“Every hour the sun beams onto Earth more than enough energy to satisfy global energy needs for an entire year.”
Light and energy from the sun allows for the very existence of all animal and plant life. It is also the pillar of one of our most exciting power energy sources.
The earth receives about 1,366 watts of direct solar radiation per square meter; it has been estimated that the total surface area required to power the world with solar energy is only around 366,375 square kilometers. Despite the abundance of viable energy coming from above us, solar energy production currently only accounts for less than one tenth of one percent globally.
A major industry report by Clean Energy Group and SmartPower indicated that four primary barriers were slowing the widespread adoption of solar energy: cost, complexity, misinformation, and inertia. Luckily, the components of these blockages are becoming increasingly diluted with the expansion of the industry and its supporters. Four years later experts are expecting the solar industry to grow 20-40% per year for the next 10 years, as more private homes and businesses discover the practicality and immensity of this exciting energy resource and governments continue to encourage the switch to solar with energy credits and solar ROIs.
Solar energy is an essential means of energy production as it is fully natural and without the negative environmental impacts of other sources such as coal—upon which we are still largely dependent. With dwindling fossil fuel resources and climate change looming in our not-so-distant futures, it is more important than ever to realize the importance of harnessing more ethical means of energy generation.
