Let´s drive electric cars.


Electric cars produce no exhaust fumes, minimal pollution and a third of the CO2emissions of petrol engines. On top of that they're tax free, immune to congestion charges, and a full 'tank' of fuel costs no more than a pint of milk.
How does it work?
  • Electric cars use a battery and electric motor to power the vehicle and are charged via a standard mains socket in your home, or at an increasing number of free outdoor charging bays. The average electric car does 60 miles on a single charge with a top speed of 40mph - while higher performance sports cars can do 150 miles and 130mph.

Wat´s the difference?

  • An electric car run on conventional electricity from a coal-fired generator produces a third of the emissions of a conventional petrol car (64g of CO2 per km compared to 176g CO2 per km) and just over half the emissions of a dieselor hybrid car (104g CO2/km)
  • You can save thousands of pounds a year in running costs

      What's stopping me?

"Max speed, 40mph?"
Electric cars are currently best suited to city driving because the average speed of traffic in London, for example, is notoriously just 10mph: 2mph slower than an Edwardian horse-drawn carriage.
"I've heard they aren't safe"
Electric cars are classified as 'quadricycles' by the Driver and Vehicle Licensing Agency, so are subject to less stringent safety tests than cars. But one report estimates they are three times less likely than petrol cars to be involved in accidents.
"Won't the battery go flat as soon as I get out of my road?"
Current models manage an average of about 60 miles on a single charge so we can make our average daily commute of 17 miles more than three times between recharges.           Source: http://www.bbc.co.uk/bloom/actions/electriccars.shtml

Conclusion :
Personally, I support the use of electrics cars, because they are clean for the enviroment, but it's true if the energy comes from a non-renovable source, it's a lose of time and money.

Malaga C.F against climate change

The departament of Environment and the Malaga Football Club have signed an agreement to promote urban sustainability against climate change, reducing the environmental impact of sport and business in general. Through this agreement, signed by the director of the Department, Jose Juan Diaz Trillo, and the club's general manager, Fernando Hierro, the "Junta" will advise the Malaga to minimize the environmental impact of its installations´ activities, contributing to reducing their emissions of greenhouse gases and promoting the development of a more sustainable city.

The club is going to do an audit of emissions of greenhouse gases generated by their activity in the coming months . After obtaining the results, with the collaboration of the Ministry, it will design a a plan to reduce emissions and offset them through the Andalusian Emission Offset (SACE) of greenhouse gases. Malaga will work also developing a mobility strategy that promotes the use of public transport instead of the private car, such as bicycles.The waste collection in sports installations, implementation of measures to reduce noise pollution, are other activities that develop the club.
The objective of the Junta is to sign similar agreements with major sporting organizations in the region. Source: http://www.diariosur.es/videos/malaga/actualidad/1437055992001-malaga-junta-lucha-contra-cambio-climatico.html
Conclusion:
I like that my football team is against climate change, because football is one of the best ways to arrive people, and change or try to concern them about this serious problem.
but it's a little step in the long way that we have to walk. I hope that in a certain future all football teams are fighting against climate change.
 


Climate Change: My experience educating others

Most people knows the climate change but are we concerned about it? Just see it:

The climate change
My experience showing the presentation was interesting because it´s the first time that I had to a job like this, and it´s important for the future control these situations in which you are in front of a public who expects your best work. In my opinion it was easy showing it, the questions were the difficult part where you have to be alert and to prove your knowledge.

Reducing the annual emission of 1000 million tonnes of carbon

For the year 2057

Efficiency
and conservation: 

Improve the performance of the vehicle fleet from 12 km / L to 25km / L fuel.
Reduce the distance traveled per car per year: from 16,000 km to 8,000 km.
Improve the efficiency of air conditioners, heating and appliances 25%.

Generation of energy:
Imporve the efficiency of carbon power plants from 40% to 60%.

Replace 1400 energy production plants based on carbon thermal by plants based on natural gas,is less contaminating.
CO2 Capture: 
Install CO2 capture systems in 800 carbon-fired power.
Use of CO2 capture systems in energy-producing plants (from hydrogen) can supply 1500 million cars.
Install CO2 capture systems in synthetic fuel installations derived of carbon that produced 30 million barrels of oil a day.
Alternative energy sources:
Triple the production based on nuclear energy replacing carbon plants.
increase the production of wind energy by a factor 40 displacing carbon power plants.
increase solar energy production 700 times.
increase 80 times the production capacity of wind power to supply hydrogen to vehicles.
Using 2000 million vehicles that consume ethanol. This will need to spend a sixth of the area of the earth to generate energy crops.

