A big question in an everyday situation related to advanced technologies or sustainability is that how far the emerging countries are matching the steps with the developed countries. As per the study conducted by Bloomberg New Energy Finance and Climatescope, the investment made by the emerging countries from the last 5 years has seen a rise with a record of 178 billion U.S. dollars invested in 2015.
In another study conducted by Bloomberg, UNEP, FS-UNEP Collaborating Centre, renewable energy has seen major investments from Asia, the Middle East, and Africa. In the last 5 years, Asians have invested from 53.1 to 45.4 billion U.S. dollars whereas the Middle East and Africa invested from 8 to 16.1 billion U.S. dollars.
In particular, India and Brazil counted as major players in emerging countries, recorded 7.7 billion U.S. dollars to 11.4 billion U.S. dollars, investments made by India from 2014 to 2018 whereas Brazil invested 4.3 to 6 billion U.S. dollars from the period 2013 to 2017.
The investment made in renewable energy in 2018 by each region are: –

In my opinion, the situation shows how emerging countries playing a major role in clean energy investment. The active participation by each country provides an analysis of the market worth and hence the contribution is providing the opportunity to invest more in such technologies and make a worth living out of it.
The clean energy investment also shows the heavy activity performed in such an area and hopefully, some return on the investment can be calculated shortly.
