Solar panel capacity to overtake nuclear energy

-

SOLAR panel capacity is set to overtake nuclear worldwide for the first time within the next few months, according to expert prediction­s.

The total capacity of nuclear power is currently about 391.5 gigawatts, but the total capacity of photovolta­ic cells is expected to hit 390 gigawatts by the end of the year, with demand growing at up to 8% per year, according to GTM Research.

While this would be a landmark moment for renewable energy, nuclear still generates much more electricit­y than solar – nearly 2.5 million gigawatt-hours a year compared to the latter’s 375 000 gigawatt-hours.

Stephen Lacy, writing on GTM’s website, said: “It’s still going to be a record-breaking year for new solar capacity additions, yet again. The 81 gigawatts expected this year are more than double the amount of solar capacity installed in 2014. And it’s 32 times more solar deployed a decade ago. (In the year 2000, global installati­ons totalled 150 megawatts.)

“One of the most telling statistics: By 2022, global capacity will likely reach 871 gigawatts. That’s about 43 gigawatts more than expected cumulative wind installs by that date. And it’s more than double today’s nuclear capacity.”

While solar accounts for about 1.8% of global electricit­y generation at present, the Internatio­nal Energy Agency has predicted this could rise to 16% by 2050 under a “highgrowth scenario”, which would make it the largest source of energy in the world.

Lacy said: “In the last three years, growth rates and cost reductions for solar have far exceeded projection­s. Meanwhile, high costs, slow constructi­on and competitiv­e renewable alternativ­es are causing the global nuclear industry to falter. The trend lines are becoming clearer every year.”

The Sun delivers enough energy to the Earth in an hour to provide humans with everything they need for an entire year. – The Independen­t
