Why HVDC Can Hurt Fire Resilience

“Why are the most serious drawbacks to HVDC lines?”

 

HVDC lines are one of the hottest topics in the renewable energy world nowadays. Their ability to transmit a large volume of electricity across great distances with minuscule losses can make them a vital part of easing the duck curve. However, their high voltage also means that if they get sapped, they have a much higher potential to produce a fire. This will have great implications for the regionalization of California, where increased connectivity to other states could bring grid stability but exacerbate the potential for chaos.

“How can you offset your carbon emissions without changing your own operations?”

 

Some things are extraordinarily difficult to decarbonize. Whether it be air travel or going 100% renewable when the grid itself is based 100% off carbon-emitting resources. But a workaround can be found through Carbon Offsetting. This involves making a purchase of renewable energy or planting a tree that offsets the amount of carbon used. This can be useful for designing policies around technologies whose emissions-free alternatives are still too nascent for commercial use.

“How is Heat Transfer Used to Model Climate Change?”

 

Heat Transfer is one of the foundational course for a Mechanical Engineer. But internal combustion engines and HVAC are not the only things that the theory can be applied to. Climate Scientists will use many of the same Heat Transfer equations when designing climate models. In this way, Heat Transfer is Used to Model Climate Change.

“How can we verify climate change models?”

 

Climate models are extremely useful for helping us predict the impacts of climate change. But how can we verify them? Well, what if we were to map their mathematical functions to historical data and see if they accurately predict temperature rises? If it turns out to be correct, then the model has a good chance of being valid. This Climate Model Verification, often known as hindcasting, gives our methods validity for future policy work.

“How can an economy not contribute to climate change?”

 

Traditionally, economies have grown in tandem with carbon emissions. But with the advent of modern-day extreme climate change this is no longer feasible. To solve this, nations will have to adopt Carbon Neutral Economies in which all sectors have slashed their emissions to zero. The transition to a low carbon economy could yield enormous economic growth as well as inequality easing. Multiple governments around the world are committed to this action, with California’s 2045 and the EU’s 2050 initiatives as examples.

Why the Increasing Frequency of Fires Will Threat Energy Resilience

“How will the increased frequency of fires make us less energy resilient?”

 

The climate is changing. As temperatures get higher, the natural world is being thrown out of balance, and this includes dangerous fires such the one seen in Northern California. As these fires become more frequent, they will threaten power lines and energy generation sources. As a result, The Increasing Frequency of Fires Will Threat Energy Resilience.

“How will Transportation Infrastructure be harmed by more extreme coldwaves?”

 

Transportation infrastructure will definitely be impacted by the changing weather. But climate change is doing much more than rising temperatures. More extreme coldwaves in certain parts of the earth are resulting from changing polar vortex. The behemoth damage brought onto transportation systems includes more delays in train/plane schedules, heavier icing of streets, and more stress on structures. This is How More Extreme Coldwaves will Harm Transportation Infrastructure.
