This is a question that has been debated by scientists for years. The answer, of course, depends on a number of factors, including the efficiency of renewable energy sources and the amount of land available for solar panels and wind turbines.
A recent study published in the journal Nature found that if the world switched to renewable energy, it could sustain a population of 10 billion people – about 1.5 billion more than the current population. The study’s authors used a computer model to simulate the impact of different energy scenarios on the planet’s resources.
In the study, the world’s population was assumed to grow to 10 billion by 2100. The researchers then looked at how different energy sources would impact the planet’s ability to sustain this population. They found that a switch to renewable energy would be necessary to sustain a population of 10 billion.
The study’s authors say that the world would need to generate about twice as much energy from renewable sources as it does today. They estimate that, in a world powered by renewable energy, solar panels would cover an area the size of Spain and wind turbines would cover an area the size of Australia.
While this may sound like a lot of land, the researchers say that it’s actually a small price to pay for the benefits of renewable energy. They say that renewable energy is much cleaner than fossil fuels and would help to reduce the amount of greenhouse gases in the atmosphere.
The study’s authors say that their findings show that the world can sustain a much larger population than it does today – but only if we make the switch to renewable energy.

Q: What is the max population the Earth can sustain?
A: There is no definitive answer to this question as it depends on a number of factors, including technological advances, resource availability, and environmental conditions. However, some estimates suggest that the Earth could potentially support a population of up to 10 billion people.
Q: Can the world go 100% renewable?
A: It is possible for the world to go 100% renewable, but it would be a huge undertaking. There are many factors to consider, including the cost of transitioning to renewable energy, the impact on the environment, and the availability of resources. It would be a challenge, but it is possible.
Q: Can the world survive on renewable energy?
A: There is no definitive answer to this question as it depends on a number of factors, including the amount of renewable energy resources available and the efficiency of renewable energy technologies. Some experts believe that the world could transition to 100% renewable energy, while others are more skeptical. However, many countries are already making significant progress in transitioning to renewable energy, so it is certainly possible that the world could eventually rely entirely on renewable energy sources.
