Cuba has rapidly transitioned to solar and wind power with assistance from China, increasing solar energy generation to over 20 percent in just 12 months to address US sanctions cutting off oil supply from Venezuela. The country aims to achieve energy independence by 2028 with up to 600 megawatts of battery storage, rendering the US oil blockade economically irrelevant. This transition showcases one of the fastest energy transitions achieved by a developing nation and could serve as a model for other countries facing energy crises. The conflict in the Middle East has also led to an increase in interest in personal renewable energy solutions, such as solar installations, home batteries, and EV chargers, signaling a potential tipping point for the world to embrace renewables.