Agriculture and forestry:
Stopping deforestation in all regions of the planet.
Extend conservation agriculture all cultivable land on the planet (not to release more CO2).

Food and Climate, The Developing Crisis

  • In developing countries, climate change will cause yield declines for the most important crops. South Asia will be particularly hard hit.
  • Climate change will have varying effects on irrigated yields across regions, but irrigated yields for all crops in South Asia will experience large declines.
  • Climate change will result in additional price increases for the most important agricultural crops–rice, wheat, maize, and soybeans. Higher feed prices will result in higher meat prices. As a result, climate change will reduce the growth in meat consumption slightly and cause a more substantial fall in cereals consumption.
  • Calorie availability in 2050 will not only be lower than in the no–climate-change scenario—it will actually decline relative to 2000 levels throughout the developing world.
  • By 2050, the decline in calorie availability will increase child malnutrition by 20 percent relative to a world with no climate change. Climate change will eliminate much of the improvement in child malnourishment levels that would occur with no climate change.
  • Thus, aggressive agricultural productivity investments of US$7.1–7.3 billion are needed to raise calorie consumption enough to offset the negative impacts of climate change on the health and well-being of children.

Don't Wait for Too Little Too Late: Ideas for now to stop climate change

A short list of relatively simple actions taken to reduce greenhouse gases other than CO2 could help put the brakes on global warming.
The 14 measures that would immediately slow global warming are:

—Eliminate methane releases from coal mines—particularly in China—by capturing it and burning it.
—Eliminate the venting or accidental release of methane co-produced by oil drilling (and, of course, gas drilling itself), particularly in Africa, the Middle East and Russia.
—Capture gas from landfills in the U.S. and China as well as promote recycling and composting of biodegradable trash.
—Occasionally aerate flooded rice paddies to prevent the growth of methane-producing microbes.
—Stop leaks from natural gas pipelines, particularly in Russia.
—Use bio-digesters—vessels in which microbes break down manure into gas—to cut methane from livestock globally.
—Update wastewater treatment plants to capture methane.
—Filter the soot produced by incomplete combustion of diesel fuel in vehicles, and attempt to eliminate inefficient internal combustion engine vehicles entirely.
—Replace indoor cooking and heating fires with clean-burning cookstoves fired either by wood, manure or other biomass or, even better, methane.
—Replace traditional brick kilns with more advanced firing methods.
—Replace traditional ovens for turning coal to coke with modern technologies.
—Ban the open burning of crop stubble and other agricultural waste.

The researchers estimate that cutting those 14 together could avoid between 700,000 and 4.7 million premature deaths (largely from smoky, unhealthy air) and increase crop yields by between 30 million and 135 million metric tons (due to concomitant reductions in ground-level ozone, otherwise known as smog, which forms from fugitive methane and blights crops in Brazil, China, India, the U.S. and elsewhere). In addition, the economic analysis suggests that many of these measures provide more value in benefits than they cost to implement.

Climate Change's Biggest (And brightest) Supporters: Celebrities Supporting Change

There are a lot of celebrities that supports climate change, some of them said their opinion about it in Copenhagen climate conference:


Leonardo DiCaprio
The Prius-driving Hollywood star is the leading climate change celebrity.
DiCaprio has received praise from environmental groups for opting to fly on commercial flights instead of chartering private jets.
His actions have inspired other celebrities, such as Orlando Bloom and Penelope Cruz. Co-wrote, co-produced and narrated the film 11th Hour and cites global warming as "the number one environmental challenge."

Cate Blanchett
Australian actress Blanchett has been involved in promoting tough environmental policies down under in Australia for many years now, through lobby group whoonearthcares.
Most recently, the actress appeared in Copenhagen in May of this year at the World Business Summit on Climate Change. The actress addressed business leaders, urging them to decrease their carbon emissions and increase sustainable practices.
“Political failure at Copenhagen in December is quite simply unacceptable and this powerful room must play a major role in preventing this failure,” she said.


