Green PerVisor

 Based on REN21's 2016 report, renewable energy contributed to 19.2% o global energy consumption. By 2015, worldwide investments in renewable technologies amounted more than US$286 billion!
 This article lists the countries generating the most electricity from renewable sources in 2016. This represent the energy that they import and/or export electricity, so it's not based on their consuption.

The list of the 25 countries who have the biggest renewable energy production are:

1. Albania (100%)
2. Democratic Republic of the Congo (100%)
3. Iceland (100%)
4. Paraguay (100%)
5. Namibia (99,3%)
6. Costa Rica (97,7%)
7. Tajikistan (97,5%)
8. Norway (97,2%)
9. Uruguay (96,5%)
10. Zambia (95,0%)
11. Ethiopia (93,6%)
12. Kenya (90,7%)
13. Kyrgyzstan (86,7%)
14. New Zealand (83,9%)
15. Mozambique (83,7%)
16. Georgia (80,7%)
17. Brazil (80,4%)
18. Korea DPR (75,7)
19. Austria (74.3%)
20. Togo (73,1%)
21. Angola (70,3%)
22. Gabon (68,4%)
23. Venezuela (67,6%)
24. Panama (66,6%)
25. Republic of the Congo (66,4%) 

It's good to watch that exists already 4 countries who produce 100% of their energy from renewable sources, and its even really good that places like the European Union, where they're goal, its to reach by 2050 the neutrality of greenhouse gas emissions.

By 2050, Europe desire to get a neutral impact on the emission of CO2, reducing between 80 and 95% of emissions.
In the US, by 2050, the Wind Power will be responsible for the 35% of eletrical production.
To measure the efficiency of each source we are taking in count the cost of the fuel, the cost of production, and the cost of dealing with the environmental damages.

The most efficient types of Renewable Energy are:

1. Wind
2. Geothermal
3. Hydro
4. Nuclear
5. Solar

The Wind Power, as the winner have a lot of advantages, like:

1. As January of 2016, it was providing 88 000 jobs only in the United States;
2. Generates over $128 billions in private investment between 2008 and 2015;
3. Doesn't pollute the environment;
4. Has low operation costs.
