“Why are quantum dots for solar panels so useful?”

 

Quantum dots are bringing a revolution into the world of semiconductors. And since semiconductors are the backbones of solar panels, things will be greatly changed for them as well. The extra emissivity offered by quantum dots means that two and possibly three electrons can be generated for every photon received, vastly increasing its potential! Quantum dot solar panels can achieve as much as 65% efficiency, nearly double of the theoretical limit of normal panels. This is why Quantum Dots for Solar Panels are so exciting.

“How can renewable energy be used in unusable land?”

 

Brownfields, or areas where pollution has made habitation unfit for humans, are often thought as unusable. However, since renewable energy is often immune to a lot of the toxins present in these areas, they have no problem being installed there. As a result Renewable Energy in Brownfields can open up a lot of sustainability potential in blighted areas.

How can community-sourced energy be cheaper and greener?

 

There is a revolution brewing in the renewable energy world. While in the past residents and businesses were tied to one electric utility based on their geographic area, organizations known as Community Choice Aggregators are starting to sprout up and challenge this. Community choice aggregators or CCAs are non-profit organizations that procure power generation and deliver it to customers through a utility’s transmission lines. Since these do not operate for investors and only need to pay for energy and staff, they can give their customers better rates than traditional electricity service and focus on particular resources. To illustrate, just look at the CCA San Jose Clean Energy. Even though their energy portfolio is 45% Renewable Energy/80% carbon-free, they sell energy at rates 1% lower than the standard San Francisco Bay Area PG&E service which is 33% Renewable Energy/78% carbon-free. This is How Community Choice Aggregators Can Offer Cleaner Energy at Lower Rates!

“Why are certain minerals so important for renewable energy?”

 

Renewable energy is one of the fastest growing technologies in the world. But like every manufactured product, they are heavily dependent on the minerals that compose them. One of the most important amongst these are Rare Earth Minerals. Rare Earth Minerals such as neodymium, terbium, indium, dysprosium, and praseodymium form vital components for solar panels, wind turbine motors, batteries, and electric vehicles. With such constricted supplies in the world, geopolitics will shift to favor countries with large amounts of these resources, underlying The Importance of Rare Earth Minerals to Renewable Energy.

“How would the Navajo Nation benefit from the addition of solar energy?”

 

The Navajo is an indigenous tribe located roughly in Northeastern Arizona and Northwestern New Mexico, right on top of some of the greatest solar resources in the world. If the Navajo were to install utility-scale solar energy and send it to nearby communities for profit, they would reap great benefits.

“How does silicon wiring harm solar PV Cells?”

 

Silicon wiring is needed for the electrons produced in solar PV cells to move around. However, the wires on the front of the solar cells cover 5-10% of the surface and reflect incoming light, thereby lowering the efficiency. As a result, there are many Problems with Silicon Wiring in Solar PV Cells.

How Microgrids will Help Rural and Remote Communities

“How will Microgrids be useful for rural and isolated communities?”

 

Traditional power transmission infrastructure is not beneficial for rural and remote communities. Long power lines from centralized generation sources are prone to failure and are expensive to maintain. Plus, due to their limited lifespan, they will have to be replaced which can greatly drive up costs!

To solve this, we need to completely rethink how we transmit electricity. One possible solution is to implement microgrids with distributed energy resources. This will take away the need for complicated transmission, and can enable grid independence. This is How Microgrids will Help Rural and Remote Communities.
