How Will We Get Energy in the Future?

 How Will We Get Energy in the Future? 

The future: it's hard to imagine, but inevitably, it will come. One of our current challenges is providing energy for a growing population. In 2020, the majority of our energy comes from burning fossil fuels, but we now understand the harm it could cause if we continue to do that. We are consuming energy faster than it can replenish, and even if there were an unlimited supply of fossil fuels, burning them has some nasty side effects. In this post, we will discuss likely scenarios for how our species will use energy in the near future, and then explore possibilities of how we could get our energy thousands of years from now.

The near future 

What I'm about to say has been stressed enough times on this blog, and if you know anything about energy, you probably have heard this too: we must stop relying on fossil fuels for energy. In the next few years, we will have to begin the transition to clean and renewable sources. Renewable energy will never run out, and it has a minimal effect on eco-systems. If we can power the planet by entirely using the energy of wind, water, and the sun, we will be able to use more energy without worsening climate change. EarthPlex has an entire post about renewable energy that you can read by clicking here.

When I think about the future, I see metropolises with giant skyscrapers and beaming lights. I think of Coruscant from Star Wars, and I imagine the architecture of Star Trek movies; what these visions have in common is a source of power to support the people's energy consumption. Renewable energy is our next step to arrive at that future.

The distant future 

One day, humans may outgrow Earth and colonize other planets and celestial bodies. Eventually, solar panels and windmills may not make the cut, so what could power a hyper-advanced economy?

This post was partially inspired by Year Million, a docuseries that explores how advanced our species could be in the distant future. This concept was briefly brought up in the episode about space travel, where the host explained the far-out concept of a Dyson sphere. He said that we could build a structure around the sun to absorb its energy. However, we don't have enough materials on earth to wrap around an entire star, so we'd have to mine objects in space - such as asteroids - and use the materials from them to create an edifice that could absorb all of the sun's energy. We are probably millennia from this becoming a reality, but it's fascinating to speculate. 

However we do get our energy thousands of years from now, it will be in ways almost unthinkable to ancient twenty-first-century folks. If you're reading this in the distant future, am I famous? Time will tell how accurate these predictions are, but as I've seen in articles of people from the 1800s trying to predict the future, it's hard to get right.

Climate Change - The Basics

Climate Change - The Basics
Definition:We are in a climate crisis, but what does that mean?Like we did when exploring the meaning of eco-friendly, we're going to dissect the word. Climate is the weather in an area over an extended period of time.
Climate change is when long-term weather patterns shift, hence climate change. Temperatures gradually rise, which could, and has begun to, cause great destruction.
Effects:Climate change, sometimes referred to as global warming, has destroyed ecosystems. According to the World Wildlife Fund, “Populations of mammals, birds, fish, reptiles, and amphibians have, on average, declined by 60% between 1970 and 2014, the most recent year with available data.” Fewer species roam the wild because of mankind’s actions, and the people who cause it pay the smallest price.NASA has observed the effects of climate change from space. They have seen rising sea levels, wildfires, melting ice caps, and a whole lot more. Earth is changing rapidly, but what exact…

Double Trouble: The Fujiwhara Effect

Double Trouble: The Fujiwhara Effect By Mahir Hossain, age 14
Hurricanes. A spiral of destruction with catastrophic winds, heavy downpour, and lightning strikes that can split cable lines and trees in half. Many have experienced the damaging effects of hurricanes in Latin America and the Southern United States, but what if there were two spirals of destruction, or worse, what if they were to collide? The rare phenomenon has already materialized in Louisiana and Texas amongst other states who encountered the storm’s wrath. So exactly how does the Fujiwhara effect work? 
The phenomenon is named after Sakuhei Fujiwhara, a Japanese meteorologist who was highly encapsulated with works of vortices, rotation, and other factors that contributed to such natural disasters. Although he put most of his time into the development of hurricane research, his findings of double vortices while studying at the Meteorological College of Japan was very intriguing to other meteorologists who tried to compreh…

Beyond Meat and the Environment

Beyond Meat and the EnvironmentBurgers are a staple of the American diet. Billions of them are consumed each year. Sadly, meat production requires energy, water, and land. Agriculture, especially with cattle, is really bad for the Earth. We all love burgers, but we don’t want to feel guilty eating them. That’s where Beyond Meat comes in. Beyond believes that “there is a better way to feed the planet.” So, do they have a better way to feed the planet? Well, yes, depending on what you consider better. At EarthPlex, we consider the better option to be the one that is more sustainable. You may be wondering, What is my Big Mac doing to destroy the world? Well, Brian, red meat uses a lot of water in the production process, requires farming land, and methane from cattle digestion pumps tons of carbon dioxide into the atmosphere. Now you may be wondering, How can one company fix all of these problems? Well - let’s  make you Jill - Beyond doesn’t make meat like most companies do; instead, they…

The Environmental Impact of Phineas and Ferb's Creations

‌The Environmental Impact of Phineas and Ferb's CreationsI saw the trailer for Phineas and Ferb: Candace Against the Universe about a week ago, and I'm so excited to watch it. Unfortunately, it's only available on Disney Plus, so I'll either subscribe or use the free trial. The trailer got me thinking about my childhood obsession with Phineas and Ferb. Then I wondered, how do they have the resources to build all of these things?, and do they reuse the materials, or do Dr. Doofenshmirtz's inators cause them to buy new stuff every time Phineas says, "Ferb, I know what we're going to do today!"

I decided to analyze the environmental impacts of what Phineas and Ferb have built during their 104 days of summer vacation. Before I go into the basics of their carbon footprint, there are two things I must get out of the way. First, this is only a TV show, and we will look into what Phineas and Ferb have built; we will not analyze the impact of producing a televi…

What Does Eco-Friendly Really Mean?

What Does Eco-Friendly Really Mean? Definition: You hear it all the time, but what on Earth does eco-friendly mean? Well, Earth... friendly or not harmful to Earth. To understand the definition of this word and what eco-friendly products are, we have to dissect the word. Eco is a prefix that means Earth and the environment (e.g. ecosystem). And if you don’t know the meaning of friendly, perhaps you’re in the wrong place. Eco-friendly goods and services claim that they do not hurt our planet.Examples:For example, biodegradable containers help our planet and have a plethora of advantages over the containers most of us currently use. Those containers are eco-friendly because using them benefits the planet. Another common example of eco-friendly equipment is solar panels. Unlike fossil fuels, they do not output harmful gas into the atmosphere. By maintaining Earth’s natural resources, solar panels are considered to be eco-friendly.Similar Words:Words often used in the place of eco-friendl…
