Within five years, one quarter of all the world's energy will be generated by renewable sources.

That's the finding of a new report from the International Energy Agency, and it's being hailed as “a remarkable shift in a very limited period of time.”

In 2014 alone, almost half of all the new power capacity came from clean energy sources like wind and solar. And, in developed nations, renewables account for nearly all of the new additions to power capacity.

That fact on its own is pretty astounding. And, it's enough to prove that making the switch to all-renewable energy is actually possible, regardless of what we hear from the fossil fuel industry.

According to this new report, “Even in a lower fossil fuel price environment, the policy drivers for renewable electricity – energy diversification, local pollution, and decarbonization aims, remain robust.”

In other words, even where oil, gas, and coal may be cheaper, there are other factors that drive the demand for clean energy.

Although Republican lawmakers often point to major polluters like China and India as a an excuse to avoid acting on climate change, it is actually those same countries that are leading the world in the expansion of renewable energy sources.

While we continue to elect people who refuse to admit that global warming is real, the rest of the world is doing something to address the climate crisis.

Faith Birol, Executive Director of the IEA, said, “Renewables are poised to seize the crucial top spot in global power supply growth, but this is hardly the time for complacency.” She added, “Governments must remove the question marks over renewables if these technologies are to achieve their full potential, and put our energy system on a more secure, sustainable path.”

This report makes it very clear that going to 100 percent clean, renewable energy is possible. The only question left is whether we have the will to fight for an all-renewable future.
