Living Off the Grid in 2050
by: Annalene A. dela Cruz
The solar industry has seen phenomenal growth over the last 50 years. According to an article that Fortune published in September 2014, “Solar power could be world’s main energy source by 2050.” This actually is not too far-fetched. Among the roster of pressing issues the world faces today, climate change is arguably at the top of the list. Consumption of non-renewable resources like oil, gas, and coal is increasing at an alarming rate. The use of these resources have brought devastating changes on our environment, and this has pushed mankind to seek for clean alternative solutions.
Solar energy continues to develop globally, as it promises clean green electricity powered by the heat of the sun. It is a renewable, free, and inexhaustible source of energy, which is non-polluting. While the first exploration on solar power dates back to 7th Century B.C., it was not fully developed until the 1950’s when Photovoltaic technology was born. However, despite the promise of renewable electricity, it did not pick up popularity right away as the technology involved is capital intensive.
In recent years, we have seen a rapid improvement in technology which rendered solar panels to be more cost efficient. Nowadays, we see a growing number of households turning to solar energy as their main power source. We hear of large scale solar projects, like solar power stations being built in different parts of the world. In the United States alone, the solar industry achieved a 34% growth in 2014, with nearly 645,000 homes and businesses switching to solar power.
With these developments, it is clear that the world is seriously pushing the advancement of solar technology. As sure as the sun rises, solar power will be able to sustain not only households and businesses, but also an entire nation with a huge energy demand.
