1. Brazil + Russia + India + China + South Africa

2. What are BRICS? BRICS is a term made by the economist Jim O´Neal when he made his thesis of future investment in different countries. These nations have an economy that has progressed steadily in the last 10 to 15 years.

3. Brazils energy sources When we talk about Brazil, we are referring about one of the least polluting countries in the world, if we consider that wind and solar power are being used in public transport. This is reducing pollution in about 46%.

5. Russian energy The largest country in the world makes use of: - Hydropower - Nuclear energy - Solar energy Most of them are in the centre of the territory.

7. Indias energy sources This country is a special case. More than half of Indias energy is generated by coal. Apart from that, there are some other energy sources in the Asian country, such as: solar, nuclear, oil and hydropower. It is known as one of most polluted countries in the world.

9. Chinas energy China is the most polluted country all over the world, taking into account the latest events: the support given to USSR in the Cold War with arms and the nuclear problems with the USA referring to this type of energy in Antartica and the Artic.

11. South Africans energy The most important country in Africa has its consumption coming from different sources such as: coal and renewable energy. South Africa is well known because of diamond mines. Their GNP has enabled the country to become the 15th world power.

13. Case in India (2012 blackout)

14. How it happened? Today Indias energy system basically relies on coal which is still a government monopoly dominated by COAL INDIA a huge company operating coal mines throughout the country. New Delhi was the most affected city in the latest outage.

15. The lights went off The blackout left more than 600 million people without electricity for 2 days. It forced homes and businesses to switch to back-up supplies, halted trains and public transport and caused traffic jams.

16. 60 years of missed targets The blackout highlights the big underlying issue India faces in terms of infrastructure quality. To keep the lights on, India needs to add power capacity, build robust transmission systems, ensure fuel supply and transport and reform power pricing. Most of that is expensive.

17. Conclusion India must go from coal generated energy made by coal and replace it with renewable sources. If this doesnt happen, the Asian country will become the most polluted country in the world. Also, the UN should start curbing the consumption of energy made by coal and oil that waste more than 50% of their resources.

18. Thanks for everything
