Cleaner energy used to be cheaper than fossil fuels, but that is changing. Every year, renewable energy becomes more economical, and some alternatives are currently cheaper than fossil fuels. Since 2010, the cost of solar has dropped by 89 percent. In most nations, going solar is now cheaper than building new coal power plants, and solar is now the cheapest electricity ever. Despite losses, the renewables sector has showed some resilience in the midst of a very difficult year.
