One of the main obstacles is the inability of aging power grids to not only provide enough energy to keep the world moving but to accept the newer forms of energy being provided.
Stalled spending on electrical grids worldwide is slowing the rollout of renewable energy and could put efforts to limit climate change at risk if millions of miles of power lines are not added or refurbished in the next few years, the International Energy Agency said.
IEA Executive Director Fatih Birol told The Associated Press in an interview that there is a long line of renewable projects waiting for the green light to connect to the grid.
One of the major problems with these newer green energy solutions is that they each have their own unique infrastructure.
If you go put up a bunch of windmills on a hill, hooking them up to the grid isn't as simple as running an extension cord down to the nearest powerlines and plugging them in as if you were setting up a new Playstation in your house.
So by engaging in this sort of widespread conversion, you are taking up more space and producing less energy as a result, even as demands on the grid continue to increase as the population grows.
The reality is that our energy grids around the world were designed and built to run on either fossil fuels or hydroelectric power.
