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.
Why Wind Turbines Can Provide Resiliency During Cold Waves
“How can wind turbines be useful for communities during extra cold times?”
During times of cold waves, traditional energy generation potential goes down. But this usually coincides with an increase of wind, which heightens the energy potential for wind turbines. This is Why Wind Turbines Can Provide Resiliency During Cold Waves.
The Environmental Impacts of Open-Pit Mining
“What are the environmental impacts of open-pit mining?”
Materials such as rare-earth minerals are often obtained through open-pit mining. However, this process is extremely environmentally destructive, releasing a multitude of harmful chemicals, debris, and dust into the air. The residue can also cause Sound pollution from the machinery, ground vibration from the operations, forcibly resettle people, pollute nearby water and destroy soil fertility. Thus, The Environmental Impacts of Open-Pit Mining must be minimized at all costs!
The Environmental Impacts of Mining Rare Earth Minerals
“What is the pollutive side of renewable energy?”
Rare Earth Minerals are critical for the proliferation of clean energy technologies. However, their extraction methods can be quite toxic to the environment. Since most of these minerals are unearthed using open-pit mining, radionuclides, rare earth elements, and dust and metal are released to the surrounding area, desecrating local life. Because of The Environmental Impacts of Mining Rare Earth Minerals, we need to look into making this process more sustainable to ensure a completely green future for the world.

A Simple Reason Why Humanity Needs to be Less Wasteful to Curb Climate Catastrophe
“What is one tough thing humanity needs to adopt to fight climate change?”
Right now humanity is on track to shoot past a rise of 2-degree centigrade from pre-industrialization by 2030. And one of the primary reasons behind this is because human energy consumption and population has been rising over the years. Much of the global focus to fight this has been increasing technological energy efficiency. But according to the equation I = PAT, if population and affluence rise then it would offset more efficient technology. If humanity does not want to quickly decrease its population then it must change its culture of affluence. This is A Simple Reason Why Humanity Needs to be Less Wasteful to Curb Climate Catastrophe.
I = PAT
“How can we represent environmental impact based on resource consumption?”
Every society has an environmental impact. But since each society has different levels of resource consumption and utilization, each one is different. So how can we quantify this? Well, we can measure impact based on the average of the amount used multiplied by its energy efficiency and the total population. This is known as the I = PAT equation where I is the Environmental Impact P is the Total Population A is the Level of Affluence (how many resources are used) and T is the Technological Efficiency.
The Circular Economy
“How do we need to rethink our approach to consumption?”
Widespread industrialization has lead economically developed societies to think of products of having a finite linear lifespan. However, with the advent of climate change, this needs to change drastically. Instead, manufactured products will need to be recycled and reutilized in a Circular Economy. This will ensure maximum resource utilization and minimize carbon emissions.
