PrintSolar Energy
The sun is far and away the largest potential source of energy to power things on our planet. Humans have been using the sun as an energy source for thousands of years – just think about agriculture and how that would work without sunlight – but the industry of using solar energy to create electricity is in its relative infancy. Growth is fast – in percentage terms, solar is the fastest-growing energy source on the planet. And the cost of solar power, one of its most formidable barriers, is coming down quickly as well. In this module, we’ll take a look at some of the most common technologies used to convert solar energy to electricity.
