The transition to renewable energy is a complex process that involves various strategies to reduce reliance on fossil fuels. The assertion that natural gas can act as a "bridge energy" for renewables is grounded in its characteristics as a cleaner-burning fossil fuel compared to coal and oil. Natural gas emits less carbon dioxide when burned, which means it can help reduce greenhouse gas emissions during the transition period while renewable energy sources, such as solar and wind, are being developed and scaled up.

Natural gas can serve as a reliable backup for intermittent renewable resources, like solar and wind, which do not produce energy consistently throughout the day or year. This makes it a feasible transitional option that can support the energy grid as it moves toward greater adoption of renewables, facilitating a smoother transition to a low-carbon energy future.

In contrast, the other statements misrepresent the current state of renewable energy transitioning. For example, there are various U.S. states with renewable energy mandates or goals, contrary to the claim about a lack of transition requirements. Additionally, while venture capitalists are indeed investing in renewable energy, stating that they have heavily done so does not encapsulate the entire landscape of renewable energy investment, which includes public funding and corporate investment. Lastly, coal's usage concerning CO2 levels
