Solar power, once so costly it made economic sense only in spaceships, is becoming cheap enough that it will push coal and even natural-gas plants out of business faster than previously forecast.
That’s the conclusion of a Bloomberg New Energy Finance outlook for how fuel and electricity markets will evolve by 2040. The research group estimated solar already rivals the cost of new coal power plants in Germany and the U.S. and by 2021 will do so in quick-growing markets such as China and India.
The scenario suggests green energy is taking root more quickly than most experts anticipate. It would mean that global carbon dioxide pollution from fossil fuels may decline after 2026, a contrast with the International Energy Agency’s central forecast, which sees emissions rising steadily for decades to come. “Costs of new energy technologies are falling in a way that it’s more a matter of when than if,” said Seb Henbest, a researcher at BNEF in London and lead author of the report.
The report also found that through 2040:
• China and India represent the biggest markets for new power generation, drawing $4 trillion, or about 39 percent all investment in the industry.
• The cost of offshore wind farms, until recently the most expensive mainstream renewable technology, will slide 71 percent, making turbines based at sea another competitive form of generation.
• At least $239 billion will be invested in lithium-ion batteries, making energy storage devices a practical way to keep homes and power grids supplied efficiently and spreading the use…
