Meanwhile the US is burning as many fossil fuels as possible for the datacenter buildout.

Takeaways:

* The world has reached the 3-terawatt threshold of solar power, with the first terawatt taking 10 years to deploy and the next two terawatts taking less than five years.

* Forecasters expect the world to deploy more than 9 terawatts of solar by 2036, with poor countries' share of solar deployment expected to start growing again from this year onward.

* The main constraint for developing countries to adopt solar power is the lack of accessible financing, and the growth of solar power is also limited by the need for energy storage, such as lithium-ion batteries, to absorb excess power.
