One weird trick to stop climate change

Ending fossil fuel dependence is the single most impactful thing we can do

Learning about clean energy can radicalize a person.

You realize pretty quickly that everything we need to stop climate change—not just to lessen the impacts, but to fully reverse course—already exists. The technology is mature.

Fossil fuels are directly responsible for 80% of all greenhouse gas emissions. We can replace them with cheap, efficient, resilient, renewable energy. Solar, wind, and batteries, plus emerging technologies like enhanced geothermal engineering and pumped hydro.
Upon completing the clean energy transition, the cost of electricity will continually fall until it reaches near-zero cost. That will mean effectively free power for everyone on earth.
So much of what's expensive in our world comes down to the cost of its energy input. So when energy becomes effectively free, the world gets very cheap. Transportation, heating and cooling, growing food, desalinating water, sucking carbon dioxide out of the air—all of these will cost us almost nothing.
In a world where electricity is free and everything is electrified, humans won't fight wars over resources. We can use our lives to pursue scientific advances, to make art, and to serve as the stewards of this incredible planet.

Sounds good, right? All that's missing is the political will to make it happen. Too many of our politicians—Republicans and Democrats—are owned by fossil fuel companies and the investor-owned utilities who'd rather watch the world burn to ashes than reduce their profit margin by even a single percent.

That's why I'm fighting for the world I want to inhabit:

Public ownership of our energy system
Nationalizing fossil fuel companies
Investment in climate adaptation

I can't do it alone. We need a mass movement of knowledgeable, dedicated eco-socialists hellbent on making it happen. That's what the NYC-DSA Ecosocialists are building here in New York City. If you're in New York, I hope you'll join us. If you're not, join your local chapter of DSA and start your own Ecosocialist Working Group.

Here on Green Juice, we're making tricky topics easy for anyone to understand. Because the more you learn, the stronger you'll believe in this beautiful, clean, renewable world, and more convincing you'll become in your own activism.

We've written over 50 articles about clean energy tech, utilities, climate, more.

Here are some good places to start:

1. How to solve the energy crisis

2. Clean energy metrics are confusing. This primer makes it make sense.

3. The insane way utilities make a profit—and why it's killing us

4. Our top-down energy system no longer makes sense, and it's causing a full-blown crisis

5. What is eco-socialism, and how is it different from other climate movements?

If you've read all those and are hungry for more, I recommend clicking on whatever looks most interesting. Here are some more topics we've written about:
