For a long time many people have claimed that stability of power supply and grid costs will be out of control before the United States hits the 20 percent renewable energy percentage. However, Texas has continued to show that renewable energy is reliable and forms the future of energy. Georgetown city located in Texas has become the first city to be fully powered by renewable energy comprising of both solar and wind energy. When we look at Texas at large, 18 percent of the energy being utilized there comes from renewable energy. Although Texas has been the center of oil and gas production for ages, they have demonstrated the will to cut down fossil fuels and embrace green and clean energy. Georgetown has clearly shown that renewable energy saves money for ratepayers. When Georgetown engaged in a wind power investment back in 2014, electricity rates were at 11.4 cents per kilowatt but right now the rates stand only at 8.5 cents per kilowatt.

At 18 percent renewable energy supply, the retail electricity prices in Texas have decreased and they are way below the U.S average. The reason why Texas has achieved this milestone remains the fact that their grid is completely isolated from the United States grids. U.S has three distinct synchronous power grids; Western Interconnection,

Eastern Interconnection, and the Texas Interconnection. All renewable energy generated in Texas is transmitted and at the same time balanced within the state itself. As of December 31st 2017, Texas had approximately 8720 MW of wind energy and 1952MW of solar energy within their interconnection queue. Wind energy forms the biggest share of renewable energy due to its low levelized cost of energy, 3 cents per kilowatt, as compared to utility solar energy which averages 4.5 cents per kilowatt. Texas is still focused at achieving the 20 percent share of renewable energy while avoiding power instability and the spiral costs that critics talk about. Hence, Texas has continued to set an example for the whole of United States when it comes to renewable energy.
