Can Renewable Energy Be More Reliable Than Conventional Power Grids?

Imagine you are sitting in the dark and while you are reading your battery is running low. As I’m writing this, millions of Californians are affected by a power outage. The overland power lines used to transport power are prone to storm damage and can spark wildfires. Stormy weather has been forecasted and utility companies shut off power as a preventive measure to avoid wildfires.

Why do we still use overland power lines? What happened to the energy transformation? What happened to the idea of flexible microgrids?

Microgrids are a set of different renewable energy sources such as wind or solar, combined with energy storage and load management tools. They generate, store and distribute energy. Microgrids can run independently from the traditional power grid and are much more flexible in emergency situations.

Transitioning our electricity from fossil fuels to renewables is an important way to address climate change. According to project drawdown 40 percent of annual greenhouse gas emission come from the power sector. Shifting to renewable power sources will have a big impact on lowering greenhouse gas emissions. So, where are we in the transition to renewable and flexible electricity and what’s this week’s good news?

This week’s story brings us to a warm and sunny place. Picture white sandy beaches and crystal clear water. This story is about the Abaco Islands in the northern Bahamas. Battered from recent hurricane Dorian, most of the power grid has been destroyed. In collaboration with the non-profit Rocky Mountain Institute, the challenge is turned into an opportunity. They plan to install solar powered microgrids to transition the islands to renewable energy sources.

High electricity costs in the Caribbean, volatile global oil prices, and a reliance on imported diesel create a clear business case for clean energy.

Another benefit is the flexibility of microgrids. They are able to bounce back quickly after natural disasters.

What I like most about the planned project is that the Bahamas are becoming a worldwide showcase for solar micro grids. What can California learn from the Bahamas? By replacing fossil fuels with renewables, they are reducing greenhouse gas emissions substantially. Let’s hope they inspire many other countries to follow!
