken measures in order to control the emisions of CO2 to the atmosphere. allthough is not a clear legal competence of this institution in Spain.

The council town is working in three priority lines : promoting he public transport, improving the energy efficiency of the municipal buildings and focusing on renewable energies .

During one hour the council man has been talking witih our students about environmental municipal policies  and has conveyed us his concern about the climate change and the need to do something in all areas of our life against the greenhouse effect. He has invited us to use the public transport and especially to go walking to everywhere in Merida and in this way to enjoy our city .

This experience has been very interesting for our students given that this is their first contact with a politician with responsabilities on environmental matters  speking in English.

November 7th we visited a sustainable industry: Nordic Sugar in Örtofta, Sweden

Nordic Sugar Örtofta is one of the largest and most efficient sugar-producing facilities in Europe.

During the production season, called the campaign, and running from mid-September to mid-January the facility operates around the clock, seven days a week. In this period Nordic Sugar Örtofta receives and processes around 2 million tones of beet, turning this volume into high- quality sugar and feed products. Around 600 truckloads of beet are delivered to Örtofta every day of the campaign. The sugar beets are supplied by approx. 2,000 beet growers. The facility has a daily processing capacity of 18,500 tonnes of beet.

Annual production in Sweden (2014/15):

382,000 tonnes of sugar

Beet-based feed products:

69,000 tonnes of HP-Pulp

4,000 tonnes of molassed sugar beet pellets

58,000 tonnes of molasses

 

Approximately half of the white granulated sugar output is sold to the retail market under Dansukker ® brand, the other half to the food industry. Nordic Sugar Örtofta also handles Nordic Sugar’s Fibrex® dietary fibre production at Köpingebro plant.

The site employs around 160 people. During the production campaign close to 80 seasonal workers also there. The majority of the employees are engaged in the production as machine operators, process operators and service engineers (within electrical maintenance or automation), as well as at the laboratory.

Surplus heat benefit households in Lund, Lomma and Eslöv

Örtofta also transfers heat to Lund and Eslöv via a district heating pipe so that the energy from the sugar mill is not wasted. Örtofta Agency is a biomass power plants that produce heat equivalent to half the district heating demand in Eslöv, Lund and Lomma (500 GWh) and electricity to meet the annual requirement of Eslöv (220 GWh)

Nordic Sugar’s Örtofta plant in Sweden started the beet campaign on 11 September. This year, the company expects to increase its supply of surplus heat to energy company Lunds Energi. Close to 50,000 households stand to benefit from the increased supply of surplus heat as Lunds Energi has combined the district heating grids in Lomma, Lund and Eslöv.

Spanish students take care of the mountains

img_20161102_150548

Students from the IES Saénz de Buruaga have been in the mountains of the North of the province of Cáceres( Extremadura)  in order to enjoy of a walk and clean up the pathways through the mountains .

Unfortunately people don´t care an marvellous environment as the mountains are so we can find a lot of trash when we are walking on these areas as trash bags, bins , food waste and others..

However our students enjoyed on the mountains

Spanish students are working on an exhibition about the climate change

exposicion4

Students in Merida are working on an exhibition about the Climate change. This exhibition has been donated by our regional government to our school  for several weeks . All the groups are working with a material made by our teachers. This exhibition was made in 2006 when the problem was not so big . In this way our students are very concerned because of the high temperatures in Mérida in this autumn.

In these photos you can see students from the group of 1º ESO working . as you can see they are wearing summer clothes and we are in November !!!

Energy trees by NewWind and nice looking solar roof by Tesla. Clean energy for the future available today.

 

Energy trees

In The Green Energy Blog you can read about very hopeful news.  A tree that looks like a piece of modern art provides the town with clean and renewable energy. Each tree has a current power output of 3.1 kilowatts, which might not be able to power much on its own. However, using several of the trees together, they can supply the surroundings with energy.

The trees are 11 meters (36 ft) tall, and 8 meters (26 ft) in diameter at its widest point, which makes it about the same height as many urban trees. The white frame of the tree is made out of steel, and it can hold 72 turbines that sit vertically. This orientation cancels out noise, allowing the turbine to spin silently. Wind turbines are typically very tall in order to reach the altitude where the wind is stronger, but these vertical turbines are able to spin with wind blowing as low as 7 km/h (4.4 mph), making this twice as sensitive as traditional turbines. However, they are durable enough to withstand Category 3 winds, which can reach 178 – 208 km/h (111-129 mph).

Each turbine “sheet,” called an Aeroleaf, is constructed out of lightweight plastic. The plastic has been treated with a resin which protects it from weather conditions such as humidity and salt (for areas close to the sea). The turbines are wired in parallel so that if one stops working for whatever reason, the others will not be affected.

The energy of a wind tree can supply 83% of the electrical consumption of a French household, excluding heating or loading an electric car for 16 000 kilometer per year.

Nice looking solar roof by Tesla

Tesla founder and CEO Elon Musk wasn’t kidding when he said that the new Tesla solar roof product was better looking than an ordinary roof: the roofing replacement with solar energy gathering powers does indeed look great. It’s a far cry from the obvious and somewhat weird aftermarket panels you see applied to roofs after the fact today.

The solar roofing comes in four distinct styles that Tesla presented at the event, including “Textured Glass Tile,” “Slate Glass Tile,” “Tuscan Glass Tile, and “Smooth Glass Tile.” Each of these achieves a different aesthetic look, but all resembled fairly closely a current roofing material style. Each is also transparent to solar, but appears opaque when viewed from an angle.

Tesla’s product improve the cost of the home , by generating enough energy to fully power a household, with the power designed to be stored in the new Powerwall 2.0 battery units so that homeowners can keep a reserve in case of excess need.
