Solar dominated renewable energy world possible by 2050, and cheaper

A global energy system – including heat and transport – that is 90 per cent renewables and dominated by solar, is not only possible by 2050 – it will also be cheaper. A 4-year study from Finnish-based LUT University and the German-based Energy Watch Group looked at how to meet the 1.5°C target of the Paris climate treaty, and found that the most effective, quickest and cheapest means was to switch just about everything to electricity, and power it with solar and other renewable energy technologies. “A global transition to 100% renewable energy across all sectors – power, heat, transport, and desalination before 2050 is feasible,” the study concludes. In fact, the authors say, it could be done quicker than that.
