Solar could be the world’s largest source of energy by 2050
It’s doubling every 2 years and has been for 20 years.
So how far away is solar from meeting 100% of the world’s energy needs? Eight doublings, says Ray Kurzweil, which will take just 16 years. And supply is not an issue either, he adds: “After we double eight more times and we’re meeting all of the world’s energy needs through solar, we’ll be using 1 part in 10,000 of the sunlight that falls on the earth.
Plummeting costs in the solar industry is driving down energy prices and making solar as competitive as coal
Case in point, the reduced costs related to the construction of solar powered technologies could allow the Chinese government to slash the prices that are offered to photovoltaic developers by more than a third by 2020. Ultimately, this would mean that plants powered by the Sun would be competitive with coal by the decade’s close.
Solar energy has been on the rise, and based on new data from GTM Research, it could rival nuclear energy in terms of global capacity by the end of 2017.
Solar energy can help us reduce our reliance on fossil fuels, which we desperately need to do as our net emission of 37 gigatonnes of CO₂ per year are wreaking havoc on the planet, causing global warming, extreme weather events, and millions of deaths.
Every hour the sun beams onto Earth more than enough energy to satisfy global energy needs for an entire year.
Since its discovery, harnessing solar energy efficiently has been the subject of researches for many years. But one thing about solar energy collection is that it’s only available during the day—until now.
