3) Cuba
Cuba has always been a relatively environmentally-friendly country. A lot of its residents earn money through raising livestock and selling crops. The only problem Cuba has had was the use of illegal pesticides, but the government has recently put forth a lot of effort to solve this problem. Another one of Cuba’s efforts to go green is its implementation of organic products only on all farms. In addition, in recent years, Cuba has put a lot of money into hydroelectricity.

4) China


This one may really come as a surprise, since China usually makes the lists of the dirtiest and/or the most polluted countries. However, China is going green in other ways, and one of them is by investing a lot of money into green technologies. One of these technologies is the smart grid system. The smart grid system involves various digital technologies application to automate and modernize distribution assets and transmission in order to respond to and anticipate system disturbances. The smart grid also provides customers with the ability to control how much energy they use, and it creates a better use of resources. The smart grid is also a key enabler to utilize alternative energy sources like wind and solar power.
