We're starting to emerge from an energy crisis, which showed the very volatile nature of an energy system based on fossil fuels.  

One piece of good news to come from this crisis was countries across the world making major investments in renewable energy.  A report from the IEA  has found that renewable generation is planned to account for more than 90% of electricity expansion across the world over the next five years, and this planned increase in renewable capacity is more than was built in the past 20 years. This massive expansion is 30% higher than was predicted before the crisis.  

What's more, renewables are finally set to overtake coal as the world's biggest source of power by early 2025.
