In 2018, onshore wind and solar energy will become the lowest-cost way of generating electricity, making renewables an attractive option for investors. This lower cost means that those with an interest in sustaining our planet are increasingly aligned with those who are driven by profit. As Michael Drexler, agenda adviser to the World Economic Forum, stated in a debate in April 2017: “Solar and wind have just become very competitive and costs continue to fall. It is not only a commercially viable option, but an outright compelling investment opportunity with long-term, stable, inflation-protected returns.”

Anyone who’s a fan of wind or solar power has heard the argument that “the wind doesn’t always blow and the sun doesn’t always shine”. This is called ‘intermittency’ – the idea that you might not get a constant flow of power from a particular source. All energy sources are intermittent (coal plants can trip, pipelines can explode, and nuclear reactors can be invaded by jellyfish), but it’s a particular challenge for renewable energy. Some people think this means we’ll always need lots of giant coal, gas or nuclear power stations (sometimes called ‘baseload’) to keep the lights on. But that’s not really how it works anymore. Luckily, internet commenters weren’t the first to discover weather or night-time, and people have been working on solving intermittency for a while. Thanks to them, we now know that a good mix of renewable energy can do the job, even when the wind’s not blowing. Check out our new video explainer to learn how it works – or keep scrolling for the text version.
