Our Energy Future: Solar Power

In 2007, the Discovery Channel aired a three-part special called 2057 , in which futurists and scientists theorized about how life would change and improve over the next 50 years.

One of the parts of the special, titled 2057: The World, explored how humanity would obtain energy to fuel our civilization. The episode followed a fictitious story line where astronauts aboard a space station were trying to develop solar panels that were much more efficient than today’s panels.

Modern solar panels are only 14-18% efficient because the material (silicon) used only absorbs a fraction of the power of sunlight. Current prototypes in developement are expected to raise the efficiency to nearly 40%. However, to compete with the power derived from fossil fuels, solar power efficiency has to be at least 50%.

Thankfully, in the Netherlands, scientists are working on creating an entirely new, super-efficient material for solar power. The promise: 80% efficiency. Say goodbye to the old days of dirty oil and coal.

Here’s a clip of the episode.
