Energy Efficiency is in our daily invention habit

 Energy efficiency comes with a whole range of benefits and opportunities: from health to finance improvement.

We do not have to be inventors or actors to create changes towards a greener planet; we can start by buying a plant, avoid putting extra water to be boil  in the kettle, take a shower 5 second sorter and we will be improving.

There are many thing we can do but we do not even think about them. People get electric cars, what about to get a bike?.  Biking is a good way to avoid jams and do exercise.

Energy efficiency can be achieve by many ways. For example with the housing election, a house could be far more expensive in energy terms that a flat and also the area is a key points. If you live in an area where you have to move to go to buy, to take children to school, go to work... then you have to expend energy and time to shift.  I am not sure it is well known the fact that cities allow for huge savings in energy terms.

Also the recycling of things, the second hand market is a huge way to both save and recycling. By using imagination we can give other uses to objects (for example I am using cardboards boxes as furniture in some part of the house). I have found that a lot of people do not like to buy second hand objects, however they usually cost a fraction of the initial price and in many case they are just slightly old and deteriorated.

There are many ways to avoid wasting not only money but limited resources and need to open our eyes and be creative to give other uses to objects.

Electric versus Combustion cars

Electric cars are every day becoming more sounding. We can see futuristics models in tv, and in daily bases I can see the Nissan Leaf and Tesla S in my area.  

Although most of the attention in the inclusion of renewable energy in the motor sector rely on the electric car, I wonder about the other alternative, the biofuels. I cannot find anything in the UK. Apparently fuel you buy in the UK can with a little percentage of biofuels (less than 5 %). However is well-known that in countries like Brazil the size of the market of biofuels is just huge (see in wikipedia). It is possible that the introduction of biofuel is only profitable in Ecuadorian countries however there is a relative good inclusions in countries like EEUU or Sweden.

In theory most of the engines could use a biofuel version without big problems, but a reduction of the power and the range. Apparently there is a cost if you want to adapt  your car. But this is not the only cost, you have to search for the biofuel and it looks  that there is not a big enough net in the UK.

Most of the industrialized big economies have a agricultural sector that could be potentially structured and it could be an interesting direction. It could keep a more local approach to the energy production.

The technology are moving toward the creation of biofuel to be used in car from wood, something very interesting because it could increase the range of possibilities.

It is exciting to see all this technologies heading in one direction let's see what happens in the next future.

The Syrian's mess, Calais's jungle and information

Today I was checking the news an I was surprise by the new of of a military "parade" or Russian military ships near UK, and it makes me think about the reason: aparently the ships are in their way to Sirya, what makes me focus in Syria and I have realice that Sirya is on war for years now. 

The Calais Jungle appears in the British news daily, I know people volunteering their and I know refugees from the area. What is going on in there? In my search for information I have found that in the military actions there are involved Russia, EEUU, UK, France, Irak Iran and  other countries. What it become such a mess? How can it be I do not know exactly what is doing the British military there?

I do not, even when I check daily Spanish and British news. How can I do not know? It also happening to most of the people I know, you ask about this particular topic and they are totally lost.

Do we have to little information or to much?

Wonder Women and Gender Inequality

Wonder Woman has become a UN embassador which apparently is controversial.

I recall a conversation of my mother and others women talking about the differences of female and male teachers (in the eighties in rural Spain). Today we have a women as a Primer Minister in the UK, and a democrat females candidate for the White House, are we advanced in terms of gender inequality? what is gender inequality?.

To try to understand a little bit more I have been searching a little bit for what is going particularly in the UK (the UK is a very dynamic society where little effects can lead to effect in prices significantly, for example, a) if you have a car and change your neighborhood for another you may find that you have to pay less o more money of car insurance or b) if you search for a house you will see  that a very similar house change its prices for the distance to shopping center, bus lines and so on).  So I have a look to a couple of reviews of the topic  and suggestion to help (here and here).

There are ideas about the role of women and men in society, however there is also a strong economic component in the decision or employment of those roles (consciously or unconsciously).

I do not think I am going to find here in half an hour the answer, solution or not even the right question but it makes me think a little bit: this thought lead to life balance and this is a topic than religions are working on it for millenniums. I also think it is very important to account for the views in decision of every single group in the society.

I think that most of the result come out from "cold" wages  and "warm" sharing self reported information.  I mean cold in the sense that it just an objective number  (it appears in the bank account) and warm that someone self report something in biased (I think I do this thing better or more that other person) by construction.

Some of the conclusion of  previous reports is that women tend to spend more time in chores and at home than men and men tend to earn more money and work full time outside home. I wonder if there is and objective/rational way to think this is good or bad or where is the best allocation to get a good balanced. I do not know where is the balance.

I am afraid that men could tend to work outside home more because they general imperative  culture and better salaries and women then to work more within the family realm for the same reason and they both resent to do that. I mean women may think men are better off and viceversa. Which could take a solution to try to do everything in halves. Is this the fair allocation? is it the balanced point?

Diclousure: I am a man.

Collect GDP forecast using OCDE API with python 3.4

Collect GDP forecast using OCDE API with python 2.7

Rafael Valero Fernandez 14/10/2016
Gather data using OCDE API (After writing this entrances I realice a possible easier way, by using padas data reader: https://pandas-datareader.readthedocs.io/en/latest/remote_data.html#oecd)
Step 2) Read the previous link with python
Step 3) get the json
Step 4) Parse json into dataframe pandas
