Quotes about Energy

times with follow-up questions. Eventually it sank in. 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. It wasn't enough to deliver cheap, reliable energy for the poor. It also had to be clean.

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.

In the coming years, as electricity becomes an even bigger part of our overall energy diet, we'll need models like these for grids around the world. They'll help us answer questions like: Which mix of clean energy sources will be the most efficient in a given place? Where should transmission lines go? Which regulations stand in the way, and what incentives do we need to create? I hope to see a lot more projects like this one.

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.

Getting all the world's electricity from clean sources won't be easy. Today, fossil fuels account for two-thirds of all electricity generated worldwide. (bp Statistical Review of World Energy 2020)

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

Nuclear power kills far, far fewer people than cars do. For that matter, it kills far fewer people than any fossil fuel.

The United States gets around 20 percent of its electricity from nuclear plants; France has the highest share in the world, getting 70 percent of its electricity from nuclear. Remember that by comparison solar and wind together provide about 7 percent worldwide.

High-profile accidents at Three Mile Island in the United States, Chernobyl in the former U.S.S.R., and Fukushima in Japan put a spotlight on all these risks. There are real problems that led to those disasters, but instead of getting to work on solving those problems, we just stopped trying to advance the field.

Natural gas followed a similar trajectory. In 1900, it accounted for 1 percent of the world's energy. It took seventy years to reach 20 percent. Nuclear fission went faster, going from 0 to 10 percent in 27 years.

Making Carbon-Free Electricity Nuclear fission. Here's the one-sentence case for nuclear power: It's the only carbon-free energy source that can reliably deliver power day and night, through every season, almost anywhere on earth, that has been proven to work on a large scale.
