Bright future, solar power is the cheapest form of energy in 58 countries



We aren’t at a tipping point yet but the indicators are looking good for the future of renewable power – investment and output are up and costs are down.


According to a new report from some of the world’s leading analyst organisations solar power is becoming the cheapest way to generate electricity.

Data produced by Bloomberg New Energy Finance (BNEF) showed the cost of solar in 58 lower income countries, including China, Brazil and India, had fallen to about a third of levels in 2010 and was now slightly cheaper than wind energy.

In August, an auction to supply electricity in Chile achieved the record low price of $29.10 (£23.30) per megawatt hour, about half the price of a coal competitor.

“Renewables are robustly entering the era of undercutting fossil fuel prices,” said BNEF chairman Michael Liebreich.

Renewable energy is cheap in developing countries that are looking to add more electricity to their national grids.

“Renewable energy will beat any other technology in most of the world without subsidies,” he added.

However, in rich nations where new renewable energy generators must compete with existing fossil fuel power stations the cost of carbon free electricity can be higher.

The dramatic plunge in price had partly been produced by the economies of scale, with China in particular recently adding a vast amount of new solar capacity.

“Solar investment has gone from nothing – literally nothing – like five years ago to quite a lot. A huge part of this story is China, which has been rapidly deploying solar,” said Ethan Zindler, Head of US policy analysis at BNEF.

Beijing has also been helping other countries to pay for solar projects.

A BNEF report, called Climatescope, found China, Chile, Brazil, Uruguay, South Africa, and India were the emerging markets most likely to attract investors in low-carbon energy projects.

Solar power has proved a godsend for remote islands such as Ta’u, part of America Samoa, in the South Pacific. Once reliant on imports of vast amounts of diesel, it is now powered completely by 5,000 solar panels and 60 Tesla batteries. Meanwhile the cost of solar, and other renewables for that matter, are expected to fall even further in coming years as new capacity comes online in Africa and as more countries agree to connect their energy grids together to create a new global energy grid.
