On the backend of a major energy crisis in Texas, many people have been left wondering what went wrong with the power grid.
In Texas, the major source of energy is natural gas followed by coal, gasoline, and several sources of renewable energy including wind power. In last weeks’ case, the bitter cold mixed with freezing precipitation combined to freeze the natural gas lines and wind turbines. By the middle of the week, 46,000 megawatts of energy were unusable; over half of which came from natural gas, coal, and nuclear plants which account for the leading sources of energy for Texas.
So what happened? Why did so many energy resources fail? To start, natural gas pipelines began to see issues with freezing parts causing them to be shut down. With natural gas being limited, the other methods of power were expected to pick up the slack. Wind power was able to produce energy until ice began to form on the wind turbine wings causing them to stop catching wind. Wind turbines can be outfitted to have insulation on the wings to combat freezing and allow them to run in even the arctic...Which would have been great for Texas who was dealing with arctic air. The problem is that many of these ways to combat winter weather’s effects on energy resources are not implemented as Texas normally doesn’t see harsh winter conditions like this.
All forms of energy, renewable and non-renewable, have pitfalls that make them susceptible to different weather conditions. In this case, it was the perfect storm that caused such widespread power issues across the board.
