How About New Energy Sources?

Last time, we talked about how the Earth is changing rapidly, mostly because of human behaviors and actions. Yet, it seems that a lot of people on this Earth are making decisions that move the struggle in the wrong direction. Firings are raging, ice is melting, and the human race is not changing. Today, I’m writing about one area that strides are starting to take shape, and hopefully can lead to bigger changes in the future: energy sources.

Climate Change

Now, I won’t hit on every new energy source, but rather on some that interest me and I think could have some real applications in the future of our ever-changing world.

First of all, a new device that is in the works because of some scientists from UCLA and Stanford that seems to be able to create energy from the dark and cold night sky. This device, which does not have an official name yet it seems, uses a thermoelectric generator that produces electricity when one side of the generator is cooler or hotter than the other. In this case of the night sky, the lack of heat it emits along with the device setup using a radiative cooler produces a difference in temperature between the two sides of the generator, thus creating electricity. Although the amount of electricity is little at this time, shaped down to a lightbulb, hopefully with furthering research and developments, technology similar to this device can be included as a renewable source of energy.

An additional source of clean energy that is taking off, specifically in California with plans to grow the infrastructure, is geothermal energy. This clean energy source requires a large plant that naturally taps into heated underground reservoirs to create steam and turn turbines. Although the technology can create renewable electricity around the clock, unlike wind or solar, it has been difficult to implement because of its high costs. As more introspection has been done onto the topic, the overall benefits seem to be outweighing the large cost that were originally holding plans back.

One final technology that may assist in renewable and clean energy in the future is harnessing the kinetic energy of raindrops. A natural occurrence, water droplets produce some force and energy as they travel down to Earth during a storm. A new device, which is really a polymer, called PVDF (polyvinylidene fluoride) seems to hold “piezoelectric” properties, which means that when it undergoes a force or stress (in this case a raindrop), an electric current is produced within the material. Although the amount of energy is small, large storms could produce a decent amount of energy in this manner.

With scientists and others working around the clock to brainstorm and produce new renewable energy sources, the human race has hope it can change its actions in respect to climate change. However, a real effort is going to have to be made.

  1. The clean energy source you listed last reminded me of piezoelectric dance floors that generate energy for the building. I found this really interesting and a couple years back I was researching piezoelectric sensors on the soles of shoes, so there could be potential in charging devices by running or physical activity. Also, you mentioned how the geothermal method was very expensive. Do you think it’s better to make large investments in more effective energy sources that will last?

    1. I think there can be conversations that dive into the benefits to the large investments. Obviously, the human race is going to have to make some big decisions soon in order to solve the beast we created called climate change.

  2. WOW! I am amazed at some of the new technologies that have come out in order to create renewable energy. I’m most surprised by the kinetic energy of raindrops technology. How did someone even think that up? It seems like such an interesting and effective way to make clean energy out of a naturally occurring phenomena. My question is: what happens when it doesn’t rain? How much rain would this device need to capture in order to sustain our communities. It seems like we will need a mixture of all of these clean energy sources in order to make the entire world run on clean energy. Either way, it was super neat to read about clean energy innovations. I’m surprised that I’ve never heard of them before. But, if you hear more news about it during the rest of the semester, I’d love to read another post about it. Great job!

    1. I agree the best way to solve our problem is combining a variety of the new clean energy sources. I’ll try to keep up with the new innovations and see if more can be done for their implementation!
