Cuba has set a solar power world record as it made a major stride in its renewable energy drive, and it’s a huge moment for the country’s energy future.
The Caribbean island has just smashed through a major milestone, generating a staggering 900MW of solar power in a single day.
That record came just one day after it had already broken the 800MW mark, showing just how fast things are moving.
And with help from China, Cuba is now rapidly transforming how it powers the nation, and what energy sources it relies on.

Cuba sets a solar power world record as renewable energy surges
This wasn’t just a one-off tech spike; it’s part of a much bigger shift.
Cuba has been investing heavily in solar, and the results are already showing in a big way, which makes sense considering how sunny it is there.
In just a year, solar’s share of the country’s electricity jumped from just under six percent to around 20 percent.
That’s a massive leap, especially for a country that has long relied on imported fossil fuels to keep the lights on.
Now, solar farms are popping up across the island, helping to generate huge amounts of power during the day.
The plan is only getting bigger, too, as Cuba is aiming to build dozens of solar parks over the next few years, which could completely reshape its energy mix.

They are getting help from China
A big part of this rapid progress comes down to China’s involvement.
China has been supplying equipment, funding, and expertise to help Cuba roll out solar infrastructure at speed for lots of reasons.
That includes everything from large-scale solar parks to small home systems that can power everyday essentials like fridges and TVs, making the country less reliant on the national grid and foreign oil supplies.
Thousands of these standalone solar kits have already been installed, bringing electricity to places that were previously off the grid.
There is still a challenge, though; solar only works when the sun is out, and Cuba’s peak energy demand happens in the evening, so battery storage is the next big hurdle.
Even so, hitting 900MW is a huge milestone, and it shows just how quickly a country can pivot when it commits to renewable energy.