Sting
An early convert to the environmentalist cause, particularly the Save the Rainforest movement. A species of Colombian tree frog, Dendropsophus stingi, was named after him in recognition.
Though Sting’s personal carbon footprint regularly comes under scrutiny, the famous singer is backing Prince Charles’ Rainforests Project — which seeks to limit deforestation and buy the world time to move to a low-carbon economy.
Ahead of the Copenhagen Talks, Sting has lent his iconic “Message in a Bottle” song to the campaign — sending a different kind of SOS to the world
Global Cool, an environmental charity which has enlisted celebrities such as KT Tunstall to help to make saving energy an "aspirational lifestyle", gives them all "carbon coaching" to help them to reduce their footprints. It aims to encourage a billion people worldwide to take steps to reduce their carbon emissions by one ton per year.
Hollywood heart-throb Josh Hartnett is a Prius-driving vegetarian; has backed also Global Cool since its inception

Miley Cyrus
The frothy teen-queen might not be immediately associated with the great issues of the day but on her recent album she produced the consciousness-raising track, Wake Up America.
The chorus went: Wake up America/We're all in this together/It's our home, so let's take care of it/You know that you want to You know that you got to/Wake up America/Tomorrow becomes a new day/And everything you do matters/Yeah, everything you do matters in some way

Taking Steps Right Now: A Concert at IES El Palo

This was a concert that we showed for our school with the porpouse of have fun and concern people there is a future that looks dark and we have to change that image for the good of all of us..
Enjoy watching it http://www.youtube.com/watch?v=N0lcaSox6H8

What's new?

In many countries cientifist had developed some ideas for new renewable energies. Some of those ideas  sound crazy, but they are true, such as a seaworm that is in the ocean that use the movement of the waves and converts into energy, also there are other proposals that consist in use the waste of the farms for vehicles, if you want to now more about this new way of get healthy energy, just click on that link   --> http://www.renewableenergyworld.com/rea/home

Act Now My Friend!

The future is coming, and the consecuences of what we do with our planet, started some years ago. For example in the USA there used to be a huge forest, and now from the space you can see how brown is because of the deforestation..https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjlfPJnzc0mML604zuXnutGrrGWoYKoZXiCS8dbszd0-C0ztNc7heK3yyW0tg1Q0ENQEoBNo1CD7VPTqRT4q-gQK0CDL6q-zPD0jXCqIX5WQ4K1E8URmabloQKb2wV2OSwodqCBj_PnWg/s1600/de-bosques-a-desiertos.jpg there are a lot of examples that we haven't realize yet, but they exist and we have to change this, is very easy to help the enviroment, if you follow some of the basic rules you can make in a little measure a big change:

-If you are listening to music, use headphones instead of speakers this doesnt contaminate too much, but helps to reduce the db in your zone.

-If you live with your family try to use only one tv when you are watching at it.

-Keep close the windows in winter to mantein the warm in the house

-Life near the city center is use to be very pollute, so try use public transport or even bike if you want to move in the sourroundings of the city center.

-If you have enough space to grow a little farm in your balconi, why don't you try to built one by yourself?

-If you have to study a lot, try to start from the morning in the sun light, because is healthier and helps also to concentrate in your studies.

-Buy products that aren't exported from other countries, it helps for the economy of your country and also doesn't contaminate because of the transport.

-Try don't use electrical machines to warm, because the 70% of the energy is lose before coming home.

My Experience: Jorge & Ádam, their presentation


Danger: climate change is not a joke

Some people say climatre change is an invention because the climate in the earth has changed always in the history and now it is not different from the other times, they say we can not do nothing against it. And instead of helping us they continue destroying our life in the earth while we are trying to fight against the problem. Because of these people, and all the other people with many reasons for not helping with it, this problem is going to convert in a catastrophe.

This message is for all that people who do not believe in the problem:

maybe you are not going to die, maybe your children neither but they are not going to live very well as you, if you continue with this your grandchildren are not going to live, and this is talking about your family, you have to think globaly.

if you have changed your opinion and you want to help us, here are some ideas that you can do easily:

-using energy efficient vehicle
-using public transport
-recycling
-reusing things
-suporting clean energy
-teaching this problem to other people

and here you can see a presentation where maybe you can find evidence of this huge problem:

Renewable Energy, A Summary

Is the energy which comes from natural recurses.There is few renewable energy.There are different types of renewable energy: wind power,hydro power,solar energy,biomass,biofuel and geothermal energy.Coal or gas are not renewable.This type of energy is clean energy,each time we use more renewable energy because it`s a way to produce power without pollute.The problem of this type of energy is more expensive than others so the goverment don`t have money enough to pay it.
