Will Bernie Sanders' Energy Policies Actually Lessen Climate Change?
The short answer is that they are likely to increase emissions in the short term, primarily due to a focus on transitioning from fossil fuels to renewable energy sources. However, a coherent strategy can be effective in the long run.
Strategic Approach to Energy Policy
Wind and Solar Power
The primary strategy involves building extensive wind and solar farms. This is the 'heavy lifting' in the transition away from coal, which is both cheap, easy, and fast to implement. The combination of wind and solar can significantly reduce reliance on coal.
Grid Interconnections
Establishing more grid interconnections will allow for better distribution of electricity, ensuring that energy generated in one area can be efficiently used where it is needed. This could significantly enhance the reliability and efficiency of the energy grid.
Hydroelectric Power from Neighboring Countries
Bilateral contracts with Canada (British Columbia, Quebec, and Manitoba) to purchase carbon-neutral hydroelectric power can complement the renewable energy sources. Hydroelectric power is a reliable and zero-emission energy source, making it a crucial component of a sustainable energy strategy.
Nuclear Power
Leaving existing nuclear plants alone and refurbishing them when necessary makes economic sense. Building new nuclear plants is unlikely, primarily due to cost and time considerations. Maintaining the existing fleet ensures a stable supply of energy while minimizing emissions.
Phasing Out Methane Gas
Methane gas generation should be minimized for peak power and storage needs. The goal should be to phase it out over the next 20-40 years, alongside the use of renewable energy sources. Methane gas, though less prevalent than coal or gas, still contributes significantly to CO2 emissions.
Other Renewable Energy Sources
In addition to wind, solar, and hydroelectric power, consider other potential renewable sources like geothermal and biomass. Geothermal district cooling beside shores and biomass can provide localized renewable energy solutions. These can be particularly useful in urban areas where thermal management is critical.
Maximizing Renewable Energy
Maximizing renewables, as recommended by Bernie Sanders, is a rational choice. In 2015, 115 GW of renewable energy were installed at excellent prices, underscoring the economic viability of renewables. In most markets now, renewables are the most economical form of new energy generation, with CO2 emissions significantly lower than those from gas and coal.
No CO2-Related Policies Can Drastically Affect Climate
It's important to note that CO2-related policies cannot significantly impact climate change on their own. CO2 does not drive climate; it is a greenhouse gas that traps heat and contributes to warming, but climate change is driven by a multitude of factors, including ocean currents, solar radiation, and atmospheric processes.
