Colorado has a goal to achieve a zero-carbon electricity grid by 2040 and reduce greenhouse gas emissions from other sectors such as transportation through increased use of renewable fuels like biomethane.

These are just a few examples, as more states are adopting similar goals and targets for increasing the use of renewable gases in their energy mix over the coming decades.

18. Are there concerns about potential methane emissions from increased use of biogas or landfill gas projects in Minnesota?

Yes, there are concerns about potential methane emissions from increased use of biogas or landfill gas projects in Minnesota. Methane is a potent greenhouse gas, with a much higher global warming potential than carbon dioxide. The release of methane into the atmosphere from these projects could contribute to climate change.

In addition, if these projects are not properly managed and maintained, they can also lead to localized air pollution and odour issues. Proper siting and monitoring of these projects is important to mitigate any potential negative impacts on nearby communities.

There are also concerns about the impact on local ecosystems, as well as the potential contamination of groundwater and surface water through leachate from landfills. Careful planning and management of biogas and landfill gas projects is necessary to minimize these risks.

Furthermore, there have been concerns raised about the displacement of other renewable energy sources, such as wind and solar power, by incentivizing the use of biogas or landfill gas. This could result in an overall increase in greenhouse gas emissions if renewable energy development is slowed down due to a focus on biogas or landfill gas.

Overall, while biogas and landfill gas can be valuable sources of renewable energy, it is important that their implementation is carefully planned and monitored to avoid negative impacts on the environment and local communities.

19 .What role do renewables play, compared to other sources, when it comes to grid reliability and price stability?

Renewable energy sources, such as wind and solar power, play an increasingly important role in the overall energy mix and are becoming significant contributors to grid reliability and price stability. This is due to several reasons:

1. Decreasing Costs: The cost of renewable energy technologies has been decreasing significantly in recent years, making them more competitive with traditional sources of electricity such as coal and natural gas. This means that renewables can now provide a reliable and inexpensive source of energy.

2. Diversification: By diversifying the sources of electricity generation, renewables reduce the risk of disruptions to the grid caused by unexpected events like equipment failures or severe weather conditions. This makes the grid more resilient and less susceptible to price spikes.

3. No Fuel Cost: Unlike fossil fuels, renewable energy sources have no fuel cost since they use naturally occurring resources such as sunlight and wind. This eliminates the risk of volatile fuel prices impacting electricity costs.

4. Inherent Stability: Many renewable energy technologies, such as hydropower and geothermal power, provide a stable base load supply that can help balance out fluctuations from other sources like wind and solar power. This helps to maintain stable prices for electricity consumers.

5. Localized Generation: Renewable energy systems can be installed closer to where the electricity is needed, reducing transmission losses and increasing overall efficiency of the grid. This also improves resilience by reducing reliance on long-distance transmission lines that can be affected by extreme weather events.

Overall, renewables offer numerous benefits when it comes to grid reliability and price stability compared to traditional sources. As technology continues to advance and costs continue to decrease, we can expect renewables to play an even larger role in meeting our energy needs while maintaining a stable grid.
