Final answer:
Diversifying DTE Gas' natural gas supply can be achieved through integrating renewable energy sources, enhancing infrastructure, expanding the use of natural gas in different sectors, and investing in energy efficiency and emerging technologies.
Step-by-step explanation:
To diversify DTE Gas' natural gas supply base, several strategies can be employed. Firstly, incorporating renewable energy sources such as solar, wind, and geothermal can provide increased resiliency and lessen the reliance on a single energy source. In addition, renewable energy brings a multitude of employment opportunities and is a sustainable field. Secondly, it is crucial to develop the infrastructure for additional energy sources, including technological advancements for storage and transportation systems, to improve supply stability. Furthermore, expanding the use of natural gas for electricity production and industrial processes, as well as transportation, via natural gas vehicles, can reduce dependency on oil. Lastly, investing in energy efficiency measures and emerging technologies such as hybrid vehicles, biodiesel, and hydrogen fuel cells contribute to a diverse and sustainable energy base.
