Quotes about Sustainability

Solar cells, for example, got almost 10 times cheaper between 2010 and 2020, and the price of a full solar system went down by 11 percent in 2019 alone.

The most effective tree-related strategy for climate change is to stop cutting down so many of the trees we already have.

The Green Premiums answer these questions, measuring the cost of getting to zero, sector by sector, and highlighting where we need to innovate

The reason the world emits so much greenhouse gas is that—as long as you ignore the long-term damage they do—our current energy technologies are by and large the cheapest ones available. So moving our immense energy economy from "dirty," carbon-emitting technologies to ones with zero emissions will cost something.

fission, carbon capture and sequestration, offshore wind, cellulosic ethanol (a type of advanced biofuel), and meat alternatives.

In Indonesia, on the other hand, forests are being cut down to make way for palm trees, which provide the palm oil you'll find in everything from movie-theater popcorn to shampoo. It's one of the main reasons why the country is the world's fourth-largest emitter of greenhouse gases.

We already know the emissions number; it's 51 billion tons each year. As for the cost of removing a ton of carbon from the air, that figure hasn't been firmly established, but it's at least $200 per ton. With some innovation, I think we can realistically expect it to get down to $100 per ton, so that's the number I'll use. That gives us the following equation: 51 billion tons per year x $100 per ton = $5.1 trillion per year

With all the additional electricity we'll be using, and assuming that wind and solar play a significant role, completely decarbonizing America's power grid by 2050 will require adding around 75 gigawatts of capacity every year for the next 30 years.

The world needs to provide more energy so the poorest can thrive, but we need to provide that energy without releasing any more greenhouse gases. Now the problem seemed even harder.

Extra heat won't be good for the animals we eat and get milk from; it will make them less productive and more prone to dying young, which in turn will make meat, eggs, and dairy more expensive.

Fifty-one billion is how many tons of greenhouse gases the world typically adds to the atmosphere every year.

With the price of today's batteries, EV owners save money only if gas costs more than around $3 per gallon.
