For enough solar power to power the entire world’s energy consumption, we would only need an area the size of Spain!
In order to power everyone's energy consumption purely with solar power alone, a recent study found that we would only need an area the size of Spain.
Saying this, however, there are a number of caveats in the study. Most noticeable is that they assumed year-round sunshine, 24 hours a day 7 days a week. Obviously, this is not something that generally occurs on Earth. Moreover, solar power is currently too inefficient to be monetarily practical on such a large scale.
However, I do like this study as it does show that switching entirely to renewable sources of energy is not necessarily as difficult as it may seem. Research into renewable technologies does need a lot more funding before they become a commercially viable option both for big companies and the average person - e.g. to increase their efficiency; reduce the costs. However, it is possible that one day renewables will become our main energy sources - potentially even our only energy source!
Additionally, while the area of Spain may seem a huge amount of land (500,000km squared), this area is just over a tenth of what the USA currently devotes to agriculture!

What is the RET scheme?
The Renewable Energy Target (RET) scheme is a government initiative to ensure that 20% of Australia’s electricity will come from renewable sources by 2020. The RET scheme encourages more people to help the environment by installing solar panels and helps communities with the installation costs. Under the scheme, funds are issued in the form of Small Technology Certificates (STCs) to the property owner, reducing their financial costs.
